About Solar in Tempe
Tempe sits in Maricopa County and is served primarily by Salt River Project (SRP). Tempe is fully SRP territory; SRP’s Customer Generation Price Plan defines export credits for solar. Arizona homeowners benefit from the federal solar Investment Tax Credit (currently 30%), Arizona’s Residential Solar Energy Credit (up to $1,000 off state taxes), and a state sales tax exemption on solar equipment. Permit and interconnection timelines in Tempe typically run 2-4 weeks.
Arizona has the highest solar resource in the United States, averaging about 6 peak sun hours per day. A typical 8 kW residential system in Tempe produces roughly 13,500-14,500 kWh per year — enough to offset most of a typical household’s electricity use.
