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.

The Good

  • Top-Level Panels, Inverters, and More
  • Competitive Warranties
  • Full-Service Installation
  • Multiple Financing Options
  • Smart Home Integration
  • Positive Review Portfolio

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.

Felt that once sales associate finished sale he didn’t check back afterwards to answer any questions. There were multiple people involved and it was confusing in who was our go-to person at times. Erika continues to keep in touch which I appreciate. Disappointed the delay in the Tesla battery wasn’t brought to our attention immediately. They waited til contract was signed and then told us the details. We signed up fall 2020, installed winter 2020 and have been told Tesla won’t be sending out batteries until after summer when we need it most. No discounts for inconvenience was offered. Just tough luck.

We were looking to purchase and Sunlux had a good loan program. Other companies wanted to lease to us and we didn't really want to lease, we wanted to purchase. Once we got installation scheduled, it went very very smoothly, it was excellent. The sales team is excellent but you might have to press them on time. I had to be persistent to get my installation scheduled. Some people were very responsive and very helpful like Chris D.--he was excellent--and then there's some that were hard to get ahold of or get an answer from.

I chose Sunlux because it is a smaller company and I was looking for a more personalized service rather than being just one in a line of a million people. The installation process was a little slow. Our project manager was a little challenging and didn't provide a lot of direction or clarity and required me as a customer to do a lot of follow up and figure out what the next steps were.

The installation process was seamless. I think it would've been nice to have a follow-up call from the the representative--I was never walked through downloading the app or even how to use the app--so that would've been a nice addition that's all.

The quality of the product appears to be fine. The people are neat, polite and care about providing good customer service, however the communication needs improvement in order to receive 5 out of 5 stars.

The process went fairly well but with one issue that took a while to resolve but it was resolved to my satisfaction. The workers that I dealt with were positive and the sales representative also seemed knowledgeable.

Best pricing options and appeared to be most knowledgeable about the product. A little slow on the implementation and issues with local utility.

The sales person needs to explain everything. They need to check to see if there is a space for the box for the panels
