Solar Photovoltaic (PV) String Calculator

Many folks have asked us how to wire their solar panels, and what size charge controller to use. Morningstar has just released a new array calculator to help determine how to wire the PV array, and what size controller to use with it. It includes technical info on a wide variety of commonly used solar panels. If you have questions on how to use the calculator, suggested wire sizes, or for a quote on a particular charge controller, drop us a line at sspence@green-trust.org
