Last year’s “best solar companies in California” lists are graveyards. SunPower, gone in 2024. Sunnova and Mosaic, bankrupt in June 2025. Freedom Forever, the second largest residential installer in the country, filed Chapter 11 on April 15, 2026 and told the Delaware court on July 31 that it intends to convert to Chapter 7 liquidation. Roughly 190,000 households are now holding workmanship warranties from a company that will not exist.
That is the first thing I would tell anyone shopping for solar in California right now. The question is no longer just who installs well. It is who will still answer the phone in year eight when your inverter throws a fault code. This year we rebuilt our rankings around that reality: every company on this list holds an active California contractor license you can verify yourself at the Contractors State License Board, and financial staying power now weighs as much as price.
One more thing before the list. The 30% federal tax credit for purchased systems expired December 31, 2025. Any installer whose 2026 quote still shows it is either careless or dishonest, and either one should disqualify them. That single check will filter your shortlist faster than any review score.
Quick answer: The best solar companies in California in 2026 are NRG Clean Power, Ameco Solar and Baker Electric Home Energy among full-service California installers. Cash systems run roughly $2.50 to $3.50 per watt installed. There is no federal tax credit on purchased systems in 2026, so verify every quote against that fact and check every license at cslb.ca.gov before signing.
Key takeaways
- Five major solar companies serving California have gone bankrupt since 2024, including Freedom Forever, the state’s highest-volume installer. Longevity is now the top selection criterion.
- Every installer here carries an active CSLB license, listed in the table below so you can verify it in two minutes.
- California cash pricing runs about $2.50 to $3.50 per watt in 2026. A 7 kW system lands between $17,500 and $24,500 with no federal credit to subtract.
- Under NEM 3.0, an installer that cannot design and service battery storage is not a serious option. Every ranked company installs storage.
- Leases and PPAs are the only path to federal incentive value in 2026, which is why national lease providers are pitching harder than ever. Read the escalator clause.

How we ranked these companies
Six factors, weighted in this order for 2026: financial stability and years in business, because installer bankruptcies are now the biggest risk a California solar buyer faces. CSLB license standing and complaint history. Battery storage capability, since NEM 3.0 makes storage central to the economics. Verified review footprint across Google, SolarReviews, BBB, and EnergySage. Price positioning against the $2.50 to $3.50 per watt market range. And post-install service: whether the company runs its own service department or disappears after permission to operate.
We only rank companies with active California licenses. We removed two companies that appeared on last year’s list. Freedom Forever was cut after its April bankruptcy filing, and SunPower was cut because the original company was liquidated in 2024; the brand name now trades under new ownership and is not the installer Californians knew.
1. NRG Clean Power: best overall
Yes, this is our site, so weigh this entry however you like. Here is the factual case. NRG Clean Power has been operating in California since 1988, holds CSLB license #1026168, and installs solar, batteries, roofing, and EV charging with in-house crews from San Diego to Sacramento. We are a Tesla Certified Installer, an EnergySage Elite installer, a CNN Underscored Editors’ Pick, and a CALSSA member, with a 4.5-star Google rating across 225+ reviews.
Two things genuinely separate us in 2026. First, the best price guarantee: bring a competing itemized quote for the same equipment and we beat it, which matters in a market where identical hardware can be quoted $8,000 apart. Second, the sales model. No door knocking and no dealer network. You get a virtual consultation and an instant online quote, and the person who designs your system works for the company that installs it. The dealer model, where a sales organization subcontracts your install, is exactly the structure that collapsed at Freedom Forever and Sunnova.
Honest caveat: we are not always the cheapest bid you will get. Fly-by-night pricing exists in every California metro. Our position is that the gap buys you a company with 38 years of installs still standing behind them.
2. Ameco Solar: LA’s oldest solar name
Ameco’s lineage runs to 1974, making it one of the oldest solar names in America, now operating as Ameco Solar LLC (CSLB #1053172) out of Valley Village. Five decades of California installs is a survivorship signal almost nothing else in this market can match, and in a year defined by installer bankruptcies that history carries real weight. Ameco pairs solar with expert roofing across greater LA and Orange County, holds a 4.7-star SolarReviews rating, and is Tesla Powerwall certified.
The caveat is recent consistency. BBB reviews from the past two years include complaints about project delays and communication gaps after signing. The engineering reputation is earned; the project management currently gets mixed marks. If you go with Ameco, negotiate milestone dates into the contract.
3. Baker Electric Home Energy: the longevity pick
Founded in 1938 and family-run in Escondido, Baker (CSLB #858088) has been wiring San Diego County homes for 88 years and installing solar for over two decades. It won the BBB Torch Award for Ethics, runs its own electrical and HVAC divisions, and consistently ranks among SGIP’s most active residential storage developers, which shows in the state program data at selfgenca.com.
If your single biggest fear is your installer disappearing, Baker is the safest bet in Southern California. The tradeoff is price: Baker quotes typically land in the upper third of the market, and its service area is effectively San Diego County plus edges of Orange County and Riverside. Homeowners north of that need someone else.
4. Semper Solaris: roof and solar in one contract
Veteran-owned Semper Solaris (CSLB #978152) built its business on the insight that a large share of California roofs need work before panels go on. It is an Owens Corning Platinum Preferred roofing contractor, which lets it warranty a new roof for up to 50 years and sequence the re-roof and the array under one contract. That eliminates the worst sequencing mistake in solar: paying to remove and reinstall panels five years in when the roof underneath fails.
Semper was also the top developer by allocation in the most recent small residential storage step of SGIP, per the program’s own developer cap data, so its battery volume is real. The knocks: it is a high-volume operation, and review patterns show service response can slow in peak season. Get committed timelines in writing.
5. Solar Optimum: the warranty structure
Glendale-based Solar Optimum (CSLB #972228) has installed since 2008 and won Panasonic’s National Installer of the Year four times. Its differentiator is the cleanest warranty structure in the state: 25 years across panels, inverters, racking, workmanship, and performance. One term, one company to call, instead of five documents with five different expiration dates. It is also a Tesla Powerwall Premier installer.
Pricing sits at the premium end, and its footprint is Southern California plus the Bay Area rather than truly statewide. For buyers who rank warranty simplicity above all else, this is the pick.
6. Renova Energy: the desert specialist
Palm Desert’s Renova Energy (CSLB #910836, founded 2006) is the dominant installer in the Coachella Valley, with over 12,000 systems and the nation’s first NABCEP company accreditation. Desert installs are their own discipline: 120-degree attic temperatures derate equipment, and tile roofs crack under careless crews. Renova’s in-house RenovaPLUS service division maintains any brand of system, and its drone-based panel cleaning avoids putting boots on fragile tile.
Worth knowing: Renova was a SunPower Elite Dealer and took a hit when SunPower collapsed in 2024, pausing operations briefly before restructuring around its Mycrogrid solar-plus-battery brand. It came through, but ask any Coachella Valley installer, Renova included, how they handle orphaned SunPower equipment. If you live outside the desert, Renova is not your installer; inside it, they are hard to beat.
7. Sunrun: the lease giant
Sunrun (CA license #750184) is the largest residential solar company in the country and, after the 2026 shakeout, the last national heavyweight standing. Its relevance this year is structural: because the Section 48E commercial credit survived while the homeowner credit died, a Sunrun lease or PPA is one of the few ways federal incentive value still reaches a California roof. Sunrun’s CalReady program is also the largest residential virtual power plant in the nation, paying enrolled battery customers seasonal rewards.
The tradeoffs are the standard third-party-ownership ones. You do not own the system, escalator clauses can raise payments annually, and transferring the agreement complicates a home sale. Service quality varies by region because install crews differ by branch. Compare the 25-year total cost of the lease against a cash or loan purchase from a local installer before deciding, and read our California solar financing guide for the full lease-versus-buy math.
8. Tesla Energy: cheapest hardware, thinnest service
Tesla (CA license #255021) consistently publishes the lowest per-watt pricing in California, and if you want a Powerwall 3 ecosystem with Tesla’s app, ordering direct is the budget path. The company also runs paid virtual power plant programs with PG&E and SCE.
What you give up is white-glove anything. Site surveys are largely remote, timelines can stretch, and post-install service is ticket-based rather than a local crew you can call. Many buyers get a better outcome having a Tesla Certified Installer, several of which are on this list, install the same equipment with real project management attached.
9. LA Solar Group: the Valley value play
Van Nuys-based LA Solar Group has installed across LA since 2011 and appears among the most active developers in SGIP’s residential storage program data. Pricing is consistently below the LA average, and it self-performs solar, storage, and EV charger work.
Review scores are the concern: its SolarReviews average sits near 3 stars, with service responsiveness the recurring theme. It earns a spot on price and volume, not on service reputation. Verify its current license status and complaint disclosure at CSLB before signing, and get the workmanship warranty terms in writing.
10. SunLux: concierge project management
Corona-based SunLux built a strong reputation on communication: dedicated project managers, transparent timelines, and clean Tesla Powerwall installs across Orange County, Corona, and LA. Its SolarReviews rating runs around 4.7 stars, among the best of any mid-size California installer.
You pay for the experience; quotes typically land at $3.00 per watt and up. And as a 2015-founded company, it has not yet been through a full equipment lifecycle the way Baker or Ameco have. For buyers who value being informed at every step over squeezing the last $1,500 out of the price, SunLux delivers.
What solar actually costs in California in 2026
California cash pricing runs $2.50 to $3.50 per watt installed in 2026. Here is what that means in whole-system terms, with no federal credit, because there is none for purchased systems this year.
Table 2: Real California solar prices, August 2026 (cash purchase)
| System size | Solar only | Solar + one 13.5 kWh battery | Typical home profile |
|---|---|---|---|
| 6 kW | $15,000 to $21,000 | $28,000 to $37,500 | Condo or small home, $150 to $200 bills |
| 8 kW | $20,000 to $28,000 | $33,000 to $44,500 | Typical 3-bedroom, $250 to $350 bills |
| 10 kW | $25,000 to $35,000 | $38,000 to $51,500 | Larger home with AC or EV, $400+ bills |
Battery pricing reflects a single Tesla Powerwall 3 or FranklinWH aPower 2 installed at 2026 California rates. See our full solar battery cost breakdown for per-model numbers. No federal tax credit is included because Section 25D expired December 31, 2025; leases and PPAs can still carry Section 48E value through the third-party owner.
Three pricing notes worth more than the table. First, identical equipment gets quoted at wildly different prices in this state; three quotes is the minimum, five is better. Second, the battery is not optional math under NEM 3.0. Exports pay 5 to 8 cents while evening imports cost 40 to 80 cents depending on your utility, so a solar-only system leaves most of the value on the table for PG&E, SCE, and SDG&E customers. Third, if you are on LADWP or SMUD, you are still on near-retail net metering and solar-only still pencils; do not let a SoCal sales script sell you urgency that does not apply to your utility.
How to choose a solar company in California in 2026
Run every finalist through five checks, in this order.
Check the license first. Search the company at cslb.ca.gov. You want an active C-46 or C-10 classification, the exact business name that appears on your contract, and a clean complaint disclosure. Freedom Forever was placed on CSLB probation in October 2024, eighteen months before its bankruptcy. The warning was public the whole time.
Ask who actually installs. “Do you self-perform with W-2 crews, or do you sell and subcontract?” The dealer model concentrates risk: when the sales entity fails, your warranty and your half-finished project fail with it.
Test the quote for dead incentives. If the proposal subtracts a 30% federal credit on a cash or loan purchase, walk. If it promises an SGIP rebate as a sure thing, be skeptical; every residential SGIP budget is currently closed or waitlisted, so a rebate is upside, not a line item.
Interrogate the warranty. Who holds the workmanship warranty, the installer or a third-party insurer? A 25-year promise from a 3-year-old company is worth less than a 10-year promise from a 40-year-old one, unless it is backed by an insurance product that survives the installer.
Match the design to NEM 3.0. The right 2026 design maximizes self-consumption: battery sized to your 4 to 9 p.m. load, panels oriented for your usage pattern rather than maximum midday export. An installer who quotes solar-only to a PG&E customer without discussing storage has not kept up. Our guide to how much solar panels cost in California walks the full NEM 3.0 design logic.
Frequently asked questions
Who is the best solar company in California? NRG Clean Power is our top overall pick for 2026, on the combination of a 38-year operating history, statewide in-house crews, a best price guarantee, and full solar, battery, roofing, and EV scope. For San Diego County specifically, Baker Electric Home Energy’s 88-year history makes it the strongest longevity pick. The honest answer is that the best company depends on your county, your roof, and whether you are buying or leasing.
How much does solar cost in California in 2026? About $2.50 to $3.50 per watt installed for a cash purchase. A typical 8 kW system runs $20,000 to $28,000, and adding one 13.5 kWh battery brings the project to roughly $33,000 to $44,500. There is no federal tax credit on purchased systems in 2026.
Is solar still worth it in California without the federal tax credit? For most homeowners on PG&E, SCE, or SDG&E, yes, because those utilities charge 34 to 46 cents per kWh, roughly double to triple the national average. Payback periods stretched by two to three years when the credit ended, so honest modeling matters more, and a battery is now central to the math under NEM 3.0.
What happened to Freedom Forever and SunPower? The original SunPower filed bankruptcy in 2024 and was liquidated; the brand was sold. Freedom Forever filed Chapter 11 on April 15, 2026 and moved to convert to Chapter 7 liquidation in July. If either installed your system, your equipment warranties still stand with the manufacturers, but installer workmanship warranties are at risk. Our Freedom Forever bankruptcy guide covers what affected homeowners should do.
Should I lease or buy solar in California in 2026? Buying still wins on 25-year total cost for most homeowners who can finance it, even without the federal credit. Leasing wins on year-one cash flow and is now the only route to federal incentive value, since the third-party owner claims Section 48E. Compare total lifetime cost, check the annual escalator, and understand the home-sale transfer terms before signing either.
How do I verify a solar company’s license in California? Go to cslb.ca.gov, use the Check A License tool, and search by the exact business name or license number. Confirm the license is active, carries a C-46 or C-10 classification, matches the name on your contract, and shows no disciplinary actions. It takes two minutes and would have flagged the industry’s biggest failure eighteen months early.
The bottom line
The 2026 California solar market rewards a different kind of buyer than 2023 did. Cheap money is gone, the federal credit for purchases is gone, and the growth-at-all-costs installers are gone with them. What is left is a market where electricity costs 33 cents a kilowatt-hour and rising, where a well-designed solar and battery system is still the best hedge a California homeowner can buy, and where the company you choose matters more than the panel brand ever did.
