Solar energy is a converted solar energy to electrical energy. Today mostly used for street lights .they used a panel .The panel absorbed the sun light .so the sun light ray converted to electrical energy .The solar energy is a non-payable energy. The solar light is depending on the solar grid. This piece of the light sets aside vitality from the sun oriented board and gives control when required around evening time when there is no light vitality accessible. As a rule, the productivity of photovoltaic vitality change is constrained for physical reasons. Around 24% of sun based radiation of a long wavelength isn't ingested. 33% is warm lost to environment, and further misfortunes are of roughly 15-20%. Just 23% is consumed which implies a battery is a pivotal piece of sunlight based light This area controls the whole working frameworks to ensure battery charge. It guarantees, under any conditions incorporating extraordinary climate conditions with substantial temperature contrast, the battery does not cheat or over release and harms the battery even further.
