Semper Solaris is a veteran-owned solar installation and roofing company that services thousands of solar customers in Southern California and the surrounding territories.

Semper Solaris Construction, Inc. is a solar panel installation and repair and roofing company that operates exclusively in California. The privately-held company was founded in 2012 by co-owners Kelly Shawhan and John Almond. Shawhan is a former U.S. Marine Corp Captain with over 20 years of experience as a solar contractor, while Almond has more than two decades of experience in the construction industry.

The company's corporate headquarters are in El Cajon, in San Diego County. Semper Solaris has offices in eight California communities: San Diego, Santa Ana, Santa Fe Springs, Riverside, Hayward, Fresno, Bakersfield and Palm Desert.

In addition to their solar panel installation services, Semper Solaris handles solar maintenance, monitoring and repair assignments. Their licensed solar panel installation experts are available to help homeowners and business owners with all solar panel-related issues.

They will perform a full-site evaluation and can provide roofing repair and remodeling services for clients whose roofs are currently unsuitable

for solar panels. Semper Solaris is also a certified installer of the Tesla Powerwall home battery system.

Semper Solaris has established working relationships with some of the leading U.S.-based solar manufacturers, including Panasonic, LG Solar, Solaria, Sunrun, Silfab Solar, and Solar World. They specialize in the installation of American-made solar panels.

Financing for solar purchases is available through third-party sources, and Semper Solaris customer representatives can help connect clients with financial institutions that make solar loans. They can also introduce clients to the PACE loan program, which lets homeowners offset the cost of solar energy systems through property tax abatements. Power Purchase Agreements (PPAs) are also available through Sunrun (another company affiliated with Semper Solaris).

Since their launching seven years ago Semper Solaris has successfully completed several thousand solar installations in Southern California and beyond, and the company currently carries an A-plus rating from the Better Business Bureau.
