Used solar panels...good deal?

[kingranch]

Found a set of used solar panels looks like they were on a house or roof at some point. They are 30$ each and about 15 of them.
sharp panels..and they retail like 900$ each new. Are they outdated? Maybe could use on off grid camper build?

How many watts are they now producing. There is a declining return vs. life of panels from what I’ve experienced.

My first thought was, Why were they taken down?

OP, I can't answer your question but I can offer a comparison. I'm not claiming this company is anywhere near the quality or capable of handling whatever you're planning, but a 195 watt panels brand new from them is $159. I have two of their 195's at my cabin on the island across West Matagorda Bay and they've been powering things well over a year (probably more like 2) without any issues so far. I've seen the two panels put out 340 watts together which I was happy with for my purposes considering all the normal losses and such.

175 watt I believe
I think I could voltage test them all in sunlight to be sure they are good

Seems like a good setup for a small cabin or wellhouse for cheap... just need to source a good battery bank and maybe an inverter

I'd say you got a great deal.
