Large 300W+ Solar Panels for Stationary Use only
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.
Pro Tip:
If you have a solid roof rack on the roof of a vehicle, you can mount a 200W panel safely. Solar panels larger than 250W need 6+ mounting points per panel. Anything larger than 300W can be very dangerous. It is possible, it just needs a very strong roof rack to accomplish it safely. Also be sure to use a stainless steel safety line for each panel in case one does fly off your roof.

Signature Solar: Bulk Solar Panels
(expensive shipping unless you buy a large order)
|
Keep in mind that when you purchase solar panels, the shipping cost can be extreme. Always buy solar panels (and batteries) in bulk to save money.
The panels offered by signature solar can change week by week. There is no consistency of panel available but the prices are great. If you need to buy more of the same panel in the future, I would stick with the 400W Rich solar panel above.

Used Solar Panels: Dirt Cheap!
|
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. Click Here to check them out! Click Here to buy my favorite panel they make. 250W Panel for $69! |
