I find it frustrating with all the multijunction research out there that there isn't "reasonable" high-efficiency cells you can get that aren't 1000x the cost of a regular silicon cell, if available at all. Maybe my google searches / interpretation of the Amazon supplier truth vs fiction is poor in this area though. Because multijunction should be able to produce maybe 2x the power from the same surface area? I think the commodity efficiency panel is 15-20%, while multijunction can get to 30-40% IIRC. It continues to mystify me why a viable hybrid-drivetrain RV isn't out there on the market, especially since RVs can go so high end. A typical RV has a battery, generator, etc, yet has these clunky drivetrains with poor torque and shitty hard shifts (experience: driving RVs over the appalachian and the foothills) An hybrid EV drivetrain would have a lot more torque available, would be smoother, have regenerative braking, and it already needs a battery and a generator, so a range extender and the like shouldn't add too much to the system. Having a solar array would be a nice bonus, especially plopping down somewhere off grid for a few days. There's the roof real estate + the canopy/sunshield when parked. I find it hard to believe the Indiana RV cartel has an insurmountable grip on RVs. They seem so ripe for disruption, especially once the EV tractor trailers start selling in volume. Of course the hybrid drivetrain problem isn't the RV makers problems, it's that Ford/GM never made one either. Does anyone know why? You'd think the commercial lifetimes would "payback" the initial investment premium.
