Solar in Long Beach
Long Beach sits in Southern California Edison (SCE) territory with excellent sunshine and some of the nation's highest electricity rates. Under California's NEM 3.0 rules, the solar equation has changed—batteries are now essential for optimal economics.
Long Beach Solar Factors
- Excellent sunshine: 5.5 peak sun hours, 280+ sunny days
- Very high electricity rates: ~$0.30/kWh and climbing
- SCE territory: NEM 3.0 rules apply
- Batteries essential: Self-consumption now critical
- Time-of-use rates: Evening peak periods
SCE & NEM 3.0
Southern California Edison (SCE) serves Long Beach under California's NEM 3.0 net billing framework. This fundamentally changes solar economics from the old NEM 2.0 days.
How NEM 3.0 Changes Solar
- Lower export credits: Solar exports worth ~$0.05/kWh vs. retail
- Time-of-use critical: Export values vary by hour
- Self-consumption wins: Using solar directly saves $0.30+/kWh
- Batteries essential: Store midday solar for evening use
SCE Rate Structure
- Average rate: ~$0.30/kWh (varies by tier and time)
- Peak evening: 4pm-9pm highest rates ($0.35-0.50/kWh)
- Off-peak midday: When solar produces most, rates lowest
- Baseline allowance: Lower tier for basic usage
Incentives & Tax Credits
Federal Tax Credit (2026)
| Ownership Type | Federal Credit | Notes |
|---|---|---|
| Cash/Loan Purchase | None (0%) | 25D residential credit ended Dec 31, 2025 |
| PPA/Lease | 30% (to company) | 48E credit through Dec 31, 2027 |
The solar company claims the credit on leased systems and passes savings to you through lower rates.
California Incentives
- SGIP battery rebate: Self-Generation Incentive Program for storage
- Property tax exemption: California exempts solar from property tax
- No sales tax: On solar equipment
- DAC-SASH: Low-income programs available
Costs & Savings
Average System Costs (2026)
| System Size | Solar Only | Solar + Battery |
|---|---|---|
| 5 kW + 10 kWh battery | $14,000-17,000 | $24,000-30,000 |
| 7 kW + 13 kWh battery | $19,600-23,800 | $32,000-40,000 |
| 10 kW + 20 kWh battery | $28,000-34,000 | $45,000-55,000 |
No federal credit for purchased systems in 2026. SGIP rebates may reduce battery costs.
Production & Savings
- Annual production: 1,450-1,600 kWh per kW installed
- 7 kW system output: ~10,000-11,000 kWh/year
- Annual savings with battery: $2,500-3,500 at current rates
- Payback period: 8-11 years (solar + battery)
Why Batteries Change Everything
- Without battery: Lose 85%+ value on exports
- With battery: Capture full $0.30+/kWh value
- Evening shift: Use stored solar during 4-9pm peak
- Backup power: Protection during outages
System Sizing Strategy
- Size for self-consumption: Don't oversize for export
- Battery sizing: Cover evening peak usage
- Time-of-use optimization: Maximize value during expensive hours
- EV consideration: If you have an EV, size for that too
The Bottom Line
Long Beach solar is still excellent—but batteries are now essential. NEM 3.0 changed the economics, but SCE's extremely high rates mean solar + storage still delivers 8-11 year paybacks. Don't install solar without a battery in 2026.
Key considerations:
- Batteries are essential under NEM 3.0—not optional
- High SCE rates make solar savings substantial
- SGIP rebates help offset battery costs
- PPA/Lease option retains federal credit benefit
- Size for self-consumption, not export
- 8-11 year payback still excellent for California
