Sunlux specializes in residential panel installation and follows a stringent process to bring solar energy to its customers promptly. The five-step process includes:

Site evaluation

Sunlux will send a project manager to your home for a site evaluation, which will include roof measurements and a roof shading inspection and provide the design team with the necessary information for your system.

Design and engineering

A solar panel designer will create your custom solar package that’s specific to your home and energy needs.


Sunlux will compile the necessary paperwork and pull your municipality’s required permits.


Installation will begin as soon as the necessary permits are obtained. Construction will be completed by a certified Sunlux crew and you’ll have access to an onsite foreman if any issues or concerns arise.

Inspection and permission to operate (PTO)

After the installation, Sunlux will schedule an inspector from your municipality to examine the installation to ensure it’s up to code. Once the inspector approves the system, the company will submit a PTO package to your local utility provider to begin operation.

*Note: For customers who want to store their excess solar energy, Sunlux offers solar batteries from brands like Tesla, LG, and Enphase that can be installed during system installation.

How Much Does Sunlux Solar Panel Installation Cost?

Sunlux offers an online calculator that helps homeowners estimate their potential solar cost and savings. To give you an idea of your estimated savings with Sunlux, we received an estimate for a home in California with an average monthly utility bill of $110.

  2. Finance—The company gives customers the option of financing their solar system through a short- or long-term loan with as little as $0 down.
  3. Lease—Lease customers pay nothing for solar installation and are locked into a low monthly rate for 20 years.
  4. Prepaid—The prepaid payment option allows customers to enter into a power purchase agreement (PPA) with Sunlux where they pay a low, set rate for their electricity over 20 years. In a PPA, Sunlux owns and maintains the system.
