The solar hot water system power supply provides both controller and pump with 21 volts DC. The pump will start when there is enough sunlight, which is measured by a sensor within the solar collector. The signal is interpreted by a microprocessor controller, which also controls the safety functions and a time delay.
Because the control operates on low voltage DC it is suitable for operating from a small PV (photovoltaic) panel (see picture below).
