I’m happy with the build quality of these panels but haven’t been real impressed with the output so far. Last week I was free camping and using this panel plus an older Ridge Ryder 150W solar blanket I inherited from my parents. Together (in series) they kept my Ecoflow Delta 1300 fully charged each day, but when experimenting with the panels individually, I couldn’t get more than 115W out of the Hard Korr, whilst the RR 150W right next to it was putting out about 120W. Same angle, same light conditions, and unfortunately same output despite the extra 50W rating.
Whilst it’s more practical than the RR blanket, I would have liked to see a higher output, especially given conditions were as close to perfect as you can get.
