[Speculation] Model 3 0.237 kwh/mile!

[JeffK]

Would you be willing to send me the particulars? I would like to see if I can help improve that bottom line.

Thank you kindly.

That's not to mention solar roof:

Note that mine says "net cost" and it doesn't factor in the fixed utility charges. Point being for me, there's no ROI in 30 years time.

Here's a previous bill:

This is also why a usage of 0.237 kWh / mi would be fantastic. I like to keep the bill low.

This is probably more helpful

Note the connection charge.

Solar would equal cost of solar + batteries + connection charge (recurring).
if I spent $20K on solar + $6.2k for powerwall + $0.8 for installation + $3.384k for connection charge over 30 years = $30.384k
This means for me to save money my average electricity bill would need to be over $84.4


I know there's a govt incentive at the moment, but still I'd barely break even in 30 years time.

You left out the time value of money. At 4% the cost of the system would be 52.2K or $145 per month.
