Abstract
In order to obtain a solar power generating device capable of effectively using power generated by a solar cell, the virtual optimum operating voltage, the MPPT minimum voltage, the MPPT maximum voltage, and the low and high voltage change width switching voltages used when MPPT control is carried out are calculated on the basis of the output voltage of a solar panel immediately before the startup of the inverter circuit in the solar power generating device and the MPPT control is carried out on the basis of each of the calculated voltage values.
