6 Frequently Asked Questions 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.

What is a charge controller?

The charge controller can be supplied as a separate device (for example, an electronic unit in a wind turbine or solar PV system) or as a microcircuit for integration into a battery or charger. Solar panels are designed to give a higher voltage than the final charging voltage of the batteries.

What is a solar power controller?

The chief function of a controller is to protect your batteries. Since batteries are the most expensive part of a solar power system, you want to protect your investment. Unlike batteries or inverters that have several types, controllers are much simpler in that you have two options to choose from. You either go MPPT or PWM.

How does a solar controller work?

If a solar array has a voltage of 17V and the battery bank has 14V, the solar controller can only use 14V reducing the amount of power. With Pulse Width Modulation controllers, as the batteries approach their full charge, current to the batteries is regulated by “pulsing” the charge (switching the power on and off).

How does a solar panel Charger work?

The solar panel connects to the controller through positive and negative leads, only creating a charging function when the controller is connected to a battery. The load is then responsible for the discharging function from the controller (if it is connected to the controller).
