Solar radiation is light – also known as electromagnetic radiation – that is emitted by the sun. While every location on Earth receives some sunlight over a year, the amount of solar radiation that reaches any one spot on the Earth’s surface varies. Solar technologies capture this radiation and turn it into useful forms of energy.
Solar radiation, the radiant energy emitted by the sun, serves as the primary source of energy for PV systems. Understanding the characteristics of solar radiation, including its intensity, spectrum, and variability, becomes paramount in optimizing the performance of photovoltaic cells.
PV cells convert solar radiation into electrical energy. The electricity generated by these modules is in the form of direct current (DC) where a DC motor-driven compressor (to drive the refrigerant) is used for the vapour compression system or it uses an inverter to convert the produced DC to AC.
Most of the solar energy is neither absorbed nor reflected back by the atmospheric layer before it is received on the earth’s surface through the amount of atmosphere called air mass (AM) which depends on the geographical site and the time of day and year.
