Topsolar Flexible Solar Panel 2pcs 100W 24V/12V Monocrystalline Bendable - 200 Watt 12Volt Semi-Flexible Mono Solar Panels Charger Off-Grid for RV Boat Cabin Van Car Uneven Surfaces

I have not used the panel yet and it is in storage. I can only inform that this item does look durable. Tho it has been in storage for over a year.

I purchased 4 of these 100 watt panels. When I first got these panels I tested them in direct sun on the grass right out of the box. 400 watts of panels only put out 210 watts. I was a little surprised I was only getting about 50% of what was advertised. However I justified my purchase based on the price. I was excited to get them installed on the van so I could keep my batteries topped off.Once they were installed I only got about 175 watt total out of the 4 panels. I assumed this loss was due to the fact that they are now installed and in the sun for more time. The heat I’m sure takes away from the efficiency.I’ve had them installed for about a month now. Today in full sun all 4 panels only put out 75 watts. That’s less than 25% of what was advertised after a very short amount of time.I justified the initial purchase because of the price. But if I’m getting less than 25% of what is advertised I should have bought one quality 100w panel at the same price and it would have taken up less space.They look great and I like the idea of solar. Unfortunately the quality of these panels are not good and are a bad way to spend your money.Would not buy again and would not recommend buying these panels.

I just got a set of these panels and connected them to my jump 1800 power station. They are producing a steady 70 plus watts each. I originally ordered the portable panels made by the same company as the power station. However at nearly $500 for the same amount of wattage, I was looking for a comparable alternative at a more affordable price. I purchased a different set that claimed 400 watts per panel. Unfortunately when I tested them , they we're only producing around 60 watts each. Back to Amazon they went and after more research I found these. You can't beat the price per watt, and they actually perform as promised! They also feel very sturdy and durable. I plan on leaving these outdoors in all weather conditions, which I found out after the fact, that the portable ones are not rated to do. Very happy with the performance. I like them so much I ordered two more right away. I now have double the wattage for less than half the price of the portable ones I had.

Good price and has been working all the time but it never produced 200w power.

They seem to be incredibly sensitive to heat, with power dropping to just 15w per panel under direct sunlight at noon - mostly defeating the point. I really like the design, but the panels are not effective even when freshly cleaned and under ideal circumstances. Perhaps mine are defective but I wouldn’t take a chance on another set, and instead I bought a more typically thick panel, which does the job far better.I don’t even want to resell these, given how weak the output is. Half tempted to just recycle them.

I have a 100ah LiFePo and this panel keeps it nicely topped off. Can't think of anything to complain about. It very affordable. Very flexible. And was giving me a bit more juice than the same rating portable folding solar panels.

Bought these during Amazon's Prime days for a good deal. Would have been very annoyed if I had paid full price. Installed them on top of a a fairly taut mesh shade sail with zip ties in the backyard. The panels backsides stay as cool as possible, with this set-up. At mid-day, with zero clouds and the blazing Florida sun, I get 96-98 watts with the pair of "100 watt" flexible panels, so a hair under 50% efficiency. If I hadn't gone to all the trouble of setting them up, I would have returned them. The silicone caulking job where the cables go into it was incredibly sloppy, to boot. Didn't trust them to be weather proof, so I added some butyl sealant. Wish I had gone with the pricier Renogy panels. You get what you pay for.

Be careful with the panel install it on a flat surface it can have a slight curve to it but be careful. The panel is very very delicate keep it in the box until you are ready to install and slide it out carefully. In Florida sun I was getting 81 watts before I broke it with the panel just sitting on the top of my Jeep the photos show the panel trying charging a Jackery 500 that is connected to a refrigerator after I broke the panel as you can see it’s not keeping up when the compressor runs. How I broke the panel. I was keeping the panel in the back of my Jeep so when I went to the beach I could just throw the panel on the roof and the sun would charge the Jackery 500 and the Jackery would run the refrigerator sounds good enough wrong! Whe I took the panel out of the Jeep holding the panel with two hands I heard this crunching sound I said what’s that sound it sounds like Rice Krispies or very very thin piece of glass cracking. That’s the sound that the panel makes when it is breaking I went from 81 watts to what the display shows in the photos to at best 6 watts to the trash can. It just got progressively worse after I broke it! So be careful flexible does not mean durable it’s not something that you can just keep in the car and throw on the roof and then throw it back in the car it has to be installed supported from below nice flat surface but basically it’s a permanent thing. Just keep it in the box until you are ready to slide it out onto the surface that it will be installed on.
