Simply login to your SCE (or PGE) account and download your hourly usage data in CSV format.

Q & A:
In California, SCE and PGE offer energy rates specifically for EV owners.

- Is it worth it to switch to Schedule TOU?
- An electric vehicle uses about 1.5 kilowatts per hour when charging at 110 Volts AC. Will I get bumped to the next Tier cost basis? How much will that cost me?
- I don't have an electric car but I want to eliminate my electric bill altogether. How many solar panels will I need to have zero electric bill?
- The car costs too much to charge. Can I reduce or eliminate that cost by installing solar panels?

How to add an electric vehicle to your bill:

Note: if your usage already contains an EV, you can alternatively remove it by entering a negative number.

- Check the box "Add EV kWh (12-6AM)".
- Enter the number of kilowatts your EV uses per hour.
- Click the "Refresh" button.

- The program adds an EV only during Super-Offpeak hours.
- Example 1: 3.52 = Nissan Leaf hourly charging rate at 220 Volts @ 16 Amps.
- Example 2: 1.32 = Ford Fusion Energi hourly charging rate at 110 Volts @ 12 Amps.

How to calculate your electric bill in preparation for adding solar panels:

- Check the box "Add Solar kWh".
- Enter the number of total kilowatts produced per hour by your future solar panels combined (at peak sun). Increase or decrease this number to suit your bill.
- Click the "Refresh" button.

- Example: if your desired kWh number is 6.5 kWh you will need 26 solar panels of 250 watts each. 6.5 kWh = 6500 watts / 250 watts = 26 panels.
