Scottsdale, Mesa, and Gilbert sit in the heart of Arizona's East Valley — one of the most solar-dense markets in the country. Despite being geographic neighbors, these three cities have meaningful differences in utility territory, HOA prevalence, roof types, and installer pricing that affect what you'll pay for solar and how much you'll save.
This guide covers the specifics of each city. For statewide pricing context and the full cost breakdown by system size, see our complete Arizona solar cost guide. To see how incentives reduce your net cost, review our Arizona solar incentives overview.
Who's Your Utility? It Changes Everything
The biggest variable for East Valley solar customers is which utility serves your address — because APS and SRP have different rate structures that affect your savings significantly.
| City | Primary Utility | Export Rate | Demand Charges? |
|---|---|---|---|
| Scottsdale | APS (most areas) | ~$0.068/kWh | Optional plan only |
| Mesa | SRP (most areas) | ~$0.065/kWh | Yes — E-27 plan |
| Gilbert | SRP (most areas) | ~$0.065/kWh | Yes — E-27 plan |
| Chandler | APS or SRP (split) | Varies | Varies |
Always verify your utility on your monthly bill before evaluating solar proposals. An installer quoting APS savings to an SRP customer (or vice versa) is giving you meaningless numbers.
Solar Costs in Scottsdale (APS Territory)
Scottsdale is primarily an APS territory, which means the net billing model ($0.068/kWh export credit) applies. Scottsdale also has the highest concentration of premium homes, tile roofs, and HOA-governed communities in the East Valley — all of which can affect installation costs.
Scottsdale Pricing (2026)
| System Size | Gross Cost | After Federal ITC | After ITC + AZ Credit |
|---|---|---|---|
| 6 kW | $12,780 | $8,946 | $7,946 |
| 8 kW | $17,040 | $11,928 | $10,928 |
| 10 kW | $21,300 | $14,910 | $13,910 |
| 12 kW | $25,560 | $17,892 | $16,892 |
Scottsdale pricing runs approximately $2.10–$2.20/W installed — slightly above the Phoenix metro average due to more complex tile roof installations and higher overhead costs in premium zip codes.
Scottsdale-Specific Considerations
- Tile roofs: Very common in Scottsdale. Installation on S-tile or flat concrete tile costs $300–$800 more than shingle and requires specialized mounting hardware.
- HOAs: Scottsdale has hundreds of HOA-governed communities. Arizona law protects your right to install solar, but HOAs can require specific equipment placement and aesthetics. Budget extra time for HOA approval.
- Summer bills: Scottsdale air conditioning loads are among the highest in the metro — $300–$450/month in July/August is common. This makes solar ROI excellent for properly sized systems.
Solar Costs in Mesa (SRP Territory)
Most of Mesa is served by SRP, which means the E-27 demand charge plan. Mesa is one of the largest solar markets in Arizona — high installer competition keeps pricing competitive, often $2.05–$2.15/W installed.
Mesa SRP Solar Considerations
- Demand charges are the key variable: SRP's demand charge (based on your peak 15-minute consumption during 2–8 PM weekdays) can significantly affect net savings. See our SRP solar plan guide for details.
- Battery value is high: For Mesa homeowners on SRP's E-27 plan, a home battery can reduce demand charges and shift solar production into peak hours — often adding $1,500–$3,000 in annual savings.
- System sizing: Don't oversize for SRP — exports at $0.065/kWh are less valuable than self-consumption at retail rates. Optimal: size to cover 85–95% of annual consumption.
Solar Costs in Gilbert (SRP Territory)
Gilbert is almost entirely SRP territory and shares the same rate structure as Mesa. Gilbert's newer housing stock means newer roofs (more installation-friendly) and fewer mature trees (more solar-friendly shade profiles) than older metro neighborhoods.
Gilbert-Specific Notes
- Newer homes: Many Gilbert homes built after 2005 have newer electrical panels (200A) and attic configurations that make solar installation more straightforward — potentially lower labor cost.
- HOAs: Gilbert has active HOA communities, particularly in master-planned areas. Your HOA cannot deny solar but can regulate aesthetics within limits.
- Roof orientation: Gilbert's newer subdivisions often have less-than-ideal south-facing roof space due to street grid orientation — an installer should do a shading and orientation analysis before sizing your system.

Calculate My Savings →Real Example: Mesa SRP vs Scottsdale APS (8 kW)
| Factor | Mesa (SRP) | Scottsdale (APS) |

| System cost (gross) | $17,040 | $17,040 |
| Net after all credits | $10,928 | $10,928 |
| Export rate | $0.065/kWh | $0.068/kWh |
| Demand charges? | Yes | No (standard plan) |
| Battery ROI | Very high | High |
| 25-yr savings (no battery) | ~$30,000–$36,000 | ~$34,000–$40,000 |
HOA Solar Rights in All Three Cities
Arizona law (A.R.S. § 33-1816) prohibits HOAs from outright banning solar. However, they can require:
- Panels not visible from the street (may not be enforceable in all cases)
- Approval of panel color or placement
- Written approval process (typically 30–60 days)
Build HOA approval time into your project timeline. For more on your rights, see our Arizona HOA solar rights guide.
What Affects Your Final Price in the East Valley
- Roof type: Tile adds cost vs. composition shingle
- Electrical panel age: Homes with 100A panels may need a main panel upgrade ($1,500–$3,500)
- System size: Larger systems have a lower per-watt cost
- Equipment tier: Premium panels and microinverters vs. budget string inverter setups
- Tree shading: Heavily shaded roofs may require microinverters or power optimizers
- Battery addition: Adds $9,000–$15,000 gross ($6,300–$10,500 after federal ITC)
