Peoria’s West Valley location gives it the same 300-plus days of annual sun as the rest of the Phoenix metro, with APS as the utility delivering a more straightforward solar economics picture than SRP. APS time-of-use plans have on-peak hours from 4–7 p.m. on weekdays — a window when solar production is tapering but still generating, and when stored energy from batteries becomes particularly valuable. Export compensation of approximately $0.069/kWh is locked in for 10 years from interconnection, giving Peoria homeowners meaningful long-term rate predictability. Summer cooling loads are substantial in Peoria, particularly in larger homes and those with pools, creating high consumption that a properly sized solar system can offset at retail rates.
Arizona Public Service is the primary utility for Peoria residential customers. APS’s solar rate framework is notably more straightforward than SRP’s, though it still rewards thoughtful system design.
APS residential solar customers are placed on time-of-use rate plans. On-peak hours run from 4 p.m. to 7 p.m. on weekdays, year-round. The on-peak rate in summer 2026 runs approximately $0.29/kWh — more than double the off-peak rate. Solar panels produce well through the afternoon but output begins declining by 4 p.m. as the sun angles lower, which means peak-hours production partially but not fully offsets peak-hours consumption. Battery storage, charged from midday solar production, can dispatch during the 4–7 p.m. on-peak window and meaningfully reduce on-peak grid draw.
APS compensates solar exports at approximately $0.069/kWh, locked in for 10 years from interconnection. This is significantly higher than SRP’s $0.0345/kWh export rate, and the 10-year lock provides long-term predictability. APS does not impose monthly demand charges on standard residential solar plans — removing one of the billing complexities SRP customers face.
For Peoria homeowners, the APS framework means solar economics are more predictable and the self-consumption pressure less acute than for SRP customers. A well-sized system can be designed around annual consumption without the same urgency to minimize every kilowatt-hour of export.
Residential solar systems in Peoria typically run 7kW–11kW, sized to match annual household consumption. Battery storage is increasingly common for APS customers who want to maximize the value of their solar production during APS’s 4–7 p.m. on-peak window — the period when grid electricity is most expensive and where a discharged battery delivers maximum bill savings. Peoria’s competitive installer market, serving both the established neighborhoods in south Peoria and newer master-planned communities in the north, means multiple qualified bids are readily accessible. When comparing quotes, confirm that installer experience includes APS interconnection, which has its own application and approval process.
