The diagram shows the structure of the solar panel and its use.
To use solar energy we need a solar panel which collects sun rays into a box and turns cold materials into hot materials using its machanic and the laws of physics.
If we take a closer look to the structure of a solar panel, we can see that it is generally a box with a glass on the front. Additionally, it has two opennings on its sides, one located higher than the other. When the wheather is cold, cold air enters through the lower oppening. With the help of the sun rays, it turns into warm air. After the transition to warm air, it exits the panel from the higher openning.
This panel is also usefull for turning cold water into hot water. The system is mostly the same, with some minor changes. The cold water enters through the lower openning, and with the help of the sun rays coming through the glass, it gets hot. However, this time the box’s inside is not empty. It has flactuated pipes across the box, connecting the two opennings. This way, water can go through the higher openning easier.
