Going Solar with TEP in 2026
A complete guide for Tucson Electric Power customers — how TEP's Solar Connect program works, how to qualify for the Energy Storage Rewards program, what the interconnection process looks like, and what to look for in a TEP-experienced installer.
Last updated: June 2026
What TEP customers should know in 2026
The federal 30% solar tax credit expired December 31, 2025. TEP operates its own solar program (Solar Connect) with net billing rather than net metering. The standout TEP advantage in 2026 is the Energy Storage Rewards program — approximately $720/year in bill credits for qualifying battery installations — making Tucson one of the stronger markets for solar-plus-storage in Arizona.

TEP Service Area
Tucson Electric Power serves the greater Tucson metro area. If your electricity bill says TEP, this guide applies to you.
Outside the Tucson metro? Most Phoenix metro homeowners are served by APS or SRP.
How TEP Solar Connect Works
TEP's Solar Connect program governs how your solar system connects to the grid and how your excess generation is credited. Like APS and SRP, TEP moved away from retail-rate net metering — your exported solar earns a credit at TEP's avoided-cost rate, which is below what you pay for grid electricity.
| Rate Type | Rate (2026) | What It Means |
|---|---|---|
| TEP retail rate | ~$0.12–0.14/kWh | What you pay when drawing from the grid |
| TEP export credit (Solar Connect) | ~$0.057/kWh | What TEP credits for surplus solar |
How this compares in Arizona:TEP's export rate (~$0.057/kWh) sits between APS ($0.0617/kWh) and SRP ($0.0345/kWh). Self-consumption is still more valuable than export — a well-designed system minimizes what you send to the grid — but TEP's rate is more favorable than SRP's for customers who do export.
TEP Energy Storage Rewards Program
This is the most compelling solar incentive unique to TEP customers. The Energy Storage Rewards program pays eligible homeowners approximately $720 per year in bill credits for installing a qualifying battery storage system.
How it works
You install a qualifying battery, enroll in the program, and allow TEP to remotely dispatch the battery during high-demand events (typically peak summer afternoons). In exchange, TEP credits your bill approximately $720/year. You keep full control during most hours — TEP's dispatch events are limited in duration.
Battery eligibility
Not every battery qualifies. The system must meet TEP's capacity and communication requirements. Common qualifying options include Enphase IQ Battery, Tesla Powerwall, and SolarEdge Energy Bank — but confirm current eligibility with your installer before signing, as TEP updates its approved equipment list.
The financial case
At ~$720/year, the Energy Storage Rewards credit reduces the effective payback period on a battery by 2–3 years in most Tucson installations. Combined with the time-of-use value of storing midday solar for the 3pm–8pm peak window, battery storage makes stronger economic sense for TEP customers than almost anywhere else in Arizona.
Before you sign:Ask every installer whether the battery they're proposing is currently eligible for TEP's Energy Storage Rewards program and whether they've completed Energy Storage Rewards enrollments before. Eligibility requirements change — you want an installer who has done this recently, not one reading the requirements for the first time.
What to Look for in a TEP Solar Installer
Tucson's solar market is smaller than the Phoenix metro, which means fewer installers have deep TEP experience. These are the things worth confirming before you commit.
Solar Connect experience
Ask how many TEP Solar Connect interconnections they've completed in the past 12 months. TEP has specific application requirements — experienced companies get fewer delays.
Energy Storage Rewards expertise
If you want the ~$720/yr credit, confirm the installer has enrolled customers in Energy Storage Rewards before and knows which batteries currently qualify.
Tucson-specific system design
Tucson averages 299 sunny days per year and peak sun hours differ from Phoenix. A good proposal should use Tucson irradiance data, not statewide averages.
NABCEP + ROC license
Required in Arizona regardless of utility. Verify the ROC license at roc.az.gov and look for NABCEP certification on their profile or proposal.
