The diagrams show the structure of solar panel and its use.

The chart illustrates the diagram of solar panels, which are used to convert sun energy to heat

air

and

water

. As a structure, the solar panel is a square, flattened case with two pipes attached on two sides opposite to each other. These pipes are an inlet, to pass

air

or

water

in and an outlet,

on the contrary

, to deliver heated sources to consumers.

Above all

, the squared construction is covered with a transparent plate through which sunlight passes through. The device which is to be used to heat

air

functions are
