Both of my renogy semiflex 100w panels have quit.
The old thread on this subject appears closed so I couldnt add to that.
Renogy tried the alum backed idea and apparently that didnt work out. They have no semiflex panels available currently.
They expect a new version in the first quarter 2016.
They are providing me a full cash refund including return shipping.
Considering whether to buy something else or wait for the new renogy. I need the thin sizing.
That sucks...
I did try to warn folks about these cheap Chinese "knock offs" and was flamed pretty harshly for it. Sadly I was correct about the low quality..
While Renogy has decent customer service the products they sell are really of a low level and often don't meet spec. The issue has gotten so bad that eMarine just last week sent out a email with a video entitled "How To Test Your Solar Panel". They know a good opportunity when the see one and there is a huge one being created by companies who insist on selling cheap junk. eMarine is just doing their part to get everyone to actually test this substandard product so they can really see it for what it is.
For what they pay for the product, and what they sell it for, they are still making a big enough margin to absorb all the warranty issues. In decommissioning boats this fall I have had three boats with Renogy MC-4 connectors that literally crumbled when I tried to take them apart. Pure junk. Looks the same but NOT THE SAME!
The scary thing is they are still selling these panels out there and have issued no recall. I have a 50W Renogy semi-flexible out in my shop that is not meeting spec and it is only a month old. I plan to do a video with it to warn folks what to look for and how to test.
I would urge you to consider reputable and proven reliable brands like Solara, Gioco, Solbian or Aurinco..
