Can I Run One MPPT Solar Controller for Two 100W Solar Panels?
Question:
I am about to purchase one MPPT controller to operate two flexible panels each at 100W. I realize that one panel – one MPPT is optimum, but, in the meantime I wish to connect the two panels in parallel because of shading from my boom. Next year I get two more 100W panels and another MPPT – so that I will have two 100W panels in series per controller. Panels are rated at 5.68A. What size of controllers are best for this present plus future expansion? Is this scenario a good one? - David
Answer:
With two 100W solar panels wired in series, one MPPT controller that can handle the combined series voltage and amperage is what you need. For instance the Victron MPPT 75/15 is well suited to handle two 100W panels wired in series.
