Solar gain (also known as solar heat gain or passive solar gain) is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation. The amount of solar gain a space experiences is a function of the total incident solar irradiance and of the ability of any intervening material to transmit or resist the radiation. WebDec 1, 2013 · Akbarzadeh and Wadowski [1] designed a hybrid PV/T solar system and found that cooling the solar photovoltaic panel with water increases the solar cells output power by almost 50%.
