Writing Task 1: (Process) 

The diagrams show the structure of solar panel and its use.

Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Model Answer

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.
