Three hours of sun and my curtain's battery basically never dips below 80% now, even on cloudy days it keeps trickling in enough to matter. The low-light boost is the real deal, I've only had to plug it in once since setup.

I was skeptical about the efficiency claim, but after a week it actually keeps my curtain motor topped up even on overcast days. Three hours of morning sun is enough to get through the whole day, and my energy bill is a little lighter too.

My curtain robot used to die by mid-afternoon on cloudy days, now it's still going strong at 9pm even with just a few hours of weak morning sun hitting the panel. That low-light boost is the real selling point, and it's noticeably cut how often I'm pulling it off the rail to recharge.
