Photovoltaic Basics (Part 1): Know Your PV Panels for Maximum ...
The photovoltaic panel converts into electricity the energy of the solar radiation impinging on its surface, thanks to the energy it possesses, which is directly proportional to frequency and inversely to wavelength: this means that the energy of infrared is less than that of ultraviolet for the same amount of irradiation. In a photovoltaic panel, electrical energy is …
