I picked this panel up in 2025 for $5 as part of a solar education display that our local museum was disposing.
Its a "BP Solar" brand, which looks like they folded in 2011, so it's pretty old. Looks okay though. It's a
pretty small panel, but is weatherproof with a solid frame, and I'd guess it's rated about 30w.
It measures 21"w x 17.5"h x 1.75"d. The generic template on the back (with the hand-written model number)
suggests this was a demo or maybe a blem, sold at a discount for demonstrational purposes rather than energy
production. The "Solar Power" label on the front was probably added for the display.
I connected it to my solar tester and got the following specs: (Nov 23, 2pm)
