    FAQs about Solar Panels and Charge Controllers

    Why do solar panels have a charge controller?

    Solar panels are designed to give a higher voltage than the final charging voltage of the batteries. They ensure that the solar panels can always charge the battery, even when the temperature of the battery cells is high, and the generated voltage decreases. Charge controllers perform the following functions:

    How to choose a solar charge controller?

    More importantly, your solar charge controller must be able to handle the maximum voltage that the solar panels / solar array can produce. This is the controller's maximum input voltage. To calculate the maximum input voltage, you need to work out the maximum output of the solar array.
