Description:
Flat plate solar collector is a device that absorbs solar energy from the sun and converts it into usable heat energy, the heat is normally absorbed by water in the loop, or a freeze-resistant water mixture, a kind of medium used to supplement hot water heating or house air heating.
1. Suitable for domestic, dormitories, parks, hotels, schools, public showers, swimming pools, restaurants and other sites requiring for large hot water use
2. The panel is of high efficiency and good performance
3. Suitable for open or closed Loop (glycol-water)
4. Suggest this type of solar collector for warm areas, for extremely cold
5.mounted on different building structure
Working Principle
The selective coating on the inner cover of the evacuated tubes converts solar energy into heat energy and water in evacuated tubes the heat. When temperature rises along with density drops, and weight goes down, hot water will go up to exchange with cold water in tank. In this way, the temperature of the water in tank goes up.
