My monthly electric bill with solar

Recommended Posts

My Tesla solar panels and Powerwall were installed on March 6th and I was able to activate them on April 27th, though something was misconfigured with the Powerwall so it was off until Tesla came back out on May 2nd.

 

When I blogged about my first bill with solar I didn't know which bill to compare it with, so I'd listed 2 old bills for comparison. This morning I found an electric bill from last year and can see the meter reading date is the same, so was able to match the bills up correctly for comparison:

 

  • $73 for May, was $130 last year
  • $35 for June, was $180 last year


Note that solar was only active for half of May's bill.

That's great!  Are you satisfied with those results?

 

I'd really love to get a ton of solar panels and two PowerWalls. :D  We lost power again two weeks ago during a strong thunderstorm and power was off for hours..

0.073$/kWh? 

 

You would be even more happy if your bills would be based on German electricity costs (~0.31$/kWh for green power). 😄

Very happy, though I think 2 Powerwalls would have been better.  My understanding is I can get the federal tax credit for it if I also install at least 1 panel with it. It looks like there's room at the top of the west slope for another panel, possible 2.

I'm going to wait until next year though, then check in with Tesla to see what can be done.   I think they can mount a second Powerwall on top of the first or

It's 0.112 with the grid fees (34.98 / (657 - 345)), which is a little higher than the $0.1098 I was paying with the "free nights" plan, which I found to be rather inconvenient as I stopped doing laundry and dishes during the day (as the rate was $0.2664) and became continually backlogged on laundry.

 

This does mean the break-even point is longer than elsewhere.  A rough workup for that is:

  • $20769 for solar (after tax credit) w/out Powerwall
  • $2000 a year for electric, solar sized to cover 90%
  • $1475 a year savings for gas
  • $582 a year home insurance increase

20679 / ((2000 * .9) + 1475 - 582) = 7.7 years.

If I add the Powerwall its $28401, or 10.5 years.

I'm paying even more than that.  My latest electricity bill was $320.  I'll go take a look at it later to see what I'm paying per kWh.

I installed solar panels on my house a couple of months ago.  My bill has already gone down from $200/month to about $35 and that's only because I have to pay for some insurances for plumbing and electrial through my FPL bill.  :)
