Established in 2015 and with more than 7,000 unique solar installation projects under its belt, Sunlux was founded with the idea of making solar energy as simple and accessible as traditional electricity. The company has installed more than 14,000 kilowatts of solar energy across Southern California and Central Texas, and was named one of Solar Power World magazine’s “Top 500 Solar Contractors” in 2017, 2019, and 2020.

Top-Level Panels, Inverters, and More

Sunlux offers homeowners a selection of top-level solar panel, solar inverter, and roofing solutions. Sunlux trusts solar panels from LG, Panasonic, and Q CELLS, all of which average at least 19 percent energy efficiency and come with an equipment warranty of 25 years. As for solar inverters, Sunlux only trusts the best manufacturers: SolarEdge, Enphase, and SMA. These solar inverters track and monitor the performance of individual solar panels to ensure the roof-mounted solar PV system is running at peak efficiency.

In addition to all the essential components for a solar panel system, Sunlux also offers solar energy storage solutions (LG Chem and Tesla Powerwall) and EV charging stations to help homeowners take full advantage of solar power and save money on their monthly utility bill. 

Competitive Warranties

To supplement the 25-year equipment warranties from the manufacturers, Sunlux supplies customers with its own 25-year workmanship or service warranty, which covers the costs of parts and labor for system repairs.

The solar installer also guarantees its systems will perform at maximum efficiency for their projected 25-year lifespan. In short, the company provides lifetime support of every solar energy system it installs.

Full-Service Installation

Sunlux is present at every step of the installation process and does not employ third-party contractors for installation or design. During the free consultation and initial site survey, Sunlux's energy consultants will determine the household's energy needs, consumption, and potential electric bill savings.

The Sunlux team will then design and implement a custom solar energy system, pulling all the necessary permits prior to installation. Once the system has been inspected and improved by the city, it is cleared for interconnection.

Multiple Financing Options

Sunlux offers customers a number of ways to pay for solar energy. Not only can customers purchase their system outright or finance through a zero-money down, low interest solar loan, but they can also lease their solar panels or opt for a prepaid plan/power purchase agreement.

Each option has its advantages: out-of-pocket purchase and loans yield the greatest return on investment and qualifies homeowners for the Federal Solar Tax Credit. Solar leases and PPAs meanwhile, are cost-effective solutions that lock customers in to a low monthly rate (less expensive than their current electricity bill), sometimes with the option to purchase the system once the 20-year contract has expired.

Smart Home Integration

One exciting development in the solar industry is its integration with home automation components. Sunlux easily pairs with the Google Nest Smart Thermostat as well as the Leviton Load Center, a smart circuit breaker that helps monitor your home’s energy usage. 

Positive Review Portfolio

Sunlux reviews posted to Best Company are generally positive and exhibit relatively few customer complaints. Many satisfied Sunlux customers cited positive experience with customer service as well as the solar installation process at-large. On the occasion that a customer complaint arises, Sunlux is quick to respond and provide immediate support or solutions to the customer's problem.


The Bad

  • Limited Availability
  • No NABCEP Certification

Limited Availability

Sunlux is only available to residents of Southern California and Central Texas, both of which are highly competitive solar markets occupied by hundreds of solar installers. Verified Sunlux Reviews can help distinguish the company from the competition and give potential customers insight into the quality of its customer service and solar installation process.

No NABCEP Certification

Sunlux does not appear to have a certification from the North American Board of Certified Energy Practitioners (NABCEP), which would indicate that its technicians have undergone special, additional training. While the lack of a certification does not in any way imply poor installation quality, it can sometimes make the difference for a customer comparing multiple solar companies.


The Bottom Line

Sunlux is quite transparent in the exact type of solar panel systems it installs, the warranties used to support those systems, and the options provided to finance them. The company has installed thousands of kilowatts of clean energy and is prepared to help customers at every step of the installation process and beyond. Customers in California and Texas are encouraged to obtain a free quote, and read Sunlux reviews to determine if the company is right for them.

John Bassir Beverly Hills, CA

One star is too many ..... They are absolutely unprofessional . They gave me a bid and a timeline and it took 4 month to find out through the city expediter that SunLux design is faulty and it does not meet city standard , where we had provided them the exact requirements. Now after wasting so much of our time , they demand extra $5000 money for redesigning which requires more panel or stronger panel .. I ended up shopping the same with LA Solar whom are very professional and fast and demanded sunlux to refund my deposit and they did not . We took them to small claim court and they lost and up to day they are not paying whats owed to me so I am taking further action. Do your selves a favor and stay away from these guys
