Going Solar in Gilbert AZ: SRP Territory Explained and What Homeowners Are Saving

Gilbert, Arizona sits almost entirely within SRP (Salt River Project) service territory, and that single fact shapes every solar calculation for homeowners here. With Gilbert now home to more than 270,000 residents and ranking among the fastest-growing cities in the country, the question is not whether solar makes sense but how the SRP rate structure affects what homeowners actually save.

This guide breaks down how SRP's solar billing works, what real savings look like for Gilbert homes, and why the prepaid lease model has become one of the cleanest options for homeowners who missed the 2025 federal tax credit window. If you want a fast estimate before reading further, the Solar Calculator runs the numbers in minutes based on your actual bill.

Gilbert Is Almost Entirely SRP Territory

Unlike neighboring Chandler, which straddles both APS and SRP service areas, Gilbert is covered almost exclusively by SRP. If you own a home in San Tan Ranch, Cooley Station, Morrison Ranch, Val Vista Lakes, or virtually any other Gilbert neighborhood, SRP is your utility and your solar savings story runs through their rate plans.

This matters because APS and SRP handle solar billing very differently. APS customers operate under net billing arrangements that changed significantly after 2023. SRP, meanwhile, offers the Solar Price Plan, which governs how solar customers generate, export, and receive credit for the electricity their panels produce. Understanding the distinction is the first step toward knowing what your Gilbert solar investment will actually return. Our full breakdown of how solar works under SRP versus APS covers the billing mechanics in detail if you want to go deeper on the comparison.

How SRP's Solar Price Plan Works

When a Gilbert homeowner installs solar through SRP, they move to SRP's Solar Price Plan. This plan uses time-of-use pricing, which means what you pay for electricity, and what you earn for excess generation, varies by the hour.

The on-peak window under SRP's current rate structure runs from 4 PM to 9 PM on weekdays. That is when electricity costs the most, and also when solar panels have typically already done most of their work for the day. By contrast, the hours between 9 AM and 3 PM are mid-peak, which is the production sweet spot for rooftop solar in Gilbert's climate.

The export credit rate, what SRP pays homeowners for excess solar sent back to the grid, is currently set below the full retail rate. This is the same transition that has happened at utilities across Arizona and the country. It means the highest financial return from solar in Gilbert comes from using as much of your own production as possible rather than exporting it.

A properly sized system for a 2,200 square foot Gilbert home, which typically carries a summer SRP bill between $220 and $320, can offset 80 to 90 percent of that usage during peak production months. The math becomes even stronger when you factor in that SRP's rates have increased each of the past several years and show no signs of reversing.

What Gilbert Homeowners Are Actually Saving

Gilbert's position in the East Valley puts it in one of the best solar production zones in the country. With approximately 299 sunny days per year and average peak sun hours ranging from 5.8 to 6.5 daily, systems here consistently outperform projections built on national averages.

A typical 8 to 10 kilowatt system on a Gilbert home produces roughly 13,000 to 16,000 kilowatt-hours annually. At current SRP rates, that translates to $1,300 to $1,800 in annual savings for a homeowner who previously paid an average bill of $150 to $200 per month, and significantly more for higher-usage households with pools, EVs, or large square footage.

Over a 25-year panel life, those savings compound. SRP has followed a consistent pattern of rate increases in recent years, and each increase adds to the return on a system that was priced before those increases hit. Locking in your production cost now means every future rate hike works in your favor rather than against you.

The Prepaid Solar Lease and the 30% Discount

One question Gilbert homeowners frequently ask is how to get solar at a meaningful discount without taking on a loan or a lien on the property. The prepaid solar lease is the answer, and it is the primary financing structure Phoenix Valley Solar uses for clients in SRP territory.

Here is how it works: instead of financing a purchase over 20 to 25 years and paying interest, the homeowner prepays the full lease term at a 30 percent discount off the standard purchase price. There is no loan, no lien, and no debt. The panels are installed by a vetted local installer. The homeowner uses the electricity those panels produce, and the savings show up directly on the monthly SRP bill.

For homeowners who missed the 2025 federal solar tax credit, the prepaid lease delivers the same 30 percent cost reduction through a different mechanism. The lower upfront price reflects the economics of the lease structure rather than a tax credit, so the discount stands regardless of your tax liability or filing situation.

The Solar Price Plan pairs well with the prepaid lease because the savings come primarily from production offset rather than export credits. A Gilbert household that consumes most of its solar output during mid-peak hours is capturing maximum value under SRP's billing structure. For a full comparison of the prepaid lease against a traditional loan, this breakdown explains the key differences.

Solar in Gilbert Neighborhoods: What to Expect by Area

Gilbert is a city of diverse home stock, from newer construction in Power Ranch and Trilogy at Power Ranch to mid-vintage homes in the Val Vista corridor. Roof type, age, and orientation vary significantly across these neighborhoods, and all of it affects what your system will look like and produce.

Power Ranch and Trilogy homeowners typically have concrete tile roofs. Tile requires specific mounting hardware that adds a minor cost but is otherwise excellent for solar. Most homes in these communities face east-west, which means some production loss compared to a south-facing roof, but modern system designs compensate through additional panel count.

Val Vista Lakes and San Tan Ranch tend to have larger square footage and, in many cases, pools. A home running a pool pump on SRP's grid adds roughly $50 to $80 per month in summer. Solar offsets that cost directly, making the savings case stronger for homeowners in these neighborhoods.

Newer master-planned communities along the Higley corridor and in Morrison Ranch often sit in HOA-governed neighborhoods. Arizona law protects the right to install solar regardless of HOA rules. An HOA cannot block an installation, though placement and aesthetics may be subject to reasonable guidelines. If your Gilbert HOA has raised questions about solar, the Contact page is the fastest way to get answers specific to your community.

Cooley Station and Agritopia are newer urban-style developments with a mix of rooftop types and orientations, including townhomes and smaller-footprint homes. A proper site assessment matters in these neighborhoods because shading from adjacent structures can affect production in ways a general estimate will not catch.

Nearby East Valley Cities and How They Compare

Gilbert homeowners often compare notes with neighbors in Chandler, Mesa, or Queen Creek. That comparison can get confusing because the utility territory changes significantly across the East Valley.

Chandler straddles both APS and SRP. If your Chandler neighbor is on APS, their solar billing structure and credit rates differ from yours as a Gilbert SRP customer. Mesa is split even further, with APS serving the western portion and SRP serving the east. Queen Creek, like Gilbert, sits almost entirely in SRP territory, so savings projections for Queen Creek homes are directly comparable to Gilbert's.

The consistent thread across all four cities is production volume. The East Valley's sun hours rank among the highest in the country, and that physical reality underpins every savings calculation regardless of which utility manages the billing. If you are in any of these cities, the About page explains how Phoenix Valley Solar works with homeowners across the region.

How to Find the Right Solar Company in Arizona for a Gilbert Home

Searching for solar companies in Arizona from Gilbert returns hundreds of results, most of which are national installers with no specific knowledge of Gilbert's neighborhoods, SRP's rate plans, or the Maricopa County permit process.

Phoenix Valley Solar operates as a solar broker rather than an installer. Instead of being tied to one installer's pricing and one product line, PVS sources competitive bids from multiple vetted local installers and presents the best option for each homeowner's specific roof and usage profile. That process costs the homeowner nothing extra compared to going directly to a single installer, and it protects against the most common pricing and installation mistakes in the market.

The broker model is particularly useful in SRP territory because system sizing for an SRP customer requires understanding how production and export credits interact under the Solar Price Plan. Getting that wrong means leaving money on the table every month for the life of the system.

Frequently Asked Questions

Are solar panels worth it in Gilbert, Arizona?

Yes. Gilbert's location in the East Valley puts it in one of the strongest solar production zones in the United States. With 299 or more sunny days per year and peak sun hours averaging 5.8 to 6.5 daily, a properly sized system typically offsets 80 to 90 percent of annual electricity costs under SRP's Solar Price Plan.

Does Gilbert AZ use APS or SRP for electricity?

Gilbert is almost entirely SRP (Salt River Project) territory. Unlike Chandler, which straddles both APS and SRP service areas, virtually all Gilbert homes fall under SRP. Your utility is confirmed on your monthly bill or through SRP's service territory map online.

How does SRP's solar rate plan work for homeowners who go solar?

SRP solar customers move to the Solar Price Plan, which uses time-of-use pricing. Electricity costs more during on-peak hours (4 PM to 9 PM weekdays) and less during off-peak hours. Solar panels produce most of their electricity during mid-peak hours, which reduces consumption during those windows. Excess electricity exported to the grid earns a credit at a rate currently set below the full retail price.

What is a prepaid solar lease and how does it work in SRP territory?

A prepaid solar lease lets Gilbert homeowners pay a single upfront cost at a 30 percent discount compared to a standard purchase price. There is no loan, no lien, and no monthly financing payment. The homeowner uses the electricity the panels produce, and the savings appear on the monthly SRP bill. For homeowners who missed the 2025 federal solar tax credit, the prepaid lease delivers the same financial discount through a different mechanism.

How do I find the best solar companies in Arizona near Gilbert?

The most reliable approach is to work with a licensed solar broker who can source multiple installer quotes on your behalf rather than committing to a single company's pricing. Look for contractors licensed with the Arizona Registrar of Contractors, confirmed warranties on both panels and workmanship, and a clear breakdown of production estimates based on your actual roof and usage. Phoenix Valley Solar works with Gilbert homeowners through the broker model at no additional cost compared to going direct.
