SCE Solar Export Credits in 2026: What You'll Actually Earn

Key Takeaways

• SCE export credits under NEM 3.0 pay just $0.05–$0.08 per kWh — roughly 75% less than the retail rate you pay when drawing from the grid
• A small "ACC Plus" residential adder of $0.009/kWh exists in 2026, but it shrinks 20% every year
• The federal 25D tax credit expired December 31, 2025 — new installations no longer qualify
• Self-consumption is now the primary value driver: the less you export, the more money you keep
• Battery storage has shifted from a nice-to-have to a financial necessity under NEM 3.0
• SCE implemented a new rate structure on October 1, 2026, following its 2025 General Rate Case Phase 2 ruling — your old financial models may already be outdated

If you're a Southern California Edison customer who went solar in the last few years expecting a generous monthly check from the utility for your exported power — or if you're considering going solar now — this article is your reality check. The numbers in 2026 tell a story that is fundamentally different from the solar economics of even three years ago, and understanding the gap between what you generate and what you earn is no longer optional. It's the difference between a system that pays for itself and one that quietly underperforms for two decades.

Let's break down exactly what SCE solar customers are actually earning on exported power in 2026, why the math has changed so dramatically, and what the smartest homeowners are doing about it.

The Hard Numbers: What SCE Pays for Your Solar Exports Today

Start with a single, clarifying contrast.

As of July 2026, the average residential electricity rate for SCE customers sits at approximately $0.353 per kWh. That is what you pay when you pull power from the grid during peak hours on a summer afternoon. Now flip the equation: when your solar panels send that same kilowatt-hour back to the grid, SCE compensates you at the Avoided Cost Calculator (ACC) rate — typically between $0.05 and $0.08 per kWh.

That's not a rounding error. That is a value gap of roughly 75–85%.

Under NEM 3.0, formally known as the Net Billing Tariff (NBT), the old net metering math — where a kilowatt-hour out was worth roughly a kilowatt-hour in — is gone. The ACC rate reflects what the utility calculates it would have paid to procure that energy from a wholesale source. It does not reflect the retail value of electricity that your neighbor is buying at $0.353.

There is one small modifier worth knowing: the ACC Plus residential adder, which adds $0.009 per kWh on top of the base ACC rate in 2026. This was designed as a transitional incentive, but it is already eroding — the adder decreases by 20% annually. By 2027 it will be worth $0.0072/kWh. By 2030, it will be negligible. If you're counting on it in your 20-year financial model, you're overcounting.

The October 2026 Rate Change: Why Your Old Projections Are Stale

SCE implemented a rate change on October 1, 2026, following the 2025 General Rate Case (GRC) Phase 2 updates approved by the California Public Utilities Commission. This is not a minor administrative adjustment. GRC Phase 2 proceedings directly govern how SCE structures its Time-of-Use tiers, demand charges, and the baseline allocation that determines how aggressively you're billed.

If you received a solar proposal or ran your own financial model before Q4 2026 — or if your installer used pre-GRC assumptions — your projected payback period and annual savings figures need to be revisited. This is precisely the kind of detail that independent advisory firms track as a core service; solar installers, by contrast, have an inherent incentive to present favorable projections to close a sale.

What Happens to Unused Export Credits?

Under legacy NEM 2.0, unused annual credits could roll over and eventually be paid out — at a reduced rate, but paid nonetheless. That mechanism is effectively gone under NEM 3.0.

New solar customers in 2026 are governed strictly by the Net Billing Tariff, which eliminates the ability to carry over unused annual export credits for cash value. Credits can roll month-to-month within a 12-month billing cycle, but at the end of that cycle, any remaining balance is forfeited — not paid out. You don't get a check. You don't get a credit. It disappears.

The practical implication: if you've sized your solar system the old way — optimized to maximize annual production and export surplus — you may be generating kilowatt-hours that SCE will ultimately compensate you for at near-zero value, or not at all.

The Real ROI Engine in 2026: Self-Consumption

"The era of 'selling back' power for a profit is over," says Dr. Elena Vance, Senior Analyst at the California Renewable Energy Institute. "In 2026, the value of your solar system is defined entirely by how much grid power you successfully avoid purchasing."

This is the core strategic pivot every SCE solar customer needs to internalize. The financial model has inverted:

• Exported kWh → earns $0.05–$0.08
• Self-consumed kWh → avoids paying $0.25–$0.45+ (depending on TOU tier and season)

The spread between those two numbers is where your return on investment actually lives. And the tool that captures that spread is battery storage.

A properly sized and programmed home battery — paired with a smart energy management system — can hold excess solar generation produced during midday low-rate windows and discharge it during SCE's peak TOU periods, typically 4 p.m. to 9 p.m. on weekdays. Instead of exporting that midday solar at $0.06/kWh and then buying back evening power at $0.40+/kWh, you're arbitraging your own clean energy. That is the nano-grid model: not dependence on utility export compensation, but genuine energy independence built on self-sufficiency.

Marcus Thorne, Director of Solar Policy at West Coast Energy Advisors, frames the financial stakes directly: "With the expiration of the 25D tax credit, the ROI for new SCE solar installations now relies heavily on battery integration to capture the spread between low export credits and high retail rates."

The 25D Expiration: A Significant Blow to New Install Economics

The federal Residential Clean Energy Credit — Section 25D — provided a 30% tax credit on the full cost of homeowner-installed solar and battery systems. It expired for new installations on December 31, 2025.

For a $25,000 solar-plus-storage system, that's $7,500 in federal tax credit no longer available to new buyers in 2026. This materially changes payback period calculations and makes accurate, hyperlocal financial modeling more important than ever. Without the 25D subsidy cushioning the upfront cost, getting the system size, orientation, and self-consumption ratio exactly right is no longer just optimization — it's the difference between a 9-year payback and a 14-year payback.

California's SGIP (Self-Generation Incentive Program) battery rebate remains a meaningful offset for eligible customers, particularly those in high fire-threat districts or low-income tiers. If you're in SCE territory and haven't checked your SGIP eligibility, that's the first call to make after reading this article.

Smart Strategies SCE Solar Customers Are Using Right Now

The homeowners navigating 2026's solar economics successfully share a few common approaches:

• Right-sizing for self-consumption, not maximum production: Systems are being designed to cover 85–95% of consumption rather than oversized to generate exportable surplus
• Pairing with battery storage from day one: Given the 25D expiration and the export credit gap, systems installed without storage in 2026 face a longer, harder payback curve
• Leveraging smart energy management systems: Platforms that automate battery charge/discharge timing based on SCE's TOU schedule are becoming standard in well-designed installations
• Waiting for PTO before operating: Running a solar system before receiving official Permission to Operate from SCE carries real risk — zero export credit eligibility and potential billing complications with legacy meters
• Exploring plug-in solar expansion kits: For homeowners with existing systems, modular add-on solutions are gaining traction as a way to offset specific base loads — like EV charging or HVAC — without a full system overhaul
• Monitoring rate escalation as a hedge narrative: With SCE rates projected to increase 2–3% annually through 2028, each incremental rate hike increases the value of every self-consumed kilowatt-hour — making solar-plus-storage an increasingly effective inflation hedge

A Note on Utility-Specific Complexity

SCE is not the only California utility, and even within SCE territory, rate structures vary by program, income qualification, baseline region, and enrollment date. Customers served by Burbank Water and Power (BWP), Pasadena Water and Power, or Glendale Water & Power operate under entirely different tariff structures — some of which remain more favorable to solar exports than SCE's NBT. Applying SCE-specific assumptions to a BWP customer — or vice versa — is a common and costly modeling error.

California solar economics in 2026 are hyperlocal. Satellite irradiance modeling, real shade analysis, and NEM 3.0-aware financial projections that account for your specific utility, rate schedule, and consumption profile aren't a luxury — they're the minimum standard for a responsible solar decision.

Bottom Line

SCE solar export credits in 2026 are not a revenue stream. They are a residual backstop — a minor compensation for energy you couldn't use yourself. The $0.05–$0.08/kWh ACC rate, the eroding ACC Plus adder, the loss of annual credit rollover, and the expiration of the 25D tax credit have collectively rewritten the financial case for rooftop solar in Southern California. The new case is strong — but it's built entirely on self-consumption, battery integration, and precise system design, not on selling power back to the grid.

Homeowners who treat their solar system as a micro-utility — generating, storing, and deploying their own energy strategically — will see the returns the headlines promise. Those who install under outdated assumptions and export their way through summer afternoons will wonder why their bill didn't drop the way they expected.
