Workig of PV Cell, used in Solar Panels.
Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.
An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity.
An inverter can convert the power to alternating cur- rent (AC).

7. ENVIRONMENTAL ASPECTS
▶ No CO2 emissions in use – 1kWp of solar cells displaces 1000 kg of CO2.
▶ No moving parts – requiring minimal maintenance and predicted life spans of 15-20
years, comparable with that of fossil fuel plants.
▶ Operation is virtually silent – unless very large transformers are required.
▶ Generation is at point of use, thus avoiding transmission and distribution costs.
▶ Cost effective in remote locations where grid connection is to expensive.
9. CONCLUSION
▶ One of the most feasible renewable energy’s for electricity generation
▶ Further Research and Development is required to capture cost-reductions
▶ Can displace power generated from fossil fuels; it is this benefit that could lead to its
future success
