Actually, I've been thinking about getting rid of the battery.

The actuator motor doesn't use a lot of power, and if the sun is bright,
the little 10w PV can move the array.
So, If I was to stick another 10w PV up there, I think it would track,
anytime the sun was pretty bright.

But, the main drawback is the Go-Home after sunset mode.. It needs juice!
