To put your numbers in perspective, I used to run my entire house on 3kWh per day. That included all my lighting, a laptop and satellite modem, stereo, fans for my heating system, but rarely TV (and fridge, oven and hot water were all gas).
As jhowell said, a Wysips panel could charge an e-reader around 10% in one hour of full sunlight. Well, I read a lot, and on an e-reader that's already been in use for two years (these batteries only tend to have about a three-year life span when used in phones—I'm not sure what the much slower discharge rates of an e-reader will do to their lifespan), I get more than a week out of a charge. So, I'd basically need to get about an hour of sunlight every day to make it worthwhile. otoh, I don't read it much outdoors!

More like seven hours sunlight per week, not necessarily continuous.
and not necessarily whilst reading.
Lying on the kitchen table in a sunbeam next to your car keys while you are doing the laundry or vacuuming could fit part of the bill. or sitting on the dashboard while you are driving.
If there are charging cells on the bezel I suspect clear TPU cases will be popular for this reader.
