I've been using this panel for just over 5 months, I wanted to see how it performed in the winter and then spring, I'm impressed.
I've had products from Renogy before, & the only reason I bought this was because my older one got damaged by a freak wind event.
In comparison with the old one (which was good) this thing is impressive.
I have had out of it 202w, yes that's correct 202w, a solar panel that delivers full wattage +. In general spring sun it's regularly pushing out around 120-180w. Overcast days around 50-120w. In dull winter days full of cloud it still somehow produces wattage, enough to charge a phone.
I'm very impressed with this panel & highly recommend it, if in doubt, I wouldn't be, it's worth the buy.
