So, not including the EV, what did it cost you to get up to the 90% of your current power usage?

Didn’t you just recently buy more batteries and another inverter?

[Tell It Right]

I'm going to say I would have spent another $25K (before the new 30% solar tax credit) to upgrade panels + inverter + battery storage to bring my throughput to 80-85% of my power usage (from the original 58.5%), but without the more I spent on solar equipment to account for also charging the EV.

The EV helps bring it from 80% to 90% by the simple fact that the EV doesn't have to be charged every day. Even though I don't use the EV's battery as part of my home battery storage, the EV's large battery capacity keeps it from usually demanding a charge on rainy days (letting me usually wait until a sunny day to charge it). Since the EV was always part of my Phase II upgrade strategy, I didn't do the math on how much solar equipment I would have added without an EV in mind.
