Yes, I’m impressed at all the used panels available, probably from all the overpriced systems that home owners can’t pay and have to repo.There is a surprising amount of solar gear on Facebook market place.
Yeah the guy I get them from says the company he got them from is tasked with taking out the "old" panels every 2 years in Califonia. Something about the State and Federal tax deductions can be reused so long as the panels are installed for at least 2 years. So that rip them out, sell them at a profit after the deductions and labor to reinstall. I'm paraphrasing but thats the just of it. It may be wastful on that end but provides the market with good used panels at a great price!Crooked installers in Australia often convince owners that the only way to upgrade is to replace everything. It can also be that systems are changed out to keep feed in tarifs. I'm not sure if it still applies but at one stage several electricity retailers here tied the feed in tarif to the specific electricity account. If the premises changed hands the feed in went away.
My own 2nd hand panels came from an installation where one panel had failed so the whole lot was replaced. Terribly wasteful but that's how it goes.
I wish solar panels would plummet in price like computer flash drive storage did...
Yup.But ON topic, just as an example, a place near me in northeast Ohio has a skid of 250w Hyundai panels for $160. I don't know a good panel from a can of tuna so I don't know if that is a good deal or not, but the point is there are people who buy them used by the skid and sell them on Craigslist. Of course if you are not in northeast Ohio, that specific example means nothing to you. But I can't believe that kind of thing isn't everywhere.
My sister sold me overpriced ram once... ONCE!
