My Favorite 100-400W Solar Panels
-Great for Mobile Solar Systems!-


Small Glass Solar Panel Crash Course:

Picture
​Pros:
  • Cheap
  • Extremely durable (can handle snow, rain, heat for years!)
  • Easy to mount
  • Last 25+ years, no problem

Cons: 
  • Heavy. Typically around 16 pounds for a 100 watt solar panel. Larger panels are lighter for their output.
  • Mounting glass panels to the roof of a moving vehicle is typically a bad idea. If one of these falls off your roof, someone can die. Make sure you mount all panels securely.
  • Requires air flow under the panel. Just an inch or so, not much, but it is necessary. 
  • Do not mount large glass panels to your roof unless you have a strong roof rack. 100 watt panels are inherently strong due to their size and are the best size to mount to the roof of a vehicle.

What About Flexible Solar Panels?
​Don't Buy them!

Every single flex panel on the market is garbage. I challenge anyone to prove me wrong on this. I have destroyed stacks of these things. The cells crack easily and take out a whole string of cells when the bus bars break. Or they have extreme degradation after a few months of summer. Even the latest "CIGS" panels that I was so excited about, are having delamination problems. 

Do yourself a favor, and avoid the flex panels. None of them are good.

Best Performance Solar Panels

For the money, the panels above are fantastic and will last a long time. If you are limited on roof space, you should buy N-type solar panels. The output for their size is incredible! If you are build a van or RV system, you should buy these. I have tested a lot of these panels this year, and these are my favorites:

I tested a stack of N-type bifacial 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:

If you have more money to spend and want the same performance as the callsun, check out the renogy shadowflux. It handles shading better than the callsun, but it comes at a price. I tell most people not to invest in "shade tolerant tech" and focus on mounting more panels in a better direction with the sun. If you have limited roofspace and you are constantly dealing with shading from large objects or leaves, the shadowflux might be worth it:​

And thats it! Most of the other panels were not performing as well or had cheap rails/backsheets/junction boxes. The panels above are my favorites out of stacks of solar panels that I tested. Stick to the ones above and you will be set. 

Dirt Cheap Solar Panels

Picture
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.


What people don't realize about solar panels, is that they last for decades, if not centuries. Most panels are rated for 25 years to 80% output, which is an extremely conservative goal. Most panels can produce well over 90% of their rated output after 30 years. They can also handle years of non-stop rain/hail/snow/wind without issue.

​For me personally, I go for the cheapest panels possible, because cost is not really a determinant factor of performance (such as the cheap solar panels I recommend above). After my real world testing of stacks of solar panels, many cheap panels can produce the same or more power than the more expensive ones, and they have the same safety ratings, and warranties.

​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.
