San Diego – Solar Capital of the US

Veteran Owned Semper Solaris Supports Our Military

Semper Solaris is honored to be part of the movement to make San Diego 100% renewable by 2035. San Diego’s commitment to clean energy is setting a worldwide example. We believe that the best way to reach San Diego’s goal is to make solar energy personal, hassle free, and easy to understand. Solar energy will save you money on your energy bills and give you the freedom to control your own energy production. Wouldn’t you like to stop sending the electric company a check every month? Installing a solar energy system from Semper Solaris will set you free from the electric company. San Diego has been blessed with a perfect climate for solar – mild temperatures, clear skies and sunshine every day. There’s no better place to go solar than San Diego. Our city has twice been named the solar capital of the United States, with the highest number of PV systems in 2009 and 2012.

The Time to Go Solar is Now

Solar prices have fallen 80% in recent years. Meanwhile, utility bills have continued to rise. Install American Made solar energy panels on your home to invest in your financial stability. Solar energy usage continues to rise as the United States works to meet national clean energy standards set at the Paris Climate Talks. Semper Solaris wants to make solar power simple for you. It’s a math problem – going solar will save you money on your monthly bills.

Our Military Roots

Co Founder Kelly Shawhan and family

As a Captain in the US Marine Corps trust means everything. Trust, to be there for my Marines. Trust, to be the expert. Trust, to get the job done right. That same philosophy stayed with me for the past 20 years as a contractor and a solar specialist. Solar can be complicated, but at Semper Solaris we pride ourselves on taking the time to help you understand how solar works and how to choose the right system. Find out why homeowners all over San Diego trust Semper Solaris.

Co Founder John Almond and Family

Solar power is all about the freedom to afford to run your AC. We make solar simple, stripped of hype, high pressure and high prices, the basic reality of solar electricity is simple. It’s a math problem, with an obvious answer. No land needs to be bought or leased, as it is already present. No additional infrastructure needs to be installed, as the home wiring is generally sufficient and the home is already tied into the grid. With current prices as low as they are, there will likely never be a better time to go solar.

Go green with Escondido Solar to cut your costs big time

Solar in Escondido

Escondido lies in San Diego County, and is a valley among coastal mountains. Locals know that Escondido is an excellent place for San Diegans—or anyone, for that matter, to settle down and retire. There’s plenty to do in Escondido, including golfing at one of their several golf courses. Escondido is a quieter, more beautiful part of town away from the downtown bustle. Escondido isn’t just for retirees, it’s also a great place for kids, visitors, and outdoor enthusiasts, with its entertainment and several hikes. Whether you’re a family looking to take advantage of the sunshine, or a retiree that would like to cut out one more bill from your life, going solar in Escondido could be right for you.

Why Go Solar Today?

There has never been a better time to go solar. Solar prices are at an all-time steady low, and solar panels are more efficient than they’ve ever been. Currently there are several rebates and incentives offered by both federal and state governments to install solar. Rebates and incentives will eventually expire or can be changed by future administrations at any time. Now is the best time to go solar with constantly rising energy costs and all time low solar rates, you can’t afford to wait any longer. This year, energy rates changed again in Southern California—including the addition of an expensive “high usage fee.” The sooner that you go solar, the sooner you can reduce or even eliminate your electricity payments. Some homeowners even produce enough energy that the electricity company pays them for all the extra energy! Why keep paying money to the electric companies? Install solar today to take advantage of all the rebates, coupons, financing programs, and more so that you can stop paying an arm and a leg for your home’s electricity.
