What to confirm
- Critical circuits and expected outage runtime
- Existing solar, panel capacity, and utility requirements
- Single-battery versus multi-battery coverage goals
Tempe homeowners on SRP's E-27 plan look at Powerwall to reduce demand charges and store daytime solar for evening use. The planning call models peak window timing, EV charging load, and solar production for the specific home before recommending battery count.
For Tempe, the quote path should confirm service coverage, outage priorities, solar status, EV charging plans, and current installation timing before pricing is treated as final.
PWRHUBUSA currently serves Utah and Arizona. A short call confirms whether the home is inside the active install path and what timing looks like.
Installed cost depends on battery count, backup scope, electrical complexity, and permitting. Use the local call to narrow the project before comparing numbers.
SRP's E-27 Price Plan governs most solar customers in SRP territory. It includes a demand charge based on the highest 30-minute usage window each month. A Powerwall can reduce that peak demand, but dispatch modeling is essential.
Arizona's 25% state solar credit (up to $1,000) and 30% federal ITC both apply. SRP does not currently offer a standalone battery rebate.
The City of Tempe issues building and electrical permits through its community development building safety counter. The SRP interconnection application is separate and can run concurrently.

Tempe outages follow the valley monsoon pattern, and the older distribution areas near the ASU core see somewhat more frequent short interruptions than the newer East Valley suburbs. Summer AC coverage anchors most backup plans.
Tempe's housing stock is the oldest in the East Valley — 1960s–70s ranch homes south of the US-60 and near ASU often carry 100 A panels — so panel upgrades come up more often here than in Gilbert or Chandler. The panel review happens before quoting.
PWRHUBUSA serves homeowners throughout Tempe and the surrounding area, including these neighborhoods and nearby communities. Primary ZIP codes served: 85281, 85282, 85283, 85284.

Multi-BatteryA larger-home planning path for broader backup coverage, heavier loads, and expansion decisions.
EV-ReadyElectrical planning that keeps EV charging, battery reserve, and panel capacity in one design conversation.
Yes — South Tempe, the Kyrene corridor, North Tempe, and the neighborhoods around ASU are all inside the active install area. A short planning call confirms current scheduling.
More often than elsewhere in the East Valley. Many 1960s–70s ranch homes near ASU and south of the US-60 carry 100 A panels; some can host a Powerwall with load management, others warrant an upgrade — especially with EV charging planned. The load calculation decides it.
E-27 bills the highest 30-minute demand window each month, so a battery that shaves evening AC-plus-EV peaks often delivers the largest recurring saving. The planning call models your usage before setting battery count.
