Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

1. INTRODUCTION
1.1 Solar Energy
“Since human was born, peoplehave been exposed to the sun. The ancient
of Egypt civilization used sun as a god, called the solar deity. Throughout
the history, the sunlight has become the important sources for farmers to
grow plants and fruits.” (Susan,2013) The sun is a pure, infinite energy
source for us throughout the years, the earth needs sunlight to survive so
do we human. If earth does not have sunlight, crops do not grow and with
no food, animals find it hard to survive. With power of heat and light from
the sun, in recent years we people have developed technologies to better
use the solar energy. This technology not only has brought upon the most
important energy sources, it could also replace non-renewable energy such
as fossil fuels and so on. Many years, people have used the fossil fuels,
coals and also nuclear power toprovide electricity and other purposes. This
kind of non-renewable energy has been bringing consequences to our
human. As reported by Economist, “In 2014 it still had a share of 31%,
compared with 29% for coal and 21% for natural gas. Fast-growing rivals to
fossil fuels, such as wind, solar and geothermal energy, together amounted
to little more than 1%.” (The future of oil,2016). (Figure 1)
Figure 1. Global primary energy consumption percentage (The future
of oil,2016)
5. 5
This means that fossil fuels have been a primary energy for recent years
and it is high on demand. Because of it is a non-renewable energy, the
fossil fuels will be running out with current rates of production. So
nowadays people have always looked for ways to develop other energy
sources to replace the fossil fuels, one of the most promising energy
sources is the solar energy.
Solarenergy is a form of energy which produces by the sun rays, it is a solar
radiation which transforms into solar electricity and heat. There are two
types of solar technologies, photovoltaics and thermal. Photovoltaics
technology uses sun rays and directly invert it into electricity. On the other
hand, solar thermal technology uses the heat from the sunrays and uses it
directly. It provides energy to various applications meant for heating
purposes such as hot water supply.
Buildings nowadays need solar energy to provide lighting, heating purposes
and electricity. Solar energy comes in twoforms, active and passive forms.
Figure 1.1 Different solar technologies covering different building
needs
According to this picture (MC Munari Probst & C Roecker,2012) (Figure 1.1),
we can know that
Domestichot watersystem can be provided by using the solarthermal
system.
6. 6
Heating can be provided by passive(direct) solar through building
from windows and doors. It can also be produced indirectly from solar
thermal system.
Electricity for household items are provided by the solar technology
of photovoltaics.
Light can be provided by the passive(direct) sunlight using windows
and electric lighting also can be provided by electricity from
photovoltaics technology.
At night, ventilations are available through the windows (passive
night ventilations) for free cooling.
1.2 Photovoltaics
Photovoltaics solar technology absorbs the sun rays and directly converts
it into electricity using the solar panels made from semiconductor cells.
Photovoltaics(PV) can be installed in different ways. For an example,
ground-mounted or installation on the roofs and walls of a building are
called BIPV (Building Integrated Photovoltaics). There are three types of
photovoltaics panels, which are cell, module and array. “PV cells are
associated into parallel circuit to create high voltage of electricity. PV
modules consists number of PV cells together in a protective laminate.
Finally, PV array is a completeelectricity generating unit with combination
of few PV modules and PV cells.” (FSEC, n.d) (Figure 1.2)
Figure 1.2 Types of Photovoltaics
7. 7
1.3 Rationale
In recent years, passivesolar have been used in most of the building design.
It is very common tohave passivesolar in our building. Now or in the future,
we need to integrate the building by using active solar in order to reduce
the consumption of fossil fuels and also the use of non-renewable energy.
Not many of the countries have developed the active solar technology
especially those developing countries. On the contrary, some of the
countries like US, Canada, Sweden have developed their active solar
technology and integrate them into building design. Many of the citizens
gave positive feedback on the active solar technology. However, Malaysia
and some developing countries have yet developed the technology
probably due to financial and political issues.
This research is important as solar energy is popular and reliable when it
comes to replacing non-renewable energy. As mentioned above, solar
energy is a clean and powerful energy resource on the earth. With the
matter of pollutions and other environmental issues from non-renewable
energy, solar energy is very beneficial for future lifestyle and next
generation too.
1.4 Scope
Though there are two types of solar technologies which are photovoltaics
system and solar thermal system, the scope of this research is more on
photovoltaics. This is because it is more widelyused in building integration.
Listed below is a more detailed scope of the research topic:
The installation process of photovoltaics
Management system (software, how to manage the solar energy
system)
The advantages and disadvantages of solar energy used in buildings
The possible problems faced in the system
Recommendations for future improvement on photovoltaics
Case studies with more in-depth explanation and findings about the
integration of photovoltaics system into our buildings.

2. INSTALLATION PROCESS
2.1 Engineering site visit
Sunrun (2017) mentioned that the first thing the solar panel company does
is to send an engineer to a client’s home to evaluate the electrical status
of the home and also to make sure their energy system is compatible.
Besides that, Richardson, L(2017) mentioned that the engineer uses a tool
called “Solar Pathfinder” to find out how much sun the panels are likely to
able to capture. After that, the engineer also evaluates the condition of
the roof to make sure that it is stable. After passing all the tests, the solar
panel company discusses with the client and assesses how powerful the
client expect the system to be and also budget. However, the solar
company makes sure that the client would have at least 3.5kWh system to
make the solar energy worthwhile.
Figure 2.1 above shows a Solar Pathfinder (Solar Pathfinder, n.d.)
2.2 Installation of inverter
According to this article entitled “What is the process of installing solar
panels on your roof?”, it was mentioned that an inverter is a device that
collects the electricity generated by the solar panels and sends it to the
grid. Installation of the inverter is a compulsory because the current
generated by the solar panels is direct current (DC) while the grids runs on
alternating current (AC). The inverter is usually installed on the home wall
and it is important tomake sure that the home poweris disconnected while
installing the inverter. The lifespan of the inverter will only last for 10
years while the solar panels will typically last for at least 25 years.
Therefore, a inverter needs to be replaced every 10 years (what is the
process of installing solar panels on your roof, 2017).
9. 9
Figure 2.2 above shows an inverter
2.3 solar panel installation
Gevorkian, P. (2014) mention that the solar installer will start by prepping
the roof to makesure that the shingles or tiles are properlyattached. After
that, they will install the wiring that connects to the electrical panel and
general power system. After the electrical wiring is complete, they will
start to install the racking support for the solar panels. Roof-mount solar
powerinstallationare madeof either tilted or flat-typesupport structures.
If the client has flat roof, then installing the panels will take a little bit
longer as they will need to be mounted at an angle.
Figure 2.3 above shows a prefabricated PV module support railing
system used for roof-mount installation. (Gevorkian, P., 2014)
When installing roof-mount solar panels, care must be taken to meet the
proper directional tilt requirement. Another important factor to be
10. 10
considered is that solar power installation should be located in areas free
of shade which could cause by adjacent building, trees, or air-conditional
equipment. In the event of unavoidable shading situations, the solar power
PV module location, tilt angle, and stanchion separations should be
analyzed to prevent cross shading.
Once, the racking is safely attached, the panels are placed onto the racking.
Finally, the inverter is connected to the panels to convert direct current
(DC) energy into the alternating current (AC) energy used in homes and on
the electric grid.
2.4 Installation of battery
For buildings that uses off-grid solar system, battery is needed to store the
excess electricity generated by the solar panels for later use. Unlike many
electrical apparatus, standby batteries have specific characteristics that
require special installation and maintenance procedures. If not followed
correctly, these can impact the quality of the battery performance.
Gevorkian, P. (2014) stated that Lead-acid and NiCad batteries must be
kept dry at all times and in cool locations. Therefore, batteries must be
mounted on open racks, on steel, fiberglass racks or enclosures. The racks
should be constructed and maintained in a level position and secured to
the floor and must have a minimum of 3 feet walking space for
maintenance.
Figure 2.4 above shows a battery rack
11. 11
2.5 Installation battery charger controller
Gevorkian, P. (2014) also mentioned that a charge controller is essentially
a current-regulating device that is placed between the solar panel array
output and the batteries. These devices are designed to keep batteries
charged at peak without overcharging, hence prolonging the batteries
lifespan. Most charge controllers incorporate special electronics that
automatically equalize the charging process.
Figure 2.5 above shows a battery charger controller
2.6 Approval and interconnection
Before you can connect the solar panels to the grid, a town government
representative will need to inspect the client’s system and give approval.
Richardson, L (2017) mentioned that the representative will need to
double-check the installer’s work, if electrical wiring was done correctly,
whether the mounting is safe and sturdy and overall instalment meets the
standards of their policy. After the final evaluation, as long as there are no
issues, the system is ready to be installed.

3. MANAGEMENT SYSTEM – INTELLIGENT ENERGY
DISTRIBUTION SYSTEM
AG, S. S. (n.d.) commented that Intelligent energy distribution system is
used to determine how effectively the power generated from renewable
sources are distributed. With this system, you are able to monitor your
energy usage and ableto reduce both energy wastageand money on energy
bills. The system is able to decides when to use the energy stored in the
battery.
When the power generated from the commercial electricity grid is low,
then it will switch to the solar grid. P. Nagalaxmi (n.d.) mentioned that if
the energy generated from the solar panel is sufficient then powersupplied
as usual as the commercial grid otherwise controlling action takes place.
The energy stored in the batteryis always compared withthe present levels
and if it is low then it communicates with control room to take necessary
steps. P. Nagalaxmi (n.d.) also suggested that according to the energy
levels in the stored battery the controlling of devices takes place. If the
energy level is below the first present level then the power that goes to
the least priority devices are automatically shut off and the high priority
devices are run and if the energy is below that then the next priority
devices are shut off and allows to run only the highest priority devices
giving a signal to take the necessary actions.
M. Veda Chary (n.d.) mentioned that as the consumption of power
increases, the energy stored in the batterydecreases causes that no longer
the devices operate with the solar energy. In order to increase the
efficiency of the solar system it is required to distribute the energy
intelligently, sends a control signal from the control room to turn off the
least priority devices and keep on monitoring the battery status. M. Veda
Chary (n.d.) also mentioned that if the battery value reaches the threshold
value which is set for safe operation runs only the highest priority device
making all remaining devices turn off.

4. ADVANTAGES AND DISADVANTAGES OF SOLAR
ENERGY
4.1 Advantages
4.1.1 Renewable source
The most important and essential thing about solar energy it that it is a
renewable source of energy. It can be used in most part of the world and
can be used every day. It is different from other sources such as fossil fuel.
As long as the sun is present, humans will still be able to harness solar
energy from the sun. In the article “Pro and Cons of Solar Energy”,
according to scientists, the sun has a life span of at least 5 billion years.
So, if used by humans as an alternative energy, solar energy will be
available for a very long time.(2017)
4.1.2 Reduces electricity bills
As electricity will be produced from sunlight, there will be a consequent
decrease in the electricity bill each month. Using solar energy is a good
way to fight against the cost of living which is continuously increasing. The
use of solar energy will also reduce our dependence from conventional
energy sources. In the article “Pro and Cons of Solar Energy” mentioned
that if the solar panels generate more energy than we use, we can sell the
energy back to our provider to make money. (2017) However, the amount
of solar energy collected is proportional to number of solar panels installed.
So, an optimum number of panels must be installed to maximise saving of
energy and reduction of bills.
15. 15
4.1.3. Applications
Figure 4.a.3 The Mauritius Commercial Bank- Ebene
Solar energy can have various uses. As mentioned above, it can be used to
generate electricity and heat water. Also, it can be used to refine water in
regions with limited clean water supplies. Solar energy can also be
integrated into the materials used for buildings, for example the Mauritius
Commercial Bank (Figure 3.3) found in Mauritius. Photovoltaic cells
installed on the windows of the buildings generate power from sunlight
which relieve the country’s pressure on power load.
4.1.4 Low maintenance costs
In general, systems using solar don’t require a lot of maintenance. The only
real need is to keep them clean, so cleaning them several times a year
should be enough and a system check can be performed yearly, just to
make sure that everything is working as it should. Adding to the fact, as
there are no moving parts present in the panel systems, damagefrom wear
and tear will not be a problem. The only part that needs to be changed
(after 5-10 years) is the inverter as it is continually working to convert the
16. 16
solar energy to electricity. So, after having covered the initial cost of the
solar system, there will not be much cost in maintaining the panels.
4.2 Disadvantages
4.2.1 Initial cost
One of the main drawbacks of using solar energy is the cost of installing
enough solar panels to harness energy for a whole house. Although it will
save you money on the long run, its initial cost is fairly high (payment for
solar panels, inverter, batteries, wiring, installation). Also, Rinkesh (n.d)
mentioned that the time taken to break even with your investment is
around 10 to 15 years long but, anything that can help to conserve the
environment and decrease our dependence on fossil fuels is worth trying.
4.2.2 Climate and region dependent
Figure 4.b.2
As solar energy is dependent on sunlight, and all regions on earth don’t
receive the same amount of sunlight. So, in regions which barely receive
sunlight, it is not advisable to install solar panels as it will be a wastage of
funds. Furthermore, efficiency of solar system is reduced during cloudy,
foggy and rainy days. "[T]he solar resource during foggy or low-cloud
conditions is approximately 10% of the value under clear-sky conditions."
(Nick Gromicko, n.d). Continuous rainy days can be a problem and also,
solar energy cannot be created at night. This problem can be countered by
17. 17
the use of large batteries which will store the energy generated. However,
these batteries are expensive but it’s a good investment.
4.2.3 Materials used to make solar panels can cause pollution
Materials present in solar panels which can be dangerous for the
environment are cadmium and lead. When sealed properly inside solar
panels, cadmium is harmless. According to article, “Cadmium Telluride –
The Good and the Bad” The real problem will arise if there is any leakage
in the panels as cadmium is among the top 6 deadliest and most toxic
materials known. (2010). As for lead, it is also a very dangerous and it can
seriously damage the nervous system and brains of unborn children.
However, most of the material used in dead batteries can be recovered
provided the consumers make the effort. Also, compared to other sources
of energy, the pollution cause by solar panels is negligible.
18. 18
5. POSSIBLE PROBLEMS TO THE SYSTEM
5.1. Panel cracking
Panel cracking can be caused by many ways. Physical impacts, oscillation
from wind, or manufacturing issues can cause cracking. “Panels should be
inspected on purchase because there could be micro cracks created during
the manufacturing or shipping process that will grow into larger cracks over
time.” (Djordjevic, Sinisa, David Parlevliet, and Philip Jennings, 2014).
Cracks will reduce module vitality yield and effectiveness. This is because
that the cracking will change the optical properties of the board, and make
light infiltrate the surface of the board in an unexpected way. This prompts
loss of proficiency because the greatest measure of light is not entering
the board. Contingent upon the measure of breaking, infrequently it is not
justified to purchasing a whole new board. Typically, additional boards are
requested at whatever point a system is acquired, and for this situation it
could be worth using these boards to supplant cracked ones. Else, it would
not be worth purchasing an altogether new board to supplant ones with
cracks.
FIGURE 4.1.1 ABOVE SHOWS A CRACKING PANEL.
19. 19
5.2.Panel discoloration
Panel discoloration is a common defect that will decrease the amount of
sunlight that penetrate a solar cell. This is meant that the panel generate
less energy. For instance, purple discoloration, such as in (Figure 4.1.2) ,
means that purple light is not absorbed by the panel. This causes loss of
efficiency because not every wavelength of light is being absorbed.
Different types of semi-conductor materials absorb different wavelengths.
“Some examples that cause discoloration are poor encapsulate quality,
high temperatures, humidity, and if a PV system is located near an ocean:
ocean salt.” (Djordjevic, Sinisa, David Parlevliet, and Philip Jennings,
2014). Like panel cracking, there is very little you can do to decrease the
impacts of discoloration once it has happened, other than replacing the
panel totally. Higher quality panels will progress toward becoming stained
less effortlessly. There is not a correct technique to perceive how much
power is lost, other than looking at the vitality yield previously, then after
the fact discoloration has happened.
FIGURE 4.1.2 ABOVE SHOWS
DISCOLORATION PANELS.
20. 20
5.3. Soiling
Soiling is one of the most serious issues in dusty environments. It is very
expensive and the only way to deal with it is to clean the panel. On a large
commercial array, heavy soiling could warrant multiple cleanings a year.
At a cost of twoor three thousand dollars a cleaning, doing this consistently
for a PV frameworks life expectancy can be extremely exhausting, and in
many occasions, can even debilitate the change to solar. One of the most
ideal ways one can manage soiling is to battle it before it even happens.
One can do this by performing due steadiness and checking whether panel
cleaning goes under guarantee. Also, according to Mejia and Kleissl, out of
186 sites, each site was found to have losses greater than .01% per day,
over double the average. This is
because the tilt angles were less
than 5 degrees. Tilt angles less
than 5 degrees were shown on
average to have 5x more soiling
than ones that were tilted
more than 5 degrees. If you
are in a very dustyenvironment
it would be well worth it to
consider a higher tilt angle
even if maximum solar
irradiance is gained from an
angle of 5 degrees or lower. This is because after some time there will be
less soiling, and at last you will create more vitality over the long haul, and
not cleaning as regularly. There is just so much you can do to battlesoiling
before you need to clean panels. Finding an expert solar cleaning
organization is the best choice when it comes time to cleaning panels.

5.4 Storm/snow load.
The respective standards especially for storm
and snow load are to be considered and are
to be matched with the local conditions or
requirements. Also, expert Prof Ir Dr Mohd
Zainal Abidin Ab Kadir (2016) said that
Malaysia is the third highest lighting strikes
country with an average of 180 to 260
thunderstorm days a year, after Indonesia
(322) and Columbia (275 to 320).
5.5 Theft
Smart thieves always know the expensive things. Hence, product should be
securely installed against theft (also roof mounted PV plants). According to
this
research “Construction and Operational Covers for Photovoltaic Parks”,
Theft proof screw connection should always be used. (2011). An adequate
fencing and CCTV shall be provided for ground mounted PV plants.

Bites of rodents are not completely avoidable. To prevent marten bites,
necessary protection must be taken. (“Construction and Operational

overvoltage protection must be installed. (“Construction and Operational

6. CASE STUDY
A case study of solar photovoltaic power system at Sagardeep Island, India
The application of renewable energy in electric power system is growing
fast. Photovoltaic and wind energy sources are being increasingly
recognized as cost-effective generation sources for remote rural area
isolated power system. Sagardeep Island in West Bengal state of India
installed solar photovoltaic (SPV) system and the performance is analysed
by using commercial parameters. SPV installations have provided
electricity to people but also raised their standard of living (Ravindra M &
Prakash S, 2007).
Based on 2001 census data, 43.5% of Indian rural households have access
to electricity. Due to high cost of installation of electric lines, Villages in
remote areas are not connected buy the electric lines as it is not possible
to lay the line in some isolated areas. There are about 94,000 un-electrified
villages (around 25,000 villages are placed in remote geographically
isolated areas where extension of existing electricity grid it not
economically viable (census of India, 2001).
Presentlythe capital cost of photovoltaicsystem is about $4000 kW1, while
the cost of conventional power system such as oil, gas and coal is
approximately four times lower. But the operating cost associated with
these conventional plants is unacceptably high due to escalating fossil fuel
costs. Considerable fuel savings can be achieved by integrating renewable
sources such as wind and/or solar energy with existing diesel plants.
Though photovoltaic (PV) is far from being economic in comparison to
conventional fossil fuel for providing electricity, it is used in remote areas
where it is uneconomical to extend the electric grid. However, the market
for PV is also expanding rapidly due to reduced manufacturing cost of PV
systems during the last decade (Phuangpornpital N & Kumar S., 2007).
24. 24
In order to decrease the diesel consumption, wind turbine generator (WTG)
is operated by using wind and solar energy in remote areas and/or the PV
unit in parallel with diesel generators resulting fuel save. This particular
operation suits for systems with relatively small renewable energy
penetrations (Infield DG, Slack GW, Lipman NH & Musgrove PJ, 1983).
There are several researchers who contributed their papers on solar
photovoltaic (SPV). Rahman & Chowdhury (1988) showed number of
photovoltaic performance analysis models and their impact on electric
utility’s load shape under supplyside peak load management conditions for
eastern and western parts of US and cost saving effect of battery bank.
Sagardeep Island is located at latitude 22.658N and at longitude 88.458E.
A MATLAB program is developed to predict the solar radiation at the site.
Figure 5 shows the (i) predicted values and (ii) 5 years monthly radiation
data from 1998 to 2002.
Figure 6.1 shows that the dc power generated by an array and stored in
twolead acid battery banks (each of rating 2 V 800 Ah) during daytime and
discharged during night time from 6 p.m. till the charge of the batterybank
reaches to 20% of its rated value or midnight whichever is earlier.
Additional power if available may be supplied in the morning hours from 4
25. 25
to 6 a.m. DC power is converted to ac power through inverters (3 15 kV A)
and is connected to the consumer load through feeders (230 V, 50 Hz ac
supply). The arrangement has three feeders, one feeder for plant and other
two are for consumer loads. The system implements protective schemes
including air circuit breaker (ACB) and minimum oil circuit breaker (MOCB)
(Ravindra M & Prakash S, pg. 673-681, 2007).
Figure 6.2 gives the seasonal load variation at Sagardeep Island. It is
observed that during the summer season power requirement is high
because both lighting and fan load is increased. During the winter the peak
requirement is during 6–7 p.m. slot and load gradually reduces, as the day
length is small. During summer season the day length is more and the peak
occurs during 8– 9 p.m. slot. During rainy season only lighting load is
required to be supplied (Ravindra M & Prakash S, pg. 673-681, 2007).
26. 26
Fig. 6.3 represents the power generation minimum, maximum and average
value. It is observed that during summer season when sky is clear on
maximum days the minimum output is above average value (Ravindra M &
Prakash S, pg. 673-681, 2007).
Fig. 6.4 shows the loss of load hours during different months (Ravindra M
& Prakash S, pg. 673-681, 2007).
27. 27
28 kWp-installed capacity plant contributes electricity to households
within 4.5-5k km radius where each plant averagely has 100 consumers.
These plants are managed by rural cooperatives, and the revenue
collection method is through the account of the cooperative society in the
Rural Development Bank. Smart cards are being introduced for prepaid
services, as well as an automatictripping device to prevent consumer from
drawing excessive power than permissible limit (Ravindra M & Prakash S,
2007).
Around 2500 families are now enjoying electricity from SPV. The power
supply at night has helped society in at least four ways. It has helped (i)
the students to continue their study at night, (ii) the shopkeepers,
cultivators of betel leaf to continue their work at night (iii) the people to
avail themselves of the entertainment facilities and (iv) the women to do
the household work. The supply of solar power has also helped, though on
small scale to run the video hall, battery-charging center, etc. Streetlights
make the island safer at night. Two hospitals on the island now have a 24-
h supply of energy (Ravindra M & Prakash S, 2007).
Well-established technology, simple operation and main- tenance,
downward trend of cost, optimum resource availability in remote and
island areas, environmental sustainability, good management systems,
etc., are indications of large scale installations of solar power plants in
near future at Sagardeep Island. With the demand not exceeding 20–25 kW
at a load factor less than 30% and where conventional power cannot reach
as techno-economically viable proposition, SPV system will offer a
competitive option there. Acceptability of system by the people both on
commercial operation and quality of power supply are guiding principles.
The fee for service payment model is effective (Ravindra M & Prakash S,
2007).

7. FUTURE DEVELOPMENT OF SOLAR ENERGY
7. 1 Solar Tracking Mounts
Figure 7.1 Cartier-Bresson (2015) .New York ,NY
Recently as the usage of solar is on the rise ,there are many homeowners
are considering to use solar ,although there are roofs which are less than
ideal for panels .The usage of solar tracking mount can be considered in
order to maximize the efficiency of electricity production by following the
direction of sun because it moves along the sky .Based on a
research ,scientists of United States (n.d) says that solar panel tracking
systems are more advanced compared to mounting PV panels .The
advantage of using this system is that when the sun passes to a less-than-
optimal angle and the solar trackers are automatically moving to “track”
the progress of the sun across the sky .Generally ,trackers generate more
electricity due to the higher rate of the direct exposure of sunlight .The
increase of 10-25% electricity depending on the geographical location of
the tracking systems .
29. 29
7.1.1 How does a solar tracker work ?
Figure 7.2 Solar Tracker
Kathie Zipp (April 4,2013) states that in photovoltaic system ,trackers are
able to minimize the angle of incidence between the incoming light and
the panel ,which helps to increase the amount of energy the installation
procedures .Single-axis solar trackers rotate on one axis moving back and
forth in a single direction .Dual-axis trackers continually expose to sun due
to the movement of different directions .Dual-axis tracking is typicallyused
to orient a mirror and redirect sunlight along fixed axis towards a
stationary receiver .Due to the trackers are following the movement of sun
vertically and horizontally so they will help obtaining maximum solar
energy generation .
30. 30
7. 2. Solar Thermal Fuel (STF)
Figure 7.2 David L. Chandler | MIT News Office (April 13 ,2014)
It acts as an alternative storage for solar .The technology and process of
the STF is comparable to a typical battery .Grossman T. (n.d) says that the
STF is able to utilize sunlight energy ,store it as a charge and then release
it when prompted .The dissipation of heat is the issue with storing solar
energy as heat and that’s why the solar storage is able to charge energy
rather than capture energy .STF has energy density of lead batteries .Solar
thermal energy generally converts solar energy to heat and could use that
energy for generating power for several hours even if the sun has gone
down .
31. 31
7.3 Solar Water Purifiers
Figure 7.3
Stanford University researchers collaborated with the Department of
Energy (2016) ,United States stated that they are developing a new solar
device that can purify water when exposing to sunlight .Prior purifiers
design needs to utilize UV rays and requires the exposure of sunlight for
hours to fully purify the water .In addition ,Stanford’s new product is able
to access visible sunlight and manages to produce drinking water within
just few minutes .
32. 32
7.4 Nano Solar Technology
Conventional solar cells based on photovoltaic technology is commonly
used worldwide .However ,there’re still missing a big chunk of the
electromagnetic spectrum .Ryan Whitwam (Oct ,2013) states that the
researchers have started developing a new nano-material which could acts
as a “thermal emitter” ,increasing the efficiency of the solar energy by
scooping up more of the waste energy .The conversion of the solar cells to
electricity would be easier with the infrared part of lights and the thermal
emitter approach works within that framework .A thermal emitter isn’t a
parallel system to derive the electricity directly from the sun’s
rays .Instead ,this is an application of thermophotovoltaic
principals .Generally thermophotovoltaic refers to the production of heat
from light .The thermal emitters consist of two parts ,which are the
tungsten-based absorber that heats up when exposing to light .The heat
energy has been taken up by the emitter component and is used to output
infrared light with higher efficiency compared to the current silicon
semiconductor solar cells .
Figure 7.4 Nano Solar Technology
33. 33
7.5 Solar Skin Design
Figure 7.5
There’s a high percentage of homeowners consider solar panels to be an
unsightly home addition and it’s one of the major problem for a solar
industry .Fortunately ,Sistine Solar ,a Boston-based design firm has a new
solution ,which is making major strides with aesthetic enhancement
concept that allow the panels for having a customized look .The creation
of “Solar Skin” has been produced in order to match the appearance
between the solar panels and the roof without affecting the panel
efficiency and production .The solar skin panel is said to be in U.S market
in few more years soonest .
7.5.1. Efficiency of solar production
More efficient semiconductor materials need to be discovered by the
scientists in order to increase the efficiency of the solar
production .(Problems with solar energy – why its is not widely used ,n.d)
mentions that lesser space is required to produce the same amount of power
when doubling the efficiency of a panel due to the size of the array which will
in turn .T. Alfred (n.d) states that other than increasing the efficiency of the
solar production ,mass production of panels inefficient factories should also
reduce the cost of the productions in order to make them more affordable for
the consumers .

LIM HAO ZHENG 0327115
First of all, I would like to thank to my group members for their full cooperation and
commitment of their work. Thanks to my one of the group members, Wen Jun because
he is able to invite us to his uncle’s house to do some research about the solar energy.
This visit has surely helps us a lot on our assignment. This assignment helps me a lot on
my research skills as well as learning more about citation. I am also able to learn and
gain knowledge on how photovoltaics works and picture life in the future if we use solar
energy as a permanent source of energy. Wen Jun’s uncle mentioned a lot about the
future of solar energy, I am surely that this kind of source can be successfully developed
and fully integrate into our building, is just a matter of time. In the beginning of the
assignment, we have difficulties of choosing the topic, and we finally made up our mind
by choosing “Building integration of Solar energy” as our assignment topic. I only knew
solar energy as a source to provide water heating in our houses, but after doing much
research and visiting Wen Jun’s uncle, I am able to know more and discover more about
solar energy. It is not just about heating the water, it could do way more than that such
as converting it into electricity to provide lights and electric to our household items. I
think solar energy is a very clean and green energy source compare to fossil fuels.
Finally, I would like to give my appreciation to the uncle who has taught us a lot about
solar energy and how solar energy integrates into our building. I hope in the future we
will have solar energy to fully integrate in our building and to be a replacement of
primary energy source.
SOW WEI HENN 0324998
Through this assignment ,I have a clearer understanding on the Solar Energy .I am able
to differentiate the different types of solar energy such as photovoltaic and solar
thermal .I also know that photovoltaic technology directly converts sunlight into
electricity whereas the solar thermal technology captures the sun’s heat .This heat is
used directly or converted into mechanical energy and in turn electricity ,known as
concentrated solar power .Besides that ,I also know some efficient ways for the
improvement of the solar energy in the future .Enhancing knowledge is also one of the
lessons that I got after completing this assignment .In addition ,I have also realised that
communication skill is very vital especially in a group project in order to avoid any
unnecessary conflicts .Apart from that ,being cooperative is the key to
success .Cooperation among the group members enable the works to be done smoothly
and also in a shorter time .Last but not least ,I have found out that solar energy is not
widely used in our country although it comes with a variety of
advantages .Consequently ,government plays an important role to encourage the usage
of solar energy in our country .

This project for me had many highs and lows. Since the very start, I was very excited
as I have always been for the protection of our environment and throughout the project,
I’ve learnt that solar energy is really recommendable for our environment. Also, this
project has helped me grow into a better person. Each meeting increased our team's
bonding and each meeting helped me to develop my communication skills and to convey
my ideas in an efficient way. We went to meet Wen Jun’s uncle who has great
knowledge in solar panels. Moreover, I also developed my research skills: to find,
extract and use information efficiently. It is one of the most interesting assignment as
I had to find whether solar energy is beneficial or not, and to conclude, it’s highly
recommendable for humanity.
SHUM WEN JUN 0325151
Through this assignment, I have better understanding how a solar energy system works
in a building. I can now differentiate the difference between on-grid system and off-
grid system of solar energy which I previously do not know this thing exist in solar energy
system. I am also able to learn about the advantages of using solar energy system in
building. Solar energy is actually environment friendly, but the initial cost of investment
is very high. Lastly, I also learnt how to work with teammates to finish this assignment.
Communication is very important as it can combine our thoughts together to create an
awesome outcome.

HENG YI CHENG 0327895
For this assignment, we have learnt many things from it. For me, I have learnt about
how solar energy works to make a better life for human, and it is also an investment
that capital can be earned back by several years and start earning some profit although
it is a very expensive system to install. Moreover, this project helps me to develop my
communicating skills, research skill and skill of understanding. From the beginning, I do
not even know what is AC and DC until I ask my group mates and do some research
about it. Lastly, I very appreciated that I can get to know more about solar energy by
this project.
NG KAI CHUN 1101G13410
Thorough this assignment, I have learned a lot of things about solar energy such as
installation process, management of solar and so on. In order to gain more knowledge
about solar panels, my team and I paid a visit to a professor’s house who using solar
panels as electricity supply of his house. He explained to us how solar works and how
solar might affect thorough globally. I was amazed how solar can change our lifestyle
completely by substituting electric panel which provided by Tenaga Nasional Malaysia.
However, it is not fully utilised and introduced by the government due to the technology
we are lack of. In term of cost, solar contributes cost saving in long term as the cost of
installing solar panel is expensive. However, it is recommended by household to install
solar panels in order to save cost economically. Last but not least, I want to thank our
lecturer, Mr. Leong for giving me the opportunity to approach new things that I have
never learned before.

Appendix 1: Interview transcript
The Solar Photovoltaics System
J: What is this actually?
F: This is the controller which is called the synchronizer of this system.
J: How does this solar photovoltaics system works and any rules for this things in
Malaysia?
F: My solar system is a DC current then invert it into AC, then we synchronize it
and provide electronic power. This power I must export out. Those day when
there is excess power then only I sell to Tenaga Nasional Berhad. Now new
regulations that I must sell to TNB first, then if I need to use it I only buy back
from TNB.
J: Can you please explain the display of the controller and what are the purpose
for solar photovoltaics system?
F: This controller is advanced, it can detect whether it has any short circuit or
not on this system. Currently it displays of the resistance is 8.5 ohm. Today the
system is producing 1.998 kW of the solar energy because today is a bit cloudy
so the sun light is not so powerful. (Figure 10.1)
Figure 10.1 Solar energy produce per day
40. 40
This system can produce 6kW maximum per day. Now it display the DC current
voltage and this is the grid frequency for the TNB one.(Figure 10.2)
Figure 10.2 Displaying the voltage of DC current and grid frequency of TNB
This one is the voltage that TNB produce so my solar will need to match the
voltage same as TNB, is adjustable by this solar photovoltaics system. If TNB
voltage drop to 240V then my solar controller will automatically drop to
240V.(Figure 10.3)
Figure 10.3 Displaying the TNB Voltage and the system voltage.
J: What number of kilowatt can produce by this system in highest peak and the
peak of the day?
41. 41
F: From few years ago till now, the highest peak of kilowatt can produce by this
system is about 6.14kW.Today the highest peak is about 3.969kW.(Figure 10.4)
Figure 10.4 Highest peak of all year and the peak of the day
J: Still got any display of the controller you can explain?
F: You can see the controller, it can also the display the temperature of the
system.(Figure10.5)
Figure 10.5 The temperature
You know the power factor? Actually the power factor less than 0.5 will get a
penalty from TNB means you waste energy. TNB wants you to generate at least
85% of the energy efficiency, less than 85% will get penalty. You can see the
display of the info, power factor is 1 means my solar system is 100%. (Figure
13.6)
42. 42
Figure 10.6 Power Factor
Now it displays power out, 2.1kW, I can run water heater, air conditioner,
electric fan and lights and so on. Now my solar system already generates
32000kW in 5 years. So, I have another 2 more years to get my investment back.
(Figure 10.7)
Figure 10.7 Generates total power in 5 years till now
J: How do you get your investment back and this system cost you how much?
F: I get back my investment by generate the power and sell it to TNB, so now I
already generates 33000 unit, I sell to TNB for one unit about RM1.35 and now I
already get back RM42k. This system cost me about RM60k for installation. Two
43. 43
more years, I just need to get back RM18k then I can use it for my whole life with
this system.
J: What are the benefits with using this solar photovoltaics system?
F: The main benefits is the economical. If I don’t want to install , my monthly
usage I need to contribute the electric cost fee and the expenditure and I can’t
get any money. If I install this, I will have one time investment and I get back my
capital fees and I can still use for another 21 years. The electricity fees I already
save a tons on it, the solar have given much benefits to ours especially the
electricity cost. Now this system no more sold in the market because Najib has
close this kind of investment.
J: This solar photovoltaics system has another name, what does it call?
F: This system called grid-tied system.
F: This is the solar system I use for myself not TNB which is the OFF-Grid system.
(Figure 10.8)
Figure 10.8 OFF-Grid System
J: This system use to generate for?
F: This off-grid use to generate electricity for computers, television, LED lights,
hot water system and many more using the solar energy to save money. I just
44. 44
using air conditioner for TNB, other is using OFF-Grid system from solar energy.
Another is ON-grid system which is from TNB, I sell the power to TNB and buy
back from TNB using solar also.
J: The excess power which generate from this system, where did it flow to?
F: Let’s say that I have generate 12kW in total, the excess power will be given
to neighbors to utilize it. They also get use to my solar power.
J: This solar photovoltaics system is so good but why Malaysia still not develop
to our citizen to use the solar energy for electricity?
F: This system is good to ours but the government restrict not to encourage to
citizen because it will affect the Tenaga Nasional Berhad profit. Because those
capitalize country will always take care of those monopoly company, everything
will give to corporation. So this is the big problem to this world for now. Some
of the country do this kind of thing is illegal to them even United States is not
allow in certain states because the corporation will get angry on it.
J: Many people say solar provide electricity not so good because of night time
will blackout, recommend fossil fuels and nuclear power etc., is that true?
F: People say solar is not good is a false, at night will blackout is nonsense. You
see the earth is rotating everyday, at Sabah 6am the sun rises, while you sleeping
in KL the Sabah already have sunlight, the solar energy can channel through the
sea, with submarine cables. When sun goes down around here, in Europe the sun
rises ,sunlight there is very strong, starting to produce sunlight, Europe can
transfer the power to our site. When in the Europe in the night time, the US
there can produce solar energy to Europe, one of the issues is the political issues.
J: Who provide us the future and the electricity of AC, those electrical
equipment?
F: You know Tesla? In nowadays history books don’t have Tesla this man only
have Mr. Einstein, Maxwell and so on. What ever you enjoy today,you must say
thank you to Tesla because before he died he said your future is my future, he
invented the radio control, transformer, voltage , AC , laser and many more.
Because he is not American, is a Croatian. American don’t like him so America
suppress him.

J: What is the steps for Photovoltaics(PV) from solar energy transform into
electricity?
F: Photovoltaics absorbs the heat radiation becomes the DC current and go
through a charge controller(cc). The function of charge controller is to charge
the battery, You can’t use PV direct to the battery, because it will damage the
battery, the charge controller can control the voltage and once fully charge the
battery will make it stop to prevent battery failure. The excess power will go to
the loads. Then from here, it will be transfer to inverter and invert into AC to
provide the electricity for household items. When the sun goes down and no more
sunlight is provided, so your battery will continue to supply electricity to the
electrical items. It depends the battery capacity, the more you have the longer
you last, until tomorrow also can, no problem at all. If no sunlight for the whole
day, they won’t be any issues too because the battery will be always asked for
300% on it. They stored the solar energy into the battery until fully charged to
300%-500%.
