YOUR ELECTRIC BILL · GUIDE 03
Will You Still Have an Electric Bill After Installing Solar?
Solar changes how much electricity you buy from the grid; it does not normally end your relationship with the utility.

Yes, most grid-connected homes still receive a bill
Your home uses solar electricity while the system is producing. When demand exceeds production—often at night or during cloudy periods—it draws from the grid unless a battery supplies the difference. When production exceeds demand, electricity may be exported for bill credits under the applicable utility tariff.
The utility statement records grid imports, exports, credits, and charges. It is not a complete record of all electricity the home used because energy consumed directly from solar never passes through the utility meter as a purchase.
What can remain on the bill
Common items include electricity purchased from the grid, basic service or minimum charges, non-bypassable charges, taxes, and other tariff-specific items. A battery may shift some grid purchases, but does not necessarily eliminate fixed charges.
Bills differ by PG&E, SCE, SDG&E, and municipal utility. Read the rate name and tariff on your own statement rather than applying a sample bill from another utility.
How energy flows during a typical day
In the morning, production rises and serves the home's live demand first. Around midday, excess may charge a battery or flow to the grid. In the evening, solar output falls while cooking, cooling, and vehicle charging may continue; the home then uses stored energy or buys from the grid.
Under California net billing, the price avoided by using solar onsite can differ from the credit earned by exporting it. That is why a yearly production total alone cannot predict the bill.
How to read a post-solar bill
Find imported kWh, exported kWh, energy charges by time period, export credits, fixed charges, prior credit balance, and annual true-up information. Compare several months because summer production and winter use can be very different.
Also check the inverter or monitoring app for total solar production. Utility exports are not the same as production: production equals direct household use plus battery charging and exports, after relevant losses.
Set a realistic expectation before installation
Ask the proposal to show the remaining utility bill separately from any solar loan, lease, or PPA payment. Confirm the rate plan, export assumptions, fixed charges, seasonal pattern, battery behavior, and planned future loads.
The useful target is not a dramatic 'zero bill' claim. It is a transparent estimate of the combined cost of utility service and the solar agreement.
Frequently asked questions
Why is my first bill still high?
Timing, seasonal use, incomplete billing cycles, rate-plan changes, or a system issue can all matter. Compare meter and monitoring data before drawing a conclusion.
Does a battery remove the utility bill?
Not necessarily. It may reduce grid purchases and shift energy, while fixed or tariff-specific charges can remain.
Are exports the same as solar production?
No. Exports are only the energy left after onsite use and, when present, battery charging.
