Learn MoreIn simple terms, a solar collector is a device that captures incoming solar radiation. The collected solar energy can be converted into either heat energy for the working fluid, as in concentrated solar power technology, or electrical energy, as in photovoltaic technology .
Solar thermal collectors work based on the principle of absorbing solar energy. Although there are different types of solar collectors, as we will see later, the operating principle is similar in all of them. First, solar radiation strikes an absorbing surface which converts radiant energy into thermal energy.
Collectors are the starting point for the conversion of sunlight into energy. They must be designed to efficiently concentrate light while minimizing fabrication, installation, and operating costs. Collectors that can cost-effectively achieve high concentrations of sunlight are able to directly improve the efficiency of the receiver.
Although concentrating collectors have different characteristics and applications compared to flat plate and evacuated tube collectors, they are still a form of solar thermal collectors as they all have the common objective of converting solar energy into heat.
In a flat solar collector, the absorber plate is exposed to the sun and is heated by absorbing solar radiation. The heat transfer fluid, which circulates through tubes on the back of the plate, absorbs the heat from the plate. The hot fluid is transported to the storage system so that it can be used when required to heat water or air.
Hybrid collectors combine solar photovoltaic and thermal technologies, allowing for the simultaneous generation of electricity and heat. These systems are designed to improve the overall efficiency of solar energy collection by harnessing both types of energy. General characteristics
