SOLAR POWERPROJECT

CHANDRAPUR Presented by

D.L.Pawar , Dy.E.E (Projet!



Jawaharlal Nehru National Solar Mission

“ Our vision is to make India’s economic development energy-efficient. Over a period of time, we must pioneer a graduated

shift from economic activity based on fossil fuels to one based

on non-fossil fuels and from reliance on non-renewable and

depleting sources of energy to renewable sources of energy.

In this strategy, the sun occupies centre-stage, as it should,being literally the original source of all energy. We will pool our

scientific, technical and managerial talents, with sufficient

financial resources, to develop solar energy as a source of

abundant energy to power our economy and to transform thelives of our people. Our success in this endeavor will change

the face of India. It would also enable India to help change the

destinies of people around the world.

PV Technology Classification

Crystalline Technology Thin Film Technology

A) Mono Crystalline PV Cells A) Amorphous Silicon PV Cells

B) Multi Crystalline PV Cells B) Poly Crystalline PV Cells

( Non-Silicon based)



Silicon Crystalline Technology

Currently makes up 86% of PV market Very stable with module efficiencies 10-16%

Mono crystalline PV Cells

•Made using saw-cut from singlecylindrical crystal of Si

•Operating efficiency up to 15%

Multi Crystalline PV Cells

•Caste from ingot of meltedand recrystallised silicon

•Cell efficiency ~12%

•Accounts for 90% of

crystalline Si market

This diagram shows a simple parallel circuit

to increase current or power. Assume that

we are using 640 volt solar panel and 1.25A

current. The power of all 1536 panels(structures add to give us the effect

of 1536 times as powerful !ut the voltage

sta"s the same at 640 volts. #arallel wiringincreases current !ut the voltage does not

change. The output of this wiring gives us

$ 2000A and a!out 1.2% &' power.
