That's what they are advertising at 30kWh/day. If you're extra conservative, they say you could even get a week out of it.
The reality is this, I have a 2300 sq ft home. I know that's on the low end of Paddock ballers. This is my previous year:
Divide all of those bars by 30 to get the daily average. I have a gas furnace in use during the winter. They are coming after natural gas too. It's already happening in parts of the country. Those bars will be larger than the summer months if I have an all electric house.
Which months will I be able to get three days worth of electricity from that battery? The months that I don't use heat or air.
Why would you think that electric will remain at eight cents? If you are at eight, then you have the cheapest energy in the country. How much extra demand has to be there before you no longer enjoy those rates?
How many electric vehicles equal the usage of one average home? Remember that the average home is that lowball 30 kWh/day. You stated that your personal usage was $30-40/month. At the rates you quoted, that would be ~10 kWh/day. Then, add at least two vehicles/ household.
Do you see how much additional pressure will be added to the grid?
I'm in Paducah, this is my current rate:
That rate doesn't include any taxes. At least the $8 gas includes the taxes.
We haven't had to ration energy in Kentucky, but those days are ahead. We haven't had a "please don't drive today because meemaw needs heat or a/c. It's coming.
A cousin out in Cali's rates:
Yep, low income folks are known for their capacity for socking away several thousand dollars for battery replacement.
