Yes, almost always, because a grid connection carries charges that generation does not offset. Whether you still get an electric bill with solar is really a question about which parts of a bill are energy and which parts are access, and only the energy part responds to panels on the roof.
Net zero energy use and a zero dollar bill are different outcomes. Our guide to how long solar takes to pay off covers why that distinction moves the whole payback figure.
A Quick Note
This is general information, not financial or legal advice. Rate structures, fixed charges and export credit rules are set by your state and utility and they change. Read your own bill and confirm current terms with your utility rather than relying on a general description or a sales projection.
Quick Answer
Expect a bill for the fixed portion: a meter or customer charge, and program charges that fund public purpose programs. Generation offsets the energy portion. Staying connected means keeping the connection charges, and going fully bill-free requires disconnecting from the grid entirely, which is a different project.
Key Takeaways
- Fixed and program charges survive any amount of generation.
- The energy portion is what solar actually offsets.
- Some utilities apply a minimum bill regardless of usage.
- Export credit value decides how much energy cost you erase.
- Time of day matters under time-varying rates.
- A zero energy balance is not a zero dollar bill.
- Only disconnecting removes the bill completely.
| Bill component | Does solar offset it? |
|---|---|
| Energy or generation charges | Yes, this is the target |
| Delivery or distribution per kilowatt-hour | Partly, depends on the tariff |
| Fixed meter or customer charge | No |
| Public purpose program charges | Generally no |
| Minimum bill, where it applies | No |
| Taxes and local fees | Follows the taxable portion |
| Demand charges, where they apply | Only if peak draw falls |
A Bill Has Two Different Kinds of Charges
The first kind is volumetric. You pay per kilowatt-hour consumed, and that is the part generation directly reduces.
The second kind is fixed. It pays for the meter, the account, the poles and wires, and programs the regulator has attached to rates.
Solar reduces the first and leaves the second essentially untouched. That is the whole answer in two sentences.
Which means the honest question is what fraction of your bill is which. Our guide to reading a solar monitor covers tracking the volumetric side.
The Charges That Do Not Move
The customer or meter charge
A flat monthly amount for having an account and a meter. It applies whether you import a lot or almost nothing.
Program charges
The California Public Utilities Commission discusses charges that fund public purpose programs such as low-income assistance, energy efficiency programs and wildfire hardening costs. Charges of this kind are commonly structured so generation does not avoid them.
Minimum bills
Some utilities set a floor, so a very low usage month still produces a set amount.
Taxes and local fees
These ride on the charges beneath them, so they shrink with the energy portion and never reach zero while fixed charges remain.
Export Credit Decides How Much Energy Cost You Erase
If exports credit at the retail rate, a kilowatt-hour sent out cancels one brought back. Annual energy cost can approach zero.
The CPUC describes traditional net energy metering as crediting exports at the retail rates, and its newer net billing tariff as crediting at a rate reflecting the value of the generation to the grid, usually lower than the retail rate.
Under the second structure, exporting and reimporting the same quantity leaves you owing money. The gap between the two rates is a real cost.
So two households with identical arrays and different tariffs get different bills. Our guide to Arizona net metering and solar incentives covers a state that moved to an alternative compensation model.
Timing Changes the Total
Under time-varying rates, what you import in the evening can cost considerably more than what you exported at midday earns.
The CPUC has described the net billing tariff as charging customers for grid electricity based on high differential time-of-use rates that vary by time of day.
A household that runs everything after dark therefore pays more than one that shifts load into daylight, with the same panels.
Storage and load shifting are the two levers. Our guide to adding batteries to existing solar covers the first, and our guide to whether charging an EV at home raises your bill covers the load most worth shifting.
Reading Your Own Bill
- Find the fixed charges. Usually labeled customer charge, basic service or similar, and stated as a flat amount.
- Separate energy from delivery. Both can be per kilowatt-hour, and they are often credited differently.
- Look for the program lines. Names vary by state, and these are the ones generation rarely avoids.
- Note whether a minimum applies. A floor changes what a very low month looks like.
- Check the netting period. Monthly and annual netting produce different results from the same array.
- Find your export credit rate. Compare it to what you pay per kilowatt-hour imported.
Our roundup of solar monitoring and production meters covers the equipment that lets you reconcile a bill against actual production.
Why Some People Still See a Large Bill
Undersized arrays are the simplest explanation. A system covering part of your consumption reduces part of the energy cost.
Consumption often rises after an installation, sometimes because a household that generates power uses it more freely.
Shading, soiling and equipment faults reduce output below what was projected, which shows up as a bill rather than as an alarm.
And a sales projection built on retail-rate credit does not hold under a value-based tariff. Our guide to what happens if you oversize your solar array covers the sizing side of this.
Going Bill-Free Means Going Off-Grid
Disconnecting removes the account and therefore the bill. It also removes the grid as a backstop.
That means battery capacity for consecutive cloudy days, generator backup, and accepting that a bad week is your problem to solve.
For most grid-connected households the fixed charge is cheaper than the equipment that would replace the grid.
It is a lifestyle decision more than a financial one. Our guide to running solar panels without a battery covers the opposite end of that spectrum, and our guide to questions to ask a solar installer covers getting a realistic bill projection before you buy.

Frequently Asked Questions
Do you still get an electric bill with solar?
Almost always. A grid connection carries fixed charges, such as a customer or meter charge and program charges, that generation does not offset. Solar reduces the per-kilowatt-hour energy portion, so the bill shrinks rather than disappearing.
What charges does solar not reduce?
Fixed monthly charges for the meter and account, charges funding public purpose programs, and any minimum bill your utility applies. Taxes and fees follow the charges beneath them, so they fall with the energy portion without reaching zero.
Can your bill ever be zero?
Only if your utility has no fixed charge and no minimum bill, which is uncommon. A net zero energy balance is a different thing from a zero dollar bill, and conflating the two is the most common disappointment after an installation.
Why is my bill higher than the sales projection?
Common causes are an undersized array, consumption rising after installation, shading or soiling reducing output, or a projection built on retail-rate export credit when your tariff credits exports at a lower grid-value rate.
Does the time of day matter?
Under time-varying rates, considerably. The CPUC has described the net billing tariff as charging for grid electricity on high differential time-of-use rates that vary by time of day, so evening imports can cost much more than midday exports earned.
What is a minimum bill?
A floor some utilities apply so that a very low usage month still produces a set charge. It exists to recover fixed costs, and it means high generation in a light month does not translate into a proportionally small bill.
Do batteries eliminate the bill?
They reduce the energy portion further by letting you use your own generation after dark instead of buying at retail. They do not touch fixed or program charges, so the bill still arrives.
How do you get rid of the bill entirely?
Disconnect from the grid, which closes the account. That requires enough battery capacity for consecutive cloudy days plus generator backup, and for most households the fixed charge costs less than the equipment replacing the grid.
