Solar water heaters -- also called solar domestic hot water systems -- can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use -- sunshine -- is free.
How They Work
Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: Active, which have circulating pumps and controls, and passive, which don't.
Active Solar Water Heating Systems
Evacuated-tube solar collectors
They feature parallel rows of transparent glass tubes. Each tube contains a glass outer tube and metal absorber tube attached to a fin. The fin's coating absorbs solar energy but inhibits radiative heat loss. These collectors are used more frequently for U. S. Commercial applications

Solar water collector:
A. Module design, arbitrary combination, harmonize with the building perfectly
B. Intelligent control and automatic operation
C. Anti-freeze: Using the anti-freezing liquid as the medium and the controller has The anti-freezing function
D. Multifunction: Bathing, washing, domestic heating etc.
E. Work at anytime and enjoyable.
