Brian, I am happy you posted this video. After I watched your first video on mounting solar panels on channel strut, I decided to do the same. However, after speaking with a professional installer, I opted to drill a few holes to provide additional support. The installer said he had seen panels detach from RV roofs, particularly rubber roofs. Also, I spoke with 3M engineers who said 3M did not recommend using their VHB tape for solar panel roof mounting since they had not done the type of testing necessary to validate its suitability. In addition, I leaned there are several types of VHB tape for different type applications, some for metal-to-metal bonding, others for metal to non-metal materials, etc. 3M also recommended a primer to strengthen the bond to certain non-metallic surfaces. I used solid aluminum channel (without the slots), a 45 mill thickness VHB tape for metal to non-metal applications, a 3M primer applied to my EPDM roof, and drilled three holes in each piece of strut, one at each end and one in the middle. Everything has held up fine so far.

Almost a year...I installed them in late Sept but didn't release the video right away.

I'm glad u put the scews in your roof. No matter what, relying on just adhesive strength is risky, especially for this application. Also, high quality stainless steel mounting hardware and tilt bars can be purchased from AM Solar.

Back in my solar installer days, I was often asked to do RV installs. I did at least 50 modules of various sizes on various types roofs. My first way to do it was to work off of a roof rack, if there was one. Most often though I used EPDM rubber "donuts", 7/16" dia., that had a brass 1/4" threaded insert bonded into them. I'd bolt my stand off legs to the modules first, then when on the roof and where I wanted them (away from shadowing structures as much as possible) I'd drill thru my braket legs into the roof with a 1/4" drill, all 4, then shift it enough to enlarge the hole to 7/16", and with a twisting motion insert the rubber bushing into the roof, re-position the module, and using 3/4" stainless 1/4" bolts, torque them down. NO caulk, no leaks, and never had one come loose. I bench tested the holding power of them first of course, to prove the concept to myself. Your no fastener at all method is yet another approach. For the last 5 years or more, my go to caulk OR glue is a product called Lexal, I get it at Ace Hardware. It outperforms silicone types hands down, and it's best described as an "adhesive caulk." It stays pliable, is crystal clear (or white) and is especially rated for any plastic to any other plastic, though I use it about anywhere.

I like the smaller tubes, rather than the caulk gun sizes, they are less then 10 bucks I think, worth it! I have used it on my LSA plane a lot, one favorite trick is, for instance, when routing something like a GPS or Sirius SAT radio coax cable inside the cabin, rather than use mechanical fasteners of some type, I use the clear Lexal, just a dab every few inches, and some masking tape until it sets up. Next day, tape off, cable stays put and you can't see the Lexal.

👍 Nice job, thanks. I plan on doing that very same mounting technique as to allow for some of those appliance lifting air bags to be utilized underneath the panels (cross member mid way with plate) to raise the panel. A spring or springs would work to keep the panel wind safe while stationary and some quick type of lock downs for traveling. As you have two rows of panels a simple selection valve at the air pump would suffice. Combine the air bag release tubes together and have a single going to a convenient place to lower. A proper timer to the pump could be programmed for it to "follow" the sun, and just drop them back down in the morning.

Hi Tito, guess my other comment on the first install of these panels hasn't been read but you've done what I saw as a potential lift and your solution of the leading edge baffle in a word, excellent! Unfortunately to tilt the panels means a trip to the roof each time, this is where the solar panel side shade idea you had would be less work to aim at the sun and keep the side of the RV cooler being shaded by the panels. The side mount with your baffle is just getting better, I finished my initial lithium battery install yesterday so my project is moving forward. Thanks for your tips and insight.

With 8000+ watt-hours of 24v lithium BigBattery and the converter from the alternator, I could go indefinitely without plugging in. I didn’t even have a generator on that rig.

@@joeboxter3635 Over a 24 hour period, we typically run the batteries down about 15%-20%. During the day, we charge batteries from the chassis alternator (about 40 amps) and the solar arrays (the 850 watts usually produces 300-500 watts in most conditions). With a few hours of driving and/or some decent sunlight, we get that 20% back within four to six hours. We’re essentially able to go indefinitely without shore power. Of course, running the AC changes everything. I get 2-4 hours before the batteries are depleted with the AC running.

Didn't know that. Thanks! Creates added strength I'm sure.

hmm.... for solving some issues like: - having options to re-do panel configuration in future, - better height for improved hot air escape etc. P/Starb + B/Stern mounting solution- might could solve above - Permanent Base Rails @ P/Starb direction : mount like you did; one's chosen rail system, across roof in Port to Starboard direction (P/Starb) at a measured planned distance apart... say from bow end of roof, bond permanently rails in P/Starb direction, every 2 feet? Do this all way to the back Bow to Stern. - Reconfigurable upper rails @ B/Stern direction : atop Permanent Base rails; using that rails bolt on mount system, place sections of rails that run Bow to Stern (B/Stern). Place these sections to match where needed for panel mounting, All the panels etc. are mounted with these upper B/Stern rails. Bolt atop the Base; where needed, some small P/Starb, or B/Stern sections of rail , to use for clamping the panels on an edge where needed. Now your panels are further off roof by 0.50 to 0.75 inches than just one rail as you did . This should aid heat escape issue.. AND best of all... now your panel lay out is completely reconfigurable. Just unbolt Bow/Stern rails from their Permanent Base Rail and move them, and the panel attached to them, to where newly desired. Hmmm on second thought. for those with curved RV roofs etc.. the Permanent base rails going P/Starb may need to be in sections and not one rail all the way across in order to help deal with the curve. ... or guess one could slice the vertical sides of Base Rail in a few places allowing one to bend the bottom face till whole thing matches the roofs' curve. Luckily a problem I wont have with my Ambulance boxes flat roof..

I like the idea of no drilling but eventually the adhesive will give up due to temp changes. Even tiles on the shuttle eventually came loose. I would have a safety leash for when they come loose so no one dies on the highway.

Is the hassle of climbing on the roof worth it, installing the riser brackets to tilt panels for optimal charging? How much more power do you get?

I would suggest going with nylock nuts instead. ( A locknut with a nylon insert) and ditch the lock washers in that situation. A flat washer in place of the L washers would be a better arrangement. If you used nut-serts in the panel, a dab of blue lock-tite would be appropriate.
