I had good sun today and got to test both panels and the controller again. I also tested the 25 ft extension I bought so the panels would be easier to dodge the shade with.
I saw 15a in bulk with the Schott 230w and 12a with the CanadianSolar 220w. The difference in amps between Mono and Poly is more than the 10w suggest. I think the patio was helping a bit with reflection because the numbers dropped in the grass to 13.5 and 11.79 at noon.
I did lay the 230w flat in the yard to see and got 8.8a. Both panels flat would probably be enough.
I'm sure there are more test I could run but as it is I am happy I got the Eco-Worthy 20a MPPT controller. It is a inexpensive simple solution and should it prove durable I think it may become popular. A portable set up like mine could be had for under $500 with panel prices like they are and not much more to mount it.
I'll take and post a few pics in a bit. Thanks for the comments and suggestions.
