“One hour of solar energy is enough to meet the energy demand of entire Earth’s population for one year.
When the solar radiation reaches earth’s top atmosphere it is relatively constant everywhere but the radiation near earth’s surface may vary considerably due to following reasons:
- – Atmospheric effects, such as absorption and scattering.
- – local variations in the atmosphere, such as water vapour, clouds, and pollution;
- – latitude of the location; and
- – the season of the year and the time of day.”
