Materials You'll Need for this Project
- Corrugated Plastic Sheet (size of panel)
- 6 x 1” Stainless Steel Carriage Bolts (¼ - 20)
- 6 x ¼” x 1” Stainless Steel Washer
- 6 (or 12) ¼” - 20 Stainless Steel Bolts (double for locking)
- 6 x ¼” - 20 Stainless Steel Wingnuts (optional if using bolts)
- 4 x ¼” Lock washers
- Aluminum transition strip (for front edge)
- Lock Tight (optional)
- 3M VHB Tape (amzn.to/2FzZK6D)
- 4" Eternabond Tape (amzn.to/2JfezN0)
How to make the Solar Panel Mount
(1) Cut insulator plastic sheet to fit solar panel
(2) Drill ¼” holes through grommets
(3) Cutout bottom of pla7stic insulator under each hole with utility knife deep enough for carriage bolts to be flush with surface (don’t cut all the way through)
(4) Cut six 2” sections of aluminum transition as anchors for the bolts (one for each hole)
(5) Round edges and remove sharp edges of aluminum anchor pieces
(6) Cut 2” x ¼” notches by each hole for each aluminum anchor
(7) Cut front-edge lift cover to the width of the solar panel (smooth edges)
(8) Drill ¼” holes in all anchors
(9) Pre-assemble insulator, bolts and anchors (leave solar panel off for now)
NOTE: Holes are not necessary for the front lift cover. The bolts will not go through the lift cover so that it can be easily lifted off. The lift cover will be held in place by the large washers under each front edge mounting point. Cut grooves if desired around the bolts.
Installation Instructions
(1) Clean roof surface with rubbing alcohol
(2) Position pre-assembled plastic insulator on roof
(3) Secure edges with VHB tape (A couple pieces near each anchor point on each side should do)
(4) Position solar panel over mount aligning the bolts through the grommets
(5) Cut a section of Eternabond Tape to cover each anchor point
(6) Cut a small hole through each piece of tape for the bolt to go through
(7) Remove the tape backing for each secure the tape over each mounting point
(8) Position the front-edge lift cover over the front edge and secure front with Eternabond
NOTE: The Eternabond tape should function as a hinge to allow the front-cover to be easily lifted off.
(9) Install the washers and bolts on each anchor point
NOTE: If you use wingnuts, consider adding some Lock Tight on the threads. You can also double up the bolts for added security.

@jasonolson342 3 года назад

Awesome video, personally I would use elevator bolts. Maybe epoxy them to the roof as well. Also remember if you are using ANY stainless to use anti-seize or STL to prevent galling. If you line up the wing nuts forward to back before you set them to the roof all you have to do is take a quick look on top to see if any wing nuts have turned off of the forward to rearward orientation. Nice job!!

Excellent solution for: 1. Stealth install with a very low profile. 2. Air flow to cool the panels and water drainage. 3. No holes in the roof. 4. Front of panel secured to prevent air sailing. This type of install will extend the life of the panel.

@RVwithTito 5 лет назад

I'm hoping it helps extend the panel life.

@geraldhenrickson7472 4 года назад

Most panels fail due to the abuse that UV radiation can dish out. Adhering directly to metal can actually act as a heat sink yet with a quality panel...heat is not an issue. BTW...stealth is a lost art. Law enforcement and concerned citizens are usually supported by the latest ordinances to prevent anyone to stealth camp in many, if not most, neighborhoods and business districts. It was easy in the 80's and 90's...nowadays...not so much. I recomends getting out of the cities onto public land. Its wonderful.

@merlecoggins7712 5 лет назад

That looks like a pretty nice solution. I've been considering adding a solar panel to the top of my pop-up camper and I might use this method. However, I would probably use elevator bolts instead of carriage bolts. Elevator bolts usually have a larger, flatter, head so you wouldn't have to cut out material to accommodate the carriage bolt head. You can also find elevator bolts with spike grippers under the head that would help keep them from spinning.

@RVwithTito 5 лет назад

I've also started putting tape under the bolt so it doesn't make direct contact to the roof. Good luck with your project!

@FrankVelo 4 года назад

Elevator bolts is the exact method I'll also be using - with a 1 1/4" head, I can use pre-cut VHB circles for easy install.

@richberman8260 3 года назад

Hello Tito, I used this method and it completely failed. Yes there is a flex panel somewhere in the middle of the desert. After we lost the first one we reinforced the second with eternobond all the way around. Then on our next trip it flew off. A truck passing by flagged me down and I was able to find it. So now we're starting over again however I'm thinking that driving in the 100+ degree temps is softening up the glue so that's the reason it's not holding. We're now thinking of adding some of the double sided tape under the panel (yes we have the insulator) then attach the panels with 6 screws, and then use the tape everywhere else. Do you have any recommendations on the type of screw or any other recommendations on how I can secure the panel on the roof? Thank you

@johnryerson1872 4 года назад

One of my two panels flew off my van using this method, going 80mph down a highway in high winds. Panels were mounted horizontally across the roof, one in front of the other (that's one point of difference; these are mounted "vertically" down the length of the roof). I also didn't attach that transition strip to the back panel, the one that flew off, so maybe that's what did it in. Panel was still attached to the corrugated plastic when it flew off. But I can't risk trying this method again. Not sure why no one else seems to have had problems.

@mjremy2605 Год назад

Nothing wrong with over thinking it. Better than regrets. But don't get analysis paralysis. Sometimes jumping in and buying one item and tackling a small project illuminates bigger ones. If you want to now best products - see Humble Road videos for electrical components. Solar panels are independent from rest of the items. Stick to lightweight panels not heavy glass ones. Mount like Tito did, best way I've seen. Keep them covered up so you don't get a shock or electricity being generated till you are ready to use them. Run a fake line like a string thru your existing roof vents like Fridge. Once the string is inside the RV decide where it needs to go for hookup and how long it needs to be. Your wire thickness depends on length. Mock it up first. Then make cardboard mockups of all the electrical devices you need and mount them in RV. Once it is all set in place and you worked out the kinks, do your ordering. Best Inverter is Victron. The Multiplus 2 can handle both lithium and AGM (Lead acid) batteries, and is also a battery charger and inverter. It is a True Sine Inverter not Modified Sine. Do not use a Modified Sine or your 110V appliances will fry. Always True Sine! Get a 2000 Watt inverter for most things as 3000 watt is pretty high. The bigger inverters will also sip more power as they are turned on. You only need an inverter turned on when you use 110V power from the batteries. 12V lights and fans, water pump, fridge mostly run without the inverter. Best solar charge controller (SCC) is Victron MPPT (not PWM). For a 30 amp SCC, you can mount a max of 400 watts of solar. If you mount 420 watts, you need another 30 amp SCC. It is better to get two SCCs at 30 amps each than one at 60 amps. Easier to have two systems if one malfunctions. The other one is still working. Safety code issues with your wiring diagram, wire gauges, wire heating all covered by Greg Virgoe. He is a great teacher and UK certified electrician. Where do you start? With your own requirements. Start camping and note what you want and need. Hair dryer? Toaster, coffee maker or French Press? Run AC on batteries or no AC? Run fridge on AC or use old tech propane fridge? Make a list. Then determine size of inverter you need. Then decide how much lithium battery bank size you need and can afford. You can keep adding batteries, and solar panels but not inverters. Also you could have a small dedicated inverter for your CPAP machine at night so the big power hog can be turned off. Requirements are key and you need to know yours first.

@mikemonster349 4 года назад

Jeff, I'm getting ready to use Brian's method of mounting panels and also agree that "elevator bolts" seem to be a good option over standard carriage bolts. With the flush heads it seems it will eliminate cutting out a layer of the plastic card board so this will retain integrity and strength of the PCB. I'm also going to use 3/4" bolts rather that 1" to eliminate the extra threads sticking up above the wing nuts. I'm considering 3M VHB tape rather than Eternabond for bonding but would appreciate comments. Lastly, Brian thanks for a great site/channel !!

I made a PVC awning/portable mount using your previous video. Thank you for that. And boy, those panels get HOT in direct sunlight.

@RVwithTito 5 лет назад

The front edge is covered by the aluminium piece so front to back orientation wouldn't work. The side orientation is also for proper drainage since the panels are on a very slight downward side angle.

@geraldhenrickson7472 5 лет назад

Panel heating has been the demise of many a panel made with the wrong materials. Do some research and you will find panels that can take tremendous heat and still have most of their output after 10-15 or even 20 years. I have a Uni-Solar panel that is 13 years old... very little degredation. My neighbor has had all his panels (four identical from the same manufacturer) die within 3 years. He went the lesser quality route. They were beautiful panels but the materials just did not hold up well. I have a total of 13 amorphous panels that all look about the same as when I bought them yet were never fancy looking. They are also larger than the equivilant crystaline panels so more real estate is needed.

Fantastic segment Tito, thankyou. Curious, since this was done yrs. ago, any new thoughts about how it's held up since the initial install? Also, did you have flexible panels that over heated previously and shortened their life and or caused less wattage efficiency prior to mounting these panels this way? I saw what looked like smurf tube on your roof. Is that to protect the wires from uv damage to the outer jacket of the wires? Just curious. Thanks again. This really made sense in so many ways. Especially not drilling into the roof.

@RVwithTito Год назад

I did have one die before I tried this method. Eventually I got better quality solar panels and upgraded my mounting system to this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uJIEXhnF8MU.html Yes. The cable wrap is just to make it look nicer and protect the cables better.

@ivyshy98 5 лет назад

surprising you went with flexible again after the first failures. yeah I know sunpower is a better brand but the issue is heat dissipation which I'm not sure the that plastic board will be enough. I mean, they are warrantied for 5 years instead of 25-30 for a reason. I'm certain with the money you save with normal panels (thinner frameless ones do exist now) you could get a rack mount to allow more clearance between the panel and rv roof. I mean it's an rv so it doesn't need to be steal or anything. well hope your solution works.

RV with Tito DIY - I like the over all concept, but you may have some design flaws. Is the VHB holding down just the aluminum strips or is it in contact with the heads of the carriage bolts so they won't turn when it comes to removing the wing nuts? It hasn't been a problem so far as you removed the wing nuts to install Locktite. Now that you added Locktite there is a chance when you try to remove the wing nuts that the whole assembly will remain locked up solid and just twist and tear. You secured the front aluminum strip with Eternabond I hope that it is flexible enough that you can bend it out of the way if you have to change panels. I hope I'm wrong and that you have no problems.

I may be the first one to ask...Aluminum with stainless steel? Isn't there an increased chance of the steel causing the aluminum to corrode? I know when ever we do aluminum on a hose siding soffit/facia etc we must use aluminum fasteners to prevent the "electrolosis" reaction between dis-similar metals.

@rvlee8577 5 лет назад

What a perfectly fantastic system Brian. Thank you for saving me countless hours in Home Depot mumbling " Will this work?, would that work?

@RVwithTito 5 лет назад

At my Home Depot (actuall I have 2 nearby) those transitions were gone. Then recently restocked. You could also bend a piece of aluminum flashing to get the same result. By the way, I'm usually that guy wandering the halls of Home Depot mumbling. Cheers.

Excellent video, idea etc! I want to use your idea and instructions to attach a 100 watt flexible solar panel to my BOAT's fiberglass hardtop. Any comments or ideas on that change of vehicle as I get a lot of wind from all directions at times when storms roll thru. I suppose you too experience those gusty side winds in your RV but maybe not as much or as often as we do close to the Atlantic ocean during storms. Your thoughts and those of your subscribers will be appreciated. I am powering a Bluetti A180 for my electrical needs rather than carrying a heavy, smelly generator. It works great as shore power charges it, as well as the outboard charges it and soon the sun will charge it. Thanks for a great idea from someone who does not like to put holes in boats, even above the waterline!

@RVwithTito 7 месяцев назад

These flex panels were primarily designed for boats. So you should be good. There may even be some marine grade twist lock fastener that could work through the grommets. I've also seen these panels sewn into a Bimini and anchored with velcro. Hope this gives you some ideas.

Excellent Video!! I am still a bit skeptical about the life of flexible panels vs "rigid"; not sure if it is general/overall heat dissipation but I think you have pretty much nailed it. I guess for me, if this is pretty much a permanent mount I wouldn't have used wing-nuts and locking nuts instead, and perhaps applied a little adhesive in the central area to ensure the panel doesn't "vibrate" and weaken the internal crystalline structure via venturi effect. (My wind tunnel is down at the moment and I can't test - j/k). If the panel goes bad I am not wasting much money throwing away the insulated backing along with it... as to warranty replacement, yeah they are going to want a pristine panel so maybe no adhesive or something that can be peeled off if / when needed. Anyway, this is one of the best thought out installation ideas I have ever seen!! -Many Thanks!

@RVwithTito 5 лет назад

@geraldhenrickson7472 5 лет назад

Some panels are noy crystaline at all and are a bit more hardy. They are amorphous panels. As for warranty...many companies are now reluctant to help the DIY'r. On the bright side, if you purchase quality equipment...panels, controller, inverter and batteries...you will likely not need a warranty.

I like all your projects. This is a super simple way to attach the flexible solar panels.

Well thought out installation procedure. Please let us all know how this weathers over the years. NOTE: there have been reports of flexible solar panels totally failing if installed directly to metal roofs with no thin layer of insulation underneath the panel. This seems likely to be a thermal overload failure, especially with flexible panels that have an aluminum backing that was probably intended to be a rustproof heat sink. Most likely solar heating accumulation on a metal roof with insulation on the passenger compartment side was transferred to the solar cells via their aluminum backing, thus overheating them. (It would be useful to verify this if others have had the same experience.)

@lorcro2000 5 лет назад

I think going with hard panels is smarter anyway. They're more efficient, durable and perform better. A bit of a pain to install, but if you do that right you can even create a way to tilt them up using actuators (for example, a frame made out of 8020 t-slot) and thus increase solar collection efficiency hugely when the sun isn't directly overhead.

@RVwithTito 5 лет назад

Sure. You're not alone. Many prefer traditional panels. I'm not trying to change anyone's mind, just sharing what I'm trying out for those who are interested.

@geraldhenrickson7472 5 лет назад

Most, if not all panels can be used for battery charging OR ...to tie into the power grid out on the street. It is the solar controller that determines what service the panel is capable of providing. NOTE the panels that tie into the public power grid have a complicated and costly array of controllers, cooling fanms and and other specialized equipment. Be careful what controller you purchase...some will not work in a stand-alone situation such as with an RV or remote cabin.

Interesting concept, just using tape, trusting soul in the blazing heat other than putting a carriage bolt in a round hole and the wingnuts, which should be double nutted with all the vibration. Now you’re trusting Loctite to do its job to keep those wingnuts from loosening not sure why you wouldn’t use nuts. nice job

and Coroplast, which is a specific brand of corrugated plastic.

@johnnylightning1491 Месяц назад

I know I'm a little late to the party but that piece on the leading edge seems to me like it will negate one possible advantage of the corrugated panel. If you orient the "tubes" in the panel toward the front of the RV you will get airflow through the panel which will basically cool the panel to ambient temperate while you are underway. I'm thinking that VHB tape between the roof, the corrugated panel and the solar panel will provide plenty of strength to prevent lift and give you good air flow through the panel. I'm getting ready to do this project so I'm thinking I might try this. Keep the good stuff coming.
