Question

What is solar energy?

Answer 1

1. Solar energy has specially drawn attention for its practically free, steady supply and pollution-free use.
2. Solar energy can be tapped more effectively in regions where there are long sunshine hours, like India.
3. Solar energy does not add additional heat to the atmosphere, although the production of solar panels may contribute to pollution.
4. Solar panels, often mounted on roof tops, absorb and move rooftop heat into water circulating within the panels.
5. Photovoltaic (solar) cells produce energy directly from sunlight, although the cost of this energy is several times what conventional (fossil) fuel-generated electricity costs.
