We calculated we needed 19kW of solar to cover our annual energy needs (house and two cars). Turns out we needed about 11kW.
This is a part of your story I am not familiar with. Please tell more !
Thanks for asking!
When we were designing the system, we used calculations based on a well used model for a 2450 sq ft residential home, with two adult occupants. We added to that a calculation for our cars based on what we expected our annual mileage to be.
It turns out we use less energy for the house than the model calculated. However, the biggest difference was that we drive much less than we expected to.
As I recall, our combined mileage at our old place was about 30,000 miles/year. We estimated we would be driving 24,000 miles/year. Over three years we are averaging about 13,000 miles/year for both cars combined.
Then, to add to that, we traded in our cars for a pair of cars that are 20% and 30% more efficient.
No regrets though. The way I look at it we provide all the solar energy our cars, house, and neighbor’s house uses on an annual basis
