Solar in Irvine
Irvine is an affluent Orange County city with excellent solar conditions. The combination of abundant sunshine, high SCE electricity rates, and strong property values makes solar a compelling investment for Irvine homeowners.
Why Irvine is Good for Solar
- Excellent sunshine: 5.5 peak sun hours daily
- High electricity rates: SCE charges ~$0.30/kWh
- Affluent community: Higher home values, larger systems
- Time-of-use rates: Peak rates make self-consumption valuable
- Property values: Solar adds value to Irvine homes

Cost Per Watt
- Irvine average: $2.80-3.20 per watt
- Budget installs: $2.50-2.80 per watt
- Premium installs: $3.20-4.00 per watt
Payback Period
Despite NEM 3.0 changes, Irvine's high electricity rates support reasonable payback periods:
- Typical payback: 8-11 years
- With battery: Can improve economics with TOU optimization
- 25-year savings: $40,000-60,000+ depending on system size
SCE NEM 3.0
As an SCE (Southern California Edison) customer, Irvine residents are under California's NEM 3.0 policy, which significantly changed solar economics in April 2023.
NEM 3.0 Key Points
- Export values reduced: ~75% lower than NEM 2.0
- Time-of-use matters: Export value varies by time of day
- Self-consumption key: Using power directly saves more
- Batteries recommended: Store daytime solar for evening use
SCE Time-of-Use Rates
| Time Period | Typical Rate | Solar Strategy |
|---|---|---|
| Off-peak (9pm-4pm) | $0.20-0.25/kWh | Solar produces during this window |
| Peak (4pm-9pm) | $0.40-0.50/kWh | Use battery power here |
California Incentives
Available Incentives
- No state tax credit: California doesn't offer one currently
- Property tax exemption: Solar excluded from property tax until 2025 (check current status)
- SGIP: Self-Generation Incentive Program for batteries (income-qualified)
- Local rebates: Check with SCE for current programs
Federal Options
- Purchased systems: No federal credit (25D ended 2025)
- PPA/Lease: Solar company claims 30% credit through 2027
- Net benefit: PPA rates may be lower due to federal credit
Irvine Considerations
HOA Considerations
- California Solar Rights Act: HOAs cannot unreasonably restrict solar
- Master-planned communities: Irvine has many—most allow solar
- Approval process: May need architectural review
- Placement rules: Some HOAs have specific guidelines
Irvine-Specific Factors
- Newer homes: Many have solar-ready electrical
- Tile roofs: Common in Irvine, slightly higher install costs
- Large homes: Higher usage means larger, more economical systems
- Coastal influence: Morning fog burns off quickly
Production Estimates
- Annual production: 1,500-1,700 kWh per kW installed
- 8 kW system: ~12,000-14,000 kWh/year
- Best months: May-September
- Winter production: 50-60% of peak
The Bottom Line
Irvine remains a good market for solar despite NEM 3.0. High electricity rates and abundant sunshine support 8-11 year payback periods. Battery storage is increasingly important for maximizing value.
Key points:
- High SCE rates ($0.30/kWh) make solar economically attractive
- NEM 3.0 favors self-consumption over export
- Battery storage improves economics significantly
- HOAs cannot unreasonably restrict solar in California
- 8-11 year typical payback with $40,000+ lifetime savings
