100W Solar Panel 12V, Flexible Solar Panel 100 Watt 22% High-Efficiency, 240° Ultra Lightweight Solar Panels for Marine RV Cabin Van Car Boat Camping Curve Surfaces, Black

The panels perform well seem durable and are flexible. I’m very pleased with them. They fit the bill for my application. Small amounts of shade do not seem to significantly impact the panels’ output, unlike some i’ve used. I needed low-profile flexible panels to fit on my truck’s topper, between the roof racks. The size of the panels are a perfect fit, and allow 2 to be installed on my roof. I wanted the installation to be easily removable, but to also easily handle highway speeds without me worrying about panels flying off. Utilizing the grommets on the panels allowed me to use M6 tee nuts and M6 machine screws and 1” M6 threaded plastic knobs to hold the panels in place. The grommet placement on the 2 panels I received were identical. I fit the machine screws through holes drilled in the topper. The screws (and large washers) are on the inside of the topper, with the tee nuts on the outside. The screws and nuts are snugly tightened, which allows the plastic knobs to be loosened and tightened without someone inside the topper holding a screwdriver to keep the screws from loosening. I used RTV to seal the holes, which also helps hold the screws and nuts in place without turning. I’ve used similar combos on truck toppers for 30+ years and have never had water leaks. I also attached heavy duty velcro around the edges of the panels, and attached velcro to the topper. The velcro alone holds the panels very well, but I wanted more security for highway speeds, hence the tee nuts and machine screws. I also put a “carbon fiber” looking vinyl wrap on the topper where the panels fit, for abrasion protection. Insulation can be placed under the panels to insulate the topper from the panels, which can get hot. 5 mm foam insulation is what I use.

This is the future of solar panels. I bought this to power a single lithium battery I use for a trolling motor. When wired correctly, it should provide enough energy to recharge the battery I use for my trolling motor.

I had a 100W solar panel on my camper but needed more power so i bought 3 of these & they matched perfectly! Great quality, works well, waterproof, easy to install, good value for money. Definitely recommend.

Open Voltage and short circuit current match specs. DVM showed 20.1V/6A on a mostly cloudy day. Fits perfectly in the spot I imagined keeping it. Other thoughts: Good thing this is a flexible panel as USPS tried to bend the box for me to prove it would flex.

Used for battery charging on boat, mounted to bimini top by installing grommets.

I’m out this on my RV and it worked out perfectly. It flexes nice with no cracking like some of the other Cheaper models.

The thermal expansion of ABS and twin-wall polycarbonate (~65–95 µm/m°C) is **3–6 times higher** than that of fiberglass backing (~10–20 µm/m°C) and **25 times higher** than the silicon cells (~2.6 µm/m°C). When designing a mounting system, this mismatch should be accounted for by using flexible adhesives, gaskets, or floating fasteners to prevent thermal stresses and warping. If these guidelines aren’t followed the solar panel will become wavy as is shown in the photos. This not only causes stress to the solar panel, the waviness allows the wind to get under the panel from the sides and can cause it to fail or rip loose from the fasteners.

Update: After less than a year of use both panels failed to produce even 40 watts of power between the 2. You can see in the pictures that's it's almost completely over cast today. The panel is Velcro to the top of my truck, it's 75F outside and I'm consistently getting between 30 to 45 watts power. Then the sun peaked out for a minute and I saw power above 120 watts! Holy crap. Lol. I'm blown away.... Plugged into a Delta 2. But this black, flexible, 100W panel.... Just unbelievable performance at far...
