Quick Answer
San Jose works well for solar despite NEM 3.0 thanks to sky-high PG&E rates ($0.35-0.45/kWh per EIA data). Battery storage is now essential—self-consumption saves $0.40+/kWh vs $0.06/kWh export credits. Expect $2.80-3.50/watt with 7-10 year paybacks. SGIP battery rebates help offset storage costs in Silicon Valley.
Solar in San Jose
San Jose, the heart of Silicon Valley, offers strong solar potential. With more sunshine than San Francisco and sky-high PG&E rates, solar makes financial sense for most South Bay homeowners.
From my experience:Silicon Valley engineers love to run the numbers, and the numbers still work for solar in San Jose—even under NEM 3.0. Yes, export credits are lower, but when you're paying $0.40+/kWh at peak times, self-consumption value is through the roof. A battery isn't optional here anymore; it's how you capture the real savings. And given how many tech workers have EVs, charging your car with solar during the day is essentially free fuel.
San Jose Solar Stats
San Jose averages 257 sunny days and 5.3 peak sun hours daily (Source: NOAA climate data, NREL solar maps). PG&E rates average $0.35-0.45/kWh (EIA data)—among the highest in the nation. Even under NEM 3.0, solar + battery can reduce bills by 70-90%.

San Jose Solar Costs
Average System Costs
| System Size | Solar Only | Solar + Battery |
|---|---|---|
| 6 kW | $16,800-21,000 | $28,000-35,000 |
| 8 kW | $22,400-28,000 | $34,000-42,000 |

Federal 25D residential credit ended Dec 31, 2025. PPA/Lease still benefits from 30% through 2027.
PG&E NEM 3.0
San Jose is in PG&E territory, meaning NEM 3.0 rules apply. Export credits are reduced, but high PG&E rates mean self-consumption still delivers substantial savings.
NEM 3.0 Key Points
- Export credits: ~$0.05-0.08/kWh (75% below retail)
- Self-consumption: Worth full $0.35-0.45/kWh
- Peak hours: 4-9 PM most expensive
- Battery value: Essential for maximizing savings
Battery Strategy
Under NEM 3.0, batteries are highly recommended in San Jose. Store daytime solar and use it during expensive 4-9 PM peak hours to maximize value. Self- consumption saves $0.40+/kWh vs export credit of $0.06/kWh. (Source: utility tariff filings and DSIRE Database)
Incentives
Available Programs
- CA property tax exemption: 100% of solar value excluded
- No state sales tax: On solar equipment
- SGIP battery rebate: $150-1,000/kWh for storage
- Low-income programs: DAC-SASH, SOMAH available
Local Considerations
San Jose Factors
- Permitting: San Jose has streamlined solar permits
- HOAs: CA law protects solar rights
- Roof types: Mix of Spanish tile and composite
- Tree shading: Check for redwood and oak shade
Production Estimates
- Annual production: 1,500-1,700 kWh per kW installed
- 8 kW system: ~12,000-13,600 kWh/year
- Payback: 7-10 years with battery
The Bottom Line
San Jose is solid for solar despite NEM 3.0. High PG&E rates mean substantial savings from self-consumption. Battery storage is key to maximizing value. Expect 7-10 year payback with solar + battery.
