Solar In Dublin Electric Vehicles

EV RATE PLAN Facts…

image17

Public demand for power is greatest between 3PM-9PM... 

7 a.m. to Midnight is cheapest on weekdays. This rate plan may be best for you. Single meter for your home and EV charging. The price per kilowatt-hour varies depending on the time. On most days, charging during peak hours is unnecessary. If you are driving more on a particular day, your real cost will only be the wholesale cost which is usually 10-20 cents on a loan. This includes interest.


Solar allows us to sell high and buy back low. 

* 2019 worst case scenario=

  1. Sell for as much as 47 cents per kWh
  2. Buy back for 16
  3. Keep Smiling


No more unwanted surprises...

We bank electricity into PG&E grid from 7AM-9PM weekdays. This is when the sun is shining and electricity rates are always higher than unusual for most rate payers.. 


***  Less than 17 per cents kWh is our net buy back rate between Midnight-7AM. 

This includes 2 cents for NEM2 Non-Bypassable Charges


If you DO NOT charge your EV at home, solar + EV Rate Plan is mathematically and factually advantageous:

  1. Typical Savings is over 30% immediately before selling at a profit
  2. SELL HIGH!!!  47 cents+ per kWh is without solar peak hours what we would have paid. We SELL AT THIS RATE when we over-produce during sun hours.
  3. We buy it back cheap. This is in the nighttime or winter when rates are lower.

*2 cents a kW NEM 2.0 with PG&E

  • Even if you DO NOT charge your EV at home, solar + EV Rate Plan is a huge advantage.
  • RATES CHANGE RAPIDLY
  • Grid electricity rates are higher in Summer than Winter.
  • 30 cents/kWh will be close to an average credit for solar electricity sent to grid in summer. 
  • In Off peak hours, on weekdays, solar is not producing. We buy electricity at night cheaper.
  • Daytime electricity will generally speaking, return 2 for 1 kilowatt hours between 11PM-7AM. 
  • We produce the electricity in the summer when its worth more and buy it back in the winter cheaper.
  • On PG&E's residential EV rate plans, customers pay the equivalent of $1.20 per gallon to charge their vehicle overnight.
  • Those without solar may not benefit at all or possibly pay more with EV Rate Plan
  • BUY LOW. SELL HIGH. BUY BACK LOWER 
  • Summer sunny day energy is more expensive
  • Night time less expensive
  • Winter even cheaper

Time Of Use + Solar = $


  • In Peak hours, we buy or sell electricity for 51 cents per unit in the months of May through October with EV Rate Plan. Without solar, you will pay 51 cents to PG&E instead of much closer to off peak rates, as a solar wholesaler.

Time Of Use EV Rate Plan: 

Energy produced  from solar is typically FAR LESS COSTLY 

than renting electricity from a 100 years old grid. 



  • Solar array is designed to overproduce during the daytime in summer. 

Buy the energy back cheaper at night or winter.


SELL HIGH and BUY BACK LOW:

  1. We do not produce electricity at night, so we buy back from grid when rates are lower.
  2. In the winter, we produce a fraction of what is produced in summer. We buy back from grid when rates are lower in winter.

  • Most, if not, all energy consumed during the daytime hours will direct from the sun. This is from solar instead of the 28 or 51 cents we would have paid for the hodgepodge of nuclear/coal/hydro, etc.. without solar.
  • In summer, our night time energy is purchased back from the grid at rates of :
  • 28 cents (9-11PM)  
  • 13 cents (11PM-7AM) or
