Newly-designed flat panel 100L solar collector
Working principle
Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy. The heat is transferred to liquid passing through pipes attached to the absorber plate. Absorber plates are commonly painted with "selective coatings". Absorber plates are usually made of copper or aluminum because the metal is a good heat conductor. Copper is more expensive, but is a better conductor and less prone to corrosion than aluminum.
Features
1. Collectors are separated from the storage tank. The tank can be put anywhere of the house,so the whole system is harmonious with the building
2. Absorbing heat quickly
3. No worry about being frozen because there is no water running inside the tubes when working
4. Completely automatic operation
5. It can withstand pressure of tap water when it works
6. Without incrusting, long usage life
7. Multifunction: Bathing, washing, domestic heating
8. Beautiful appearance
