Discussion of solar photovoltaic systems, modules, the solar energy business, solar power production, utility-scale, commercial rooftop, residential, off-grid systems and more. Solar photovoltaic technology is one of the great developments of the modern age. Improvements to design and cost reductions continue to take place. How efficient will it become? When will it become so affordable that it's accessible to everyone? How are other energy industries having an effect on solar pv?
It seems like the local market is being flooded with used panels that are only a couple years old, most less than 5 years old, poly, and 200W+. These panels are averaging $75-100 with most of the popular brands like Trina and Kyocera going pretty damn quick... BUT, one thing I've found interesting is Sharp panels aren't selling at all, and as such, prices are as low as $60 for a 216W panel...
Is there a reason the Sharp panels are so cheap?
Is there a reason all the used commercial panels I'm seeing are poly instead of mono?
Having 800+ watts of solar for less than $250 seems insane, but I'm feeling like there's a catch somewhere....
So, what should I be looking out for?

I have all cheap used panels. They work great. If it’s diy go for it. Just get more panels than u need to compensate for lower efficiency. But.they are so cheap no big deal. Seeing Trina @ $100 for 290w now
I paid $90 for a 340 watt panel off Craigslist. It has a scratch across the glass, but works great.

I've notice this too. Been wondering if I should risk the $2-300 for 4-600 watts for my shed.
Look for new panels…
Of course! Why didn't I think of that?! I mean, hey, everyone has a grand laying around to buy 4 brand new 200W solar panels, and would never want to look into slightly used panels for 75% off the price of new...
I get what you are saying but I feel like used panels are just a headache waiting to happen. If you feel like there’s a catch, there’s probably a catch.
Be aware of possible microcracking ... very hard to detect. Also be sure to understand what the original mfr’s. warranty said ... and determine if the company is still in business. Many have gone under.
It will be in a mobile install, which isn't a nice environment to begin with. I'm guessing I'd find out pretty quick.
I'm assuming microcracking will present as decreased or seemingly random output, especially varying with temperatures?
Reduced performance
Are you able to claim the Federal Solar Tax Credit if you buy used solar panels and install yourself? (Can't seem to find a clear answer anywhere)
Not sure if you found your answer but unfortunately, no, you can't claim the tax credit on used equipment.
What does microcracking look like? Can it be repaired?
