of solar panels and two possible uses.

Firstly

, the basic structure of a solar panel is shown and explains the basic principles of it. Regarding the structure, it can be seen that a solar panel is formed by approximately a box, which has an inlet on one side and an outlet on the other side.

This

Linking Words

box has on it a transparent glass, that seals it and

that is

Linking Words

the part which sun rays will pass. Under the image, functions are explained.

In particular

Linking Words

, the first possible use of a solar panel is to generate warm air.

This

Linking Words

function is possible by letting air enter the box from the inlet and once is in, letting it heat up to the sun rays that get refracted by the glass,

thus

Linking Words

creating warmer air that will be let flow from the outlet.

On the other hand

Linking Words

, an additional step is required to heat up water. More specifically, a tube that connects the inlet and the outlet is needed to let the water flow through it. Given

this

Linking Words

, the principle is the same, with solar energy heating up the water inside the tube, which will enter from one side and exit from the other.
