Hi Will. My goal is just to off grid a couple of circuits.
I found a local source for used 335W 40x80 panels at a what may be a good deal. I'm not affiliated with the supplier and I just found them on CL. Please let me know what you think and it might be good to share with others as they have over 5000 in stock.
