I'm on a search for some late '70's-early '80's Arco Solar Panels. The 16-2000 or M-51 model featured the "round" solar cell, in 32-33 staggered cell formation. I’m looking for completely intact panels, ideally still functional. Looking for panels with white backgrounds or just slightly bronzed. I’m will to purchase the panels and pay shipping. Call or text Mitch at 919-482-9269. Thanks!
