It'll be more than $25k. A battery alone is $10k, and a 10kw system is more than $25k.
Take a look at a year's worth of electricity bills to see what size you actually need to hit zero. Consider where a future EV fits in.
I was thinking I want just 4 or 5 kw of storage. Also wanting an electric car to plug in but that's another coat I'm not ready to dive into. Ugh.
Size refers to how many solar panels you have and their efficiency. Try https://sunroof.withgoogle.com but I think that site undersizes and expects you to pull some from the grid.
