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.

Solar panels An array of solar panels convert sunlight to electricity. Professor of Engineering, Pennsylvania State University. Encyclopaedia Britannica's editors oversee subject areas in which they have. A solar panel is a device that converts sunlight into electricity by using multiple solar modules that consists of photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Why Go Solar? Millions of Americans are deciding to power their homes with solar energy—especially as costs have decreased—but an investment in solar energy generates more than just. Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use. There are several ways to turn. Well, one answer lies in the vast applications of solar energy.
