Renogy SunPower Flexible 100 Watt Monocrystalline Solar Panel

I received this panel a few weeks ago. Box showed no signs of damage. There were a variety of scratches (not really worried about this as these panels scratch very easily). The issue is the prominent dent in the solar cell (it actually protrudes through the back). When provided this image to the seller, I was told this is normal and would not effect panel performance. I've had solar for 8 years and didn't find this an acceptable answer (this cell will definitely suffer from microfractures and will eventually fail). The sellers solution to this was to send back when it failed during the 2 year warranty window (this panel has a 5 year warranty). No discussion of what constituted "failed". Originally I was going to have to ship the return at my cost, but through some pushing through Amazon the seller agreed to pay for return shipping and would replace. I didn't want the hassle and chose to assume the risk on this and chock up to experience. I spoke with a different supplier in Canada and they had seen the same problem with a certain lot of these panels (seconds perhaps?). This seller said they would ensure not to ship damaged panels and would warranty for the full 5 years. I would advise against buying these panels unless you can see them first hand or have a hassle free return policy. I called Sunpower and they do not deal with customer concerns anymore and seem to push this off to the resellers. They seem to be getting out of small solar, which is unfortunate because they had a good product.

These panels put out good power for sure but among several other thin film panels I have, these are by far the easiest to clean. These have a nice smooth finish to the exterior. They almost never get dirtier than the thinnest film of dust and a quick wipe or squeegee is all they need to be spotless again. The textured coating of other flexible panels may be great when they’re brand new, but they trap more dust as well and need to be sprayed down more heavily to remove the dirt. Great product.

Très satisfaite Bien emballé et bon rendement

I used these to replace 2, 100 watt panels that failed after five years glued on top of my class b van. They work well charging my 300 amp hours of lipo4s. What a pain getting the old ones off, sticky mess. I used 3 thin strips of heavy duty 3m tape on each panel this time and screwed them down with the holes, and 2 inch rv roof tape around all edges. 80 mph down the highway after 2000 miles no issues so far. Flexible glued panels in general only last 2 to 5 years versus glass panels with full air flow underneith. These work great, pushing up to 9 amps in full sun in a series configuration. Hopefully they last more than 5 years this time, we will see.

The cords aren't long enough to mount on a roof of an rv
