Topsolar 180W Semi-Flexible Monocrystalline Solar Panel Charger Off-Grid for RV Boat Cabin Van Car Uneven Surfaces

I am very pleased with this TP Solar panel and recommend it over even more expensive options. I am using it to charge two group 24 gel house batteries in my teardrop-style camper when off-grid camping, which power lighting, ventilation and a 12v freezer. The flexible panel stores neatly under my mattress, keeping it safe under all conditions when not in use, such as traveling or sleeping. It is way more powerful dollar-for-dollar @100w and easier to store than a suitcase type of panel. Plus this one can be deployed in a myriad of different ways to suit conditions.In regard to another review here complaining about output voltage and amperage, it is really all determined by the controller you use. I chose a high-quality mppt controller which cost as much as this panel: https://www.amazon.com/Victron-SmartSolar-Charge-Controller-Bluetooth/dp/B075NQQRPD . A quality controller like this easily converts excess voltage into more amperage, putting more amps into my 12v batteries than the amperage produced by the panel. This investment also gets the very most out of this panel in cloudy or partially shaded conditions. $20 charge controllers are $20 for a reason...you get what you pay for and you will NEVER get the most out of any panel with a cheap PWM controller. My $0.02 says to go cheap on the panel(s) and spend your money on a good controller which will squeeze every last drop of energy out of any PV arrangement you deploy.Thank you for reading my review.

Works great, smooth surface, could easily be mounted with gorilla tape only.

Less than a month after install I had a failure with an overcurrent condition on my power system that caused a loss of power. I'm lucky the system I use has proper protective systems or this failure could have been very costly. I have 3 top solar panels hooked up in this system(wired in series) and the other panels are working fine AFTER removing this panel from the circuit. The panel in the picture was the cause of the failure, I had to rewire my system and I will now need to uninstall this panel and install a replacement. There is no other damage showing on the other panels, and we hadn't had hail in months so I'm pretty sure this is some kind of manufacturing/product failure.

I don't know about tech support I haven't used it. It's charging LiPo battery up with out a problem today. I have not mounted it yet so it's being used as a portable panel until I get it mounted and a second one. Maybe third one, I'm planning on having two or three mounted on my vehicle roof to charge a "LiPo house battery". I'm thinking about getting a few more for my RV roof too, I might be able to mount 3 on it too. But I will need another controller and to relocate and change battery type in RV. I will try to update after more use.As of 8 April 22 the panel is still working very well for me, I upgraded the solar charger andmounted on roof rack of my Jeep. I'm thinking about ordering two more still. I've upgraded my storage battery and the company recommends 300 watts of solar power to charge it. So I do need them.Update 4 June 22: I've removed it from the original mounted location to use as a portable panel (I've framed it in light weight aluminum) that makes it easy to move around to track the sun. In my use with air gap from surface it's regularly out performing the 100w rating in less than ideal sunlight even. I highly recommend this panel and would have bought 2 or more. If I didn't find a pair of rigid 100w panels to try at lower cost (after adding my cost for aluminum to frame for mounting). Light weight, still has good output when part of panel is blocked from full sunlight and at less than ideal angle to sunlight, plus is hasn't been damaged by cats wanting to walk or lay on it.Now if I could get as lucky buying a lottery tickets as I've been with this panel.Update on the solar panel: I had used it for short time as a portable panel and found the ridge panel that I replaced it with higher capacity didn't perform as well. So I ordered a second one and now have both mounted. I highly recommend them, especially if you are going to mount them where they will not always be in ideal condition for best performance.27 Apr. 2023: update on the 2 100w panels both are working fine still, I'm ordering a few more. I have nothing bad to say about them, I'm adding 3 pictures to my review, the 3rd is showing the current charging from the 2 panels. It's a overcast rainy "day 2" of it, the battery is running a fridge freezer that I bought on Amazon a couple years ago. If I have 5 plus days of overcast/ cloudy weather (fall or winter "less daylight" ) the 100 amp LiPo battery can get discharged to point of shut down. The system I've got setup charges the "house" battery with the 2 100w panels first then adds to vehicle batteries secondary. On that subject my vehicle hasn't been started in over 4-5 days, but it has it's own solar system on it too. A stand alone 85w system.19 Aug. 2024A update on the 3rd panel I ordered, I've had it in the box unused until now. I removed it from the packaging that is of sufficient quality to provide protection in shipping and storage, as the previous one too. This one is not up to the same standard as the first 2 I bought (in my opinion) the sealing of the wires appears to be white caulk now, and not as good sealing the control box and wires. I would guess this is done to reduce costs in manufacturing. So I made a light duty frame (photo # 5) for it and pop riveted the wires on and will be sealing it myself. Photo #4 this one is the starter for my Scamp T.T. I was planning on doing 4 100 w panels for it as portable since I don't want to drill holes in the fiberglass shell, plus the ability to place for best sunlight exposure. Now I need to install the solar charger controller to hook the panel up.Note on my original 2 that are still performing very good, to the point I hardly ever need to check on it. So I still will leave it at 4 stars rating, other than the change of sealing compound I would have upped the rating to 5 stars. I would have paid $5.00 more for the same quality as the first 2 I bought.

Great panels so far. I am planning on installing these to the garden bed net arc. Tested it by installing them on the south side of the home. Connected in parallel, the output ranges from 268 to 299 watts.Great 360 watt panel!!

These panels are a buy. I purchased the first two 180 watt units after careful research and added two more 3 months later once I saw how well they performed. I'll get more. Excellent build quality at a decent price.

I bought one of these and used it all summer long in my '85 Vanagon. Combined with a Renology charge controller and a LiFePO4 house battery, I had more power than I could use. While hosting a remote campground in the Redwoods National Park, I was able to run the park radio, all my lights, stereo, laptop, and keep my phone charged even over short periods (up to 48 hrs) of cloudy weather. I did add a 15' extension cord so that I could keep the panel in the sun no matter how the van was parked.Additional Info...The panel still works great after two years but I have found that 100 Watts is not enough to keep my battery charged up if overcast / cloudy condition persists for more than 48 hrs. So I've upgraded to 200 Watts (two panels) and am going to see how well they do.
