The document summarizes a 100Kw solar power plant installed on the terrace of the 38th block at LPU campus. The plant uses 400 solar panels that were installed in 2013 over 3 months with an investment of 1 crore rupees receiving 30% subsidy. It generates 600V of DC current without using batteries. The panels convert sunlight to electricity through the photovoltaic effect in the solar cells made of silicon crystals with positive and negative layers.

4. INTRODUCTION
Solar Power Plant in LPU has been placed on the terrace of
the 38th Block.
400’s of Solar panels has been placed to generate
electricity in a efficient way
Solar energy i.e. Energy provided from sun is steady
throughout the year
It is the one of the most widely used renewable
energy source . It is not only benefits individual
owners, but also benefits the environment.

5. It was built in 2013 and
was constructed In 3 months.
Low cost running.
It generates 600V of
DC current.
Power of 100Kw (0.1
MW) is generated.
Amount of 1 Crore was invested in
this project and we are getting 30%
subsidy from Punjab Govt.

6. We are not using any battery
since it increases 50% of
project cost.
The length of the DC wire should be less
. Hence the grid tie inverters should not
be placed far from the panels.
Clamps are used to fix the
panels with the stands.
Some devices like lightning arresters
, temperature and radiation sensors
are used.

8. Types Of Solar Power Plant
Photovoltaic Solar plant work like this:-
Photovoltaic Electricity:- This method uses photovoltaic cells
that absorb the direct sunlight just like the solar cells you
see on some calculators.

9. How It Works ??
As light hits the solar panels , the
solar radiation is converted into
direct current electricity (DC).
The direct current flows from the panels
and is converted into alternating current
(AC) used by local electric utilities.
Finally , the electricity travels through
transformers, and the voltage is boosted for
delivery onto the transmission lines for local
electric utilities.

11. Solar Photovoltaic (PV) panels are based on a high-tech
but remarkably Simple technology that converts
sunlight directly to electricity.
The Most important components of a PV cell are
two layers of semiconductor material commonly
composed of silicon crystals.

13.  The bottom layer of the PV cell is usually doped with
boron , which bonds with silicon to facilitate a positive
charge(P) , while the top layer is doped with phosphorus
, which bonds with the silicon to facilitate a Negative
charge(N).
 The surface between the resulting “P type” and
“N type” semi-conductors is called the P-N
Junction. Electron movement produces an
electric field that allow electrons to flow from
the P-type layer to n-type layer.

16. Natural Effect OF Solar Plant
 Solar energy has the potential to dramatically
change the way the world
gets its power.
 While Solar is among the world’s cleanest forms of
energy , plans to develop utility scale solar farms
have raised concerns about potential environmental
impacts.

17. ADVANTAGES
