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.
-John Almond
Co-founder, Semper Solaris

Go green with Carlsbad Solar to cut your costs big time

Carlsbad – Perfect for Solar

 Carlsbad is one of California’s most pristine beach towns. It’s always a good day to camp at Carlsbad State Beach, or just to sit out and watch the waves. During spring, Carlsbad is also a great place to pick your own strawberries, or to visit the blooming flower fields. The same sunny climate that makes Carlsbad such a great place for beaches, strawberries, and flowers also makes it a great location for solar panel installation. This is especially true because SDG&E, the electricity provider for Carlsbad, gets 67% of its energy from natural gas. Natural gas is a limited resource, and also is just going up and up in price. There’s no sense in being at the mercy of the electric company any longer–install solar panels today to start saving.

 Why Go Solar Today?

 Now is the perfect time to go solar. Solar prices are lower than they’ve ever been, and have been at a steady low. The U.S. government, as well as the Californian government, has created several incentives and rebates to help more people find solar panel installation to be affordable—and with changing administrations, these could go away at any time. This includes a full 30% tax incentive, meaning that anyone who installs solar panels on their home can claim 30% of the full cost on their taxes. We also live in a time where electricity prices are just getting higher and higher as prices of natural resources like natural gas keep increasing. There always seem to be changing rates and new fees. There’s no reason to constantly be at the mercy of the electric company and pay more and more for the rest of your life when you can install solar today and start saving. The sooner that you install solar panels, the sooner you can reduce or even totally eliminate your electricity costs.

Why Choose Semper Solaris?

Here at Semper Solaris, we are the fastest-growing solar installation company in California, and for good reason. We are well known for having customer service as our priority, as our A+ Better Business Bureau  rating shows. Our strong customer service comes from our certified and trained team members, many of whom are our nation’s veterans. Our military values, such as personal responsibility, keeping your word, and faithfulness deeply influence everything we do. Semper Solaris was co-founded by John Almond and former U.S. Marine Captain Kelly Shawhan, and they ensured that their business was founded on strong values and extensive home improvement experience. Semper Solaris also only uses American Made solar panels, and we’ve built a national award-winning reputation in doing so. We give you the freedom to choose the best American solar panels because they are more durable than many other panels due to a special copper backing, and can also better withstand heat. Their solar cells have set world records in efficiency, meaning that you get more energy per panel than many others on the market. Because we are so confident in the quality of our Made in America solar panels, they all come with a bumper-to-bumper 25-year warranty. Call Semper Solaris today, and one of our experts will be happy to set up an appointment with you. Our team members come to your home and collaborate with you to discover a good fit for you, and also help you find financing options and rebates so that you can afford solar today.
