Accountant members here learn more than they contribute. Allow me to point out one gotcha in the 30% US federal tax credit for solar energy systems: Credit is not allowed for equipment used to heat swimming pools or hot tubs. So you may want to think about the hot tub heater.

Anyway, I was wondering, is it easier to track the sun with a light sensor, or is it easier to just do a timer that takes it east to west during the day and resets after dark? Just seems that a timer would eliminate the hazy/cloudy day problems with light sensing.
