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

Key Takeaways

• SCE export credits under the new NBT26 vintage average just $0.05–$0.08 per kWh — roughly 75% less than NEM 2.0 retail rates
• The ACC Plus adder has fallen to approximately 2.05 cents per kWh and continues declining 20% annually
• Solar-only payback periods have stretched to 12–15 years; solar-plus-storage brings that down to 8–10 years
• SCE's Virtual Power Plant program now pays $2.00 per kWh during peak grid events — making battery discharge your most valuable revenue stream
• 79% of new SCE solar installations now include battery storage, up sharply from just a few years ago
• The strategic question in 2026 is no longer "should I go solar?" — it's "how do I keep as many kilowatt-hours as possible behind the meter?"

If you went solar in 2019 or 2020 under NEM 2.0, you were getting close to retail value — sometimes $0.25 or more per kilowatt-hour — for every electron you pushed onto the Southern California Edison grid. It felt like running a small power plant out of your garage.

That era is over.

In 2026, SCE residential solar customers exporting power to the grid earn somewhere between $0.05 and $0.08 per kWh, according to data from the California Public Utilities Commission and ROI Solar. That is not a rounding error. That is a fundamental restructuring of the California solar economics model, and if you are shopping for solar right now without understanding it, you risk making a very expensive mistake.

This guide breaks down exactly what SCE solar customers will earn from exports in 2026, why those numbers look the way they do, and — more importantly — what strategies actually make solar financially rational in this new environment.

How SCE Export Credits Are Calculated in 2026

Southern California Edison's new interconnection vintage, officially designated NBT26, locks in export credit rates for a 9-year fixed period for all residential customers who interconnect in 2026. Understanding where those rates come from requires a brief look at the underlying mechanics.

SCE export credits are no longer based on retail electricity rates. Instead, they are calculated using California's Avoided Cost Calculator (ACC) — a CPUC-maintained model that estimates the value of solar exports based on what the grid would otherwise have to pay to generate or procure that electricity at any given moment.

The key components of your export credit include:

• Base avoided cost: The wholesale market value of electricity at the time of export — typically very low during midday hours when solar production peaks
• ACC Plus adder: A supplemental credit that partially compensates rooftop solar for its grid benefits — currently set at approximately 2.05 cents per kWh for 2026 interconnections
• Time-of-use adjustments: Credits vary significantly by hour; midday exports (10 AM–3 PM) earn the least, while evening exports are marginally more valuable

The ACC Plus adder is particularly worth watching. It began at a higher baseline in 2023 and is subject to a 20% annual decline per CPUC schedule. By the time a 2026 customer reaches the end of their 9-year NBT26 lock-in window, that adder will have largely evaporated. The CPUC's 2026 ACC update confirmed this trajectory is being accelerated by the rapid buildout of California's utility-scale battery storage infrastructure, which is now approaching 15,000 MW of capacity statewide — reducing the marginal value of additional midday solar exports onto an increasingly saturated grid.

The bottom line on raw export earnings: exporting power to SCE in 2026 is not a revenue strategy. It is a residual. Every kilowatt-hour you send to the grid is a missed opportunity.

The Death of Solar-Only Economics Under SCE

The numbers are unambiguous on this point, and the industry has already responded. Battery attachment rates for new SCE residential solar installations hit 79% in late 2025, according to EnergySage's 2025 Annual Market Report. Installers across Southern California have largely stopped quoting solar-only systems because the return on investment simply does not compete.

Here is why the math breaks down for solar-only customers:

• A solar-only system generates power during daylight hours, much of which cannot be consumed in real time by a typical household
• Excess generation is exported to SCE at $0.05–$0.08 per kWh
• That same household buys back power in the 4 PM–9 PM peak window at SCE's TOU-D rates, which can exceed $0.45 per kWh
• The arbitrage gap — between what you export and what you import — undermines the financial case rapidly

The result: solar-only payback periods for SCE customers in 2026 now average 12–15 years, according to modeling from Infinity Solar and SolarWithWatts. For a technology with a 25–30 year panel lifespan, that is technically viable — but barely, and with significant financial risk embedded in long-horizon utility rate assumptions.

Solar-plus-storage, by contrast, compresses payback to 8–10 years by doing one critical thing: keeping your solar energy on your side of the meter.

"In the SCE territory, the battery is no longer a luxury; it is the brain of the financial model. If you aren't discharging into that 4 PM to 9 PM window, you're essentially donating your energy to the utility for pennies." — Marcus Thorne, VP of Grid Strategy, SunLogic Energy

Where the Real Money Is: VPP Participation

If low export credits represent the challenge, Southern California Edison's expanding Virtual Power Plant (VPP) program under the Emergency Load Reduction Program (ELRP) represents one of the most compelling financial offsets available to 2026 solar customers.

Here is how it works: SCE aggregates residential batteries into a coordinated virtual grid resource. During high-demand events — typically heat waves driving extreme afternoon and evening load — the utility remotely dispatches enrolled batteries to discharge into the home (offsetting grid imports) or, in some configurations, back to the grid. In exchange, participating homeowners earn a premium of $2.00 per kWh discharged during qualifying events.

The program economics are real and significant:

• Average annual VPP earnings for participating SCE customers: $350–$575 per summer season
• Events typically occur 10–20 times per year, concentrated between June and October
• Participation is largely automated through smart inverter integration — homeowners opt in and the system manages the rest

California's milestone of 2 million solar roofs crossed in Q1 2026, and a meaningful portion of that installed base is now VPP-enrolled. Increasingly, solar financing companies are bundling VPP participation agreements into 20-year loan and lease structures as a way to quantify and promise a revenue stream that partially offsets the diminished base export credits.

For any homeowner evaluating solar in SCE territory today, the question should not just be "what will I earn from exports?" but also: "Am I sized and equipped to participate in VPP events?"

Smart Strategies That Are Actually Working in 2026

The homeowners and installers navigating SCE's new credit structure successfully are not fighting the math — they are redesigning their systems around it. Several strategies have moved from experimental to standard practice:

Self-Consumption Optimization

AI-driven energy management systems have become a baseline expectation on new solar-plus-storage installations. These platforms automatically shift flexible loads — EV charging, dishwashers, HVAC pre-cooling — into the midday solar production window, maximizing the kilowatt-hours consumed directly from the panels before anything touches the battery or the grid.

"By 2026, the concept of 'selling' power to the grid is dead. We have entered the era of the 'behind-the-meter' economy where every kilowatt-hour you keep is worth five times more than the one you export." — Dr. Elena Vance, Senior Energy Economist, Pacific Research Institute

Strategic System Oversizing

With California's Electrification TOU rates rewarding flexible consumption and the cost of solar panels continuing to decline, many installers are now recommending systems sized at up to 150% of current household usage. The rationale: homeowners planning to add heat pumps, induction ranges, or additional EVs over the next five years will need that headroom. Sizing for tomorrow's load today locks in the NBT26 vintage at current ACC Plus adder levels before they decline further.

Battery Dispatch Timing

The 4 PM–9 PM SCE peak window is where battery value is maximized. A well-configured system charges from solar midday and discharges during peak hours, avoiding retail import rates that can top $0.45 per kWh. Combined with VPP participation during grid stress events, a properly sized battery system can generate returns that solar-export credits alone never could.

The Nano-Grid Mindset

The most financially resilient SCE solar customers in 2026 are approaching their systems not as grid-connected generators, but as home energy nano-grids — self-contained units that interact with the utility strategically rather than passively exporting everything they produce. This reframing changes every design decision: battery sizing, inverter selection, load management, and VPP enrollment all follow from the goal of maximum behind-the-meter efficiency.

What to Ask Before You Sign Anything

Given how dramatically the financial model has shifted, the due diligence required before committing to a solar installation in SCE territory is more rigorous than it has ever been. Key questions to demand answers to:

• What vintage will my system interconnect under? NBT26 locks in rates for 9 years — confirm this in writing.
• What are my modeled export earnings vs. self-consumption savings? Any credible financial projection must separate these two numbers.
• Is battery storage included, and what is the dispatch strategy? A battery without a programmed peak-discharge strategy is an expensive backup generator.
• Am I eligible for SGIP incentives? California's Self-Generation Incentive Program still offers rebates for battery storage in many SCE zip codes, meaningfully improving system economics.
• What is the installer's NABCEP certification status and track record in SCE territory specifically? NEM 3.0 and NBT26 interconnection paperwork is complex; installer experience with SCE's processes directly affects your timeline and your final credit vintage.

Bottom Line

SCE solar export credits in 2026 are not what they were, and any financial model built on the assumption that you will profitably "sell" power to the grid the way NEM 2.0 customers once did is a model built on fiction. The average $0.05–$0.08 per kWh export rate is a residual — useful as a last resort, not a business plan. The homeowners who are making solar work in this environment are keeping more power behind the meter, discharging batteries into peak windows, participating in VPP programs that pay $2.00 per kWh during grid stress events, and thinking about their rooftop systems as nano-grids rather than mini power plants.

The financial case for solar in SCE territory in 2026 is real — but it requires precise system design, NEM 3.0-aware financial modeling, and an installer who genuinely understands the SCE-specific landscape. Getting that wrong is a 25-year mistake.
