Is solar worth it in California in 2026? The honest answer depends less on the state as a whole and more on which utility bills you every month. PG&E, SCE, and SDG&E charge meaningfully different rates, and that gap changes the numbers more than most homeowners expect. This piece breaks down NEM 3.0 and the sunset federal credit. It compares utility-by-utility pricing and maps out payback timelines. And it covers which incentives are still standing for property owners weighing a purchase this year.
Regulatory Shifting Points: The Impact of NEM 3.0 and Sunsetted Federal Tax Credits
Two Changes That Reshaped the Math
Two big changes reshaped the numbers behind California solar in the last few years. Both push the value of a system toward using your own power, not selling it back. NEM 3.0, California's current net billing rules, cut what utilities pay for exported solar power by an estimated 75%. Export credits now track the grid's actual avoided cost rather than the retail rate, according to the California Public Utilities Commission. That's exactly why self-consumption now matters more than exporting.
The 30% federal residential solar tax credit expired for good on December 31, 2025. A system completed in 2026 gets no credit at all under IRS guidance, now that the credit's final deadline has come and gone.
Third-party-owned systems, leases and PPAs, can still access a similar federal credit indirectly through the provider's own commercial tax credit. That's exactly why leasing has become a more common route for homeowners chasing that benefit without owning the system outright.
What This Means for the Payback Case
Together, these two changes mean the financial case for solar in California now rests almost entirely on how much a system offsets your own bill. What it earns back from the grid barely factors in anymore. Since self-consumption is now the whole game, the number that matters most is what your specific utility actually charges for the power you're offsetting.
Comparative California Electric Tariffs: PG&E vs. SCE vs. SDG&E
Rates vary enough between the state's three major utilities that a statewide average hides the real picture entirely.
Utility | Average Residential Rate | Peak Time-of-Use Rate |
|---|---|---|
SDG&E | About 46¢/kWh | 60¢ or more/kWh (4 to 9 PM) |
PG&E | About 40.6¢/kWh | Up to 52 to 54¢/kWh (4 to 9 PM) |
SCE | About 34.5¢/kWh | Up to 74¢/kWh (5 to 8 PM) |
SDG&E customers pay the highest average electric rates in the continental United States. Base energy costs so much there that every kilowatt-hour a solar-plus-battery system offsets is worth more. San Diego homeowners see that value faster than almost anywhere else in the state.
PG&E's default time-of-use plans push peak evening rates past 50 cents per kWh. Under NEM 3.0, that rate structure is a big reason pairing a system with home battery storage matters so much now. It's often what makes solar actually pay off.
SCE runs the lowest average residential rates of the three, even after Climate Credit adjustments. Lower underlying prices naturally stretch out the payback period for SCE customers. That's true even compared to PG&E or SDG&E with an identical solar array on the roof.
Rate differences this large don't just show up on the monthly bill. They change how long a system actually takes to pay for itself.

Calculating Payback Variations Across Utility Territories
The Baseline Payback Range
Industry estimates commonly put California solar payback around 7 to 10 years for a system bought outright: a range that comes from the the same ROI calculation applied broadly, not any one utility's actual rate. Where you land in that range depends on your starting rate: every kWh of self-consumed solar replaces more expensive grid electricity, so the same system pays back faster for an SDG&E customer than an SCE customer, all else being equal. Without federal credit lowering upfront costs anymore, that gap between a high-rate utility and a low-rate one matters more than it used to: There's no credit left to soften a slower payback on the cheaper side.
Why a Longer Payback Still Works
A 20 to 25 year system lifespan against even a stretched 9 to 10 year payback still leaves well over a decade of largely offset electricity once the system pays for itself. These payback numbers assume no additional help, and a few state and utility-level programs are still worth checking before ruling anything out.
Active Solar and Storage Incentives Across California
The federal credit is gone, but it's not the only incentive left standing. A few state-level programs still help offset the upfront cost. California's Self-Generation Incentive Program still offers battery rebates. Its current funding is concentrated in a low-income equity budget, though, rather than being broadly available to every homeowner.
The state's active solar property tax exclusion is still in effect, meaning a new solar installation won't trigger a property tax reassessment. Per the California State Board of Equalization, the sunset date for the exclusion of new installations is January 1, 2027.
PACE financing remains an option too, spreading the cost over 10 to 20 years with no money down. That's useful for homeowners who don't want to race the property tax deadline.
Some individual utilities and cities offer smaller local rebates on top of these. It's worth checking with a specific provider rather than assuming statewide numbers apply everywhere.
Final Verdict: Is California Solar Worth the Investment in 2026?
For most property owners, solar still makes financial sense in 2026. Precise value depends heavily on your utility, though, with SDG&E territory delivering a noticeably stronger return than SCE territory at today's rates.
Adding home battery storage has gone from a nice-to-have to close to a requirement. NEM 3.0's export rates no longer pay much for power sent to the grid. The same panel-and-inverter setup that once counted on selling excess power back now needs somewhere to actually put that extra energy.
Anyone hoping to use the state property tax exclusion is working against a real deadline. Systems completed after January 1, 2027 won't qualify under the current statute.
Conclusion
Solar still pays off for most California homeowners in 2026, but the real payback number depends heavily on which utility is on your bill. SDG&E and PG&E customers see a stronger case than SCE customers at today's rates. Run the numbers against your own utility's current rate, not a statewide average, and budget for a battery from the start. NEM 3.0 has made exporting power worth far less than using it, and EcoFlow's TITAN lineup is built to help you use it.
FAQs
Is solar power worth it in California in 2026?
For most homeowners, yes, though the exact payback depends on your utility's rates. SDG&E's high rates make solar pay off faster, while SCE's lower rates stretch the timeline. Battery storage matters more than it used to, since NEM 3.0 pays much less for exported power.
Is solar still worth it in California after NEM 3.0?
Yes, but the calculation has shifted. NEM 3.0 cut export compensation by roughly 75%, so the value now comes mostly from using your own power instead of selling it back. A system paired with battery storage, like EcoFlow's TITAN series, captures more of that value than a panels-only setup.
Is it worth getting solar in California without the federal tax credit?
It can still be, especially in high-rate territories like SDG&E and PG&E. Without the 30% credit, upfront costs are higher and payback stretches out, typically to somewhere around 7 to 10 years depending on your utility and system size.
Does it matter which utility I'm on for solar to be worth it?
Yes, significantly. SDG&E's rates run nearly 46 cents per kWh on average, SCE's sit closer to 34.5 cents. That roughly 12-cent gap changes payback timelines by a meaningful margin, even for two otherwise identical systems.
Do I need a battery for solar to be worth it under NEM 3.0?
Not strictly required, but it's close to essential for maximizing value. Since NEM 3.0 pays so little for exported power, storing your own generation for evening use, when rates are highest, is usually what makes the numbers work best.
