Very nice flexible panel install. What brand panels are they, and how did you attach them to the roof?
My panels were manufactured by Sun Power. I attached them with 3M VHB tape. Considered using SikaFlex 221 around the edges as well, but didn't. So far after two years the VHB has held up just fine.

Be careful, as moisture and dirt accumulation will eventually degrade the bonding hold of the VHB.

That's why we seal the edges of the mounting feet.

wiring through the roof

Thinking about a 200watt go power flex system for my 54 cruiser. Since the inner skin is off and Im currently wiring up the trailer Im figuring now might be a good time for the install. Does anyone know the best way to come down through the roof? Other installs Ive noticed connections bolted through the roof then attached with cables inside the skin.

I drilled a hole in the side of a Fantastic Fan housing and ran 10 ga wiring through a rubber grommet, connecting to factory prewire under the skin.

Renogy and HQST flexible panel failures

I've been a big fan of the flexible panels on my 1980 Caravelle. I had 2 Renogy 100W flex panels and 2 HQST 100W flex panels. I have them plugged into a Sunsaver Duo with remote meter and 2 6V golf cart batteries. It worked great for about a year, but in the heat of the summer, 3 out of 4 of my panels failed catastrophically while I was out of town. I returned from vacation to find my batteries COMPLETELY dead (<9V) and unable to charge at all. I was able to return the batteries to Costco and get new ones before I figured out the solar panels were to blame. I started troubleshooting the solar system and was able to separate the MC4 connectors to test each panel separately. 3 out of the 4 panels have zero voltage in full sun. One of my Renogy panels still looks good. Since everything is sealed except for the MC4 connection, I have no way of telling what the problem is with the panels but I am still under warranty. I'm going to install a couple monocrystalline rigid panels now since I don't want to go down this road again I don't know if Renogy and HQST will honor their warranty, but I hope they do. It adds about 30 pounds to my roof and may have an effect on aerodynamics, but at least they should last a lot longer.

If you have the interior skin off, I think that pass throughs are the best. It results in a very clean and versatile installation. Here are the Blue Sea terminal feed through connectors that I used:

I just went through a similar problem with 3 100W renogy panels. One still worked but the other 2 were as your were.
When I talked to them they acknowledged that they had had a problem with some and they offered a full refund even on the one that was still working as they knew that one 100W panel wasn't going to do me much good. They even shipped an empty container up ( to B.C.) and paid the whole freight.
I have been in contact with them as they are working on an improved panel and hope for a release in the new year.
I was totally impressed with the handling of the whole situation and wouldn't hesitate to deal with them again

We mounted the panels on the roof but did not adhere them directly to the surface. We used rubber grommets so that there would be a small space under the panel. Then we fastened the panels (through grommets) at the corners and halfway down each length. We wanted to have the spacers to ensure no water got trapped under the panels and so that they could be removed if necessary in the future. We apply a UV protective wax to the top of the panels a couple of times each year to keep them in good shape and to help grime from building up.

We couldn't be happier with the panels. I would post pictures but the trailer is all wrapped up in its winter cover right now.
@ 72Alumacoach: Do you recall the brand of the panels you purchased on Amazon?

Yes, they are HQRP panels that were distributed through Osprey-Talon. Doesn't look like they are around anymore.

Portable Go Power 80W

We have used the Go Power 80W portable unit for 3 years now and are very satisfied. Benefits are portability allows movement to optimal sun exposure vs fixed solar, and also cost. We installed the included quick disconnect cable to our batteries in front and tuck the cord in behind the aluminum propane cover. We secure with 6' cable lock, if we are concerned about possible theft in some locations, but no issues so far. The case allows for easy storage and we place under our table when traveling. For us, this allows us to take with us and if needed, can be used on other vehicles. Our neighbor had a SOB trailer last summer which after 3 days, needed a charge, so he borrowed our unit. 3 hours later he was fine. I would highly recommend for those not wanting the cost of permanent solar since you can take these units with you when you trade up. I would also suggest looking at the larger units (120W) if you want quicker charging.

solar flex panels

Went ahead and bought a pass through plate for the go power 200watt system. Drilled a hole just big enough to get the two cables through. Installed a grommet and then vulcumed the @><:"" out of it. Put more vulcum down around the plate and on the holes that I screwed it down with. Hopefully not leaks. Im fixing to secure the panels. Im curious how you do this with grommets. Im thinking the 3m tape but not sure Id trust it going down the highway at 70mph.

So much great information, so little time! Im in the process of removing subfloor in my Excella and I was thinking as I have the skins off it may be a good time to run solar wiring.
