Because I'm retired, I have the advantage of charging my car in the afternoon on solar, so that helps with my bills. So, after a little over a year on Tesla Energy, my bills were $150 in the winter months (Jan and Feb) because my pool runs 24/7 when it is cold, $30 in March, <$5 until June, -$250 total for July to September, and $100 for the fall months. This winter has been similar, $150/month, but March bill should be very low because of warm weather since I don't need to run my pool at night.
I'm putting in a couple of more PWs because I want more hours of backup and I could sell more power if I had more stored in PWs during the summer months. I'm still not sure what caused the $1.00 per kWh today.
