About Semper Solaris
A veteran-owned California contractor
Semper Solaris describes itself as a veteran-owned solar company. Its about page says it was founded in 2012 to help California homeowners escape rising costs from traditional energy companies. The company states co-founders Kelly Shawhan, a former United States Marine Corps Captain, and John Almond, a business leader with construction experience, brought military values of honesty, integrity and hard work into solar power.
The company says its name was inspired by the Marine Corps motto Semper Fidelis, meaning always faithful, and that it is committed to hiring armed forces members. Its site describes a Semper Cares initiative providing energy solutions to deserving veterans. On its homepage, the company calls itself one of California's most award-winning contractors, a company claim, and says it started in San Diego.
Solar, battery, roofing, HVAC and windows
Its homepage lists solar, battery storage, roofing, windows, and heating and air conditioning as one company's home upgrades. Its about page says it expanded after launching to add battery storage, roofing and HVAC to its original solar work.
Its Sacramento page says solar solutions are tailored to a home's layout, energy needs and budget, through design, permitting, installation and performance. The company states a battery stores reserve energy from a connected solar system for use after sundown, during demand peaks, or during an outage, and its Sacramento page names the Tesla Powerwall as an example.
- Solar: custom residential installation, as described by the company
- Battery storage: for use after sundown, at peaks or in outages, as the company states
- Roofing: installation and repair, including replacement combined with solar
- HVAC: energy-efficient heating and air products, installation, maintenance and repair
- Windows: listed among home services on its homepage
Service area and how work is described
The company is based in California with multiple locations there, including Sacramento, San Diego, Fresno and Bakersfield on its location pages, and it also serves other states through official state sites: Phoenix in Arizona, Tampa and Orlando in Florida, and Dallas-Fort Worth in Texas, each with a local office address. The Sacramento page offers solar panels and battery storage for homeowners, plus roofing and HVAC, with tailored work rather than a one-size-fits-all approach.
For combined projects, the company states a roof replacement and solar installation done together can align roof and panel lifespans. It states, as both a solar and roofing contractor, it can remove and reinstall most existing systems for a new roof without another contractor. Its solar page says it tries phone troubleshooting first, then a technician next day or sometimes same day.
Warranty as the company states it
The warranty highlighted most prominently is a roofing warranty, not a solar warranty. Its homepage states that, as Owens Corning Platinum Preferred contractors, it can offer a 50 year warranty on Owens Corning roofs. Its solar and roofing page describes a 50-year workmanship warranty on Owens Corning projects and a lifetime warranty on Owens Corning materials.
That page also states the company has a 25-year warranty on the solar, in a question about combining roof and solar work. Keep the distinction the site makes: the 50-year figure applies to roofing with Owens Corning products, while the solar figure stated is different and shorter. Full terms are not set out in the pages reviewed.
