To understand efficiency of a solar panel, you must first understand its source of energy – the Sun. Sun emits energy in a form of light which is composed of photons. Each photon has different energy and wavelength range (from ultraviolet to infrared). Photons are used by photovoltaic cells in solar panels to convert.
