Oh, I also added a Viair OBA (on board air) setup. I put a coupler in the front grill and one on the side of the rear receiver and built a rack for it between the underfloor storage box and the rear axle. I have no pics of it so I guess Marc can post some if he feels like it, but it's not really much to see.

I strongly recommend this kit. It comes with everything you need.

Looks great.

One question.. are not solar panels meant to have some air flow underneath so as to not overheat and lower efficiency?

Not that I know of but these aren't sitting flat on the roof. There's a little room under there, 1/2 to 3/4" I'd say. If that is a consideration I'd like to know!

First off, amazing re-do. That replacement canvas looks amazing!!


But yeah, solar panels lose about 4% voltage (basic efficiency) per every 10 degrees they heat up over 25C. I would think the bigger the air gap behind the panel the better off you are. Would venture a guess that these things can heat up into the 60-80C range pretty easily.

So I have started 3 different comments, and cancelled each of them. Just no words. I'll try again later

Did you test if there were any impacts to the solar output with the crossbars so close? Based on Jage's solar shading video, I would be concerned that the power output might be a lot less than ideal conditions.

Marc's last panel (60 watt) was flat mounted to the roof with a bar right over the center of it and charging his batteries pretty well. He wanted the new panels under the bars to accommodate a boat he carries on occasion. At some angles these will have a shadow on them but from most angles they're wide open. They were putting out plenty of juice in my shaded yard when he left, even grabbing some power in my shop through the skylights.
