Arizona solar / Tempe
In Tempe, roof control comes before solar math
Written by the Solar Learning Lab research deskUpdated August 22, 202610 min read
Tempe's rooftop-solar constraint is not sunlight or a utility form. It is tenure. The city's owner-occupancy rate is 42.3 percent, which means most residents cannot put panels on a roof they own. That hard limit should lead the page. A renter may care deeply about clean energy and high bills, but a personal rooftop purchase requires an owner, a landlord or a building-level decision.
For the owner households that can decide, Tempe pairs a $538 flat PV permit with a city climate program that has real dates: 100 percent renewable municipal energy by 2035 and community carbon neutrality by 2050.
Start with who controls the roof
Homeowners can model a system. Renters should start with a landlord, building manager or shared-building energy conversation.

The renter truth is a product constraint, not an awkward footnote
QuickFacts puts Tempe at 42.3 percent owner occupancy for 2020 through 2024, versus 57.2 percent in Glendale and 76.0 percent in Peoria. Median gross rent is $1,743, and the city reports 78,279 households. Those facts should change the opening question. Before comparing inverter brands, ask whether the reader has the legal and practical authority to make a long-term roof alteration. Most Tempe residents do not. Read Tempe's housing profile.
That does not make renters irrelevant to the energy conversation. It means the route is different: ask a landlord or property manager what they control, check whether a building has an existing solar or renewable-energy program, and distinguish a retail electricity concern from a privately owned roof asset. Tempe's Energy Resource Hub lists SRP Solar Choice as a no-equipment renewable option and points residents to consumer resources. A renter should not be pushed into a homeowner financing script just because the city is sunny. Explore the city energy hub.
Homeowners have their own constraints. Tempe's cited profile shows a $455,400 median value for owner-occupied homes, $1,828 median monthly owner cost with a mortgage and $79,663 median household income. The right owner question is whether the roof, panel, planned move horizon and usage pattern support a system. Ownership opens the door. It does not settle the purchase. See the owner data.
Tempe is the one city here with dated public energy goals
Tempe says its municipal operations are targeting carbon neutrality with 100 percent renewable energy by 2035. It also sets a community carbon-neutrality goal for 2050 with equitable outcomes. The city tracks community energy emissions as electricity used in residential, commercial and industrial spaces. These are concrete civic goals, not a generic sustainability phrase, and they make Tempe distinct from the other two cities in this group. Read Tempe's performance measures.
The city's Sustainability and Resilience Division was formed in 2018 and is guided by a 2022 Climate Action Plan Update. Its role matters because the same city division that frames the targets also says Tempe partners with SolarAPP+ to fast-track residential solar permits. That connection is useful context. It is not a promise that every address, building type or project scope will receive an automatic approval. Read the division statement.
The highest permit in the group deserves a visible line item
Tempe's adopted Table 2-A lists a $538 flat fee for a single-family photovoltaic system, up from a prior $494. The city's Building Safety page says the 2025 through 2026 fee schedule became effective July 1, 2025 after the council-approved annual CPI adjustment. That is roughly 1.8 times Glendale's $305.66 published base total and 2.9 times Peoria's $184 simple-PV fee. Tempe owners do not need to dramatize that cost, but they should not let it disappear into a vague "permits included" line. Open the Tempe PV fee table.
Tempe requires online permit applications through its Citizen Access Portal and electronic residential plan submission. The reviewed city pages do not publish a residential solar review timeline. They also describe a residential rebate program under which a homeowner may qualify for a building-permit-fee rebate after final inspection, but the pages reviewed do not state eligible improvements or confirm that rooftop PV qualifies. Call that n.a. until the city confirms the actual program. See the permit entry point.
SolarAPP+ is confirmed. The operating details are not.
Tempe's Sustainability and Resilience Division states: "Tempe partners with SolarAPP+ to fast-track Residential solar permits." That is enough to say the partnership exists. The Building Safety residential plan-review and application pages reviewed for this guide do not describe qualifying project types, the workflow, a processing fee or a solar review clock. The honest line is narrower than a contractor slogan: SolarAPP+ is a city-confirmed partnership, while address-level eligibility and timing remain n.a. from the fetched Building Safety material. Read the partnership statement and the residential review page.
That gap gives an owner a useful question for every bidder: which city page or portal message confirms this exact project will use the fast-track route? A written answer is better than a verbal assurance, especially when the permit is $538 and related battery or electrical scope may change the submittal. Review Tempe Building Safety fees.
Tempe is mostly an SRP conversation, but the bill still has the last word
Tempe city resources list both SRP and APS. The city's new-resident directory even lists local addresses for both providers, and the Energy Resource Hub links residents to both SRP and APS installer resources. No fetched source assigns every Tempe neighborhood to one provider. SRP is the dominant practical context, not a license to skip the account check. See Tempe's utility resources.
| Energy source | Type | Average price | What that means |
|---|---|---|---|
| SRP | 2024 utilitywide average | 13.46¢ per kWh | Useful benchmark, not a current account price. |
| APS | 2024 utilitywide average | 16.45¢ per kWh | Relevant in APS pockets only. |
| Tempe solar | Planning rule | self-use first not a rate | Verify provider and plan on the bill. |
SRP offers Customer Generation and Average Demand with net metering, plus export-rate plans. That is enough detail for a Tempe homeowner to insist on a named plan. The export pages cite 3.45 cents per kWh, while the SRP rooftop page says $0.0187 for the export-plan group. Treat that as a source conflict and request the ratebook rather than spending this page on a generic plan tutorial. APS pockets face a reported 5.5-cent export rate for new solar customers after the August 2026 ACC reduction. See SRP's plans, the SRP rooftop page and APS coverage.
The model is strong. It cannot solve the tenure problem.
May has the largest monthly output in the fixed model.
PVGIS v5.2. PVGIS v5.2 model run by Solar Learning Lab on August 22, 2026, NSRDB radiation database. Fixed south facing mount, 30 degree tilt, 14 percent losses, downtown Tempe coordinates. Your roof will differ.
PVGIS estimates 1,800.9 kWh per kW each year in this city-coordinate run, with May at 172.9 kWh per kW. TEMPE ASU's climate normal reports 5,774 cooling degree days at base 57; nearby Sky Harbor reports 7,021.3. Those numbers say summer load deserves attention. They do not reveal whether a renter owns the roof, whether an owner's roof is shaded, or when the household actually uses electricity. The model is a homeowner tool only after roof control has been established. Read the climate-normal query.
Do not hand renter economics to a provider or a landlord by accident
Arizona's solar-device credit is 25 percent of qualifying cost up to a $1,000 cumulative residential cap, with up to five years of carryforward. It belongs to an individual who installs a device in the taxpayer's Arizona residence, subject to the statute. It is not a renter's benefit when the landlord owns the equipment. The federal residential 25D credit ended December 31, 2025; a lease or PPA provider may claim 48E. These ownership distinctions are basic, but Tempe's tenure profile makes them unusually important. Read the Arizona statute and the federal update.
SRP customers can investigate a limited-time $250 demand-management-system offer and a $0.005 per kWh REC purchase program. Tempe also references the SRP Economy Price Plan for limited-income customers but does not state the discount amount. Those programs should be evaluated by the account holder. They are not a substitute for a clear ownership agreement in a rental building. See SRP's rebate page and Tempe's resource hub.
Use Tempe installer ratings to ask better ownership questions
The directory is a starting point, not a recommendation. For a Tempe homeowner, ask whether the bid includes the $538 permit, how it handles the SolarAPP+ evidence gap and which SRP or APS plan it models. For a renter, the first installer question may be whether the company works with property owners and whether the person receiving the proposal has authority to approve a roof project. The same equipment list is not the same project when the building owner and bill payer differ.

A lease or PPA provider may claim federal 48E. That is provider tax treatment, not a homeowner cash credit. Confirm the rate escalator, term and utility assumptions.
Estimates, not quotes. Inputs use Arizona's EIA state rate baseline, EnergySage Arizona cost data and our city PVGIS run. A Tempe address can be SRP or APS, so a real proposal needs the bill and the current utility plan. We are a solar installer and we also partner with other solar companies. See our disclosures.
