how solar panels can be used to provide electricity for domestic 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 given graph illustrates the process of producing electricity with solar panels for heating

air

and

water

. Each of these processes consists of three stages.

To begin

with, the solar panel is constructed from a

box

and a transparent top. If the electricity produced will be used to

heat

air

the solar panel will not have a

water

pipe inside.

First

of all, cool

air

is absorbed into the

box

with sun rays in it via the inlet. The

heat

energy from the sun is used to warm the

air

, which comes out from the

box

via an outlet. Turning to another domestic purpose of electricity,to

heat

water

, the process has some differences.

Firstly

, cool

water

is absorbed by an inlet into the

box

with a

water

pipe in it,where it is heated by the

heat

energy of the Sun.

Then

it comes out from the

box

through the outlet and goes into the warm

water

system of the house.
