How Solar Cells Work
1. Photons in sunlight hit the
solar panel and are absorbed
by semiconducting materials,
such as silicon.
2. Electrons (negatively
charged)
are knocked loose from their
atoms, allowing them to flow
through the material to
produce electricity.
3. An array of solar cells
converts solar energy into a
usable amount of
direct current (DC)
electricity.

MANUFACTURING PROCESS
 Lay-up:- In this process, solar cells are put in between Various
layers for lamination and curing process.

 Connected Assembly Of Solar Cells.
 Output Of 0.5 - 0.6 Volt DC.
 Output Current Depends On Area Of
The Cell And The Amount Of Light
Falling.
 So Efficiency Is Determined By The
Area Of A Module.

12. Some Interesting things about Solar in
Gujarat and India also

 With about 300 clear and sunny days in a year, India's theoretically
calculated solar energy incidence on its land area alone, is about
5,000 trillion kilowatt-hours (kWh) per year (or 5 EWh/yr). The
solar energy available in a year exceeds the possible energy output
of all fossil fuel energy reserves in India. The daily average solar
power plant generation capacity over India is 0.25 kWh per m2 of
used land area, which is equivalent to about 1,500–2,000 peak
(rated) capacity operating hours in a year with the available
commercially-proven technologies.
 On 16 May 2011, India’s first 5 MW of installed capacity solar
power project was registered under the Clean Development
Mechanism. The project is in Sivagangai Village,
Sivaganga district, Tamil Nadu.
 In January 2015, the Indian government significantly expanded its
solar plans, targeting US $100 billion of investment and 100 GW of
solar capacity by 2020.

Solar power in Gujarat
 Gujarat Solar Park is the name used for a group of solar parks being
constructed in Gujarat, India. This makes Gujarat as Asia's largest
solar park hub. Certificates of completion were issued on 19 April
2012, for a total of 605 MW, which included some sections that were
already operational, and 856.81 MW had been completed by 31
March 2013. One is the Charanka Solar Park, a group of 17 thin-film
photovoltaic (PV) power systems, on a 2,000-hectare (4,900-acre)
site in the district of Patan.
 The solar park is expected to save around 8 million tonnes of carbon
dioxide from being released into the atmosphere and save around
900,000 tonnes of natural gas per year.
 A total of 84 developers have registered to build a total of
968.5 MW, from 1 to 40 MW. An increase to 1,000 MW is expected to
be completed by 2013.
