Uni-Solar PVL-136 PowerBond PVL 136 Watt 24 Volt 216-Inch x 15.5-Inch Flexible Solar Panel

I just bought number three. Unbeatable price-per-watt and impressive low-light output, better than any other panels I've worked with. Several years ago, a snow storm knocked out our electricity for 8 days, so I have them for emergency preparedness, and made a few changes. Peeled off the adhesive on the back of the panels (along with several layers of skin at the same time), attached Anderson PowerPoles and made a mounting frame on my shed in the back yard. On normal days, they recharge the batteries for the lighting in my back yard (want to do more, just need the time). The adhesive goo from the back of the panels works great to weatherproof the PowerPole connections and short-circuit proof the battery connections. They roll up and nicely fit in a 5 gallon bucket for easy transport (one panel, one charge controller and a couple of connecting cables per bucket). Don't even think about keeping them portable with the goo on the back. It's some seriously sticky stuff once it gets even a little warm.I unrolled them on a grassy area during field day last year. The two panels and two marine deep-cycle batteries ran two radios all weekend, pulling from the batteries overnight. One panel and battery could have easily ran three radios without breaking a sweat during the day. I'm a little worried about rolling/unrolling in the cold, but am only really worried about them getting stepped on since they're built stronger than I expected for a stick-on-and-leave solar panel.***THESE ARE 24V PANELS! MAKE SURE YOU USE AN APPROPRIATE CHARGE CONTROLLER!

only gripe is 24 volt panel order outputs 46.7 volts open circuit voltage in sunlight. Some 24 volt controllers won't like it. I got 24volt panels because 12 volt chargers want at least 18 volt panels to keep charging under low light conditions. Not exactly what I wanted. THESE ARE 48 VOLT PANELS WHEN LISTED AS 24VOLT. They will charge a 24 volt system at dusk and dawn though, and any decent charge controller will accept the 48 volt output they give under full sunlight...

Seems like a very durable product. However, taking off the adhesive backing was a bear. My son and I spent over an hour removing the backing inches at a time. Almost gave up as soon as I started but there was no turning back as soon as the first foot of product was laid down. Glad I hung in there because it really is a nice panel. Hooked it up to a voltage tester and it registered 41.6 volts. Product should last longer than the RV roof it is attached to. Overall, I am very pleased with this product. Just wish the installation was a little easier.

Great panel and great price. I installed 2 of these on the top of my trailer and they really generate the juice. I highly recommend these, you clean the area where you want to install the panel, roll it out to make sure you have it in position, pull the paper backing off the underside of the panel and push the panel down on the surface and your done. Takes about 10-15 minutes at most to install.

I wanted to help my sister after Hurricane Maria. It has been over 6 months that she has not had power. I put together a system that I could order from Amazon and send most of the components to Puerto Rico directly. I ordered the SolarEpic 40A MPPT Solar Charge Controller, four Uni-Solar PVL-136 PowerBond PVL 136 Watt Flexible Solar Panels, a POTEK 2000W Power Inverter Three AC Outlets 12V DC to 110V AC and the miscellaneous cables and fuses. I prewired the controller and the inverter and wrote a detailed set of instructions on how to connect everything else. Luckily, I found in PR the batteries at Batteries Plus, and I ended up using two 12 vdc 155 Amp-hours for the project. My sister and my nephew installed the system 03/03/2018 and it has been powering her fridge, a few LED lights, a fan and charging phones and computers since with no problems. These products are outstanding and provide very impressive performance.

The unfortunate thing is that Uni-Solar has gone bankrupt, so the remaining panels are rests of stocks, meaning you have to pick-up whatever you can.I bought four of these panels to use on my RV (which has a curved roof), and they indeed followed the curve perfectly.The problem is the gluing: Removing the white protection sheet that covers the bonding black goo is easy enough, but don't even think about removing the velcro strips: You can remove the black fabric strip of the velcro, but the velcro teeth plastic bands are bonded to the panels and virtually impossible to remove: After half an hour trying to unglue a 10 centimeter long section of it we finally decided to leave it and use some black goo glue thingy on them instead of trying to get them out.The result is that we have very slim panels in the center, with bumps on the side.If you can, try to get the models without the velcro padsAs for the power, they are not yet connected to my charge controller, but I measured the tension on each of them with a multi meter and they indeed deliver current, even when partly occluded or still rolled in the box!

Initially I was upset trying to install these because the backing paper was tearing-Once I figured out how to get it off they mounted easy and so far work great-Will be taking RV out for 10 day fry trip so I'll see how batteries hold up. Can't beat the price though there is no warranty since company is out of business.
