We had a 240V outlet installed in the garage to enable faster charging than a standard 110V outlet would provide. (In hindsight, charging from the 110V outlet would have met our needs 98% of the time.)
​
Also, Jim has created away to charge the car from excess power generated by our solar panels most of the time. The solution is called Suncatcher, and he's happy to share it with others.

Daily Battery Status & Charging Costs
We're no longer tracking data at this level
We only have one car, so ...
- If battery is <50% in the evening, we charge to 50% (from grid) in case of emergency. 
- Unless we plan to travel, we limit daily charging to 65%.
