This online software does it all. Put in your panels, your location, your dreams and aspirations. Very cool.

Morningstar has nice solar panel string calculator

• Input your panel voltage/amp output
• Your charge controller values

Nah, you don’t have to pick their equipment. you can put in your own or even made up values. Even pick equipment with the same values as what you’re looking at.

By the way. Morningstar controllers get the two big wings up from me. Good stuff.
