Principle: Solar Photovoltaics provide the power for electrically powered cooling by conventional compressor-based or adsorption/absorption-based, though the most common implementation of compressors. For small residential and small commercial cooling (less than 5 MWh/a) PV-powered cooling has been the most frequently implemented solar cooling technology. The reason for this is debated, but commonly suggested reasons include incentive structuring, lack of residential-sized equipment for other solar-cooling technologies, the advent of more efficient electrical coolers, or ease of installation compared to other solar-cooling technologies
Operation: Solar air conditioning is be done by passive solar, solar thermal energy conversion and photovoltaic panels. It has an important part in saving approximately 40 percent of residential electricity bill. PV-powered cooling is the most frequently implemented and more efficient solar cooling technology.
Application: Various methods of the following can be described as, Earth sheltering or Earth cooling tubes to reduce conventional air conditioning requirements, passive air cooling by using solar thermal energy indirectly to create a cold environment or drive any direct cooling processes. Instead, solar building design aims at slowing the rate of heat transfer into a building in the summer, and improving the removal of unwanted heat.
