Abstract

A solar photovoltaic (PV) water heating system includes a tank () including at least a first heating unit () having at least first and second heating elements (), at least one of which is switchable (A . . .); a PV solar collector (); an inverter () adapted to convert the output from the PV collector to an alternating power supply; a modulator () to modulate the alternating power supply from the inverter; a controller () adapted to control the modulator and the switching of the or each switchable heating element; wherein the controller is adapted to control the modulator and the switchable heating elements to maximize the energy drawn from the PC collector.
