Solar charge controller: PWM vs. MPPT | Solar Lights
The PWM controller, on the other hand, would be unable to catch the excess voltage as the battery charges at the same voltage as the pulse width modulation technology. However, when these panels are put into places with warmer temperature, their Vmp will decrease, and the peak power point will operate at a voltage closer to that of a 12V battery.
