I've been playing with it on cloudy and sunny days in Canada and have been getting a charge. Bearing in mind that, with judicious use of the phone, one does not need to fully charge it every day. All one needs to do is charge the external battery and that will provide between 3- 6 charges of the phone (depending on the battery). So, you only need to acquire a full charge on the battery every 3-6 days... seems doable. added to that is the fact that you can bring a wall charger and take advantage of charges of opportunity when they are available. It's just that you do not need to depend on those opportunities.

I plan to strap it across the back of my rear panniers and go. The benefit of an external storage battery is that some devices will turn off and need to be rebooted if a shadow or cloud crosses the panels but not a storage battery so it is a bit of set and forget.

Here's my electronic array for the next tour (excluding the camera taking the picture).
