Review: Still a great after 1 year of use - Its been 1 year and so far so good. I have 4 panels in a Series+Parallel config and I regularly get 300w, in rare cases have seen 330w, so 75-82w per panel. Can't complain about that! I also have 2 Renogy panels which perform at the same % of power under the same conditions. I worry about the longevity of these, as it appears that some cell clusters are darker/lighter when you view them at an angle (see picture). Maybe that's normal, or maybe there is some UV fading, only time will tell. But no drop in output yet. I like that these are low amp (6.6 Isc) so I can run them in parallel and stay under my 15A limit. Low Voc (18.6) means I can technically run 3 in series and stay under the 60V limit of my power station. I've tried running 3 in series (in hot weather, so not calculating for low-temp voltage) and they work but sometimes I've gotten nothing when I connect the wires, so I don't know if there was a bad connection or maybe the stated Voc is slightly higher and maxing out my unit. I need to figure that out as I might get 2 more panels and run a 3+3 S&P config. The weight and size to wattage ratio of these is excellent. I got them to go on my van conversion, but when I'm not traveling I take them off and put them on a homemade rack to offset my home electricity. This light weight setup means I can easily move them around the yard by hand to keep them pointed directly at the sun throughout the day. Good purchase and would buy again.
Review: Great panel -ordered more - Efficient panel at a great price, ordered more after initial installation. Paired it with Victron SmartSolar charger. Have not seen 100W; maximum observed output is 89W from any single panel. That said, this panel has a prismatic surface that appears to focus sunlight at lower angles. My observation is the overall output throughout the day seems better than my other ‘glass’ fixed panels because of this effect. Other points of note: Mounting eyelets ID is small. I needed to remove to use my preferred LOXX fasteners to mount. The wires exits the panel in opposite directions from the ‘box’ on the panel. For my installation this forced me to loop one wire under the panel so I could get both wires to run parallel to each other. Unsure of durability yet. I suspect UV will take its toll over the years but easy to replace as they are certainly priced right. Great value!

## Features

- Extremely Flexible: Update to latest version size: 36.22inch*23.22inch*0.11inch/920*590*3MM, The minimum radius of the arc that a 100 watts flexible solar panel can reach is 45cm (17.7 in). It is capable of meeting a wide range of applications where standard solar panels can be inconvenient to mount, suitable for off-grid applications that include trailers, marine, boats, cabins, tents, cars, trucks, yachts, RVs, campervans, caravans, sheds, residential rooftop, home garden outdoor, or any other irregular surface.
- Lightweight & Easy to Install: It is only 0.1 inches in height and weighs only 4.4LB (2KG), the solar panel is easy to transport, install, hang and remove. The metal pre-drilled holes and PV solar connectors help you install easily and quickly.
- 9 Busbars Solar Cell, High Conversion Efficiency: 9BB & A Grade Monocrystalline silicon solar cell provides high conversion efficiency up to 23%. The narrower busbar space and more cells receiving surface bring lower cost and increase the output of the PV module. Compared with 5BB panel, the 9BB solar panel ensures lower risks of microcracks and longer service life.
- Waterproof & Dustproof: This flexible solar panel is equipped with IP67-rated junction box to effectively block water splashes and dust from outside, making it perfect to be used outdoors. It is much more durable than traditional glass and aluminum model solar panels. 2 pieces bypass-diodes are built in the junction box.
- Excellent Quality: The flexible solar panel is made of ETFE material, which has a higher light transmission and longer service life than ordinary materials. The back panel is made of TPT, which is good for heat dissipation, waterproof, high temperature resistant and easy to clean.

Have 4 of these. Like these so far. Good output under ideal conditions. Are very susceptible to shading weakness however.
