UniSolar Panels Unisolar makes state of the art solar products. Established in 2007, producing systems such as Roof or Panel Grids on Mounts. Unisolar technology has an integration process that reduces electric consumption in the process of collecting light and inverting it to usable electricity.

They are also known for Solar outdoor lighting systems as well as portable charging systems. They even produce solar traffic and street lighting equipment. Since 2008 Unisolar has been making peel and stick solar panels that are in demand. Some are used as roofing since it has a 185 mph wind rating.


Unisolar makes nice peel and stick solar panels also. Very flexible and in demand at the moment. You can carry around easily or put in a cart, back of truck, it’s endless how maneuverable these are. They work great in low light situations also. I haven’t read a lot on how well they work when partially blocked but since they are portable that shouldn’t be too much of a problem. (if you’re go with that type)

There are other unisolar panels available. Wind is quickly becoming less of a factor with a lot of solar products these days also. Here’s the real reason I like them. Unisolar has some models that are glass free. Not worrying about cracked cells by getting hit too hard is a huge plus. Use them anywhere, RV’s , boats, cabins, even moving around in the yard or patio. They are made in the United States so shipping and any problems can be quickly addressed.

Unisolar is known for working in all kinds of situations. Partial shade, hazy days, etc. The PVL-128 and PVL-136 are popular model numbers but any of them really are a good deal. Even know Unisolar went under you can still find their stock on different sites.

It has a fantastic reputation of holding up from continuous use. Output stays good. There are precautions but overall it was/is an excellent panel to locate. It’s widely known that when Unisolar threw in the towel there were stockpiles of inventory around like I was saying earlier. The good news is places like eBay has lots of it…SEE ABOVE

Sometimes you can find really good prices for several of these panels. You can consider them new, they may have some years of sitting someplace but they were made so well it’s defiantly worth looking in to. You will want to make sure the voltage output of the panels is what you can work with but a lot of people figure this out because of Unisolar reputation of holding up. You will all your external components to match up like controllers and inverters.

Some panels are made with MC3 connectors and some with MC4 connectors. Some just had 2 wires out of the bottom. Like any business that is no longer around, Unisolar panels will have to warranty but they are known for lasting decades so this shouldn’t be an issue unless they are damaged somehow. Some people refer solar roof shingles because of their 18 foot length. The way they would lay out on the roof.

Some people buy a whole pallet of these panels when they can find them. It’s another reason I constantly check out eBay because that is where they show up lots of times. Their portability is excellent. They have been know to withstand being rolled up again and again and still have excellent output. As their legend grows because of all the good reviews on the net, the prices on anything unisolar is going to go up.

As I was saying earlier about Unisolars shingles (if they can be found) are in demand. They have received awards like Popular Science’s Grand Award and the Teleological Innovation Award by Discover Magazine. Almost anyone in solar envisions the day that solar components on a roof serve double duty as protection and a generation point for electricity. You would think this would be common place but not quite yet. Unisolar shingles have a blending pattern inherent as traditional asphalt shingles. From my research, UniSolar products are not affected by temperature as much as other brands. In an optimized system they have been know to outperform similar brands. Some reports talk of 20% more output whit factors of shade and cloudy days, etc.

This is a cool video. This gentleman is has some good shots of his 2.7 KW Unisolar panels on the roof. It’s a good breakdown of the system. Also discusses future plans.

Welcome back to the roof folks. Well I’ve got the battery compartment open for maintenance. I thought I’d explain the whole solar power system to you. I’ve got roughly 2.7 kilowatts of these uni solar flexible self-adhesive panels up here. They’re designed to go on a 16-inch standing seam roof running this way down here to the flat surface between the ribs but this is working just fine. That’s roofing is a good asset price is the same gauge metal and paint. Those panels are connected in strings of three in series with groups of three or brought back here to this panel and paralleled. Each get their own breaker and go out this conduit and the equipment room there it is with the first cover and moved here. The breakers one more for later actually going to need to get another one for later the plan to put six more panels on here over in that area and with the final cover removed you they’re all the negatives joined together in that bar panels grounded they’re all the positives run through the breakers coming in from the panel groups here and out the top to these bars combining it to this 8-gauge we’re going inside that’s running roughly between 80 and 90 volts when producing power lines coming from the roof and go through this disconnect for safety and serviceability and i am able to run 80 or 90 volts thanks to this MPPT charge controller which then converts it to the appropriate voltage to charge by 48 volt battery bank go through another disconnect this one with fuses and how to the batteries one set of wires coming through the wall over there from the charge controller is paralleled with these groups of three equal and players from each end of these series’s the battery’s eight of them and series here three groups of eight and parallel then the three strings of batteries and charge controller come together top of this great old time fuse holder and disconnect that i will not pull an out-and-out to the inverter which powers this sub panel replaced all of the circuits to be powered by solar this inverter is also a battery charger you run out of solar power and want to charge the batteries back up like red turn on this breaker here that would supply power to the charger and on through to the subpanel that was previously solar-powered and if the grid was to shut off well you have a great power on through this thing it would automatically transferred back to solar power battery power however you do it it has its own transfer switch that’s fast enough not to disturb anything automatic backup with this system were able to power just about everything in this small house including 200-foot well pump leaving out the dryer that would be silly and the water heater explain my plans of in previous video in the summer powers a couple of these little window units handle most of the cooling the central air can be powered either way through this transfer switch from my previous video is the central air outdoor unit is powered from the garage panel have this switch to decide what to paint the garage from course this battery compartment is normally sealed up so that the gases event outside through the roof and I think that’s about it thanks for watching feel free to post any questions


Another do it yourself with a flexible solar panel on an RV…I love these types!

hello everybody hope your summer is going great you know mine is so far it’s been pretty busy but today I got some time it’s Saturday and it’s pretty nice day sun’s out slightly so my neighbors are out frantically cutting their grass weed whacking doing all those things that I normally would be doing but today I’m going to take on a different kind of project project for good ol RV here you know to me nothing’s as exciting is harnessing the raw power of the Sun to generate electricity now in order to get power for the Sun you’re going to need a few things obviously some kind of solar panel or collection device you need a charge controller and it’s going to hook to your batteries and you need some cabling and you have to figure out how to run that wire within your RV so this is a different kind of a panel that I picked up from a company called yuna solar actually I got it on Amazon for a steal it’s flexible pieceof on the bottom so it’s going to stick right to my roof and you won’t even know it’s there and this one generates 128 watts and I’m really excited to put it to use so I’m going to go ahead and get started I can’t wait to see how it turns out okay so now I’m up on the roof of the Motorhome and I’ve gone ahead and laid out the panel the way it’s going to look on the roof it’s not stuck to the roof yet but what I want to do is just test all the connections and make sure it’s going to be charging okay like I expect so here’s what it looks like I’ll laid out on the roof you can see this one’s kind of long and it it’s actually 200 and about 215 inches yeah the really cool thing about it is it’s just really low profile and it’s a you won’t even notice actually looking at it from the from the road so I already comes with connections that are going to connect to my charge controller what I’m going to do is I have a an old RV battery with the charge controller hooked up to it so I’m going to go ahead and test the the connections to see if it’s actually going to charge right now it’s a good see it’s really not that sunny out so I probably am NOT going to get a whole lot of current running through it but but it should be plenty to test so let’s go ahead and go down and add go to the battery okay so I’m back on the ground now and what I’ve got here is a two connections coming up with a solar panel so what I can do it’s not connected anything yet what I can do just see what kind of voltage I’m getting out of the panel before I hook it up to the charge controller okay so even with some cloud cover I’m getting about 41 point 6 volts out of this panel so now going to go ahead and set it up to my my little test battery here and check the connections and before we actually hook it up to the RV okay now I’ve got the solar panel hooked up to the my MPPT charge controllers is a 30 30 amp controller I don’t this panels not going to generate up to 30 amps but a you know it’s good to be safe so you can see right now I’m checking the on the controller side I got my voltage meter hooked up to the incoming panel connections positive and negative you can see it’s kind of fluctuating right there between 22 and 25 volts so what did what the charge controller did is it a kind of increased my current and reduce the reduce the volts on the panel so this is a more intelligent controller that’s going to basically optimize the output of your panel and that’s what the MPPT controllers do more about that on the blog I’ll put some more information about MPPT I have to learn about it pretty cool stuff so now if I look at my actually you can see that the blinking light there means that it’s charging that the MPPT is working I’ve got the output charging this battery so I’m going to go in the battery side and you’ll notice that my voltage on the battery is kind of steadily climbing 20 mils 12.7 I was twelve point eight and I was twelve point nine and that’s what the MPPT algorithms do is they just kind of gradually start increasing the voltage on your on your battery and while also giving you more current so it’s sucking more current out of the incoming incoming volts from your panel so it’s getting the most most out of your panel you’ll see some of these listed as a 30% boost in performance these MPPT controllers so this is a fairly inexpensive one I paid a little over $100 for it you can certainly get some really expensive one so this one seems we working fine as long as you don’t as long as you connect it to according to the instructions so yeah so my test seems to be working pretty good I’m pretty happy with the hookup so now I all I have to do is basically put the panel on the roof clean the surface get it stuck down and run some cabling it’s going to be the hardest part I think is going to be is going to be running all the wiring into the inside of the coach and hooking it up so I’m going to go ahead and get started okay now first things first getting ready to put the handle down on the roof but before I did before I do that I went ahead and made sure the roof was nice and clean he uses his camco rubber roof cleaner I want to start with a nice clean roof because this thing’s going to be down somewhat permanently so now I got a nice clean roof and I did this another day and now I’m ready to go ahead and lay the panel out the way I want it and get it to get it adhered to the roof so go ahead and do that get exciting okay so now this panel is on the roof and it’s on there for good so it’s not moving so next step is to do some wiring and I’m going to run the cables let’s see it comes with the pre-wired cable so I have some summit cables that you saw earlier and I’m going to go ahead and run those over to already figure this out run this over to this event and hopefully run it down you have to maybe drill enlarge this hole a little bit and it should come down right near my bathroom which should be able to run it too near where all of my power is so so that’s the next task is to is to pull some cable and I’ll tidy all these things up later looking good huh okay so I’ve successfully run the cable from from the solar panel down through the wall through these little cracks and crevices into the kind of the belly of the beast here this is where all the power comes in and my inverter is here and I know how I’m going to hook this up so I’ve made this fuse thing right now so I’m basically doing a bunch of wiring and I’m getting this getting this thing all wrapped up I got my charge controller here it’s going to be mounted kind of out of the way my wife thinks this is kind of ugly so I don’t really want to put it in a place it’s not going to be readily seen so here’s a picture of the crime scene so all the electronics most electronics in my rake anyway are are located under my bed in the bedroom area so here’s my converter there’s the automatic transfer switch okay I’m going to be hooking up the a charge controller to my battery through this connections through these connections down here and so yes I got kind of a lot of stuff laying around doing a lot of wiring right now and looks kind of like a mess so if this kind of scares you then this project is probably not for you you kind of have to know a little bit about how your rig is wired and especially where the power comes from anyway I’m going to continue on I’m going to get all this wiring done and should be able to wrap this up pretty soon and at least get to where I’m charging right now I have all the power shut off batteries are disconnected all the short powers is connected so god be safe right and we’ll see how it turns out so we’ll check back when I’m done okay now everything’s hooked up and everything seems to be working properly so it’s about time to put the wraps on this project but let’s go see how everything turned out so let’s take a look at the charge controller as I mentioned earlier I wanted to mount it somewhere out of the way because it’s a my wife thinks it’s kind of an eyesore I didn’t want to spend hundreds and hundreds of dollars for a really nice flush mounted one so this one will do works just fine so we take a look at it you can see that the blinking red light indicates that it the panel is charging my batteries batteries are pretty well charged at the moment and you can see where I’m on and it’s kind of right right under my bed out of the way but still accessible so the hook-up on this is pretty easy I’ve actually have actually been messing with it for a while now let’s go up on the roof and take a look at the panel finished product see now when it’s sunny out I get real excited knowing that my batteries being charged in the solar panel is just getting that free energy from the Sun let’s take a look at the panel so I you know showed you earlier I got it all mounted and stuck to the roof so a few finishing touches here I painted the cable companion white so it kind of blends in I ran it down into that vent put a few clamps on it so it’s secured nicely to the roof and then I finished up with some some of the self leveling a rubber roof sealant around the edges just to give it a nice finished look and I also put a couple clips here and there just to ensure that it stays securely fastened to the roof I love how this panel is flush mounted to the roof so from the ground you won’t even know it’s up here and I’ll have some ice or you know issue with wind or something rattling around on my roof so I’m really happy about the design and efficiency of this panel pretty cool you know taking a look at my number two battery here as you you may not know it but when might when I bought my coach it came with one battery so I installed a second battery the other ones on the other side of the RV so I got a little meter up here so you can see it’s teetering right between 12 point nine and 13 volts which is a pretty good charge so solar panel is working keeping my batteries topped off and and that’s a good feeling knowing that it’s not even plugged in to shore power the batteries are staying nice and topped off and nice and full so pretty cool so this project is all done I’m really happy with the way it turned out you know is actually a lot less complicated and a lot two went a lot smoother than I thought it would probably due to a lot of the planning I did making sure that I was doing the right thing so now I can’t wait to get out and do some do some boondocking and some camping in the Sun knowing that I won’t have to run my generator as much to keep my batteries charged up so if you want more information about this project and other projects is it RV with Tito calm and as always happy RVing everybody you

The importance of keeping your new panels clean at all times:
Power capability of a solar panel can be decreased up to 30 percent when it is dirty. So keeping them clean is very important to get maximum output. See manufacture’s website for tips on cleaning correctly to get years of service out of your panels.

But once they’ve reached their peak and start declining in output, most of the parts in solar panels can be recycled. Recycling includes semi conductor materials or glass and large amount of non ferrous and ferrous metals. Some private institutions and non profit organisations are currently involved in recycling operations of solar panels. Recycling possibilities will be based on what kind of modules is used that is silicon based modules or non silicon based modules.
