Quick Answer
Los Angeles is one of America's best solar markets with 284 sunny days (NOAA data) and high LADWP rates of $0.22-0.28+/kWh. If you're served by LADWP (City of LA), you get true 1:1 net metering—one of the best utility policies in California. Expect $2.80-3.40/watt and 5-7 year paybacks. SCE customers outside city limits face NEM 3.0's reduced export rates.
Solar in LA
Los Angeles offers an exceptional combination for solar: abundant sunshine, high electricity rates, and supportive utility programs through LADWP (Los Angeles Department of Water and Power). According to NOAA climate data, LA averages 284 sunny days annually.
From my experience:Here's the thing about LA—your utility matters more than your address. If you're in actual City of Los Angeles and served by LADWP, you've got one of the best solar situations in California with real 1:1 net metering. But step outside city limits into SCE territory and you're dealing with NEM 3.0's reduced export rates. First question before anything else: check your electric bill and see who's charging you.

LA Solar Costs
Average System Costs
| System Size | Gross Cost | After Incentives* |
|---|---|---|
| 5 kW | $14,000-17,500 | $14,000-17,500 |
| 7 kW | $19,600-24,500 | $19,600-24,500 |
| 10 kW | $28,000-35,000 | $28,000-35,000 |
*Federal 25D residential tax credit ended Dec 31, 2025. PPA/Lease options still benefit from 30% credit through 2027.
Cost Per Watt
- LA average: $2.80-3.50 per watt
- Budget installs: $2.50-2.80 per watt
- Premium installs: $3.50-4.50 per watt
LADWP Net Metering
Los Angeles residents served by LADWP have a significant advantage over those served by SCE (Southern California Edison). LADWP still offers traditional net metering.
LADWP Solar Programs
- Net Energy Metering: 1:1 credit for excess generation
- True-up annually: Credits carry forward throughout year
- No time-of-use required: Flat rate option available
- No interconnection fee: For systems under 30 kW
LADWP vs SCE
LADWP customers get traditional net metering with 1:1 credits. SCE customers are on NEM 3.0 with reduced export rates. This makes solar significantly more valuable for LADWP customers. (Source: utility tariff filings and DSIRE Database)

LA-Specific Considerations
Factors for LA Homeowners
- Roof type: Many Spanish tile roofs - slightly higher install cost
- Flat roofs: Common in LA, require tilt mounts or ballasted systems
- Air quality days: Smog can slightly reduce production
- Wildfire zones: May affect insurance, but solar helps resilience

LA Solar Production
- Annual production: ~1,600-1,800 kWh per kW installed
- 7 kW system: ~11,000-12,500 kWh/year
- Best months: May-September
- Winter production: ~60-70% of summer
Production Estimate
A typical 7 kW system in Los Angeles produces 11,000-12,500 kWh annually, enough to offset most households' electricity usage completely. (Source: EPA Greenhouse Gas Calculator)
The Bottom Line
Los Angeles is excellent for solar. High sunshine, high electric rates, and LADWP's favorable net metering make solar a smart financial decision for most LA homeowners.
Key points:
- LADWP customers have better net metering than SCE customers
- Expect 5-7 year payback for purchased systems
- California offers property tax and sales tax exemptions
- Consider PPA/Lease to benefit from remaining federal incentives
