The diagram below shows how solar panels can be used to provide heat energy for domestic use.
The diagram illustrates the construction as well as the functioning of a solar panel to generate energy for the domestic purposes.
The structure consists of a box with an inlet and an outlet for the things. The transparent top is used to trap the heat within the system which rises up the temperature of the item kept inside.
This solar panel can be used to heat water as well as air . In the former one, cold air is made to enter from the inlet and the falling sunrays on the transparent top get trapped in the box. These radiations further enable to collect hot air from the outlet(present at the opposite corner of the box).
The process is almost similar for heating water too. As for the water there is a need to place water pipe for its flow. The radiations so collected, would now heat the pipe inside the box and eventually the water flowing through this pipe gets heated and can be obtained from the outlet.
Overall, the working of the solar panel is simple and it does not cause any damage to environment.
