So someone local to me is selling REC 300 watt panels used. Would they be worth $225-$200 each? Will they work with Victron setups that seem fairly popular? Are all panels compatible?
Look up SanTan Solar, with locations in Gilbert AZ and Georgia. I don't know where "local to you" is...but you can get commercial 250W panels from them for under $75. If you can pick them up and save shipping, they're the best value out there.
