Active Solar Energy. Active solar energy technologies convert the energy of the sun into usable light and heat. An active solar system has the capacity to store energy for later use by storing it in batteries. An active solar energy system uses electrical or mechanical equipment or processes to increase the usable heat in a system.
Mainly, Solar energy can be used to convert it into heat energy or it can be converted into electricity. Solar energy can be converted into electricity by means of solar thermal energy and photovoltaic. Through Solar Photovoltaic (SPV) cells, solar radiation gets converted into DC electricity directly. This form of energy can be used to power solar watches, calculators or traffic signals.
