FAQs About Solar and Electrical Services in Tempe, AZ
Most Tempe addresses are served by Salt River Project (SRP), though Arizona Public Service (APS) provides electricity to a portion of the city as well. Your utility provider depends on your specific address. During your consultation, we confirm which utility serves your home and design your solar system around that utility’s rate structure and interconnection requirements.
Yes. Homes near Arizona State University and the surrounding corporate corridor tend to run cooling systems and electronics heavily throughout the day. A properly sized solar system can offset a significant portion of that daily electricity use, and pairing it with battery storage extends those savings into the evening hours.
It depends on your home’s existing electrical capacity and the type of charger you want installed. Many homes can support a Level 2 charger without any upgrades, while others need a panel or subpanel upgrade to safely handle the additional load. We assess this during your consultation.
Battery storage is worth considering for most Tempe homeowners, particularly for those on SRP’s demand-based rate plans, where reducing peak-hour grid usage can meaningfully lower monthly bills. Battery storage also keeps essential appliances running during outages.
Most residential solar installations in Tempe take one to three days once permits are approved. The full process, including design, permitting, and utility approval, typically takes a few weeks from your initial consultation to system activation.
