Product Reviews

I will post more after I get some good sun here and do some load testing

This solar panel came to me misassembled, a diode in the termination box on the bottom of the panel had been installed backward shorting the output to .3 volts. I removed the diode and installed it in the correct orientation and now the panel seems to be working although I need to do further testing to see that its power output is reasonably close to manufacture specs. I felt they didn’t trust my measurement equipment (DVM) or my measurement technique and had I not had the know how to fix it I would never be able to convince them it needed to be replaced. I also have an issue with this termination box being located on the bottom of what is supposed to be a flush mount panel. I will post more after I get some good sun here and do some load testing.I bumped up the rating by a few stars because they refunded me 10% of the purchase price for the assembly error, and they assured me this was not going to happen again and I’m sure it won’t.I was able to get about 100 watts or about 5.4 Amps @ about 18.4 volts Using one meter to monitor current and another to monitor voltage, I used power resistors around 3 ohms for a load, and solar noon on a clear low or no smog day for my light source. I placed the solar panel on a sheet of plywood and oriented the solar panel for maximum power. This is not equivalent to what a test lab would do but it’s what I have on hand. One more note the termination box should be placed on the top or sun side of the panel so it will lay nice and flat on an RV roof as show in my last pictured, moving it there voided any warranty I might have had. See the new photo after 2 years of exposure to the sun and elements, on top is Kingsolar and bottom Grape Solar panle

Light, great for portable applications, versatile.

First, they failed to pack it properly so every corner was cracked and/or the eyelets bent. Fixable, but they really should pack it better.That said, I got 8 for a just under 1kW setup.The doors on the diode keep falling off so I needed a bit of glue, but it is just annoying.I love the longer cables. I can connect across longer distances and don’t need extensions.I used some zip-ties to create two fold-able groups of four.The set of 8 packs nicely and I can set up in a minute or two. Each side is about 20 pounds so I can easily carry them using two hands.I like the matte finish, but it does reflect more when off axis, but since they are light I can swivel them to point at the sun. I’m working on some racks to make this easy.Not optimizing, but just leaving them on my wall bent a bit, I get 880W on my MPPT unit at noon around the winter solstice, so I’m already at 110W/panel - it should be close to the rated things once I have them on proper racks.I’m using these with two large AGM 8A8D batteries in series, an MPPT http://www.amazon.com/Outback-Flexmax-Solar-Charge-Controller/dp/B008MOITL8/, An inverter http://www.amazon.com/Power-Bright-ML3500-24-3500-Inverter/dp/B000OS6UUM and Pyle 24-to-12 http://www.amazon.com/Pyle-PSWNV720-Power-Converter-Technology/dp/B003P17X8I , and a Grid Tie. http://www.amazon.com/Phonetone--buillding-Grid-tie-Inverter-Converter/dp/B00RX3YF12 and various cables, connectors, and wires.

So far it works great, even some output on a dark rainy day.

Update: 21-Sep-2016 all is well, over 30 days of camping use and worked excellent. Charges sunrise to sunset in any light and of course best in direct sunlight. Keeping it clean helps a little but really not much loss with light dusting. Snow (in July) was the only thing that slowed it down, wiped the snow off and it was back to charging like normal.—So far so good. The output is excellent, keeps the charge controller in charge mode during dark cloudy days, rain (heavy and light), and well past dusk (9:15 pm today 24-Jun-2016). Keep in mind that during these poor conditions it’s not providing much current, but it was enough to power two Maxxfan’s @30% without pulling from the battery. I have to say I’m pleasantly surprised by the performance in poor light and of course it provides full output as expected in direct sunlight.Some background: I purchased this to make a portable solar charging solution for our RV where I needed a very light panel as I wanted to be able to hang it on the front window awning (parked only) or use it on the ground with an extension when the awning was shaded. I used an aluminum frame to give the rigidity without adding a lot of weight. Panel and frame weigh <10lbs which is perfect.I did notice one thing that surprised me. When I covered the panel with a sheet of cardboard (to cut the power/charge) it actually still provided power. Sure it was substantially less, but not so low as to make the charge controller go off and the volt meter definitely showed the increase.

The weather in the PNW is crappy this time of year

Reviews that give 5 stars because their product (whatever it was) arrived quickly but hasn’t even been used or sometimes even unpacked drive me nuts !That said, we have lots of experience with solar panels. Our house has a grid tie solar system with backup,our boat has solar (these are to add to it) for many years. We’re going to remove a rigid 120 and replace it with 2 of these panels.The weather in the PNW is crappy this time of year, but I did get enough of a break in the weather to test the open circuit voltageand short circuit current of these panels.They came close to the listed numbers which isn’t bad when the sun’s only about 30 degrees off the horizon through some mist.I’m impressed with the construction, and the lighter weight. The weight savings is important on a multihull sailboat.EDIT: Early May and I FINALLY got them mounted.They perform as advertised. I saved about 4 lbs over the single 120 watt glass/rigid panel they replaced and got twice the power output !They DO expand with temps, so another post about being a bit flexible with mounting is good advice.Still 5 stars from me.

I would like to purchase a minimum of 6 additional panels

When they are available, I would like to purchase a minimum of 6 additional panels , with maximum of 14 additional panels, for my moving van modifications.

Great - when it worked

I ordered two of these for my boat. They are flexible as advertised. I used one for an offshore trip and failed in less than a month of use.

Not for long term installations

I have the 100 watt version of this flexible panel. After 7-8 months of installation the top clear coat has started to break down and start chipping away.

Was great for 3 days a month for 4 months…then NOTHING…it doesn’t work and amazon doesn’t make it easy to contact seller

Ordered if for my Father…he camps once a month…I bought it in March…he probably used it camping 3 total days a month…and now it’s June and it doesn’t work…

cheap connector ??

The connector did not work from the first try, when it snapped in – one side pushed out and one side pushed in. The second time I unplugged it and plugged it back in, it broke!

Three Stars

No issues so far

100w light weight panel

Will post more later, working out great, connectors are on back.

Before the panel looked great but now it has taken it’s toll

King Solar sent me a replacement panel. Thank you.UPDATEAfter 1.5 years of owning the 120W bendable solar panel, the protective coat on the outside of…

Excellent, picks up solar rays even when the sun isn’t shining really brightly. Use this when camping and it works well. I made a farm out of ¹⁄₂” pvc pipe that works well.
