Cost Per Watt

  • Glendale average: $2.30-2.90 per watt
  • Budget installs: $2.10-2.30 per watt
  • Premium installs: $2.90-3.50 per watt

Arizona's mature solar market means competitive pricing. The Phoenix metro area has some of the lowest per-watt costs in the nation.

Payback Period

At $0.12/kWh average electricity rates (with higher summer peak rates), Glendale homeowners typically see 10-13 year payback periods. High summer production and high summer rates accelerate returns.

APS Service & Programs

Glendale is served by Arizona Public Service (APS), the state's largest electric utility. APS has specific programs and rate structures for solar customers that significantly impact economics.

APS Solar Programs

  • Net billing: Export credits at wholesale rates
  • Self-consumption: Best value from using your own power
  • Demand charges: May apply on some rate plans
  • Time-of-use: Required for solar customers
APS Rate Structure
APS solar customers are on time-of-use rates. On-peak hours (3-8 PM summer) have highest rates, which occurs as solar production winds down. Battery storage can help shift solar to peak hours for maximum value. (Source: manufacturer specifications and EnergySage data)

APS Time-of-Use Rates

Period (Summer)Approximate RateSolar Impact
On-peak (3-8 PM)$0.20-0.25+/kWhPeak starts as solar fades
Off-peak (8 PM-3 PM)$0.08-0.10/kWhMost solar production
Super off-peak$0.05-0.07/kWhNight/early morning

Arizona Incentives

Available Incentives

  • Property tax exemption: Solar value excluded from property tax
  • Sales tax exemption: No sales tax on solar equipment
  • State tax credit: Arizona offers a 25% credit up to $1,000
  • Net billing: Export credits (at reduced rates)

Arizona State Tax Credit

Arizona offers a 25% state tax credit for solar installations, capped at $1,000. While modest, this helps offset costs slightly for purchased systems.

Federal Options

  • Purchased systems: No federal credit (25D ended 2025)
  • PPA/Lease: Still benefits from 30% credit through 2027
  • Arizona market: Both purchase and PPA remain competitive

Glendale Considerations

Climate Factors

  • Extreme heat: 110°F+ days reduce panel efficiency
  • Heat penalty: 10-20% summer production loss from heat
  • Dust: Desert dust requires periodic cleaning
  • Monsoon season: Summer storms provide natural cleaning

Glendale-Specific Factors

  • HOAs: Arizona law protects solar rights in HOAs
  • Tile roofs: Common; slightly higher installation cost
  • Pool pumps: Run during solar hours for maximum savings
  • Battery value: TOU rates make batteries more attractive

Production Estimates

  • Annual production: 1,650-1,850 kWh per kW installed
  • 8 kW system: ~13,200-14,800 kWh/year
  • Best months: March-May, September-October
  • Summer note: Longest days but heat reduces efficiency
Heat-Tolerant Panels
