AZ Energy Hub is independently published by Evan J. — not an installer, not a salesperson, not a certified energy professional. Evan is an Arizona homeowner who has been an APS, SRP, and now ED3 customer, which means every rate plan and utility program covered on this site is something he has either paid for personally or has first-hand experience comparing.
Articles and calculators are researched and drafted with AI assistance against publicly available sources (APS and SRP rate schedules, NREL PVWatts, DSIRE, manufacturer spec sheets) and reviewed before publishing. When a claim is based on those sources rather than personal testing, we say so.
We earn affiliate commissions when readers buy through our links and will show display ads on article pages. Neither changes which products we cover or what the calculators output. If a recommendation ever feels sales-y, it's a mistake — email us via the contact section below.
Our Mission
AZ Energy Hub publishes free, accurate, and unbiased solar, battery, and utility-rate calculators built specifically for Arizona households. Our calculators cover the three big utilities (APS, SRP, ED3) plus the smaller co-ops most national tools ignore, with real current rate schedules, current federal and state incentives, and Arizona-specific data like peak sun hours and the heat-degradation factors that punish underspec'd systems in 115°F summers.
The goal is simple: give Arizona homeowners and renters the real numbers so they can make informed decisions about solar panels, battery storage, EV charging, time-of-use plan switches, and Virtual Power Plant (VPP) participation — without a sales pitch attached.
Why We Built This
Most solar calculators online use national averages and outdated incentive data. Arizona homeowners deserve tools that reflect their reality: 6.5 peak sun hours, extreme summer heat degradation, the specific TOU windows on APS Saver Choice Plus and SRP E-27, the ED3 Saver Choice equivalent for Maricopa, and the current incentive landscape where the federal solar ITC has expired but the battery ITC remains at 30% through 2032.
We're especially focused on Virtual Power Plant (VPP) programs. APS pays homeowners $150-$500/year to dispatch stored battery energy during peak grid demand. This turns your battery from a backup device into an income-generating asset, and almost no national publisher walks Arizona homeowners through the enrollment math.
Why Maricopa and ED3 Get Special Attention
Most Arizona energy coverage stops at “APS or SRP” and ignores everyone else. But hundreds of thousands of Arizonans live outside those two service areas: ED3 (Maricopa), TEP (Tucson), UNS Electric, Mohave Electric, Sulphur Springs Valley Electric, Trico, Navopache, and a dozen smaller co-ops. Their rates, peak windows, and rebate programs are completely different — and using an APS calculator on an ED3 bill produces wrong numbers.
Evan is an ED3 customer in Maricopa, which is why our coverage of that utility is unusually deep. The same approach (real published rates, real program documents, real math) extends to every Arizona utility we cover. If your utility isn't represented yet and you want it added, email us — that is how the SRP and ED3 coverage started.

Our Methodology
Every calculation on AZ Energy Hub is based on publicly available data and verifiable sources. We don't inflate savings estimates or hide costs. Here's how our calculators work:
- Solar production: We use the NREL PVWatts v8 API with your specific location, roof tilt, and panel orientation to estimate annual energy production.
- Rate calculations: We apply the actual APS Saver Choice Plus TOU rate schedule, including peak, off-peak, and super off-peak periods for both summer and winter.
- Incentives: We include the current Arizona state tax credit (25% up to $1,000), the APS Cool Reward rebate ($3,750 for batteries), and the 30% federal battery ITC.
- Degradation: We factor in 0.75%/year panel degradation (elevated for Arizona heat) and 2%/year battery capacity loss.
How We Make Money
Transparency matters. AZ Energy Hub is free to use and always will be. We earn revenue through two channels, both clearly disclosed on every page where they apply:
- Affiliate partnerships: When you click through to one of our merchant partners and make a purchase, we may earn a commission at no additional cost to you. Active partners as of April 2026: Jackery and EcoFlow (via Commission Junction), Renogy (via Impact), and Amazon Associates. Every affiliate link is labeled with a disclosure callout box, and every product recommendation card carries an “Affiliate link” notice. We never insert a buy-now button without disclosing the relationship.
- Display advertising: We are preparing to show relevant display ads via Google AdSense on article pages. Calculators will remain ad-free above the result.
Neither revenue source changes which products we cover or what the calculators output. We don't accept paid placements, sponsored posts, or “featured listing” arrangements. If a recommendation ever feels sales-y, that's a mistake worth telling us about.
