After spending many years forcing those "off the shelf" flat mounts to work on RV roofs, we came up with a much simpler and less expensive way to meet almost any mounting situation we've found in the RV world. They are called "Rocker Feet" mounts.
We make them out of laser-cut, stainless steel so there are no sharp edges to cut yourself on and your hands won't turn grey from handling them (like aluminum mounts). These mounts conform to any roof shape, allow easy access to the back of the panel for troubleshooting, or for cleaning, and will allow you to tilt your panels with the addition of an inexpensive set of tilt bars.
Of course, for these to work their best, we had to design an adapter that places embedded nuts on the ENDS of the frame (instead of bolt holes on the back like others).
By having embedded nuts on the ends of the frame, it allows the full use of our "rocker feet" mounts. The mounts can be swiveled to conform to any roof shape and attach with a single bolt (or UV resistant Knob) and a lock washer. Believe me, this saves a lot of time and frustration! This configuration also allows you to easily "flip" the panel over for access to the back of it.
For tilting the panels, all you do is remove two bolts (or knobs), tilt the panel up, insert the optional tilt bars, and bolt it in place. Simple, effective and inexpensive.
Why didn't anyone think of this before? Probably because all other solar electric systems are designed for applications other than RV use. Our Pre-configured SunRunner Systems are designed specifically for RVs!
