These large panels are designed for use with building roofs and ground mount arrays. Not the roof of a van or RV. If you plan to build a large, stationary offgrid system for cheap, you have come to the right place. The panels below are dirt cheap and will work well for decades.
When you buy large panels, a big factor is the cost for shipping. You are always better off buying as many panels as possible. Try to find a friend who also needs them so you can do a group buy. If you buy individual panels, the shipping can double the cost of your system!

If you need to buy a lot of solar panels for a large system, you will need a pallet deal. Buying individual solar panels does not make sense with how much they cost to ship. The more you buy, the cheaper they get.

I tested a stack of N-type solar panels and the best bang for your buck was the callsun. I was pulling the same numbers as the most expensive renogy panel! Most N-type solar panels have a low quality back sheet and rails. Not the callsun. I ordered it randonly for another video and I could not believe how well they worked. And they are nearly the same price as a traditional panel

Reliable used solar panels at the lowest possible price.
Santan Solar sells used but inspected solar panels from Arizona. Every panel they sell is a high-quality name brand solar panel, and after selling 1000’s of solar panels they have only had a handful of returns.
These are a fraction of the cost of the solar panels I recommend above, and will work for a long time.
The big downside with these used solar panels is that you need a larger mounting structure because the output is lower. This can increase costs. Santan also sells higher output panels, but they do cost more.
If you have a limited roof space, stick with higher output, brand new panels. If you have a ton of space and can mount them yourself, used panels are a fantastic option.
The problem with santan solar is that the shipping cost is pretty steep. So be sure to use this option if you plan to build a large array only.
