Solar energy & Grid energy

I'm designing an app that shows the incoming solar energy and the energy usage from the energy grid.

The goal of the app is to help people to use most of the solar power.

If the user drags the sun in the upper-left corner down, the solar forecast will appear. That way, people can plan high energy consuming tasks on hours with the most solar activity.

Feedback is much appreciated, because I'm still in progress! :-)
