Innovation is Power

However the disadvantage of this system is that it requires additional expenses for fan operation. Photovoltaic cells which convert sunlight into electricity. How Solar Energy Is Harnessed Infographic Tapping The Sun S Energy The density of water is much higher that of air so the kinetic energy that it can impart is also higher. How is solar energy harnessed . A solar cell converts these photons into a flow of electrons to create an electric current. The system thus absorbs as much sunlight and emits as little heat as possible. Solar power Solar energy radiation from the Sun capable of producing heat causing chemical reactions or generating electricity. Sunlight essentially contains zillions of photons that have energy. The suns rays pass through a transparent surface heat the plate and then transfer heat to the room with a stream of air. People can harness the suns energy in a few different ways. In both the cases the heat in the sunlight is absorbed by the water
