Los Angeles gets roughly 260-plus sunny days a year, but going solar here isn't as simple as picking the company with the loudest ad. Your utility, your roof, and your goals all change which installer actually makes sense.
A homeowner inside city limits served by LADWP is playing by a completely different rulebook than a homeowner in SCE territory under NEM 3.0 — different rates, different interconnection process, different math on whether a battery pays for itself. That's before you factor in equipment quality, financing structure, and who actually shows up if a panel underperforms in year twelve. Here's what to look for when evaluating solar energy companies in Los Angeles, and which names consistently come up for the right reasons.
Top Solar Energy Companies in Los Angeles
Sunrun
Lease & PPA Specialist · National ProviderSunrun is the largest residential solar lease and power-purchase-agreement provider in the country, making it a common starting point for LA homeowners who want to go solar with no money down. Service quality can vary by local crew, so it's worth checking reviews for the specific office handling your install.
LA Solar Group
Residential & Commercial Installer · Los Angeles-basedA locally based installer with over a decade in the LA market, LA Solar Group has completed thousands of residential and commercial projects and offers smart electric panels alongside standard system design, installation, and monitoring.
Ameco Solar
Solar & Roofing Bundles · Serving Greater LA Since 1974Ameco pairs solar installation with roofing work, which appeals to homeowners who need both done at once. Its long track record in Southern California and Tesla Powerwall certification make it a frequent pick for battery-inclusive systems.
OC Solar
In-House Crews & Battery Design · Licensed CA ContractorOC Solar runs its own installation crews rather than subcontracting, and has built a reputation for LADWP- and SCE-specific system design — a meaningful distinction for homeowners trying to model real savings under their actual utility's rules.
Tesla Energy
Vertically Integrated Panels & Powerwall · National ProviderTesla sells its own panels and Powerwall batteries as a single integrated system, with pricing that's often competitive on a per-watt basis. The tradeoff is a more standardized process with less room for custom design compared to smaller local installers.
Local & Boutique LA Installers
CaliEnergy, Solar Optimum, PacificSky & similar · Local providersBeyond the national names, Los Angeles has a deep bench of family-run and boutique installers offering more hands-on service for custom roof types, smaller jobs, or homeowners who want a single point of contact throughout the project.
What Different LA Homeowners Need
| Homeowner Profile | Priority Needs | Critical Issue |
|---|---|---|
| LADWP Territory (City of LA) | Installer fluent in LADWP's own net metering and interconnection process | LADWP sets its own rules independent of the CPUC — NEM 3.0 doesn't apply here |
| SCE Territory (Much of LA County) | Battery-inclusive system design built around NEM 3.0 export rates | Exporting excess power without storage now earns far less than it used to |
| Older Homes & Tile Roofs | Experience with retrofits, roof penetration methods, and mounting on tile or older shingle | A poor mounting job can void a roof warranty or cause leaks years later |
| Backup Power Priority | Battery storage sizing for essential circuits during outages | Not every battery install covers whole-home backup — confirm what's actually protected |
| Commercial & Multi-Unit Property | Larger system design, financing structures suited to businesses, permitting at scale | Underestimating usage growth leads to systems that are undersized within a few years |
Key Evaluation Criteria
Utility-specific expertise
Ask directly whether the installer regularly works with your utility — LADWP or SCE — and can explain how your bill savings will actually be calculated under its rules.
Licensing and in-house crews
Confirm a current CSLB license and ask whether installation is done by employees or subcontractors — accountability tends to be clearer with in-house teams.
Transparent, itemized pricing
Get at least three quotes broken down by equipment, labor, and permitting so you can compare like for like rather than a single bundled number.
Warranty coverage that's actually explained
Ask what's covered by the manufacturer versus the installer, and for how long — panel, inverter, and workmanship warranties often run on different timelines.
Post-installation support
Ask what happens after the system is activated — monitoring, maintenance, and who you call if production drops months or years later.
Pro tip: Ask a prospective installer to walk you through a recent project on your specific utility, roof type, and neighborhood, end to end — system sizing, permitting timeline, and what went wrong along the way. A vague pitch about "clean energy savings" tells you far less than one honest project story.
Red Flags to Avoid
High-pressure, same-day sales
Solar is a 25-year decision. A company pushing you to sign before you've compared quotes is optimizing for the sale, not your outcome.
Savings estimates that ignore your utility
If a proposal doesn't distinguish between LADWP and SCE rules, the projected savings on it aren't reliable.
Unlicensed or unverifiable contractors
Always verify a CSLB license number directly before signing — don't rely on a badge on a company's own website.
Vague warranty language
If a company can't clearly state what's covered, for how long, and by whom, get that in writing before you sign anything.
No plan for underperformance
Panels degrade and inverters fail. A company that can't explain what happens if production drops leaves you managing a system they installed.
The Bottom Line
Los Angeles's solar market ranges from national names like Sunrun and Tesla Energy down to locally rooted installers like LA Solar Group, Ameco Solar, and OC Solar. The right choice depends less on brand recognition and more on whether a provider actually understands your utility territory, your roof, and your usage.
A good solar partner should lower your bill, hold up through LA's heat and sun for decades, and still be reachable if something needs attention long after installation day. Choose accordingly.
