And, now...the pics. First up is a level check in comparing the the curb-side and street-side panel frame edges.





They seem very close. I placed the panel as close to the TV antenna as possible to mitigate any effects from the front radial slope. I saw, upon closer inspection, that there is a bit of a crown before it slopes. So, that worked in my favor.

The next set of pics show how to place the 2" x 2" piece of Eternabond and to mark the spot for drilling the pilot hole.











Because these brackets are not Z-brackets, the panel has to be tilted in order to drill the holes for the street-side brackets.

The next couple of pics show the wiring in the combiner box and the enclosed waterproof box.






Now, I just have to get a pic of both panels catching some rays.

Are those wires in the combiner box coming direct from the panels, or did you have to splice the panel wire to make it longer.

Both panels come with about three feet of 12 AWG MC4 cable. To these short run cables, I had to connect a longer run to reach the combiner box. I ordered two 20' 8 AWG MC4 extension cables. The cables were cut to length, strategically, on the first panel install; so that, I was able to use the remaining length of both cables on the second panel install without having to install the MC4 connectors.

I forgot to measure; however, there appeared to be about six feet left over from both extension cables.

How did you stick the long cable to the roof?
I want a single 250 watt panel and it is about 64" long, the only spot to put is is at the front and the pre wired MC4 roof connection is near the back. That's a long cable run across the roof.
It would have made more sense for Jayco to put the connector at the front since the pre wire lands in the basement, it would have been 12' less wire x2 lengths and Jayco is all about saving every dime!

I haven't done wire management yet. However, the plan is to use a small length of 2" wide Eternabond to keep the wires from flapping around on the roof while at speed.

I have already put eight holes in the roof. I am not keen on putting anymore to keep wire in place. I have seen online other DIY installs use the tape while pro installs use screws. The pros do not have to worry about yet another source of water entry.

Excellent description and photos of your design and install, Sebring!
I think you've given novices like me some great ideas.
Can you add up your costs and give a bottom line on what the total cost of the materials was for you? It would be much appreciated. Thanks.

Thanks! It was roughly $1K for the parts specific to the solar installation. I will have to do a spreadsheet. I definitely price-shopped while making sure I was getting the right size wire, fuses, etc. for my install.

I still can't believe the roof supported my weight, haha!

I still have to do some wire management.
