Your PG&E, SCE, or SDG&E bill probably climbed again this year, while NEM 3.0 cut what solar panels earn for sending power back to the grid. That leaves a fair question: is solar still worth it in California in 2026?
The short answer: yes, for most homeowners with a meaningful electric bill, but only if the system is designed for today’s rules. That means sizing it to your real usage and, in most cases, adding a battery.
- Best fit: monthly bill of $150 or more, a sunny roof with years of life left, and plans to stay in the home 7 or more years.
- Typical payback: roughly 7 to 12 years with a battery, and 9 to 13 years for solar only, depending on your utility and system price.
- What changed: exports earn far less under NEM 3.0, and the 30 percent federal tax credit ended for purchased systems installed after December 31, 2025.
- What did not change: California electricity is still among the most expensive in the country, so every kilowatt-hour you make and use yourself is worth full retail value.
Is Solar Worth It in California? Quick Verdict by Situation
| Your situation | Worth it in 2026? | Why |
|---|---|---|
| Bill above $250 per month, solar plus battery | Usually yes | Enough bill to offset, and a battery covers the expensive evening peak |
| Bill of $150 to $250 per month | Often yes, run the numbers | Payback depends on system price, financing, and roof |
| Solar only, no battery | Marginal for many homes | Exports earn low credits while evening power is bought back at peak prices |
| Bill under $150 per month | Usually not yet | Too little bill to offset the system cost |
| Roof needs replacing soon | Fix the roof first | Removing and reinstalling panels later adds cost |
| Moving within 3 to 5 years | Usually no | Payback takes longer than you will own the home |
These are rules of thumb, not guarantees. Your roof, usage pattern, rate plan, and financing set the real number.
What Changed for California Solar in 2026
Two policy changes reshaped the math. Neither ended the case for solar, but both changed how a good system is built.
| Topic | Before | Now |
|---|---|---|
| Export credit for excess solar | Close to full retail value under NEM 2.0 | Avoided cost rates under NEM 3.0 (Net Billing Tariff), roughly 75 percent lower in many cases |
| Where the value comes from | Selling extra power to the grid | Using your own power directly or from a battery |
| Federal tax credit for purchased systems | 30 percent credit | Ended for systems installed after December 31, 2025 |
| Best system design | Panels sized to produce as much as possible | Panels sized to your usage, usually with a battery |
NEM 3.0 applies to new customers of PG&E, SCE, and SDG&E. Municipal utilities such as LADWP and SMUD are not covered by it, so their solar economics work differently. If you are an LADWP customer, see our breakdown of LADWP solar and battery costs.
As of 2026, NEM 3.0 remains in effect. Plan around the current rules instead of waiting for a reversal. For a deeper look at how net billing changes a quote, read how NEM 3.0 changes your solar savings estimate. You can also read the CPUC’s overview of net billing.
California Electric Rates by Utility in 2026
The real case for solar has always been the utility bill. According to the CPUC Public Advocates Office, March 2026 residential average rates were:
| Utility | Average residential rate | Notes |
|---|---|---|
| Southern California Edison (SCE) | About 34.5 cents per kWh | Time-of-use plans price evening power highest |
| Pacific Gas and Electric (PG&E) | About 33.7 cents per kWh | Other sources quote higher bundled rates, so check your own bill |
| San Diego Gas and Electric (SDG&E) | About 45.7 cents per kWh | Highest of the big three, which shortens solar payback |
Rates at the three big utilities have risen roughly 93 to 117 percent since 2014, well ahead of inflation. Higher rates raise the value of every kilowatt-hour your system keeps you from buying.
Why a Battery Now Decides the Outcome
Under NEM 3.0, solar that pushes cheap midday power to the grid and buys expensive evening power back loses value. A battery fixes that gap.
- It stores midday solar that would otherwise earn a low export credit.
- It releases power during the 4 PM to 9 PM peak, when time-of-use rates are highest.
- It raises self-consumption, so more of your production offsets full retail prices.
- It provides backup power. Solar-only systems shut down during a grid outage or Public Safety Power Shutoff. A backup-enabled battery keeps your essentials running.
Most new California installations now include storage for this reason. For the cost side of the decision, see how much a solar battery costs. To understand why the evening window matters so much, read our guide to time-of-use solar savings.
How Long Does Solar Take to Pay Off in California in 2026?
With no federal credit on a purchase, payback is simply system cost divided by the bill you stop paying. Typical ranges reported by California installers in 2026 look like this:
| System type | Typical payback | Main driver |
|---|---|---|
| Solar plus battery | About 7 to 12 years | Battery captures the evening peak |
| Solar only | About 9 to 13 years | Depends on how much power you use during the day |
| Faster end of each range | SDG&E territory | Highest retail rates of the big three |
| Slower end of each range | SCE and PG&E territory | Lower average rates |
Panels are built to last 25 years or more, so even a 10-year payback leaves well over a decade of low-cost power. For a full breakdown, see our solar panel payback period guide and try the California solar savings calculator.
Is Solar Worth It Without the Federal Tax Credit?
Usually yes, because the tax credit was never the main reason solar works in California. The utility bill is. Here is what is still available:
- Purchased systems (cash or loan): no federal credit for systems installed after December 31, 2025. The IRS Residential Clean Energy Credit page confirms the cutoff.
- Leases, PPAs, and prepaid agreements: the company that owns the system may still claim a commercial credit, and some providers pass part of that value through as lower pricing. These programs have deadlines and contract terms, so get the details in writing. See our comparison of solar lease vs loan vs cash in California.
- State and local programs: battery rebates such as SGIP have narrowed, and remaining help is mostly aimed at income-qualified or high fire risk households. Confirm current availability before it goes into your math. Our 2026 solar incentives guide tracks what is open.
- If your system was completed in 2025: you may still be able to claim the credit on your 2025 tax return. Ask a tax professional.
When Solar Is Not Worth It in California
Solar is not the right move for every home. Be cautious if any of these apply:
- Your bill is small. Under about $150 per month, there is often too little to offset.
- Your roof is shaded for much of the afternoon.
- Your roof is near the end of its life. Check our guide on whether your roof is too old for solar panels.
- You plan to move soon, before the system pays for itself.
- Your loan has heavy dealer fees that eat the savings.
- The design is solar-only, and most of your usage happens after sunset.
None of these mean never. They mean fix the problem first, or rerun the numbers when your situation changes.
Quick Checklist: Is Solar Worth It for Your Home?
Solar is likely worth it if most of these are true:
- Your monthly bill is $150 or more, and ideally above $250.
- You live in PG&E, SCE, or SDG&E territory and can add a battery.
- Your roof gets strong sun and has 15 or more years of life left.
- You plan to stay in the home at least 7 years.
- Your financing is low-cost, or you pay cash.
- You expect more electric use soon, such as an EV or heat pump.
Solar can also support resale value. See whether solar increases home value.
What to Ask Before Choosing a Solar Installer
- How is the system sized relative to my actual usage and evening peak?
- Does the estimate value exports at current NEM 3.0 rates, not old retail credits?
- What is the price with and without a battery?
- Does the warranty cover performance and workmanship, not only equipment?
- Is the pricing truly factory direct, or does it include a distributor markup?
- What is the installation timeline after approval?
The Bottom Line
Solar is still worth it in California in 2026 for homeowners with a meaningful bill, a good roof, and a plan to stay put. NEM 3.0 and the end of the federal credit moved the value from selling power to using it, which rewards right-sized systems paired with a battery.

Frequently Asked Questions About Solar in California
Is solar still worth it in California after NEM 3.0?
Yes, for most homeowners with a meaningful electric bill. NEM 3.0 lowered export credits, so the savings now come from using your own solar power directly or through a battery. A properly sized solar plus battery system still typically costs less over its life than staying with the utility.
Is solar worth it in California without a battery?
Sometimes, but it is the marginal case. Solar only works best when you use a large share of your power during the day. If most of your usage happens after sunset, you will export at low credits and buy back at peak prices, which lengthens payback.
Is solar worth it in California without the federal tax credit?
Usually yes. The credit ended for purchased systems installed after December 31, 2025, but high utility rates drive most of the savings. Leases, PPAs, and prepaid agreements may still pass through commercial credit value, so compare structures before you decide.
Will NEM 3.0 be overturned in California?
As of 2026, NEM 3.0 remains in effect. Homeowners should plan around the current rules rather than wait for a change. Existing customers keep the terms in place when their system received Permission to Operate.
How much does NEM 3.0 pay for solar exports?
There is no single payout. Export credits vary by utility, season, and hour, and they are usually far below the retail rate you pay. Evening hours generally carry the highest export value, which is one more reason batteries help.
What monthly electric bill makes solar worth it in California?
A common rule of thumb is $150 or more per month, with the strongest cases above $250. Below that, there is often too little bill to offset the system cost.
Is solar worth it with LADWP?
LADWP is a municipal utility and is not covered by NEM 3.0, so its economics differ from PG&E, SCE, and SDG&E. See our guide to LADWP solar and battery costs for details.
What happens to my solar system if I sell my house?
Owned solar systems typically transfer with the home, and buyers increasingly view solar plus battery as a plus. For manufacturer warranty questions during a sale, you can speak directly with the QCells team.
