Bay Area (PG&E) NEM 3.0 Solar & Battery Math: E-ELEC Rates & PSPS Backup
Cities Covered: San Francisco, San Jose, Oakland, Fremont, Santa Rosa, Walnut Creek, Palo Alto
After six consecutive CPUC rate hikes, Bay Area homeowners on PG&E pay $0.41/kWh off-peak and up to $0.66/kWh during summer 4–9 PM peak hours—while enduring frequent Public Safety Power Shutoffs (PSPS). Here is how to combine solar with a 14.3kWh–28.6kWh LFP battery to slash payback to 4.5 years.
San Francisco Bay Area Solar & Battery Payback Comparison (2026)
| Configuration | Upfront Net Cost | Year-1 Savings | Payback | 2026 Verdict |
|---|---|---|---|---|
| Solar Only (No Battery) | $24,500 | $1,480 / yr | 16.5 Years | 🔴 Unviable — Midday exports credited at ~4¢/kWh |
| Turnkey Installer Solar + Battery | $39,800 | $4,050 / yr | 9.8 Years | 🟡 High contractor & loan dealer-fee bloat |
| Solar + Direct Battery (Save $10k+ w/ EG4 / EcoFlow) | $15,800 (Hardware + Local Elec.) | $3,510 / yr | ⚡ 4.5 Years | 🟢 Optimal ROI + Full Wildfire PSPS Outage Defense |
⚡ 2026 TARIFFS📊 Full 2026 Pacific Gas & Electric (PG&E) Rate Schedule, TOU Windows & Fixed ChargesE-ELEC (NEM 3.0 Solar Billing Plan) · Peak: $0.58 – $0.66 / kWh · Off-Peak: $0.39 – $0.43 / kWh (Midnight–3pm)
PG&E forces all new NEM 3.0 solar customers onto the E-ELEC tariff. Because even PG&E's 'off-peak' rate is ~$0.40/kWh and summer peak hits $0.64/kWh, self-consuming 100% of your solar generation via an indoor/outdoor UL9540 battery yields massive year-round savings—plus September evening grid exports earn $2.00+/kWh.
| Primary Solar Rate Schedule | E-ELEC (NEM 3.0 Solar Billing Plan) |
|---|---|
| 2026 On-Peak Tariff Rate | $0.58 – $0.66 / kWh |
| Part-Peak / Shoulder Rate | $0.46 – $0.51 / kWh (3–4pm & 9pm–12am) |
| Off-Peak / Super Off-Peak Rate | $0.39 – $0.43 / kWh (Midnight–3pm) |
| Fixed Monthly Customer Charge | $15.00 / mo (E-ELEC Base Services Charge) |
| 2026 Grid Export Credit Rule | CPUC ACC Schedule: ~$0.03–$0.05/kWh midday; $2.00–$3.10/kWh Sept 6–8pm export bonus |

FAQ❓ San Francisco Bay Area (Pacific Gas & Electric (PG&E)) Solar & Battery FAQsAnswers on local TOU windows, export credits, and battery payback
How do PG&E's September ACC export credits work in the Bay Area?
Under PG&E's Solar Billing Plan, the Avoided Cost Calculator (ACC) pays over $2.00 to $3.00 per kWh exported between 6:00 PM and 8:00 PM in September. Programming an EG4 18kPV or EcoFlow Delta Pro Ultra to dump 10kWh per evening during September generates $600–$900 in bill credits in a single month.
Do Bay Area building departments require UL9540 certification for home batteries?
Yes. Cities across Santa Clara, Alameda, Contra Costa, San Mateo, and Marin counties strictly enforce California Residential Code R328 and UL9540 listing. Both the EG4 18kPV + PowerPro WallMount and EcoFlow Delta Pro Ultra hold full UL9540 certifications.
