<p>A process which force a solar array to operate permanently at its maximum power point (MPP). This feature is available using a microprocessor which receives permanently the amplitudes of the operating point coordinates, the solar array voltage (Vsa) and current (Lsa) and its temperature (T). The microprocessor (PIC (1) ) computes, using these data, the MPP of the solar array, whatever are the environmental conditions and ageing, and uses the MPP voltage (Vmpp) as the reference of a series or a shunt conventional power regulator (7) to force the solar array to operate at this MPP. The MPP is computed solving one, two or three unknown equation system, depending on the type of the power regulator managing the solar array voltage and the temperature, to get the electrical characteristics i (v), defining the power characteristics P (v) and solving the equation dP/dv=O.</p> |
