Solar energy is energy from the Sun in the form of radiated heat and light. It drives the climate and weather and supports life on Earth. Energy from the sun has many features like global distribution, pollution free nature and present in plenty.
Earth continuously receives 174 PetaWatts (PW) of incoming Solar radiation (insolation) at the upper atmosphere. When it meets the atmosphere, 6% of the insolation is reflected and 16% is absorbed. Average atmospheric conditions (clouds, dust, and pollutants) further reduce insolation traveling through the atmosphere by 20% due to reflection and 3% via absorption. The atmospheric conditions not only reduce the quantity of energy reaching the earth's surface, but also diffuse approximately 20% of the incoming light and filter portions of its spectrum. The remaining is still a vast amount of energy that is available to be harnessed and put to work. |

| Solar power is a synonym of Solar energy or refers specifically to the conversion of sunlight into electricity by photovoltaics, concentrating Solar thermal devices or various experimental technologies. Solar power generally describes technologies that convert sunlight into electricity and in some cases thermal or mechanical power. |
