Sunlux panels and equipment

Sunlux installations
Sunlux handles design, permitting and installation in-house (unlike some solar companies that only sell contracts and outsource the work). The first step in the process is to book a free consultation to determine if solar is right for you.
- Consultation: The installation process starts with a visit to the location, where specialists survey for challenges and measure the available space.
- Planning: Within the following week, Sunlux designers draft a plan that matches your desired aesthetic and efficiency.
- Permits: The company then applies for permits. Permit approval may take up to a month.
- Scheduling: Once the permits arrive, the company will schedule an appointment to install your new solar energy system.
- Inspection: After passing inspection and receiving utility approval, energy production can officially begin.
Sunlux costs
Solar panel costs vary depending on the size of your roof and whether you purchase, finance, lease or prepay for your solar panels. On the high end, one Sunlux customer, Aldo in Corona, told us he spent $80,000 on a system.
Statewide, typical solar panels cost in California range $12,224 to $24,449. But homeowners rarely have to pay that much upfront, thanks to affordable financing and leasing options.
It’s best to get a personalized quote for the most accurate cost estimate. Sunlux offers a solar calculator that can help you estimate the cost of your solar system and utility cost savings over time based on your average monthly utility bill.
Sunlux payment options
Sunlux offers several different options for its solar energy systems:
- Purchase: You can buy the system outright. If you decide to purchase, there is a $1,000 deposit upfront. The remaining balance is typically due when installation begins.
- Finance: Sunlux partners with a few loan companies to offer $0 short- and long-term payment options.
- Lease: With solar leases, you pay nothing upfront. Then you pay a fixed monthly rate over a 25-year agreement.
- Prepaid lease: This option lets you prepay a locked-in rate for the electricity your solar energy system should generate over the next 25 years.
Sunlux warranty
Sunlux offers 25-year coverage on equipment, with additional warranty options that can include performance guarantees.
Sunlux also provides access to 24/7 monitoring platforms to its customers. This will let you check on the performance of your solar system and notify reps of any issues with your system that may arise.
FAQ
What is Sunlux?
Sunlux is a solar energy company that designs and installs solar systems for homes and businesses. It operates primarily in Southern California and is a certified installer for brands like Tesla Powerwall. Because it manages projects directly, customers typically have one company responsible for the entire installation process.
How long do Sunlux installations take?
Installation typically takes one or two days, though permitting and preparation can take several weeks to a few months.
Where is Sunlux available?
Sunlux is available in Southern California.
When was Sunlux founded?
Sunlux was founded in 2015.
Is Sunlux legit?
We consider Sunlux a legitimate option based on strong feedback from verified customers and the range of financing options it offers.
Some customers report predictable monthly payments compared with fluctuating utility bills. Christian in Rancho Palos Verdes said his financing payment was about $150 per month for six years, after which he would own the system outright.
Other reviewers mention a detailed installation process. Daniel in Wildomar appreciated the thorough site assessment, saying his representative “showed me how extensive their installation process is to prevent roof leaks.” That kind of upfront evaluation can help protect your roof and avoid costly issues later.
However, not all experiences are seamless. Robina in Paramount said that while her salesperson was responsive, she felt some important details — including roof compatibility — were not clearly explained upfront. She also described communication during the process as confusing and said she was reconsidering moving forward.
As with any solar company, homeowners should review contract terms carefully, confirm roof requirements early and compare multiple quotes before signing.
