Indeed. I bought the 26 Watt Brunton foldable which was mentioned here recently. I've been testing it by leaving it near a window all day. We've had very little sunlight. Some days it's produced only 60mAHrs of charge; at that rate it'd take a fortnight to charge some AAs.

This is in spring, where at my latitude we're getting around 13 hours of sunlight a day. It'd be worse in winter with around 7 hours per day.
