ABSTRACT:
An electronic module compares the output voltage of a solar panel to an expected value and controls the power demand from the solar panel such that the output voltage does not vary from the expected value by more than a predetermined value. The predetermined value may be determined by correcting a room temperature value for the temperature dependence of the photodiodes comprising the solar panel and manufacturing tolerance.
