Someone near me is selling all these panels for 2500 bucks OBO. She knows nothing about them, they where there when she bought the property. Do yall think they are worth looking at? If so what should I look for? I can test voltage and look for cracks. I think I count over 46 panels total. If so that is less than 55 bucks a panel. She does not have any batteries, or inverters. Only the panels.
