The 5 Best Solar Companies in Los Angeles, CA (2026 Ranked)

Los Angeles has no shortage of solar companies. Type "solar installer near me" into Google and you'll get 40 results before you finish the sentence. The problem isn't finding someone — it's figuring out who's actually worth calling.

We've been installing solar across LA County for years. We pull our own permits, we know which LADWP inspectors to expect, and we've seen what happens when homeowners go with the wrong company. So we put together this list — not as a puff piece, but as an honest ranking.

A few things upfront: we're #1 on this list. We're going to be transparent about that. But the other four companies on this list are genuinely good at what they do, and we'll tell you exactly what they're better at than us.

How We Ranked These 5 Solar Companies

Not all "Best Solar Companies in Los Angeles" lists are created equal. A lot of them rank whoever paid to be listed. We didn't do that.

We judged each company on five criteria: pricing and financing options, installation timeline from contract to system installation, local permit experience (LADWP's interconnection process is different from SCE's and trips up a lot of national installers), equipment quality, and post-install support. Here's what we found.

#1 — Green Conception: Best Overall Solar Installer in LA

  Best for: Homeowners who want the lowest net price, fastest timeline, and a local team that answers the phone.  

We'll be straight with you. We're ranking ourselves first because the numbers back it up — not because we wrote this article.

Here's what sets us apart. We're a licensed solar AND roofing contractor (CSLB #964965). That matters more than most people realize. If your roof needs work before the panels go on — and in LA, plenty of roofs do — you don't have to coordinate two separate companies. We handle both. Our roof replacement with solar panels in Los Angeles service lets you bundle everything into one project, one contractor, one timeline. That alone saves most homeowners two to four weeks.

On price: we keep our overhead low through AI-driven operations, and we pass those savings directly to you. Most national installers carry heavy sales teams and franchise costs — we don't. That's how we consistently come in below what Sunrun and Tesla quote for the same equipment.

Our install timeline in LA County runs 6 to 10 weeks from signed contract to installation. That's faster than Sunrun and Tesla by most accounts we've seen. We use Enphase IQ8X microinverters on the majority of our builds — they cost more than string inverters, and we use them anyway, because if one panel underperforms due to shading from a neighbor's tree, the rest of the array keeps running at full capacity. You can also pair your system with a Tesla Powerwall installation in Los Angeles for whole-home backup during LADWP outages.

We also install Level 2 EV chargers in Los Angeles — so if you're buying an EV or already have one, you can bundle charger installation with your solar project and power it for essentially nothing.

One thing we're honest about: we're not the right fit if you want a lease — meaning you want someone else to own the panels and you just pay a monthly rate. We do loans (including zero-upfront options) and cash purchases. If a solar lease specifically is your priority, Sunrun is a better call.

#2 — Sunrun: Best for Solar Lease / No Ownership Required

  Best for: Homeowners who specifically want a lease — lower bills without owning the system.  

Sunrun is the largest residential solar company in the country. They didn't get there by being terrible. Their lease and PPA products are genuinely useful for homeowners who want lower bills and have no interest in owning or maintaining the equipment themselves.

The trade-off is ownership. With a Sunrun lease, you don't own the panels — Sunrun does. That affects your home sale and your options if Sunrun's pricing or service changes over a 20 to 25-year contract. It's a real consideration worth thinking through before you sign.

Worth noting: if zero upfront cost is the appeal but you'd prefer to actually own your system, a solar loan gets you there without the lease trade-offs. We offer zero-upfront loan options as well. Their install timelines tend to run 10 to 16 weeks in LA. If you're specifically comparing a Sunrun lease to a loan purchase, run the 10 and 20-year math before you decide.

#3 — Tesla Energy: Best Brand Recognition

  Best for: Homeowners who want the Tesla Powerwall ecosystem and trust the brand name.  

Tesla makes good equipment. The Powerwall 3 is one of the best home batteries available right now, and their TSP-420 solar panels are solid performers. The brand recognition also helps at resale — "Tesla solar" is something buyers understand without explanation.

Here's the thing: you don't have to buy from Tesla to get Tesla equipment. We're an authorized Tesla Powerwall installer. You can get a Powerwall 3 through Green Conception at a lower installed price than Tesla's own sales process, with the same hardware and typically a faster timeline.

Tesla's direct sales model has improved since the early days, but their post-install customer service reputation is still mixed. If something goes wrong, you're dealing with a large national organization. With us, you're calling the person who installed it.

#4 — SunPower / Maxeon: Best Premium Panels

  Best for: Homeowners with limited roof space who need maximum output per square foot.  

SunPower's Maxeon panels are the most efficient residential panels on the market. If your roof is small or heavily shaded and you need to squeeze maximum output from every available square foot, they're worth the conversation.

Worth knowing: SunPower filed for bankruptcy in 2024 and has gone through restructuring. The Maxeon panel business continues, but warranty support and long-term service are legitimate questions to ask before you sign anything. Get clear answers on who's backing the warranty and what happens to your service agreement if the company changes hands again.

For most LA homeowners with a standard-sized roof, the premium over a high-quality standard panel is hard to justify on the numbers alone. But if roof space is genuinely constrained, they're at the top of the list.

#5 — Palmetto: Best Monitoring and App Experience

  Best for: Tech-forward homeowners who want detailed real-time data on their system.  

Palmetto's platform is genuinely impressive. Their app gives homeowners real-time production data, savings tracking, and proactive performance alerts — better than most competitors in terms of the software experience.

They've also built a "Palmetto Protect" monitoring subscription, which is an interesting model. Some homeowners appreciate knowing someone's actively watching their system; others see it as an ongoing cost that good equipment shouldn't require.

Their installer network is third-party, so quality can vary more than with a company using its own crew. Ask specifically who's doing the install in your area before you sign. The software is great — just make sure the installation team is too.

How to Choose the Right Solar Company in Los Angeles

Check the CSLB license first

Every solar installer in California needs a contractor's license. You can verify any company at cslb.ca.gov in about 30 seconds. Don't skip this. An unlicensed installer can't pull permits legally, and if something goes wrong, your homeowner's insurance may not cover it. Our license is CSLB #964965 — look it up.

Ask specifically about the LADWP experience

LADWP's interconnection process is different from SCE's, and installers who work mostly in SCE territory sometimes underestimate the LADWP timeline. Your activation can get delayed by months. Ask how many LADWP interconnection applications they've submitted in the last 12 months and what their average timeline to system installation is.

Get three quotes, but compare the right things

A 10kW system in LA County should land somewhere between $28,000 and $38,000. If someone's quoting you $52,000, you deserve a detailed explanation. Compare the actual installed system price — equipment, labor, permits, everything in. Ask about the inverter type: Enphase IQ8X microinverters versus string inverters is a real difference in performance and warranty coverage.

Frequently Asked Questions

How long does solar installation take in Los Angeles?

It depends on your utility. LADWP interconnection runs 8 to 14 weeks on average because of its separate approval process. For the install itself — panels on the roof, system running — we typically get that done 6 to 10 weeks from the signed contract. SCE permitting is faster overall, usually 6 to 10 weeks from contract to fully installed.

Does Green Conception serve all of Los Angeles?

Yes. We serve the LA city and county, including the San Fernando Valley, West LA, South LA, the Eastside, and surrounding cities. We pull permits across multiple LA County jurisdictions and have ongoing relationships with local inspectors.

What's the cheapest way to go solar in Los Angeles in 2026?

Cash purchase gives you the best long-term return because you pay nothing in interest and own the system outright from day one. If you don't want to pay cash, a solar loan — including zero-upfront options — almost always beats a lease when you run the 10 and 20-year math. You own the system, you build equity, and you're not locked into someone else's pricing for 25 years.

Is Sunrun worth it in Los Angeles?

Their lease model works if you genuinely want someone else to own and maintain the system — zero ownership is the appeal. But over 20 years, homeowners who own their system almost always come out ahead financially. There's also the home sale complication — a leased system transfers with conditions, and not every buyer wants to take one on. Worth thinking through before you sign.

Are SunPower panels still a safe investment given the bankruptcy?

The Maxeon panel line continues. The efficiency numbers are real. But before you commit, ask specifically who's backing the 25-year warranty and what happens to your monitoring and service agreement if the company structure changes again. A good dealer will answer this clearly. If they get defensive, that tells you something.

Bottom Line

Choosing a solar company in Los Angeles comes down to four questions: Is the license current? Do they know LADWP's specific process? What's the real installed price — not a quote that hides costs until the contract? And who answers the phone when something goes wrong two years from now?

We're biased, obviously. But we're also the ones pulling LADWP permits, installing Tesla Powerwalls, and handling roofs that need work before the panels go on. We're CSLB licensed (#964965), we use Enphase IQ8X microinverters, and we keep our prices lower than the nationals by running lean — not by cutting corners on equipment.

If that sounds like what you need, get in touch. We'll give you a real quote — not a lead form that sells your number to six installers.
