That would only make you feel good. It would not make real change.
I'm frustrated that I want to get a full off the grid solar setup but then it'll cost 25K and won't really offset itself until 10 years or more. I'll feel good about being net zero in home energy usage but that is not a cost that the average person can afford.
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.
