Solar panels absorb solar energy and convert it into heat. As the main part of a solar thermal system, they produce heat for hot water production and heating support in the home.

SunPower Solar Panels- Information and tips
Structure and function of solar panels
Thermal sunpower solar panels, represent the main component of a solar thermal system. In contrast to solar modules, which convert solar energy into electricity, the collectors produce heat or thermal energy, which can be used in domestic hot water production and heating. Thus, up to 40% of the heating and up to 70% of the domestic hot water can be supplied by solar energy. Furthermore, solar collectors are used to heat swimming pools, in solar thermal power plants for power generation and for the production of process energy in the industrial sector.
SunPower Solar Panels- Suggestions and detailed info
This is how a solar collector is constructed:
Inside the collector is the absorber, which absorbs solar radiation, heats up and transfers heat to a heat transfer medium. The heat carrier is a liquid, which usually consists of water and propylene glycol – it is also called the solar fluid. Propylene glycol is designed to prevent the water from freezing in winter and getting too hot in summer. Via pipes, the heated liquid is transported by pump through the absorber and then into the solar storage tank. This supplies the household with warm water.
So that the sunpower solar panels are protected from heat loss to the outside, the absorber is insulated laterally and below. Only in low-temperature collectors for swimming pool heating is dispensed with an insulation. Against the weather and mechanical stress such as snow, hail or wind protect the housing of the collector and a transparent glass cover. The latter also prevents the heat extraction of the absorber by cold wind but also the heat radiation from the absorber.
