Solar in Chandler
Chandler is part of the Phoenix metropolitan area, enjoying exceptional desert sunshine. As an SRP (Salt River Project) service area, Chandler homeowners face unique solar considerations—particularly demand charges that can significantly impact solar economics.
Chandler Solar Reality
With 6.0 peak sun hours, Chandler has outstanding solar production potential. However, SRP's demand-based rate structure means solar economics depend heavily on system design and usage patterns. Battery storage often helps. (Source: NREL Solar Resource Data)

Chandler Solar Factors
- Exceptional sunshine: 6.0 peak sun hours daily
- Lower base rates: ~$0.12/kWh (but demand charges add up)
- SRP territory: Demand charges affect solar customers
- High summer usage: AC drives significant electricity bills
- Growing tech hub: Modern homes often solar-ready
Chandler Solar Costs
Average System Costs
| System Size | Gross Cost | After AZ Credit |
|---|---|---|
| 6 kW | $14,400-16,800 | $13,400-15,800 |
| 8 kW | $19,200-22,400 | $18,200-21,400 |
| 10 kW | $24,000-28,000 | $23,000-27,000 |
Federal 25D credit ended Dec 31, 2025. Arizona state credit (25% up to $1,000) still available.
Cost Per Watt
- Chandler average: $2.40-2.80 per watt
- Budget installs: $2.20-2.40 per watt
- Premium installs: $2.80-3.50 per watt
Payback Period
SRP demand charges significantly affect payback calculations:
- Without demand management: 12-16 years
- With battery/demand management: 11-14 years
- 25-year savings: $20,000-40,000+ depending on strategy
SRP Policies & Demand Charges
Salt River Project serves Chandler with rate structures that include demand charges—a critical factor for solar customers to understand.
Understanding SRP Demand Charges
- What they are: Charges based on your peak hourly usage
- When measured: Typically during on-peak hours (afternoons)
- Solar impact: One cloudy hour can set your demand charge
- Cost impact: Can be $30-100+ per month
SRP Demand Charge Challenge
Even with solar, one hour of high usage during peak time—like when clouds block your panels while AC runs—can set your demand charge for the month. This is why battery storage is often recommended for SRP customers. (Source: SRECTrade and state program data)
SRP Rate Options
| Plan Type | Best For | Demand Charges |
|---|---|---|
| Customer Generation | Solar homes | Yes, significant |
| Time-of-Use | Flexible usage | Some plans include |
| Standard | Non-solar homes | Lower or none |
Managing Demand Charges
- Battery storage: Cover peak hours when solar dips
- Load shifting: Run AC and appliances during off-peak
- System sizing: Match to actual usage patterns
- Smart thermostats: Pre-cool home before peak hours
Arizona Incentives
Available Incentives
- Arizona Residential Solar Tax Credit: 25% of cost, max $1,000
- Property tax exemption: 100% of solar value excluded
- Sales tax exemption: On solar equipment
- SRP programs: Check current battery incentives
Federal Options
- Purchased systems: No federal credit (25D ended 2025)
- PPA/Lease: Solar company claims 30% credit through 2027
- Net benefit: Lower PPA rates possible due to federal credit
Chandler Considerations
Desert Climate Factors
- Extreme heat: Summer temps reduce panel efficiency 10-15%
- Dust: Occasional cleaning improves production
- Monsoons: Brief but intense summer storms
- Abundant sunshine: Compensates for heat losses
Chandler-Specific Factors
- Tech corridor: Intel and tech companies bring solar-aware residents
- Master-planned communities: HOAs present but AZ protects solar rights
- Pool equipment: Run pumps during solar production hours
- EV charging: Solar can offset significant EV costs
Production Estimates
- Annual production: 1,700-1,900 kWh per kW installed
- 8 kW system: ~13,500-15,000 kWh/year
- Best months: April-June (before extreme heat)
- Winter production: 50-60% of peak
Chandler Production
Chandler's 6.0 peak sun hours mean exceptional production. An 8 kW system produces 13,500-15,000 kWh annually—outstanding by any measure. The challenge is capturing this value under SRP's rate structure. (Source: NREL Solar Resource Data)
The Bottom Line
Chandler has excellent solar resources but challenging utility policies. SRP's demand charges require careful planning, often including battery storage. With proper design, 11-14 year payback is achievable.
Key points:
- 6.0 peak sun hours—exceptional solar production potential
- SRP demand charges are a major factor in solar economics
- Battery storage often essential for maximizing value
- Arizona offers $1,000 state tax credit
- 11-14 year payback achievable with good system design
