Solar Production in Redwood City

Redwood City receives 5 peak sun hours per day — slightly below the California average of 5.2. This is the key input that determines how much electricity your panels produce. More sun hours mean more kWh generated, which translates directly to a lower bill.

Production estimates use a 7kW system at 80% efficiency (accounting for inverter losses, shading, and temperature derating). Actual output depends on roof orientation, tilt, and shading.

NEM 3.0 and What It Means for Redwood City Solar

Since April 2023, all new California solar installations fall under NEM 3.0. The key change: export credits dropped from near-retail rates to roughly ~$0.05-0.08/kWh. This makes self-consumption — using your solar power as it is produced — far more valuable than exporting to the grid.

What still works well
  • - Daytime AC, appliances, EV charging offset at full retail rate
  • - Battery storage shifts evening usage off-grid
  • - Protection from future rate increases (71%+ over 10 years)
What changed
  • - Export credits: ~~$0.05-0.08/kWh (was near retail under NEM 2.0)
  • - Oversizing panels for export is less financially efficient
  • - Battery pairing is now more important than before

Solar Incentives for Redwood City Homeowners (2026)

  • ✓Net metering (NEM 3.0 in CA) — sell excess power back to your utility
  • ✓Federal Section 48E credit (commercial/PPA structures only — residential Section 25D expired Dec 31 2025)
  • ✓California Solar Rights Act — your HOA cannot legally block installation
  • ✓California property tax exclusion — solar system value excluded from assessment
  • ✓SGIP battery incentive — up to $1,000+ for battery storage (income-qualified programs available)

In 2026, Redwood City homeowners can benefit from: California's property tax exclusion for solar, the SGIP battery incentive, and the California Solar Rights Act (HOAs cannot block installation).
