The design and utility of solar panels are depicted in the illustrations.
Overall, it can be seen that the solar panel is a rectangular box with a transparent glass on the top. Next, the box consists of two pipes that represent the inlet as well as the outlet of the substances. The solar panel is used to convert sunlight into heat energy.
To begin with, this rectangular prism panel structure is uncomplicated. Specifically, the solar panel has a translucent glass on top of it to absorb the sun rays. Moreover, there are two pipes on each side of the panel called inlet and outlet.
Furthermore, the solar panel can be used to heat up air and water. To be exact, the panel first absorbs the cool air, then the air temperature rises due to the sun rays, and finally releases the warm air. Additionally, the process of heating water is roughly the same. The cold water which is let in through the pipes plus heated up by the sunlight will eventually become hot water.
