What is Solar?
Solar energy is the most abundant, renewable energy source in the world. Solar energy systems refer to technologies that convert the sun’s heat or light to another form of energy for use1 2
There are two categories of technologies that harness solar energy, Solar Photovoltaics and Solar Thermal.
Solar Photovoltaic (or PV) is a technology that converts sunlight into direct current electricity by using semiconductors 3. In contrast, Solar Thermal is a technology that utilizes the heat energy from the sun for heating or electricity production
Solar is a renewable resource and does not emit any greenhouse gases in the energy generation process. However, the cost of solar in relation to other fuel sources is a barrier to adoption. Additionally, sunlight varies depending on geographic location, season, and time of day, which all creates limitations on its use.
