The rendered diagram shows a solar panel and illustrates the working of a solar panel used to heat air and water.
A solar panel is an instrument that is used to capture direct sunlight and transform it into a useful form of energy. A solar panel consists of a box with a transparent top. It has two openings, that is, inlet and outlet. A solar panel can be used to heat air and water.
A solar panel is placed in direct sunlight, where it uses sun rays as a form of energy. The box is fed with cold air through the inlet opening. With the help of direct sunlight, the air inside the box gets warm. We can fetch out the warm air through the outlet opening of the box.
To use a solar panel as a water heater, the box is fitted with a water pipe through which the water will flow inside the box. The water enters the box through the inlet opening and goes on passing through the water pipe. The box is exposed to direct sun rays. The warm water can be taken out through the outlet opening of the box.
