As the current #1 ranked solar EPC in Colorado, Progreen Solar entered our evaluation process on the lower end of the top-ten candidates in their home state. However, what followed was one of the most compelling conversations our research team has had during this ranking cycle. When we reached out to the company, we were connected directly with the owner. The exchange that followed left a strong impression on our lead evaluating engineer, who holds deep specialization in solar energy systems. What stood out was not simply a command of installation practices or product specifications, but a genuine and thorough understanding of the broader solar industry, its environmental impact, and the global implications of widespread solar adoption. It was clear that this is a business led by someone who lives and breathes the work, not just from a commercial standpoint, but from a place of real conviction about where the energy landscape is headed. ProGreen Solar also benefits from a strategic partnership with a roofing company that brings over 15 years of hands-on experience. That kind of structural expertise is difficult to replicate and contributed meaningfully to their overall score, reinforcing confidence in the quality of their rooftop installations and respective warranties. The company employs NABCEP-certified professionals and holds tier-one manufacturer certifications for all of the top brands, including being a Tesla Certified Installer. They work with premium panel brands such as REC, Silfab, and Hyundai, paired with Enphase, SolarEdge, and Tesla inverter platforms. Their equipment selections reflect a thoughtful approach to matching system components with each customer's specific needs. Across residential, commercial, and what appears to be small utility-scale projects, ProGreen Solar demonstrates a level of versatility that is uncommon among installers of their size. Their ability to operate across all three sectors with apparent confidence and competency speaks to the depth of their team and the leadership behind it. As a locally owned and operated company based in Longmont, ProGreen Solar brings firsthand knowledge of Colorado's solar landscape, permitting requirements, and local building codes. With a composite score of 87.3 out of 100, ProGreen Solar stands as our top-ranked solar company in Colorado for 2026.

Smart Wave Solar

0BBB Complaints
7Years in Business
DenverLocation

Smart Wave Solar has built a focused, high-volume residential solar practice in the Denver metro area over the past seven years, and their trajectory suggests a company that is growing into its ambitions without overextending. Headquartered at 4201 Madison Street in Denver, Smart Wave installs REC, Qcells, and Panasonic panels paired with Enphase microinverters, a hardware combination that reflects a preference for premium components over budget alternatives. They also hold designation as a Tesla Premier Certified Installer, which means they are authorized to sell and install Tesla Powerwall 3 battery storage systems, a credential Tesla reserves for its highest-performing dealer partners. The numbers behind Smart Wave's customer satisfaction are hard to argue with. A 4.7-star Google rating across 554 reviews is one of the stronger profiles in the Colorado market, and it reflects a company that is doing enough volume to generate that kind of feedback while keeping quality high enough to maintain the rating. Their NABCEP certification and REC Certified Installer status add professional credibility, and they hold an A+ rating with the Better Business Bureau. All panels carry a 25-year performance warranty that guarantees production benchmarks over the system's lifetime. Our research team did flag a small number of negative reports in Smart Wave's review history, including one incident involving property damage during an installation and some communication gaps during the project management phase. These are the growing pains that often accompany rapid scaling in the solar industry, and they are worth noting because they represent the difference between a solid company and a great one. Smart Wave appears to be investing in process improvements to close those gaps, but prospective customers should ask pointed questions about project management protocols and insurance coverage during the sales process. Smart Wave offers cash purchase and loan financing, and their focus on the Denver market means they have developed strong relationships with local permitting offices and utility interconnection teams at Xcel Energy. That kind of local fluency can shave weeks off a project timeline compared to working with a national installer unfamiliar with Colorado's specific regulatory landscape. With a composite score of 69.2 out of 100, Smart Wave Solar holds the third-ranked position in Colorado for 2026.

*Companies displaying 15 or more years in business are typically established electrical, roofing, or general contracting firms that expanded into solar installation in more recent years. The years shown may reflect the age of the parent organization or a strategic partner, not necessarily the solar division itself. This distinction is worth considering when comparing to dedicated solar installers, as purpose-built solar companies may offer more specialized expertise despite a shorter operating history.
