A few years ago Leia Media (Finland, country not very sunny) propused a ereader with a solar panel integrated... no like the one I propose but it was shown that a solar panel can provide enough energy to an ereader.

I think the problem is the cost. No more.

Cost wouldn't be a problem, but weight. You can buy a solar power bank for about $20, for example something like this:

Are you getting your money's worth? Absolutely not. Only useful if you are off grid for extended periods at a time. Takes about a week to recharge in the sun.
Imagine it on the back of the Note - when you are reading, it won't charge unless you lay on your back. At night when you sleep you cannot charge it. If you charge it during the day and read at night you will need a light which uses more energy. IMHO, it is better to have ereader and solar charger seperate, use both of them during the day (the Note doesn't even have a light) and charge ereader at night when needed.
