Reflective solar photovoltaic panels
Solar panel reflectivity, or the extent to which a solar panel reflects incident light, impacts PV system efficiency and energy production. Reflective solar panels are not a separate type of solar technology, but rather standard photovoltaic (PV) panels that have reflective properties due to their glass covering. In addition, the reflections can also be harmful to surrounding wildlife or heat-sensitive equipment. Improving the reflective ability of sunlight, referred to as Albedo, increases the amount of light that enters the rear side of the module, which has the effect of. Germany-based Solmax has developed a reflective membrane made of polyethylene resins and coated with a thin white polyethylene layer that reflects ultraviolet (UV) rays.
