-Built Photovoltaic panels ( 24 volts ) to connect the circulation pump DC.
Principle
A glazed flat-plate solar collector consists of a shallow rectangular box with a flat black plate behind a tempered glass cover. The plate is attached to a series of parallel tubes or one serpentine tube through which water or another liquid (such as an antifreeze solution) passes. 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. Sunrain Absorber plates are commonly painted with "selective coatings".
As the liquid circulates through the system, it absorbs the heat from sunlight falling on the collectors. The heated liquid then enters a heat exchanger or is added directly to the conventional system. In commercial applications, the solar-heated water flows to a storage tank that is connected to the conventional water heating system. Although flat-plate solar collectors could mainly be used under the circumstance of the temperature above zero centigrade as they are less efficient in cold weather than in warm, the system is best suited to applications that require medium to high temperatures.

Installation
Installation for collector arrays up to 20㎡
Connect the collectors with metal pipes (e.g. metal bellows) rather than plastic pipes, given high temperature and pressure resistance there.
1)Single-rowed collectors
2)Double-rowed collectors
Note:
(1) Every row install 7 collectors at most, if the system needs more than 7 collectors, please install them in series and in parallel meanwhile.
(2) The copper pipe may expand with the high temperature, so suggest using metal bellows among three collectors to avoid the pipe being out of shape.
(3) Secondary circulation can prevent freeze effectively.
