Thermal solar panel
A thermal solar panel is a device that collectsenergy from sunlight and transforms it into heat, transmitted using heat transfer fluid such as water (which is most common for panels sold on the market, with added antifreeze) or air.
Description of a thermal solar panel
The fluid circulates through a black painted coil eventually glass covered and protected on the other sides by insulation. The tube in which the fluid circulates can also be doubled for additional insulation.
Uses of thermal solar panels
Thermal panels using water can be used to produce domestic hot water or as additional heating.
