Solar modules deployed in France in 1992 still provide 75.9% of original output power
New testing conducted at France's oldest PV system have shown that its solar modules can still provide performance values in line with what the manufacturers promised.

The weird thing is that in this scenario these panels are still applicable for replacement probably because the the solar panels of today compared to then are about ~40% more efficient. So compared to a new replacement it's at around 60% efficiency. A major site plans profit off of 30 years and plans to replace glass at that time, so while it may still be somewhat useful long term it's probably more profitable to replace them.
... And since they're still good they can be resold and used by others where efficiency isn't the main concern, no need to trash them
I want to add they aren't even that inefficient for 20 year old tech thats impressive
I'm sorry to tell you that the nineties were a little longer ago than that!
You mean I shouldn't wear my baggy pants with a chain for my wallet anymore?
I wonder if this type of economic calculus would mean a supply of inexpensive, second-hand panels might be available in the next few years.
They already are, at least for the smaller ones. You can go to your citie's parks and recreation department to get some. All those solar panels that power various signs and lights have been collected and replaced for years. I picked up a few years ago in Lexington, KY, for next to nothing, and they worked just fine for the lights that I wanted to power, despite only outputting less than 50% of their original power.
Not sure where you would find the full size ones like these pictured.
