What causes low power output in solar panels?

The most common cause of low power output in solar panels is obstructions or shadows on the array. Checking Voc (voltage open circuit) and Isc (current short circuit) measurements can help diagnose panel issues. Loose connectors and improperly seated terminals can cause low voltage or current output.

Why does current not flow from a solar panel to a battery?

For current to flow there should be a difference between the source and the destination voltage. Current flows from high voltage to low voltage. For example, if a solar panel has a voltage of 5.5V and a battery is 12V, current will not flow from the solar panel to the battery. The problem can also be caused by a faulty charge controller.
