    1. Detailed information

    Working Principle

    The flat plate collector absorbs solar energy and the heat is transferred to water tank through pump circulation; When the temperature difference between collector and tank reaches the set value, the controller starts the circulation pump automatically for heat exchange;

    Usually an internal coil is pre-installed in storage tank as heat exchanger, a heat-transfer liquid circulates through flat panel to tank coil for heat exchange between the closed loop and main tank water, and an additional tank coil could be used to form a closed circulation loop for room or floor or pool heating.

    There are many different configurations possible; the choice of design will depend on the purpose of the system, climate, space limitations and many other factors.
