280W 300W Monocrystalline Solar Panel

280W 300W Monocrystalline Solar Panel

Chengyu Power high efficiency 280W-300W monocrystalline solar panel is designed to absorb the sun's rays as a source of energy for generating electricity.They are also known as PV or photovoltaic modules as they don't need anything beyond sunlight to produce electricity.

Product Details

280W 300W Monocrystalline Solar Panel have been the go-to choice for many years. They are among the oldest, most efficient and most dependable ways to produce electricity from the sun. Each module is made from a single silicon crystal, and is more efficient, though more expensive, than the newer and cheaper polycrystalline and thin-film PV panel technologies.  You can typically recognize them by their color which is typically black or iridescent blue.

280W 300W Monocrystalline Solar Panel can produce current  in a certain intensity ofillumination, the electrical appliance can be used. The premise is the unit of current time than electrical consumption. In practical application, the direct use of the situation is less. Generally the whole system to use.
