How To Install a Flexible Solar Panel on an RV


Hey guys, I’m pretty excited today, because I am finally going to try to install these new, flexible, solar panels on the roof of my RV and add them to my existing solar array on my roof. You know I tried to get these installed recently, but the weather at home just has not been cooperating and it’s just been one fail after another.

I’m in a more sunny location today and I thought I’d – try to get them installed and make this video for you guys, but a little bit about these. So these are, I got them off of Amazon, and these are 100 watt flexible.

You know thin solar panels. These are pretty good. I’ve done some preliminary testing on them and they are performing really well. I am excited to get these installed and again. This is not a full install for an RV solar system, but I have made several videos about installing you know the other components of my system.

So if you want to see those check, those out you know in the links or I’ll – try to put a link here somewhere. So yeah, let’s. Go let’s! Get these solar panels up on the roof. There’s, Melissa back there, helping hope you in the shot you don’t want to be in the shot you well.

I got all the stuff up here in the roof. Now all my tools and everything and I’m about ready to get started with this project. But before I did, I wanted to address a couple of questions that I frequently get asked, and one of them is: why did you end up going with flexible solar panels? Over the you know, standard rigid, solar panels and my my answer has always been the same.

It’s like I prefer the flexible panels for for one. I wanted to be able to still have full access to the roof of my RV and and not have any part of it obstructed. So I can’t. You know walk around and I’m up here on the roof a lot.

I understand also that that also prevents me from being able to tilt my solar panels. So I’m. Okay, with that, I know I’m, going to get some more benefit. If I’m able to tilt the panel’s at certain times a year, especially or certain times a day, but I’m.

Okay with that, I’m willing to take that to account for that, though, what I ended up doing is. I actually got another third solar panel that I’m, going to be installing and one of these same kind of installing today and I’m going to be installing that up.

You know towards the front. I have some more space to put that on so adding an extra hundred watt panel. Maybe that will make up for the fact that you know I can’t tilt my panel, the flexible solar panels, aren’t visible at all from the road, so there’s, nothing from the street level.

You can see. Oh roof is covered with solar panels, so I kind of like not having that solar panel thing all visible from the outside, so it just looks like standard roof from ground level. All in all, I’m, really happy with the flexible solar panel.

The other question I often get is a: are you going to hook them up in series or parallel? And today I’m, going to hook these up in series that’s, basically connecting all together from positive to negative positive to negative.

In one big chain and the reason I’m doing, that is because I’m using an MPPT charge controller. That gives me a lot of voltage coming off of the roof actually with all of them. Together, I’m. Going to get about 125 volts coming off the roof, I have more videos and more information about that specific topic.

So I’m, going to go ahead and link to those I’ll. Put a link up here where you guys can check them out and I encourage you to go. You know check out those other videos, because those are focused entirely on that subject so yeah.

So with that, I’m, going to go ahead and get started. Okay, now before, starting with the mounting, I’ve gone ahead and laid out the panels in the configuration that I actually want, and I just wanted to verify that everything is actually going to work correctly.

The way I want it to so, you know here’s, 100 watt solar panel there and another one over there and I’ve, actually hooked it all up in series. The way that I wanted to and it’s. All running through my charge controller now and I verified that I’ve got you know the voltage that I expected so just want to verify.

Are things going to work before I start drilling holes and mounting okay? Next, I’m. Just going to position the solar panel kind of right, where I want it and before I start mounting – and I measure that this panel here is about seven inches from the edge so yeah we’ll, keep it right about there.

I look good from Google Maps. You see that video that’s pretty awesome. I’m just going to mark these corners and the next thing I’m going to do. Is I’m going to attach these little velcro strips to the underside, so I went ahead and cut that piece of velcro head into four equal little pieces, and I’m going to just put two on this panel and two on The other, those on realign it to my my quarters here, you know Hey now I’m preparing to drill in to secure these this panel.

Now so what I’ve got is a one inch screw and I’m. Going to drill a little pilot hole, but I don’t want to go too deep. So what I’m going to do is get a piece of tape and just make sure that I am not going in too far.

I’m just going to put a little mark there on the drill bit, so I know when to stop. I went ahead and cut some little pieces of I guess pieces of these butyl from this butyl tape. So I’m, going to actually screw the screw through the butyl tape to give it a nice watertight seal.

I had some. I had some extra here from this role of a butyl tape that I used for my my my vent install so yeah. It’s, cut a few pieces from that and I’m going to get one for each hole. So let’s get to drilling okay.

Now I get the butyl tape. I put it underneath the hey the hole there. I’m just going to simply screw right through it. Okay, the panel seems pretty secure now. So I’m. Just going to repeat the whole process on the on the other panel get that mounted and then, when I’m, all done, I’m, going to seal it all up with some dike or all right panels are hold on there and They seem pretty secure, so final step is to kind of seal everything up with some with some dye core.

Now I could just put this over the screw holes just to kind of seal those up, because those are where the you know where there’s, actually holes in the roof. But I’m, going to seal up all the way around.

The panel, so let’s, see if I one tube of Dyke or does it for me. So hey go you and if I can do something about all these wires coming out bag of zip ties and get to work all right pretty exciting. I’m, going to call this one done for now, and you know panels are installed.

Yes yeah. I got ta. Let the dye course settle a little bit more, but it’s good. To do that when it’s. Warm out and yeah pretty happy with this, and I know a lot of you. You know when they start. Thinking of you know this type of install the number one question that usually comes to mind is I don’t know about drilling holes in the roof of my RV.

My opinion is it’s, really the safest and most secure way to do it. I’ve, tried other options and have actually lost solar panel before flying down the highway, with some sort of experimental mount dome.

But yeah I’m, pretty happy the way with the way it turned out, and I think it’s going to work really well. In fact, it already is here’s. The cool part come check this out. Okay, guys here’s, the exciting part, so with my previous solar setup in a gun a good day, you know down in the sunny spot like this, I would probably max out at about you know 16 amps, coming from my charge controller.

So now, with the new 100 watt panels, those two additional hundred watt panels – I am generating about 27 or more amps right now, so that is pretty exciting. I’m, actually running my refrigerator right now off of just off of the inverter and not off of a gas.

So I think this is going to work out really well and I can’t, wait to use it more, but this is going to wrap it up for this project guys. I hope you guys got something useful and good information out of this.

For your own project, if you have suggestions – or you know, tips for you know other ways to mount, especially these flexible, solar panels and things that you might have done, go ahead and share them in the comments below and if you liked the video you know give It a thumbs up and if you’re new here, you know subscribe, but I’m, going to go ahead and joy, this Sun in this beautiful location guys.

So I will see you guys later – take care.
