Parallel sounds like a good plan for you. My results are favorable to serial as I've posted with 3 different shade conditions. One of the telling aspects of my postings is the panel voltage and controller output voltage/amps/watts. Clearly the panel voltage reflects the bypass diode operation. Perhaps this summer I'll park in locations that will provide more interesting observations.
So I'm wondering: Do all 3 of your panels have blocking diodes and are they working? Are they the 3 mismatched panels as you posted in another thread?
