If anyone wants a cheap option, buy used panels from ebay or someone that people know very well like SanTan solar out of either TX or AZ I forget which state they are based in, but down south. Most of the time the panels are still within 80-90% of spec and when buying it states the spec and you can easily get a pallet 10-20units of 200-450watt for well under $300-800 not counting shipping which will vary greatly on your location but still well cheaper than buying new.

This. I purchased a lot of panels from a localish seller of used residential panels for about $0.07/watt ($20/ea for ~300-350W panels, 7 years old, 90% capacity). Though it depends on your needs-- smaller panels are good for portability and power stations, but if you're considering buying a 6 pack of these 100W panels my assumption is you're looking for raw power, and if so there are often better options.
A 100AH+ lifepo4 battery or bank connected to a powerful inverter (2000W) would power your air fryer, and these panels would charge the batteries. 600W is enough to power a small RV continuously.

Who and where is your localish seller? I am in SoCal and want to jump into solar DIY without having to spend a fortune. Do you mind sharing?

But also be advised you can't apply for the solar credit if buying used.

When you are saving over 80% off the MSRP its not a big deal.
It's not just MSRP that's a factor here.
These are bifacial panels, so efficiency per square foot is also going to be way higher than anything you'll find that's even a few years old, let alone as old as these used panels you're peddling.
These panels are on average 10% more efficient than single sided new panels of similar class. Add the loss from your used panel and that's a 20% improvement for the same amount of space required at slightly less weight.
If you have acres to mess around with, by all means, get used panels.
If you're not looking to mess around or have space/weight constraints, do not leave performance on the table.

I picked mine up near Modesto CA from a seller I found on Facebook, he had thousands of panels for $20 ea, which admittedly was a great deal. UL listed since they came from residential use. I'm using them off grid on a lot of land, so space isn't a concern for me. If you're in Northern California there's many options for used 300-500W panels in the sub $50/panel range.
Edit: The person's comment above makes a good point, that if space is a premium buying used panels might not be best for you, since they've lost 10-20% of their capacity. However, bifacial doesn't help that much, maybe 10% more power, which at that point just buy a normal panel with 10% more capacity for almost certainly more than 10% cheaper.

Bifacial only really work well if you build them on raised mounts with reflective surfaces if you just put them straight up on a roof your getting almost no benefit.

Regardless, they aren't any more expensive than singular facing panels and are more efficient than what was out 7 years ago.
You also have to factor in the lifespan of a used panel over buying new. And that's where it becomes a hobby that most people don't have time for.

False, Bifacial on average are minimum 10% more and can easily be up to 20% more in cost because they require more material.
As for lifespan most panels are good for around 25 years on average, but can go as long as 30 years. ( Panels from commercial resellers could have little to no use because of out of the box defects at commercial install sites, or taken down from commercial buildings after ownership changes.)
When it comes to cost, there is no way a used is not a good deal you save HUGE (as mentioned around 80% sometimes) and even after all the tax credit blah blah your still saving on average 50% but yeah you might have to replace the panel in 10 years boohoo... Thats only if space is really a premium and you want to replace with higher efficiency at that point.
Dude your not winning the new vs used battle in this one because of how cheap these panels are sold and can be purchased in large quantities. Only reason you need new is if your not DIY because most solar installer like to sell a whole system so they wont work with used or panels purchased somewhere else for warranty reasons of their install.
