Solar collect water heating system for commercial users

This kind of system is the extended system of the domestic systems, but different to domestic systems, but the working principle is same.

First , commercial systems are used for big capacity users, such as for hotel warm water supplying system, for hospital, for one school, factory, even the swimming pool, they all need huge capacity hot water.

Second: the system is much more complex and more hard work than the domestic system, according to the capacity, the system will need much more qty of solar collectors, maybe 100sets, maybe 200sets or more, also the water tanks are great bigger than the domestic tank ( normall such water tanks are all non-pressure water tanks).

Third: the function of the controller system is much more bigger than the domestic controllers.

Also for such commercial system, it need very big area to install so many sets of the solar collectors, the complete system need serious installing condition, also all done by specialized technical persons who have working certificates.
