if you Google Grade B Solar Panels and then hit images, you will see examples. In the first 30 images they show, there are about 4 modules that are DEFFINATELY not B’s. The other 26 are.
However, 90% of all of the other modules shown after that are as well, I feel. So if you want to know what a Cosmetically Blemished module looks like, just look at Google Grade B Solar Panels. Because that’s the only difference between an A and a B.
Nevertheless, SUN guarantees Customer satisfaction on our Grade B, or “blems, as we call them, as well as for power output for 20 years. If you feel they are not acceptable, you can return them for a full refund or call me and we can work out a deal, so you can just keep them :). Really, that’s because Packaging and shipping are a drag and, especially, if you don’t have experience shipping big 3′ x 6′ sheets of glass around, right? And, like I just said, of course we provide a warranty for the output and lifetime of Our Grade B modules, Is there any reason why not ? We’ve sold hundreds of thousands of them over 20 years in the U.S.A., and around the world and basically, they just don’t come back.
After all, they’re solar panels, batteries that run off of sunlight, made of tempered glass, aluminum, plastic and rock. And besides, a warranty for any product, is only as good as its supplier. I’ve been alive, well and have survived in the solar and photovoltaic’s industry since I started the Tucson Energy Center in 1973. That’s back when Disco was big.
Do you know that if the US Government hadn’t blocked Chinese module imports I’d be selling you Grade B, discontinued, remnant , etc., etc. modules, from large 200+\w modules for $.30/w right now, and small 10+w modules for the same (think that would be $3/ea.) And, you know they’d be just about as good as any other brand’s grade A’s in the industry except, of course, SunPower’s. As many of you know, they have attained module conversation efficiencies from light to electricity of 20+%.
We need to bring in the Chinese again. They have something like 300 manufacturers, about half in the world.
It’s ironic that the company Solar World who lead the charge to eliminate them from America. It’s now the subject of industry rumors, they may close down. Business in Germany isn’t what it used to be., yeah they were German too.
You know I was happy to see Presifent Obama suppot solar so heavily but the mistakes they made in doing it left one stain on the concept of solar electric that won’t go away “Solyndra”, I hear it all the time still.
