Introduction
Our team TEJAS represent KIIT University Bhubaneswar under the guidance of Dr. S.K.S Parashar professor School of
applied science. The team members consist of G. Usandra Babu assistant professor School of electronics engineering as
the deputy team leader.
We are a bunch of enthusiastic technocrats who are whole heartedly dedicated for the development of the untapped
solar potentials and as a whole development of India where we can make India energy efficient and we dream of that
India where each village is lighted and no child has to read in candle light the night before exam.
Executive Summary
Firstly, we are using the scenario 1 given in the brochure of Technical approach. The sunlight that
would fall on the panel will generate electricity is the open truth, we are using the principle of
reflection to collect the sunlight falling on the nearby areas to get converged on the panel and
increase the efficiency of the solar panel.
In the experiment which we performed on a 0.99X1.75 meter
sq. solar panel(230 W,32 V, 8A) we could increase around 18% Power by converging the light with
just 2 mirrors. As we know the power P = I^2R with a constant load. With this astonishing 18%
increase in the power it is a record that we have achieved. This indicates that if we use a panel worth
250 watt and this increase of 18 % in power means the power generated from the same panel is
295.5 watt which is within the tolerance range of the panel. It is calculated that with this much of
energy we could just achieve our power requirement with just 5 panels that is (5X295.5) watt= 1475
watt. Which is the average requirement of a 2BHK flat. The best part of our achievement is this is
achieved within the 7.5 sq. meter area given to us with some space left. As mentioned above the
reflector that is used as the concentrator is fitted with the reflecting surface like mirror or acrylic fiber
kind material which focuses the light on the panel in such a shape that it covers exactly the surface of
the module without any loss of reflecting light. With the change in the position of the sun during the
course of the day the direction of sunlight also changes and hence we have to change the position of
the reflector in order to save the panel from the shadow of reflector and reflect the maximum rays
during the entire time sun rays are available in the day. This movement of the reflector is done with
an Aurdino based circuit or timer circuit.
Cooling arrangement
The cooling arrangement which is required for the heat dissipation of the panel is done by a hydraulic
system connect with an intelligent timer circuit using LM 35 that will sense the temperature and if it
increases a certain temp it will start a flow of water across the panel and the moment the panel cools
down to certain point this flow stops. This heated water could be used for the different domestic
purpose.
Approach Note
Our approach for the challenge is the same as discussed in the executive summary and in the approach submission
round.
In our experiments we are using 4 panels of 230W with the reflectors to generate 1.5 kw of electricity with scenario 2
given in the approach note where the deficiency during the extreme weathers could be met by the grid supply.
The general concept of the prototype is that we are using the reflectors to direct the reflection of the sunrays on the panel
and increase he power of the panel. The diagram of the reflector and the panel is given below.
SOLAR PANEL WITH REFLECTOR
In this figure we are using 4 panels as shown above and the reflectors are such arranged that the reflection of the rays
fall just on the mirror without the loss of the reflected rays.
AREA OF THE SOLUTION
As the dimension of one panel is 1.75mX0.99m the arrangement is done in such a way that the area of the 4 panels is
6.93 sq meter. If the area of the reflector is added it comes within the 7.5 sq meter.
Hence we achieve the objective of the 7.5 sq. meter area for the entire setup.
Area of Single Panel
REFLECTOR
The reflector which we use in the solution is of the dimension 0.875m X 0.5m that covers the entire area of the panel.
The reflected rays from the panel fall just on the panel to increase the current value generated from the panel.
The movement of the reflector is so adjusted with the sun that the reflector moves with change in the position of the
sun. This movement of the reflector is done with the help of Arduino circuit using LDR devices which senses the light
and thus the position of the sun to move accordingly so that maximum reflected rays fall on the panel to generate
maximum power .

MOVEMENT OF THE REFLECTOR ACCORDING TO MOVEMENT OF THE SUN
With this kind of arrangement we had taken readings for 3 days. The data of the readings are
given and graph is plotted below.

Challenge Interpretation
We are able to make this model cost effective in comparison to the current Products available
in the market. We are able to generate sufficient amount of energy using less no of panels and
hence the cost is reduced. We have also reduced the size by making the arrange size efficient.
INSTALLATION
The installation of the solution is so designed by us that any common man can do it himself.
The installation process is simple where the consumer has to only purchase a stand which will
come with the entire solution set and place it on the roof and put the panels on it.
It is just like the air cooler where we purchase a stand and place the cooler on it. Our solution
is based on the same process where the stand will be designed according to the angle of tilt of
that particular location (which varies place to place) and as the diagram above shows the
panels kept on the stand can be done manually by any layman and these stands could be
bolted at the bottom on the roof top where it is kept.
Hence the ease of installation challenge is perfectly achieved by us here and our installation
technique can be properly explained in the diagram looking which even any illiterate man
could do it himself.
COMMERCIALISATION
Our prototype is a simple one it require some mechanical work of welding and lathe machine
with the base of the reflector fitted with the stand as shown in the diagram, only the panels
are kept and fitted on the top of the stand later.
This could be easily done in a place and the cost of the setup would decrease by approximately
2 folds when this kind of the stand for our solution comes into market.
For the prototype development we would arrange our fund from our college the college would
help us to develop the model in every possible ways , with the expertise of the staff and
faculties of our university we would easily be able to achieve it.
We even have the workshops and the laboratories of the university where we could work and
develop the model.
Once this product or prototype comes into picture we believe it would make a thrill in the
market as the challenge thrown to us were challenging and we successfully meeting the
requirements approximately in each department certainly gives us bonus in front of others.
