We had a 240V outlet installed in our 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, although this figure is debatable. I know this because we debate it regularly :)
Update: Aug 27, 2025 - Jim suggests that we conduct our own 110V charging experiment which we'll start within 24 hours.
​
Also, Jim created a way to charge the car from excess power generated by our solar panels most of the time. The solution was called Suncatcher, but when Tesla changed the security requirements to access the APIs required to make Suncatcher work, Jim decided he wasn't willing to go through the effort required to regain access.

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%.
