2PCS 100W 12V Flexible Solar Panel 9BB Monocrystalline Cell 12 Volt Semi-Flexible for Marine RV Trailer Boat Cabin Van Car Uneven Surfaces 12V 24V Battery Charge

I got a pair these on sale last year for $127 after tax. They work well and the pair puts out about 160w in good sunlight, as read on my power stations display. This is as good as can be expected from such panels. I just built a pvc frame/stand for them for an additional $22, so now I have 200w (spec) of portable solar panels for $150. This is far cheaper than purchasing a portable panel set from any of the manufacturers.

10 stars for these panels! We placed them on a sailboat to keep a lead acid battery set charged. They run a mini fridge, charge phones, run lights, charge computers, and run a depth sounder. They do all this and more. We trailer the boat with these in place on the stern pulpit, they handle interstate speeds and high winds with zero problems for the past year.1000% would buy again!

In California, even when the sun is at its brightest, I have never seen it reach 100W, at most around 70W.

I love these panels I have 8 of them now. They work great good output good connectors for mc4 easy to install anywhere

Muy buena calidad.

I like the flexible aspect, and the bubble texture seems to help some with light gathering from off angles. They're easy to hook up as they have the typical solar claw connectors, and some grommets in the corners to bungee or rope tie them to a roof on a camper or the like for short term use.The output is a bit underwhelming; on a 100+ degree cloudless day, noon to 1, on a flat vehicle roof, at 5k feet elevation, pointed straight at the sun, 75W each was all I could get out of them. They are more effective upside down or shaded than I expected, I do have to give credit where due on that aspect, they're still able to put out 10-20W in the shade, which is nice, but I was expecting a bit better than 75% of rated output in sun so bright I'd really rather not be tinkering with solar panels in it. I know many things are rated pretty optimistically, but I'm not sure how to go about getting more direct sunlight onto these panels than what I described.

I was excited to get these, I have used flexible solar panels for years on my sailboat. Some of my older panels got a bit worn out after 6 years so I decided to get some.new ones. Sometimes I lay the panels on my cushions while charging my 12 V house battery. This was the first time I set them out. Sunny day. I tried pulling them off the cushions and they had melted the vinyl and burned it. Do you know at what temperature vinyl burns? Melting is 212 F, burn is 736 F. So the little section on the panels (both panels did it) must have heated up to a temperature between 212 F and 736 F. That is a fire hazard and a design flaw. My cushions are $500 each to replace. I will refer their product to the authorities. It should be recalled as I was using it properly (both panels in series charging a 12 V lead acid battery with a tried and true mppt solar charge controller.

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!
