And because solar Chandigarh, India [email protected] Abstract Over the years, excessive exploitation of energy resources have made a catastrophic impact on the environment giving it very less time to retrieve. Solar cells harness the energy from the sun and transform this into usable electricity. Economy-friendly energy - Solar cells provide a great opportunity to create savings on your electric bill since you do not pay for the energy that you generate. The disadvantages are that they still have cost to manufacture and install, and the energy output isnt particularly dense for the required area compared to some other ways of getting energy. Solar panels do not release CO2 into the atmosphere like fossil fuels do, and they do not involve the huge risks of nuclear power. Another big selling point for solar is that it is a renewable energy source. This means that as you use the resource, it doesnt deplete the source. So, by using the sunlight that hits the earth and turning it into electricity, we don't deplete the suns energy. A large number of solar cell are combined in an arrangement called solar cell panel Solar Cell. 11. When these panels enter landfills, valuable resources go to waste. 13.
