I’m guessing a 7KW system will do it. There are a lot of variables to the system cost.
Panel type. Conerter type. Install. For us, the differnce between a small system and the big system was literally, just the cost of the panels. Up to our 7.5, its the same converter components. Adding panels is a couple hours install above the smaller count panels. Labor, electrician basically will charge you the cost of the day the work is all sub day. It’s still a multiday job, but each step takes a day.
Overall, don’t know where the rebates are at now. Don’t know the tax story now.
Gross cost of the system will be akin to buying an SUV before tax/rebates.
Financially in the near term, not cost efficient for us, I’m looking long term and expect electric rates in California to get ugly.
However, from first hand experience. Watching the meter spin backward, puts a smile on your face.
