There are two main types of solar energy technologies—photovoltaics (PV) and concentrating solar-thermal power (CSP). You're likely most familiar with PV, which is utilized in solar panels. When the sun shines onto a solar panel, energy from the sunlight is. . These advances are making solar technology more powerful, affordable, and versatile, accelerating the adoption of solar energy technology across residential, commercial, and utility-scale projects. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy. Professor of Engineering, Pennsylvania State University. Encyclopaedia Britannica's editors oversee subject areas in which they have. .
