Patent abstract
In one method of using solar power as a supplemental power source in a DC system of a vehicle, the voltage of a vehicle battery is measured to determine if an alternator is operating. Upon determining that the alternator is running, a solar charge controller sets the voltage set-point to be about 0.1 Volts higher than the voltage produced by the alternator. This allows the solar panel to contribute up to the full power capability of the solar panel to the DC power system, even though the battery may be fully charged, which reduces the load on the alternator, thereby improving fuel economy.
