The diagrams show the structure of solar panel and its use. Write a report for a university, lecturer describing the information shown below. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The charts illustrate the characteristics of solar panels and two possible uses.

Firstly

, the basic structure of a solar

panel

is shown,

then

how the warming process of

air

or

water

works. 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

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

that is

the part through which sun rays will pass. Under the image describing the physical feats, some functions are explained.

In particular

, the first possible use of a solar

panel

is to generate warm

air

.

This

function is possible by letting

air

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

thus

creating warmer

air

that will be let flow from the outlet.

On the other hand

, 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

, 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. In conclusion, it can be stated that

this

simple model can explain the basic principles of a solar

panel

, even if is not an accurate representation.
