Mounting Solar panels on roof
Putting holes in any roof is a big decision maker, but if done correctly everything will be OK.
Here is what I did to mount my solar panel on our Eagle 284BHS. I called a RV place in CA that sets up RV's for solar and inquired about mounting the panel(s) on the roof of my Eagle. They said that it is not necessary to locate the the trusses in the roof as the roof decking is 3/8" thick (on my Eagle), and the trusses would not line up with the panel anyway. I used 8 solar panel mounting brackets (Z Brackets). I situated the panel on the roof where it was going to be mounted, marked the new mounting holes in the panel frame for the brackets. I then mounted the brackets on the panel and marked where I needed to pre-drill the holes in the roof. After pre-drilling the holes in the roof, I cut a couple pieces of white water hose and sliced them length wise, and placed them between the solar panel and the peak of the roof, so that the metal would not cut into the roof. I then filled all the holes in the roof with the roof sealant (Dicor) and spread it over the area where the brackets would sit on the roof. I then mounted the panel with #14 x 1 1/4 screws, which are more that enough to do the job. I poured roofing sealant over the brackets and screws. I used white wire channels under the awning to get the wires from the back of the roof to the front storage section. They have a sticky side and look/work great.
I did this project about 18 months ago and traveled over 8K miles (Colorado..... GA, IL and back) with no issues at all. We encountered cross winds (at Wilson Lake) of over 40 mph in KS for 3 days with no issues. I kept checking the brackets and wire each time we get to a CC. I attached a link to my album that shows the solar panel mounted on the roof.
I will be adding panel # 2 (and possibly #3 as we are looking at more dry-camping) at the end of the year and 2 more T145 batteries to increase my Ah to 520Ah. I have yet to turn on my TT's battery charge controller since I installed my 250 watt panel.....
What type of battery setup do you have on the trailer?
Any questions just yell!!!
Good luck, hope this helps
