Newpowa 75W Mono/Poly Solar Panel (75W Poly)

This panel is well built and works as specified. I mounted it under my roof rack using a stainless steel drawer slider. I bought the 75 Watt panel because it was the only one that would fit in between the cross bars under my roof rack. I designed a custom cable on-line and plug it directly into my Yeti gold zero 1000. At 10,000 feet, I get 10 to 12 more watts out of the panel than my Dometic cooler draws when the compressor comes on. So during the day, I'm getting a net charge increase to my gold zero.

I actually bought the 70W panel, but it no longer exists on Amazon so they won’t let me write a review. 70W. It is charging at 8.1W in direct sunlight properly aimed in California. I added a second battery, does not provide any more charging. Bought a cheap 29W which works better. Tried 2 charge controllers no difference. Won’t buy again.
