Renogy Flexible Solar Panel FAIL

I installed one Renogy 160 watt flexible solar panel on my RV roof less than four months ago.
These flexible frameless panels are designed to be glued down. They are laminated and designed for the harshest environments....or so the company states.
They even advertise them to be glued to the decks of boats & even walked upon.
The panel worked great until yesterday when I discovered it was no longer outputting any voltage.
An inspection of the panel on the roof of my RV showed extensive delamination and water infiltration between the laminations which obviously shorted out the underlying cells & circuitry.
I have tried in vain to contact Renogy CS without any success. I called Amazon today and they said I was beyond the 30 day return period by 3 weeks. Fine. I only called hoping they had a Renogy CS contact.
They did try to contact Renogy to no avail.

Long story short, they elevated this issue up the chain and stood behind their sale & are shipping me a replacement panel. Kudos to Amazon.....and a big thumbs down to Renogy, who obviously doesn't support their customers.
For a $250 issue they won't be getting any of my future business.
Unfortunately, I'm left with having to somehow remove the defective panel from the roof without damaging the rubber and I'm still in the hole for $50 worth of new adhesive for the replacement panel.
But it could have been worse.

I don't think the flexible glue on panels are a good idea. Panels work better with ventilation between the panel and the roof. This keeps them cooler and helps with efficiency. I used 3 inch high stainless steel Z brackets to allow for more allow flow under my panels.

Point well taken.
I was trying to avoid holes in the membrane.
When I saw these panels I was seduced by their marketing claims.
Live and learn I suppose.

Thanks for responding.

I have 2 100w Flex Panels from a lesser company have had them since november and they still work fine no delamination, and they are Screwed straight to the roof of my rig as the instructions said to place flat with no space underneath for proper installation. Renogy is a Big name company and i have heard very good things, However there are always defective products also beware on amazon what you buy is not always what you get , often you will have chinese manufacturers labeling their products as a major brand and selling them through straw sellers on amazon, you think you got a genuine product but you got a knockoff, Amazon Is not going to verify the authenticity of products from a users inventory shipped their warehouses to be sold by their users, they have their rules and whatnot but you are buying from a 3rd party amazon just provides the platform much as ebay so you never know what you are truly getting.


Side note The renogy 160w Flex Panel is $300 Direct from Renogy, Some one selling it for $50 less is most likely either selling a counterfeit Or older revision/Discontinued panel that has been sitting for a long time in who knows what environment or was discontinued due to design flaws

Thanks. I tried contacting their CS people. All I could get through to were sales & tech support. Amazon tried as well while I was on the phone with them. I guess Renogy was having a bad two days because no one was available to talk to me or Amazon.


Regards

I paid $250 four months ago. It can be had for $225 now. Mine is genuine Renogy... albeit a genuine piece of Renogy junk.

The only case where I'd use flexible solar panels is on a curved surface where there is no way to mount a fixed panel.



Look at you RV roof and guess how many screws and holes are already up there. Getting a good seal on a Z mount is simple with a self leveling sealant like Dicore.


Others have already made important points.


Good luck...

Have no idea of the quality of the newer Renogy panels, but bought 12 100 watt panels about 8 years ago for $200+ each. After less than a year, panels became yellowed and cloudy, and production dropped to about 50%.

I don't think I would install the replacement panel with glue. There is a fair chance it may fail in four months also.

The panel didn't come with any frame or holes & was designed to be glued or taped down.
However, my new (replacement) panel arrived today and this panel is the same except it has holes with brass grommets around the edges. So, yes, I'll be investigating another method of attachment that doesn't involve gluing OR making additional holes in my roof membrane. Not sure how I'll do that yet, but I'll figure it out.

I too did not want to use screws, Used VHB tape and had no problems.
