The diagrams show the structure of solar panel and its use.
The diagram illustrates not only the different features of the solar
panel
but
also
how it operates.
It is clear that
the solar
panel
has a simple structure with only a few components.
Besides
, it is run by using the power from the sun in order to heat water or air. As can be seen, the solar
panel
is formed simply in a rectangular shape with the entrance of the inlet and outlet on either side of it.
Moreover
, the top of it is covered by transparent glass which attracts sunlight for working. Regarding the operation, in the first picture, as the air is delivered into the
panel
via an inlet pipe, sun rays are absorbed in order to heat it to produce warm air. After that, it is released through the outlet pipe. In the second image, water is transported into the
panel
in a zig-zag-shaped pipe, and the power from the sunlight is used to warm up the water as well.
