Home brew Arduino MPPT controller
Pretty cool project. Highly programmable. He does not list the amps it is capable of but I'm thinking 4-8 only based on the diode sizing. There are some very sophisticated MPPT algorithms out there...

Hi,
If you were going "all electric" then a large fuel cell might be the "way to go". It would power electric wheel motors.
I'd love to have panels that were double layered, with the bottom layer panels extending out once I've reached my destination for the day.
Another idea is a solar "trailer" that has lots of large 2 volt cells with a solar panel roof. When not traveling it would be easy to tilt the roof at an appropriate angle. I'd aim at a 48 volt system with a nice big pure sine wave inverter. That could provide up to about 40 kwh of power storage. Another potential battery might be one that is no longer suitable for a BEV car. With 100,000 bev's on the road, sooner or later used banks may be available.
For weekend trips I'm already able to be fully electric. For week long trips where I'm traveling significant distances each day, I again am nearly 100% electric. It is only when I'm in one location for more than two days that I have a power short fall. That is solved by moving the fridge to propane.
I've just ordered external and internal window covers from my local seamstress. I have pillows for the vents and home brew pillows for the sky lights. The external cover that will be the hardest is for the windshield. The "package" will also have a way to block off the cab area to cut down on the area to be cooled and heated.
The cheapest route for me to have more charging capacity without a generator would be to add a second alternator
