Dear Mr. Almond, I just wanted to touch base with you and let you how pleased we have been with Semper Solaris’ professional service. Every question we had in regards to getting solar electricity was answered to our full satisfaction so that we understood everything. I was so pleased with the immense amount of time…

The sun. Even from 93 million miles away, it has enough power to support all life on earth. And if you’re lucky enough to live in California, you’re in the perfect climate to harness that power for use in your own home. With moderate temperatures year-round throughout most of the state, clear skies, and plenty of sunshine, solar power is an ideal renewable energy source for the nation’s most populous state.

Californians have taken that message to heart. Based on the number of solar power systems currently installed in California, the golden state is already the solar capital of the United States, and the trend isn’t likely to slow down anytime soon. With traditional energy costs constantly on the rise, and environmental concerns growing, it makes sense that saving money and reducing dependence on non-renewable and Earth-harmful sources of energy are powerful reasons so many Californians have chosen to install solar panels on their homes.

But don’t think you’re entirely on your own when it comes to going solar. In an effort to promote the use of clean, renewable energy sources, both the federal and state government, along with many cities, offer rebates, tax credits, and incentives to homeowners who choose solar power over traditional sources of energy. So whether you own a home or a business in California, there has never been a better time to join the solar revolution.

When you choose Semper Solaris for your solar power needs, you aren’t just choosing a business; you’re choosing a business that puts pride in service, customer satisfaction, skilled workmanship, and the highest-quality products at the top of our list of “must haves.” We’re a local business, and we love our state and our country. In fact, Semper Solaris is owned and operated by veterans of the U.S. Marines and other military divisions. Our very name comes from the Marine Corp motto, “Semper Fidelis,” which means “always faithful.” We take that idea seriously; it is our vow to remain faithful to the military values of loyalty, duty, respect, selfless service, honor, integrity, and personal courage. That’s why our company is one of the fastest growing operations in the state of California. We keep our promises to our customers, and it shows; nearly half of our customer base has come from referrals. Feel free to check out our rave reviews on Yelp and you’ll see why Semper Solaris has such a solid reputation.

But we don’t stop there. We also take pride in using the best solar panels on the market: SunPower panels. Designed in the United States, SunPower panels are highly efficient – in fact, they are the highest efficiency panels on the market today. Plus, they are sleek and attractive — no more ugly panels marring the good looks of your home.

Give us a call. Our highly trained technicians will assess your energy needs, develop the best plan for your solar energy system, handle all of the necessary permits, and then install your panels within a few short days. And it will all be done right the first time: guaranteed. That’s our passion and our promise.

There are a lot of solar panel companies out there, so why should you choose us? Well, to start with, there’s our insistence on the best solar panels and the best customer service in the business. But the benefits of harnessing sun power don’t stop there. We’re also determined to save you a bundle on your utility bills. Here are a few of the perks you’ll be able to take advantage of.

If you’re still not convinced, give us a call and we’ll be happy to set up a free consultation. One of our Semper Solaris experts will sit down with you and explain how the entire process works. You’ll be glad you made the call!
