GreeSonic SunPower Semi Flexible Solar Panel 50W (ETFE+Fiberglass) Photovoltaic Solar Panel (Corrosion-resistant) with MC4 connectors

I spent a little more on this panel because it had the ETFE coating on top -- very similar to the UNI-Solar panels I've used in the past that stand up well in harsh environments. I've done some testing with this panel in various situations and have to say: it performs better than any other Mono Si based panel I've tried. It produces power in shade, it produces power when partially shaded and of course, it does great in full sun!I was going to install this permanently on a trailer, but I have been so impressed with how light and functional it is, I've decided to mount a PWM charge controller to the back with a long wire and universal two pole plug off that, so I can move it around my property and use it to charge all my various equipment batteries (that are never conveniently parked near power).I see these are not available right now -- I do hope the supplier gets more in stock. For their size and weight, you could find a lot of uses -- I'd buy another myself...

works great, it hasn't broke after 6 months of exposed to the sun every day, try 4 other brand before these, those all didn't last more then a month or week, what you pay is what you get.

I love the new material. It is like superman skin. Great output even on cloudy day!! Will buy more!!
