Solar energy is a radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy including solar water heating, and solar desalination. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. The large magnitude of solar energy available makes it a highly appealing source of electricity.

A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The energy collected by solar panels can be used for various purposes and some of them are to produce hot water and battery storage solar lighting system. Solar Water Heating (SWH) system is used to generate hot water by sunlight, using a solar thermal collector. By the photovoltaic effect, the solar energy is collected during day hours and transforms it into electrical energy and stored in the battery for lighting system during night hours.
