What homeowners should know
- SRP publishes multiple customer-generation and export-oriented solar plans.
- Some plans include demand-based pricing while others use export rates or net-metering features.
- Battery value can depend heavily on the selected plan and peak-demand window.
- Compare the current SRP rate book before relying on a simple cents-per-kWh assumption.
Important: Utility tariffs change. Confirm the current rate schedule, interconnection agreement and export-compensation rules for your exact account before signing a solar proposal.
Arizona 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.

Official SRP solar sources
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.
