What homeowners should know
- The Solar Billing Plan replaced NEM 2.0 for new applicants after April 14, 2023.
- Residential Solar Billing Plan customers are generally placed on TOU-D-PRIME.
- Energy Export Credit values vary by time and season.
- Older eligible NEM accounts may continue under legacy rules until eligibility ends.
Important: Utility tariffs change. Confirm the current rate schedule, interconnection agreement and export-compensation rules for your exact account before signing a solar proposal.
California electricity and solar context
The state electricity-rate figure is a statewide EIA benchmark, not the utility tariff on your bill. Utility plans can differ because of time-of-use periods, tiers, fixed charges, riders, supply choice and solar-export treatment.

Home Solar Atlas summarizes homeowner-facing rules but treats the utility's current tariff and interconnection documents as the controlling source.
Before you compare installer quotes
- Use 12 months of actual electricity consumption rather than only your average bill.
- Ask the installer which utility rate plan and export-compensation schedule the savings model assumes.
- Separate self-consumed solar value from exported-energy value if the utility uses net billing.
- For time-of-use tariffs, compare when the home imports energy with when solar exports occur.
- Model battery economics separately instead of assuming every exported solar kWh has retail value.
