The pictures depict the solar panel structure and its use for heating air and heating water.
Overall, the structure of the photovoltaic energy system is quite simple, with a box that has two holes for heating air purposes, whereas the structure for heating water includes a water pipe.
In greater detail, the general structure consists of a box with a transparent top and two holes, one for the inlet and one for the outlet.
In terms of the heating air method, cool air is penetrated through the inlet before being heated by the sun’s rays, or heat energy. This is because the transparent lid plays a vital role in collecting the energy, then heats the air inside the box. Finally, the warm air is collected through the outlet, ready to be used.
Similarly, the raw product for heating water underwent the inlet. However, the water then went through a water pipe, which is heated by the sun’s rays, contributing to the final product – warm water – coming out of the outlet.
