California State Incentives

California NEM 3.0 net billing; SGIP battery rebates up to $1,000/kWh

Net Metering: Southern California Edison (SCE)

JouleIO's planning data marks net metering or a solar export credit as available for Southern California Edison (SCE) customers in Long Beach. Export credits can be at retail or below-retail rates depending on the current tariff, so confirm terms with the utility that serves your address.

Solar Energy in Long Beach, California

Long Beach, California receives an average of 6.3 peak sun hours per day, placing it among the best cities in the country for solar energy production. With a planning electricity rate of 33.5¢ per kWh (EIA California residential average for 2026-06: 34.74¢; U.S. average 18.34¢), above the national average, solar savings potential is stronger.

A typical 6kW solar system in Long Beach produces approximately 11,038 kWh per year, saving homeowners an estimated $1,733 annually. The system pays for itself in about 10.1 years, after which you enjoy essentially free electricity for the remaining 15+ years of the system's warranty life.

JouleIO's dataset carries a modeled solar-adoption value of 9.1% for Long Beach. It is a rough planning placeholder, not a measured count of local installations, so use utility interconnection data or installer quotes if local adoption matters to your decision.

Methodology & Solar Data Sources for Long Beach

How we calculate Long Beach solar potential and savings: Annual production = system kW × estimated peak sun hours × 365 × 0.80 system derate × a roof-orientation factor. This is a simplified planning formula, not a PVWatts run for your address. Cost uses a planning price per watt for California, and bill savings use a planning electricity rate of 33.5¢/kWh (the EIA California residential average for 2026-06 is 34.74¢/kWh).

  1. Peak sun hours for Long Beach (6.3/day) are a planning estimate in the typical range for California, not a site-specific NREL NSRDB value. Enter your address in NREL PVWatts for a location-specific production estimate.
  2. System sizing defaults to a 6kW residential rooftop system with roughly 400W panels; adjust the size and monthly bill to match your home.
  3. Federal tax credit: modeled as 0% for 2026 residential installations because IRS guidance says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025.
  4. Exports are discounted rather than credited 1:1 at retail, because many utilities have shifted to net billing or avoided-cost export rates. Verify your utility's current tariff.
  5. 25-year savings assume a 2.5% annual electricity-rate increase and do not subtract panel degradation, inverter replacement, or maintenance.

Authoritative US solar data sources:

Solar Disclaimer: Solar savings vary based on roof orientation, shading, system quality, installer markup, financing terms, utility rate plan, and policy changes. Always get 3+ quotes from NABCEP-certified installers and review contracts carefully. Tax credit eligibility depends on tax liability, consult a tax professional.
