Cost Per Watt
- Stockton average: $2.60-3.00 per watt
- Budget installs: $2.30-2.60 per watt
- Premium installs: $3.00-3.50 per watt
Payback Period
- Typical payback: 8-11 years

- 25-year savings: $35,000-55,000+ depending on system size
PG&E NEM 3.0
As a PG&E customer, Stockton residents are under California's NEM 3.0 policy. Understanding these changes is crucial for maximizing solar value.
NEM 3.0 Key Points
- Export values reduced: ~75% lower than NEM 2.0
- Time-of-use critical: Export value varies significantly
- Self-consumption priority: Using power directly saves more
- Batteries valuable: Store daytime solar for evening use
NEM 3.0 Strategy
Under NEM 3.0, maximizing self-consumption is key. Battery storage lets you use cheap daytime solar during expensive evening peak hours instead of exporting for low credits. (Source: utility tariff filings and DSIRE Database)
PG&E Time-of-Use Rates
| Time Period | Typical Rate | Solar Strategy |
|---|---|---|
| Off-peak | $0.20-0.25/kWh | Solar produces during daylight |
| Peak (4pm-9pm) | $0.40-0.50/kWh | Battery discharge for savings |

Stockton Considerations
Central Valley Climate
- Hot summers: 100°F+ days reduce panel efficiency slightly
- Dust and smog: Occasional cleaning may be needed
- Mild winters: Good year-round production
- Tule fog: December-January may have foggy mornings
Stockton-Specific Factors
- Older homes: May need electrical upgrades
- Affordable housing: Lower entry costs than Bay Area
- Growing suburbs: Newer developments may have solar-ready homes
- Delta breeze: Evening cooling helps panel efficiency
Production Estimates
- Annual production: 1,500-1,700 kWh per kW installed
- 8 kW system: ~12,000-14,000 kWh/year
- Best months: May-September
- Winter production: 45-55% of peak (fog impact)
Summer Production
Stockton's hot, sunny summers mean peak solar production. An 8 kW system can produce 1,400+ kWh in July alone—more than enough to offset heavy AC usage. (Source: EPA Greenhouse Gas Calculator)
The Bottom Line
Stockton offers solid solar economics despite NEM 3.0. High PG&E rates and excellent Central Valley sunshine support 8-11 year payback periods. Battery storage helps maximize value under new net metering rules.
Key points:
- High PG&E rates ($0.28/kWh) make solar financially attractive
- Central Valley sunshine provides excellent production
- NEM 3.0 favors self-consumption and battery storage
- Hot summers create high AC bills that solar can offset
- 8-11 year typical payback with significant lifetime savings
