Solar Investment Analysis
📈 Solar Payback Timeline
Great news! After 7.0 years, your solar system will generate pure savings of approximately $1,800/year for the remaining 15+ years of its warranty period.
⚖️ Understanding California's Net Metering 3.0
Net Metering 3.0 changes how excess solar energy is credited, with export rates around 75% of retail rates and time-of-use components. Battery storage becomes more valuable for self-consumption optimization.
Additional Information
California leads the nation in solar adoption with over 1.4 million solar installations powering homes and businesses. With some of the highest electricity rates in the country (averaging 22¢/kWh), excellent sun exposure (5.5+ peak sun hours), and strong state and federal incentives, solar power offers exceptional value for California homeowners.
Why solar makes sense in California
High electricity rates drive savings: California's average residential electricity rate of 22¢/kWh is among the highest in the nation, making every kilowatt-hour of solar generation more valuable than in most states.
Excellent solar resource: Most of California receives 5.5+ peak sun hours daily, providing optimal conditions for solar panel performance and energy production.
Strong policy support: California's commitment to renewable energy has created a robust solar market with experienced installers and competitive pricing.
Climate considerations: Solar panels perform well in California's climate, and the state's focus on sustainability aligns with solar adoption goals.

Net metering 3.0 (NEM 3.0)
California's current net metering program affects new installations:
Key changes:
- Export rates are lower than retail rates (approximately 75% of retail)
- Time-of-use rates apply to grid exports
- Battery storage becomes more valuable for maximizing self-consumption
Impact on solar economics:
- Still highly economical due to high electricity rates
- Battery storage provides additional value
- Self-consumption optimization becomes more important
Planning your California solar system
System sizing considerations
- Energy usage: Review your last 12 months of electricity bills
- Roof space: California homes typically have good roof orientation
- Future needs: Consider electric vehicles, heat pumps, or home additions
- Local regulations: Check with your city for any specific requirements
Optimization strategies
- Panel orientation: South-facing roofs provide optimal production
- Shading analysis: Ensure minimal shading during peak sun hours
- Efficiency vs. cost: Balance panel efficiency with overall system cost
- Battery integration: Consider storage for backup power and rate arbitrage
