9 - Full Months on Solar - Electric Vehicle Cost Per Mile

-

As of March 31th 

  • 18 Panels for a total of 5.76 KW
  • Installation costs of $16,468 tax 26% tax credit brings the net cost to $12,186
  • Break-even point is 10 years 3 months
  • 7.27% IRR
  • Lifetime energy in 6.35 MWh and $562 saved.
March was a great month for solar energy. With all the sunny days in March, I am now at 102% of project production. I even had a record day of 40.478 which beat out June and July. The 820 kWh produced in March covered 76% of my electrical needs including two electric cars. Overall since installation, the panels cover 50% of my electrical needs.

With solar how much does it cost to Drive my Tesla Model Y per mile?
  • My solar panels are estimated to generate 235,000 kWh in their 30 year lifetime at a cost of $12,363 that is a cost of 5.19 cents per kWh. 
  • My cost per kWh buying with the grid is 8.53 cents per kWh
  • The average cost is 6.36 cents per kWh since I get half from my own solar and half from the grid.
  • My Tesla is reporting 276 watt-hours per mile, let's add 10% for phantom drain and inverter efficiencies so 304 watt-hours per mile. 
  • .304 kWh per mile * 6.36 cents per kWh = 1.93 cents per mile
So 2 cents per mile! 

For reference, a 40 MPG car costs 7.125 cents per mile with gas costing $2.85 a gallon and you have to change the oil.

Solar Panels Installed and Operational

Yesterday we finally got our solar panels installed. The timing was great because today has been really sunny. It is like the sun is beaming me down money. The purpose of the solar panels are threefold, to save money, to help the environment (part of loving our neighbors), and to enjoy the technology.  Technical Specs of my solar panels  18 Panels for a total of 5.76 KW  This is 24 amps at 240 volts.  My Nissan Leaf has a max charge rate of 6.6 KW or 27.5 amps at 240 volts This should provide 2/3 of my electrical needs for the year.  18 Panels fit nicely on our south facing roof I can expand the system if I want. I might build a solar pergola in the future especially if we buy a second electric car. Ohio Power Solutions estimates the panels to produce 7972 kWh annually  Ohio Power Solutions installed the system in one day. Location I live in Xenia, Ohio. The math behind solar panels varies greatly by state, no only for the amount of sunshine but the wa...

8 Full Months with Solar Panels

I just closed out February and I thought I would provide an update on my solar panels. Here in Southwest Ohio, we had a period of 25 days of at least an inch of snow on the ground, the longest run since 1985. So I had several days with snow on my solar panels that did cut a bit into production but I still managed 355 kWh of the 380 I was projecting. I'm at 98% of the estimated production. I'll have to wait a full year for a full assessment. But so far I am very pleased.  18 Panels for a total of 5.76 KW Installation costs of $16,468 tax 26% tax credit brings the net cost to $12,363 Break-even point is now 10 years 3 months 7.26% IRR Lifetime energy in 5.49 MWh and $483.09 saved.
