Most homeowners treat solar as a yes-or-no decision, and treat staying on the grid as the safe default. But “keep paying the utility” is a choice with its own moving parts: rates you do not control, no equity at the end, and no protection when the power goes out. This guide compares solar and grid electricity category by category, so you can weigh both paths on the same terms.
Quick answer
- You stay connected to the grid. Nearly all home solar is grid-tied, so going solar does not mean going off the grid.
- Your bill becomes controllable. You generate part of your own power instead of buying all of it at the utility’s rate.
- NEM 3.0 changed the math. Exported power earns a low credit, so using or storing your own power matters most.
- Outages need a battery. Solar panels alone shut down when the grid goes down.
Solar vs Staying on the Grid: Side-by-Side Comparison
| Category | Staying on the grid only | Going solar (grid-tied) |
|---|---|---|
| Connection to utility | Yes | Yes, unchanged |
| Upfront cost | None | Yes, unless you finance or use a PPA |
| Monthly electric bill | Full bill, set by the utility | Much smaller bill, plus any financing payment |
| Exposure to rate increases | Every increase hits your whole bill | Increases hit only the power you still buy |
| Power during an outage | None | None without a battery, backup power with one |
| Equity at the end | None | You own a system that keeps producing |
| Maintenance | None | Light, such as occasional cleaning and monitoring |
| Home value | No effect | Can add resale appeal |
Does Going Solar Mean Going Off the Grid?
You Stay Connected Either Way
For the overwhelming majority of homeowners, no. A standard residential solar system is grid-tied. Your panels supply power during the day, and the grid fills in at night or whenever your production falls short. You keep one foot in each world.
What Does Not Change When You Go Solar
- Your wiring and appliances
- Your ability to draw utility power at any hour
- The fixed monthly charges your utility bills for the connection
The switch is additive: you layer your own generation on top of the connection you already have. If you are curious about fully disconnected setups, our guide to grid-tied, off-grid, and hybrid solar systems explains how each one works and what it costs.
Your Electric Bill: A Fixed Cost vs. a Controllable Cost
What Staying on the Grid Costs Over 25 Years
When you stay on the grid, your bill is set by someone else and tends to move in one direction. The table below shows an example household using 9,000 kWh per year at 32 cents per kWh. Swap in your own usage and rate from your latest bill.
| Yearly rate increase | Bill in year 1 | Bill in year 10 | Bill in year 25 | Total over 25 years |
|---|---|---|---|---|
| 0 percent (flat rates) | $2,880 | $2,880 | $2,880 | About $72,000 |
| 3 percent per year | $2,880 | About $3,760 | About $5,850 | About $105,000 |
| 4 percent per year | $2,880 | About $4,100 | About $7,380 | About $119,900 |
This is an illustrative model, not a prediction or a quote. It shows how much money “doing nothing” can add up to. Compare it with an actual system price on our solar cost misconceptions page, which explains why staying on the grid is not as free as it looks.
What Solar Can and Cannot Remove From Your Bill
| Bill component | Effect of solar |
|---|---|
| Energy charges (per kWh) | Reduced a lot, in proportion to what you generate and use |
| Peak time-of-use charges | Reduced further when a battery covers your evening use |
| Fixed monthly charges | Remain, even in months when your usage is covered |
| Grid power at night | Still billed, unless a battery supplies it |
| Export credits | Small credit for surplus power under NEM 3.0 |
The realistic goal is a much smaller and more predictable bill, not a bill of zero. To see how much a system could produce on your roof, use our guide to calculating solar panel output in California.
NEM 3.0: How Solar Changes Your Utility Relationship
Export Credits Are Worth Less Than They Used to Be
Going solar turns you from a pure customer into one who also sends power back. Under NEM 3.0, the credit for that exported power is far lower than under older rules. Sending surplus to the utility is no longer the win it once was, so the design of the system matters more than the number of panels. For the full rulebook, read net metering and NEM 3.0 explained.
Which Utilities NEM 3.0 Applies To
- Large investor-owned utilities: PG&E, SCE, and SDG&E customers who applied after April 2023 fall under NEM 3.0.
- Municipal utilities: LADWP, Pasadena Water and Power, and others set their own rules, so do not assume the same credits apply.
Ask for your utility’s current terms before you compare any quote.
Batteries Change the Equation
Because exports earn little, storing your daytime production and using it in the evening is where much of the value sits. A battery lets you keep more of what you make instead of selling it cheaply and buying it back at peak rates. Storage can also open the door to state and local solar programs that reward it. Staying on the grid keeps you fully exposed to those peak rates with no way to shift around them.
Power Outages: Grid Only vs Solar vs Solar With a Battery
| Setup | During a blackout |
|---|---|
| Grid only | No power until the utility restores service |
| Solar, no battery | No power. The system shuts down for safety, even in full sun |
| Solar with a battery | Home runs on stored solar power, and the system recharges the next day if the sun is out |
Solar Alone Does Not Power an Outage
This surprises many homeowners. A grid-tied system without a battery turns off during a blackout so that utility crews working on downed lines are not put at risk. Panels by themselves do not change your outage experience much.
Battery Backup Is the Real Resilience Upgrade
Add a battery and the picture flips. Your home can run on stored solar while grid-dependent neighbors sit in the dark. How long that lasts depends on battery size and which circuits you power. If you are deciding whether storage is worth it, read: Do you need a battery with solar?
Costs and Ownership: Renting Power vs Owning It
Why the Comparison Is Not Solar Cost vs Zero
Staying on the grid is renting power with nothing to show for it at the end. Going solar is buying an asset that produces value for decades. The upfront cost is real, and what a solar system costs in California depends on size, roof, and storage. But the fair comparison is solar cost versus a lifetime of utility bills.
How Homeowners Pay for the Switch
Very few buyers pay cash. Most use one of several solar financing options, designed so the monthly payment sits near or below the utility bill it replaces. When that works out, you are redirecting money you already spend toward something you own.
The Return Over Time
Solar’s value comes from avoided bills, so judge it in years, not months. Look at the return you can realistically expect instead of best-case marketing numbers.
Everyday Changes: Habits, Monitoring and Home Value
- You pay attention to energy. Solar owners often shift laundry, EV charging, and pool pumps to daytime hours when production is highest.
- You get live data. Monitoring apps show production and consumption in real time, which grid-only customers never see.
- Resale appeal. Solar can help when you sell. See whether solar increases home value.
Who Should Go Solar and Who Might Stay on the Grid
| Situation | Usually points toward |
|---|---|
| Sunny, unshaded roof and a high summer bill | Solar |
| Evening-heavy usage, EV or electric heating | Solar with a battery |
| Frequent outages or wildfire shutoffs where you live | Solar with a battery |
| Heavily shaded or north-facing roof | Staying on the grid, until a roof check says otherwise |
| Very low electric bill | Staying on the grid, or checking the numbers first |
| Renting your home | Staying on the grid, or exploring renter options |
Check Your Own Situation First
- Test whether your electric bill is high enough for solar.
- See whether your home is a good fit for solar.

Frequently Asked Questions About Solar vs Grid Electricity
Does going solar mean going off the grid?
No. Almost all residential solar is grid-tied, meaning your home stays connected to the utility. Your panels supply power during the day, and the grid fills in the rest. Going fully off-grid is a separate, much larger project.
Will solar eliminate my electric bill?
Usually not completely. Solar can shrink the energy portion of your bill dramatically, but fixed monthly charges and any power you draw from the grid still show up on your statement.
Do solar panels work during a power outage?
Not by themselves. A grid-tied system without a battery shuts down during an outage for safety, even in full sun. A battery lets your home run on stored solar power.
Is solar cheaper than grid electricity in California?
For many homes with sunny roofs and high bills, yes, over the life of the system, because solar replaces a utility rate that keeps rising with power you generate yourself. The answer depends on your usage, roof, utility, financing, and whether you add a battery, so compare it using your own bill.
Is staying on the grid actually cheaper than going solar?
Staying on the grid avoids an upfront cost, but you keep paying whatever rate the utility sets. Over 25 years, the total spent on utility bills can be large, so compare the full timeline rather than just today’s bill.
How does NEM 3.0 change the value of going solar in California?
NEM 3.0 sharply lowered the credit for exporting surplus solar power to the grid. That makes using your own power directly, or storing it in a battery for the evening, more valuable than exporting it. NEM 3.0 applies to customers of the large investor-owned utilities, while municipal utilities such as LADWP have their own rules.
How do I know if my home is a good candidate for solar?
The main factors are sun exposure, roof condition and direction, how much electricity you use, and which utility serves you. A sunny roof with a high bill is a strong candidate, while heavy shade or very low usage weakens the case.
