Solar Panels. Solar panels are the most recognizable part of any solar energy system. They are also called photovoltaic (PV) panels because they use the photovoltaic effect to convert energy from sunlight into usable electricity. There are three main types of solar panels: monocrystalline, polycrystalline (or multi-crystalline), and thin-film.
