Apparently it charges a battery for night flight (9/17). Imagine if they were only flown during the day, and that extra energy was put back into the grid.

It not only charges the batteries during sunlight hours but also gains height to take advantage of potential energy during the sunless hours.

Turned around by bad weather, regrouping in Japan. http://www.bbc.com/news/science-environment-32993127

 

It's a six day flight, and they have reliable and sufficiently accurate weather forecasting for three days only - so there's a risk even with good initial conditions.
