Alpine – A Solar Opportunity

Veteran Owned Semper Solaris Supports Our Military

According to the Alpine Historical Society, Alpine has had the reputation of “Best Climate in the USA, by Government Report” since World War I. This makes Alpine the ideal place for solar panels. With sunny skies so much of the year, and warm temperatures that rack up the air conditioning, Alpine residents have nothing to lose and much to gain with solar panel installation. Solar panels can reduce and even eliminate electric bills—many homeowners even get money back from the electric company each month because of how much energy they’re producing. For Alpine residents who use an air conditioner or heater, or who simply want to reduce their energy costs, solar energy can be a significant asset. Alpine has also been named as one of Sperling’s Best Places to live. Many residents choose to stay as long as they can, meaning that solar panels are excellent investments that continue to bring positive returns to households for decades.

Going Solar Now

California has long been encouraging residents to install solar panels, both to reduce the state’s energy usage and to help build its green reputation. The California Solar Initiative enables homeowners interested in installing solar panels to apply for rebates, making solar even more affordable.  Programs like the HERO Program can also help homeowners install solar without having huge upfront costs. Now is the time to find solar panels for the best price, with the most incentives, and start saving. Solar panels have hit a steady low in cost, and have become more efficient than they’ve ever been. Best of all, the sooner that solar panels are installed, the sooner that savings begin. Why continue to spend money on electric bills when you can start paying nothing?

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.

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.

Not only is the timing good for incentives and rebates, but we are in an age with high-quality, efficient solar panels. Technology has developed since the invention of solar panels, and now solar panels are more efficient than they’ve ever been. Semper Solaris only uses SunPower solar panels, designed in the USA, which have set world records in efficiency.  SunPower panels are also unique in their ability to protect against corrosion and overheating, thanks to a copper backing. This copper backing makes the panels more durable, meaning that there’s less likelihood of breakage or cracking in the panels. With SunPower panels, you have a 25-year warranty that ensures that your solar panels provide the most worth for your home without breaking, eroding, or experiencing significant drops in efficiency.
