Navigating APS's Time-of-Use Hours Shift for Solar Customers

APS's recent update to its time-of-use rate plans, which now run from 4-7 pm on weekdays, presents new considerations for solar customers in Arizona.

  1. Understanding the New Peak Hours: The 4-7 pm shift reduces the peak window. This is beneficial as it falls within most existing solar system configurations, initially set for 3-8 pm.

  2. System Updates for Efficiency: While current settings should still be effective, solar customers may need to update their battery and demand manager settings once APS confirms the changeover for their specific meter.

  3. Timeline for Changes: APS's rollout of these updates is expected to span from May through late July or early August 2024. Customers will be notified about the change to their meter, indicating the appropriate time to update their systems.

  4. Manufacturer-Specific System Updates: Depending on your solar system's make, updates may be automatic (as with Inergy and Generac) or manual (Tesla Powerwall, Brayden). Waiting for APS's notification before adjusting your settings to ensure optimal system performance is crucial.

  5. Support and Guidance: Sun Valley Solar Solutions recommends patience during this transition. Premature updates can lead to inefficient energy use and higher bills. Once notified by APS, follow the specific instructions for your system to adjust to the new peak hours.
