A solar energy system has water circulated by a pump (14) through a solar energy recovery panel (10) to a storage tank (12) filled with usable water. The heating circuit has a heat transfer coil immersed in the tank and signals are fed to a monitoring circuit (40). the temperature difference between the sensed valves is compared by the processor with a deprived threshold. This allows a range of faults to be identified. <IMAGE> |
