I mounted the SunRNR solar panel to the roof of the VX using stainless steel brackets riveted to the roof.

Have you tried it without the alternator? I am wondering if 130 watts is enough without the alt. I am running a 40 watt solar panel inside my car and it really seems to help hold the battery at a topped up level, saving gas by running the alt way less.

I added some side skirts to the panel.


3rd Brake light is mounted to the tail of the panel for now. It will be integrated into an aerodynamic tail section as time allows.


Welded up a battery box which will be mounted in the spare tire well.(EDIT: Ended up mounted behind drivers seat)

I really like the effort, and I hope it produces enough power to have a significant impact. I have an idea, looking at your snaps. Is the angle of the panel off "the template" a little? If it is I bet you can adjust it fairly easily. Then maybe this is a nice opportunity to build a kamm back, consolidating a gain. I wonder if the over-hang out the back is increasing drag for you. Have you considered a kamm?

Looks better with closed in sides, can you please take a pic with the hatch open.
I think if the hatch opens enough, then a solid none moving kamback could be easier to make, and possibly more effective as well.

Here it is with the hatch open






I plan to increase the rear angle and create a kamm back soon. For now, more open hatch area will be very helpful while installing the new 110# battery pack which should be here soon.

Today, I removed the alternator charge wire for testing. The panel seems to put out enough to run the car with little to no battery discharge.

That is a serious solar panel. It must put out 5 or10 amps on a sunny day. If your car uses 10 amps to run , lets say your panel is putting out 6 amps, your battery would only have to carry 4 amps. 4 amps an hour is not going to drain the battery. I have complete faith in your Solar charging system. Adding some high output led spot lights flush to the grill block would be a nice feature. One that i plan on doing to my Beetle. Its headlights are weak and suck amps.

It was time to make the car a solid color. This army green is more suitable.

I built the side skirts and front lip for less than $20 worth of Coroplastic from Creative Press sign shop in Ruckersville Virginia.
