Solar in Long Beach: Complete 2026 Guide

Long Beach offers excellent solar conditions in Southern California, but under NEM 3.0, batteries are now essential for good economics. With SCE's high rates, solar + storage still delivers strong returns.

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 Reality in 2026
Long Beach averages 5.5 peak sun hours with 280+ sunny days. At $0.30/kWh or higher, SCE rates are among the nation's highest. Under NEM 3.0, solar export credits are reduced—but solar + battery systems still achieve 8-11 year paybacks. (Source: NREL Solar Resource Data)

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
The NEM 3.0 Math
Under NEM 3.0, exporting solar earns ~$0.05/kWh while you pay ~$0.30/kWh to buy back. That's an 85% loss! Batteries let you store midday solar and use it during expensive evening hours, capturing the full $0.30+ value. (Source: utility tariff filings and DSIRE Database)

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 TypeFederal CreditNotes
Cash/Loan PurchaseNone (0%)25D residential credit ended Dec 31, 2025
PPA/Lease30% (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
Battery Incentives Matter
California's SGIP (Self-Generation Incentive Program) provides rebates for battery storage. Combined with NEM 3.0's economics that favor batteries, this makes storage financially attractive in Long Beach. (Source: utility tariff filings and DSIRE Database)

Costs & Savings

Average System Costs (2026)

System SizeSolar OnlySolar + 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
The New Solar Equation
In Long Beach under NEM 3.0, a 7kW solar-only system might save $1,500/year. Add a battery and that jumps to $3,000+/year. The battery pays for itself by capturing value that would otherwise be lost. (Source: EnergySage market analysis)

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
