Hey gang, I used Jim Bennett's semi-flexible panel install as a model to add two 100w panels to the roof of my 21C.
All in all it was much easier than I thought it would be. Wish there was a little more room to add some more.
I used the
WindyNation 100w from Lowe's. They fit the exact width of the top section on the 21c. You can kinda see it in the picture. Originally I was going for the Renogy 100w but they were six inches longer and wouldn't fit.
Total cost for the panels, cables, and eternabond was just over $300.
