Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. Below, you can find resources and information on the. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines. Solar. . Solar cell When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. They are composed of numerous solar cells made of semiconductor materials, typically silicon, which capture solar energy and convert it into usable electricity.
