Renogy 160 Watt 12 Volt Extremely Flexible Monocrystalline Solar Panel - Ultra Lightweight, Ultra Thin, Up to 248 Degree Arc, for RV, Boats, Roofs, Uneven Surfaces

I initially gave this panel a five star review as it performed well upon installation.Now that its been on my RV roof for less than 4 months I have to revise that rating.The panel has stopped working. No output at all. The surface of the panel has delaminated from the substrate and watered has infiltrated & shorted out the underlying electronics or cells. This occurred on top of an RV where no one ever walks. How they could claim it can be glued to a boat & walked upon is beyond me. I tried in vain to contact Renogy without any success. I called Amazon & they arranged for me to receive a replacement panel without charge. Thank you Amazon.It is still left up to me to find a way to safely remove the glued down defective panel without ripping my rubber roof.I will install the replacement Renogy panel simply because I have no other option. I can't afford another type panel. I will never purchase anything else from Renogy simply because there is no customer service after the sale & the quality of their products is questionable.

Major quality issues. The panel fails after 1 week and literally falls apart. As you can see on the picture. Renogy Customer service is nonexistent. They simply ignore you and tell you that it is your own problem. I will simply recommend not to deal with this company at all.

I purchased two Renogy 100 watt Flexible panels to charge a Goal Zero Yeti 1000 solar generator. We live in Florida and experienced a glancing blow from Hurricane Irma last year that left us without power for a few days. Although my neighbors had gas generators, keeping them filled with gasoline was the big challenge.I have been running tests with my Renogy panels and Goal Zero generator that I use to power a mini freezer. So far it appears that we will be able to run the freezer by charging during the day and running the generator at night. We are hoping to be able to make ice for our coolers as well as some for various neighbors who don't have generators. ( Getting ice was the another challenge last year.) Of course the biggest mystery is, if we really get slammed with a direct hit will any of this matter anyways! (I'll get back to you if that happens, if I can!)But I really like the Renogy flexible panels for my purpose. I like that they are lightweight, easy to move and haul in and out of the house. I made frames for them out of small PVC pipes so that I can adjust them with the sun's movement. (By the way, if you purchase Renogy panels and extension cables, which you will need - buy 2 cables for each panel. To solar experts, that's probably obvious, but to the rest of us, not so much. Fortunately, I read an Amazon review and knew to do this.)Prior to purchasing, I emailed Renogy with a few questions and they were very good and generous with their time, info and patience. (I think their website needs to be a little less slick and more informative - my only complaint for Renogy.)Renogy has a good reputation and I will say these panels seem well built and substantial. Unfortunately I have had a little glitch with the Goal Zero (which is being replaced) so I had to curtail my tests. I was able to get 140 watts from my two 100 watt panels. I realize that you never get 200 watts from 200 watt panels, so I figured we were doing okay. If I find I do any better when my Goal Zero is replaced, I will add to this review.

This item has very poor quality control. I have 2 installed on my RV roof, and after 4 months, i noticed that my batteries werent charging fully even after an entire day of good sun. When they were brand new, I was typically getting about 250 watts between the 2 (160 x 2 = 320 watts) in the middle of may at high noon. So it could have been better, or worse. Well now after 4 months, I am lucky if I get 90 watts across the 2. This could be because, one of the panels could have completely stopped producing power. Which would make sense based on the time of the year of this review. It has developed these large white spots on the panel that look exactly like other reviewers have posted.Also, just and FYI. I have these installed with 3M VHB on the bottom and Eternabond on the top holding it down as a double safe measure, and I can say that given a few more months these would have flown off. These need gromet holes to be screwed down. However, I sure am glad that I didnt go the route of gluing and pouring self leveling sealant all over my roof, because then id never be able to get these off, which is what I am going to have to figure out how to do now(Update) - I wanted to make an update about the customer service of Renogy. I have contacted them many times over the phone, which is less than useless, as well as creating tickets online. It has been nearing a year, and still no response back from Renogy. This was something I was afraid of when ordering a product like this.

After installing two panel sets of another brand that eventually failed, I decided to try these on the roof of my Road Trek Van. So far, so good after two months in the hot sun. Voltage and current is what I would expect to charge/top-off the AGM house battery through a 20 acontroller. These panels appear to be better constructed than the ones they replace. Another plus is that they are close to the width of the old panels and I was able to use mirror holder brackets with rubber spacers to secure the panels with the same mounting holes I had used for the old panels.

We glued the flexible solar cell onto the top of our tent trailer and just got back from a week of off the grid camping. The 100 watt unit was more than adequate to keep our battery charged. We used an electric water pump, fan, lights and gas heater with a fan, and never saw our voltage drop over the week. This is an excellently constructed solar cell and performed as advertised.

Bought this to replace a Photonics Universe one that had failed. Immediately noticed the far better quality. Puts a good charge into the leisure battery even in low sunlight cloudy conditions. Mounted directly onto campervan roof using Sikaflex keeps my 110 leisure battery topped up .....in recent hot sunny weather I had fridge running together with inverter running fans and panel was putting out 18-20 volts. Extremely impressed and with the guarantee you can buy in confidence. Will be my first choice for my next camper project. 5 STARS

Der Artikel sollte besser beschreiben werden von Seiten des Herstellers, das Panel ist einwandfrei, solide Amerikanische Qualität, ich würde es immer wieder kaufen.update:Nach einem Monat im Gebrauch kann ich sagen das, das 160W Modul seine angegebene Leistung erreicht und ich endlich den Kompressor Kühlschrank immer anlassen kann.update nach einem Jahr:Panel immer noch wie neu 168 Watt Leistung sind nicht schlecht würde ich mir immer wieder kaufen.

They're quoting short-circuit current as standard output.The actual stats are well down even in direct sunlight.They may be honestly quoting output that is possible if you're literally baking alive on the equator at 50Centigrade under sun that would cook and egg in your hand, it's hard to tell fact from fiction.The holes on the side of the panel are put on by guessing and are all over the place - if you want to anchor two of these panels side by side using the fixing holes from both adjacent panels on the same bolt lug then forget it. I tried and failed as they were 7mm out in both the X and Y axis.For your money there are much better panels on the market, anything from LG for example - as LG are 'defacto' for a lot of home installations.However, if you must have low drag coefficient and/or curved surface mounting, then they are not the worst, but perhaps think about doubling your power estimates. Their claims of the coating (basically little pseudo microlenses bonded on the surface in a sheet) achieving higher performance when the panel isn't directly pointing at the sun are optimistic at best. If you didn't have the beads, the panel would probably work better when actually pointing at the sun.22% efficient conversion rate? Nah. No way in my optinion. The top panels on the market struggle to get anywhere near that, so there is no way they have achieved that in this form-factor.While I don't have sceintific measurement devices, I did a side-by-side comparison with my friends RV who came and parked next to me. He has two 'solid' 200watt LG panels, which wiped the floor with 4 of these 100watt ones.I would recomend just install them in series to multiply the voltages, and let the MPPT convert 'any' input voltage * amps, to your desired charge current.I get around 80 volts * 2.5 amps from 4 of these in series (reported by the MPPT), which the MPPT steps down to 24 volts * 7-10amps, to charge my 24 battery. (Usually it's around 2-4 amps in all but the strongest sunlight).Most battery chargers will be 6-10 amps, so this is a reasonably comparable output to a modest automotie battery charger?Configuring these panels in parallel will just give the MPPT more work to do, but if you had full parallel configuration (requiring loads more (and much thicker) wire and connectors on your vehicle roof), you'd get perhaps get a peak of 10 amps into 20 volts on the input to the MPPT, which would probaly convert it to 8 amps * 24 volts (in my case anyway, so pointless). Only get if you need bendy panels and double you calculated estimates. This company are just 'a-another' shady Chinese vendor with a very plausable, but ultimately non-existent UK office.When I ordered the panel, I got slapped with $40 import tax on top of this already grossly overpriced 'amazon prime' delivery, so factor that into your cost-benefit calculation.

Only thing I don’t like is the leads come out opposite sides rather than from one point. This made it more difficult to attach one of the leads to the roof so it doesn’t flap.I previously wrote this when I received the panel. We since travelled for 12,500 km throughout Alaska, the Yukon and B.C. in May and June with no issues. During August, I was on a weeklong trip in 30 to 34 degree weather and the panel which was siliconed directly to the roof started to delaminate. I taped the front edge and removed the panel once I got home and it was by then almost 1/3 delaminated. Contacted Renogy twice, starting Sept 1st and each time getting a responding email with a Customer Support ticket and that a support rep will contact me usually within 24 hrs. No contact and it now Sept 11th. Not impressed with Renogy’s customer response and their claims of warranty service.I have since built an elevated frame so any future flexible panel will have an air space underneath.

Not sure what went wrong here, but the panel I received was of exceptionally poor quality.Received well packaged, however for one the sealant job was poor (fixable), there was also sealant all over the surface of the panel (fixable), but then there was white globs all under the skin of the panel itself as shown in four of the pics attached, these were NOT on the surface. Alignment also seems off in places.Refunded, and Amazon collected free of charge next day.I'm sure Renogy are usually fine to go with, they have a good name to themselves, reviews seem very good, but personally I'm not prepared to order again and cross my fingers hoping I receive something decent.
