Is 83% of your home’s power being stored in batteries so you can use the power generated, or is it fed back into the power grid to take money off your bill?
Just curious.
I store in batteries. I only recently started selling power to the grid (since October) when my batteries are full. So I haven't put much onto the grid being fall and winter weather. And even then I make about 1/4th in cents/kWh that I pay for power when I need it. So I don't count putting power onto the grid as "storing it for myself for later". I count putting power onto the grid as a little gravy on top. The main financial benefit is from not needing to pull much power from the grid to begin with.
When I say 83% of my power is free it's from solar and batteries. I consumed 20,446kWh in power last year (how much power flowed through my electrical panels), but had to pull only 3,440kWh from the grid (16.8% of my power had to come from the grid). That's for an all-electric two-story home, charging the EV for 16K miles (not counting the 10K miles we charged the EV away from home on trips we made that had good charging options).
It doesn't save the world or anything like that. But it does give my wife and me a level of self-reliance we didn't have before. So the Dims' stupid energy policies have less control over us.
