Best Solar Companies in Los Angeles, California (2026 Reviews)
9 installers compared. Licensed, bonded, and confirmed to serve Los Angeles. Honest notes on who each company actually fits, including the trade-offs sales reps skip over.
Los Angeles sits in LADWP territory, where residential electricity costs roughly 22.0¢/kWh — among the highest in the nation. That puts residential solar in a strong payback window for Los Angeles homeowners, but the right installer matters as much as the economics.

What's Different About Solar in Los Angeles
Los Angeles is the largest city in California with nearly 4 million residents, served by the Los Angeles Department of Water and Power (LADWP). While LADWP rates are lower than the major investor-owned utilities, the sheer size of the city combined with sprawling geography creates distinct neighborhoods with very different solar economics. Here's what Los Angeles homeowners need to know about their bills and solar options.
If your home is within 5-10 miles of the coast (Santa Monica, Malibu, Playa Vista, Westchester), expect 15-25% lower solar production June through August due to morning and midday fog. Check Google Project Sunroof for your specific address. Inland homes see consistently higher production.
Neighborhoods like Los Feliz, Silver Lake, and areas within Coastal Commission jurisdiction require architectural review. While the Solar Rights Act protects your right to install, design review boards may require specific mount styles or colors. Plan an extra 30 days for approvals.
Los Angeles-Specific Solar Considerations
Los Angeles averages approximately 3,284 hours of sunshine per year with 5.8 peak sun hours per day. The variability is significant: coastal neighborhoods near Santa Monica and Malibu see 20-25% less production due to marine layer fog (especially June-August), while inland areas like the San Fernando Valley and East LA receive excellent, consistent solar potential year-round. Most LA roofs face south or west, providing good orientation.
When solar may not be the right fit in Los Angeles: If your monthly bill is under $80 (rare in LA, but possible for very small apartments or south-facing rentals), the savings may not justify the complexity. Renters — a significant portion of LA population — cannot typically install owned solar without landlord permission. North-facing homes in deep canyons (Hollywood Hills, Griffith Park area) or heavily shaded by surrounding buildings may see production too low to justify installation. Coastal properties requiring Coastal Commission design approval may face long timelines.
What Actually Matters When Comparing Solar Companies in Los Angeles
- CSLB license and classification. Every installer must hold an active C-46 (Solar) or C-10 (Electrical) license. Verify at cslb.ca.gov before signing.
- Price per watt installed. In Los Angeles today, cash-purchase pricing typically lands $3.00–$4.50 per watt installed. PPA and lease pricing should equate to 60–75% of your LADWP bill in year one with a ≤2.9% annual escalator.
- Workmanship warranty length. 10 years is table-stakes. 25 years is the gold standard. Anything under 10 years should eliminate the installer from your shortlist.
- Panel and inverter brands. Tier-1 panels (Qcells, Silfab, REC, Canadian Solar, Maxeon) and name-brand inverters (Enphase, SolarEdge, Tesla) significantly out-perform house-brand private labels. Insist on specific brand and model before signing.
- In-house crew vs subcontracted. Some national brands subcontract installs to local crews. Quality varies by dealer. Ask directly: “Will your own W-2 employees do my install, or a subcontractor?”
- NEM 3.0 realism. Under NEM 3.0 (net billing), LADWP pays only ~retail rate credit for exports — about 75% less than pre-2023 rates. Payback math depends heavily on self-consumption and battery storage. A good installer explains this; a bad one hides it.

The Bottom Line for Los Angeles Homeowners
Los Angeles has excellent solar potential in most neighborhoods, with the major caveat being coastal fog and historic district restrictions. If you are inland or in newer neighborhoods, LADWP's tiered rate structure and LA's abundant sunshine make solar a solid investment. Check your specific address on Google Project Sunroof, understand your design review requirements if applicable, and explore LADWP's net-metering options.
