Hey Solar Gang!
I'm a total newbie here and have been inspired by Will's videos to start putting together my own DIY solar system for my home.
I'm working with a tight budget, so I figure I could save some money by buying used solar panels on craigslist. I found a guy willing to sell 210w panels for $50ea., which seemed like a decent deal to me. I went to go test one of the panels and the voltage reading was higher than the sticker on the back, and the amp reading was lower. I've attached a photo of sticker.
My multimeter read 31.8volts & 5 amps...ultimately 159w, which is nearly 80% efficiency vs the 210w rating, which seems good I think.
Is there something wrong with the panel reading a lower amperage and higher voltage than the sticker, or do you think its a safe buy? Also do you think $50/panel is a good deal?
Thanks in advance for your insights!
