What is the principle of solar renewable energy

How does solar power work? | Solar energy explained

Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to ''solar farms'' stretching over acres of rural land. Is solar power a clean energy source?

The role of renewable energy in the global energy transformation

Up to 20% of the energy intensity improvements can be attributed to the increased use of renewable energy (Fig. 5). Hydro, solar PV and wind power are generated with 100% efficiency. When these renewables replace fossil fuel power generation with 25–60% efficiency, the efficiency improves. Also net efficiency gains are created through solar heating
