How does having solar panels impact my participation? Cost, panel sizing, etc.
Initial costs increase slightly, but the ROI may quickly offset this.
The short answer is that your existing solar PV system will not impact your program participation.
The longer answer is that for the California and Connecticut programs, your system will be set up to enable export from both your solar as well as your EV. In this setup, you stay on your existing solar program (known as “Net Energy Metering” or NEM in California or a “Netting Tariff” in Connecticut). Separately, you will get compensated for V2G export under a different program than your solar – Emergency Load Reduction Program (ELRP) or Demand Side Grid Support (DSGS) in California or the V2G demonstration program in Connecticut.
To separately measure the energy from your solar and V2G systems in order to accurately compensate you for the power you provide, the utility installs and charges for a Net Generation Output Meter (NGOM) connection. In California, PG&E currently charges $1,400 for the NGOM, SCE charges $600, and SDG&E charges a minimum of $954. Installing this meter adds a couple hundred to the overall cost.
