The diagram illustrates the layout of a solar panel and its use in heating air and water.
In general, there are three main components in the panel. To start with, it consists of a rectangular box covered with a transparent top. An inlet is placed on the left-hand side with the outlet on the other side. Furthermore, if the panel is used for heating water, a water pipe is inserted between the inlet and outlet to let the water pass through.
The sun’s rays generate heat energy to increase the temperature of the air and water entering the box through the transparent glass. These substances are heated after absorbing the energy. When leaving the box, warm gases and liquid can be acquired.
This panel has an environmentally friendly design since it relies on the heat energy generated by the sunlight. No extra energy is needed to heat up the substances.
