Solar energy is best with efficient components. If you buy better quality components like panels and an MTTP controller you need less panels.
Buying older used panels is a total **** shoot. Most of them are less efficient designs at the end of their service lives making them even less efficient.
It is situational for that and whether you can tell what the situation really is.
In general, ISTR that new panels lose about 10% of their wattage in their first year, and then it is a slow decline after that. So there could be good deals on used panels, but not for sure every deal is a good one.
