Why solar is pretty much useless...

Unless you camp in the desert.

Interesting video, with a surprising outcome.

( alternate title.. How shading actually kills your output)

I don't camp in the desert but my solar set up is the best mod I've done. I haven't had to even think about my batteries since I installed it! By 10 or 11am they are charged up. We've stayed in it about 90 days so far this year, so it is being used.
The downside: I now have to exercise my generator!

I guess you never watched there other videos when they had there RV. They had a setup that could run there AC for a short time. To say solar is useless just means you have never had a setup that uses it. We camp in trees and that is why my solar is on a tether so I can move it into the sun. We camp for weeks at a time without power with no problem keeping the battery charged.

Oh! I watched them all.

I guess, $5k worth of lithium batteries and a $3k inverter had something to do with them being able to run ac.

This video just points out the downfall of any shading of the panels.

I would love to add solar but so far the initial cost for a good system outweighs the benefits. Maybe our next rig will come with one from the factory. Until then I'll just run my Hondas on about 5 gallons of gas a week when boondocking.

It doesn't take long to charge up small golf cart batteries.

I built an off grid cabin up at our property about 12 miles from our house. 4 100 watt panels and 4 AGM 6 volt batteries 12VDC config. Works perfect. Solar is just fine if you set it up right.

Perfect!
So, the panels are stationary. You placed them where they would have full sun, no shadows.

The only point to this thread, is that no matter how many panels someone has, a bit of shade can knock them down to big ol zero.

I have not bothered with solar. The parks we frequent are full of trees. I am thinking of getting something small just for trickle charging the battery in storage.
