If you are charging your ev at home you need to switch plans. Also even though you have solar is it sized to your usage? You also moved in during months solar doesn’t produce as much unlike the spring and summer. My solar system is oversized for my usage. Purposely went with 20 panels assuming we were getting an ev at some point. Due to this I think the only month I might get an electric bill is December cause of all the Xmas lights I put up.
