  • Solar Financing Options
  • Additional Home Services 
  • Veteran-Owned Company
  • Semper Solaris Reviews

American-Made Solar Panels

Semper Solaris' use of American-made solar panels, specifically Silfab and Qcells brands, showcases the company’s dedication to supporting domestic manufacturing and promoting sustainable energy practices within the United States. By prioritizing American-made products, it contributes to the growth of the local economy while ensuring the use of high-quality solar panels known for their efficiency and durability.

Home Energy Storage

Semper Solaris installs Tesla Powerwall home energy storage units, which are highly regarded for their cutting-edge technology and ability to store excess solar energy. This feature allows homeowners to maximize their energy usage and minimize reliance on the grid, enhancing the overall efficiency and sustainability of their solar system.

Solar Financing Options

Semper Solaris offers a variety of solar financing options, including the following:

  • Power Purchase Agreements (PPAs) — A financing option through which you only pay for the power you use, not the high upfront costs of panels and equipment. Power is purchased at a fixed-rate.
  • Solar Energy Loans — Similar to a conventional bank loan in which you pay for your panels in monthly payments. Semper Solaris can help you find the best solar loan for your needs.
  • HERO Program — The Home Energy Renovation Opportunity (HERO) program is a funding program for homeowners seeking to make home upgrades. The program is made possible through partnerships between contractors and local governments.

Semper Solaris will help you determine which funding options will best fit your needs. It’s also worth noting that the company also offers solar lease options.

Additional Home Services

In addition to solar installations, Semper Solaris also provides roof replacement, heating, and air conditioning services. This comprehensive approach allows customers to address multiple home improvement needs simultaneously, saving time and effort. 

By offering a range of services, Semper Solaris positions itself as a one-stop solution for homeowners, simplifying the process of transitioning to solar energy and improving the overall energy efficiency of their homes.

Regarding roofing specifically, the company has partnered with Owens Corning and is one of the few Owens Corning Platinum Preferred Contractors nationwide for all roofing projects. So if a customer needs to have their roof replaced before the solar panel installation, Semper Solaris can take care of it all in-house, which is a benefit few solar energy installers can provide.

Veteran-Owned Company

Moreover, Semper Solaris proudly emphasizes its veteran-owned status, drawing inspiration from the Marine Corps motto, "Semper Fidelis," which means "always faithful." This military discipline and attention to detail are ideally reflected in the company’s projects, providing customers with peace of mind and confidence in the quality of their work.

The Bad

  • Limited Service Area
  • Need to Read Fine Print

Limited Service Area

Semper Solaris only services certain areas within Arizona, California, Florida, Illinois and Texas. It isn’t unusual for a solar company to service a small number of states or certain areas, but it is important to know whether or not a company’s solar services are available in your area or not. 

Semper Solaris’ service area includes the following cities/areas:

Arizona California Florida Illinois Texas
  • Phoenix
  • Bakersfield
  • El Cajon
  • Bay Area
  • Campbell
  • Concord
  • Fresno
  • Inland Empire
  • Palm Desert
  • Rancho Cordova
  • Redlands
  • Sacramento

Semper Solaris is headquartered in El Cajon, California. Thus, the company has more areas that it services within California.

Need to Read Fine Print

Semper Solaris promotes various discounts and offers, such as the current $500 promotional coupon, which can be applied toward solar installations. While promotions may be appealing, it's essential for customers to carefully review the terms and conditions to ensure they fully understand the eligibility criteria, limitations, and potential exclusions associated with these offers.

Additionally, while Semper Solaris offers a 50-year platinum protection limited warranty for its roofing installations, it's crucial for customers to thoroughly read and understand the fine print to determine the extent of coverage. Clarifying the warranty terms will help ensure that homeowners have a clear understanding of what is included and any potential limitations or exclusions that may exist.

The Bottom Line

Semper Solaris’ installation of Tesla Powerwall units, comprehensive range of services, veteran-owned status, and commitment to American-made solar panels demonstrate their dedication to quality and sustainability. It also sets itself apart from solar-only-companies by offering roofing services and covers its workmanship with a surprisingly-extensive roof warranty. 

However, the need for careful scrutiny of promotions and warranty terms should be considered. Conducting thorough research and seeking clarification on any uncertainties will help potential customers make an informed decision when choosing Semper Solaris as their solar provider.

The majority of Semper Solaris reviews on BestCompany.com are positive, with customers frequently highlighting the company’s commitment to quality equipment and customer service.
