PG&E NEM 3.0 Solar Payback Calculator & Rules (2026 Guide)
PG&E NEM 3.0 Solar Payback Calculator & Rules (2026 Guide)
If you are a Pacific Gas & Electric (PG&E) customer in Northern or Central California, electricity prices have surged to historic highs. At the same time, California’s NEM 3.0 (Net Billing Tariff) fundamentally altered how solar generation is credited.
If you send daytime solar power back to PG&E, you receive pennies on the dollar. However, if you store that energy in a home battery, you offset peak utility rates exceeding $0.58 per kWh.
PG&E Peak Tariff Rates vs. Export Credits
Under NEM 3.0, the value of unbuffered daytime solar exports dropped by approximately 75%.
- Peak Evening Rate (4 PM – 9 PM): ~$0.56 – $0.62 per kWh
- Average Grid Export Credit: ~$0.05 – $0.08 per kWh
This gap creates a massive financial incentive to store every single kilowatt-hour generated by your solar roof.
Payback Comparison for PG&E Customers
| System Setup | Average Net Investment | Est. Annual Savings | Real Payback Period |
|---|---|---|---|
| Solar Only (8 kW) | $13,500 | $1,500 / yr | 9.0 Years |
| Solar + Battery (8 kW + 13.5 kWh) | $21,000 | $4,200 / yr | 5.0 Years |
Action Plan for PG&E Homeowners
- Size for Self-Consumption: Do not install an oversized panel system meant for grid export.
- Claim 30% Federal ITC: Deduct 30% of total equipment and installation costs on tax filings.
- Audit Local ZIP Code Incentives: Certain PG&E zones qualify for additional SGIP equity rebates.
