Sun Solar has been the leading dedicated solar installer in the Springfield area for 14 years, building a client base across southern Missouri and parts of northern Arkansas. In a region where solar is still gaining traction and homeowner education is a critical part of the sales process, Sun Solar has invested heavily in helping customers understand their options rather than simply pushing a sale.
What earned Sun Solar the top spot in Missouri was their combination of experience, volume, and regional expertise. Their 4.4-star rating from 548 reviews reflects the reality of high-volume operations in a market where customer expectations are still being formed. The company is transparent about production estimates and has built trust by delivering systems that meet or exceed their projections.
Sun Solar is NABCEP certified and handles residential and commercial installations throughout the Ozarks region. Their familiarity with Ameren and Empire District Electric interconnection procedures streamlines the process for homeowners.
The company has also been an active voice in the Missouri solar policy conversation, advocating for net metering protections and incentive programs that benefit residential customers.
With a composite score of 79.9, Sun Solar is our top-ranked solar company in Missouri for 2026.

The Solar Guys has built what is now the longest-standing dedicated residential solar practice in the Kansas City metro and Des Moines markets, and the company's most recent recognition pattern speaks louder than any self-reported metric. The Solar Guys received the EnergySage Installer of the Year 2026 award — a marketplace-level recognition that selects from EnergySage's nationwide network of vetted installer partners and ties directly to homeowner project-outcome data, customer satisfaction, responsiveness, and operational consistency. The company is also ranked among the top five solar installers in both Missouri and Kansas on the EnergySage Marketplace, and was voted the #1 Solar Company in Kansas City by The Pitch in 2024.
What stood out to our research team is the breadth and depth of the residential portfolio. The Solar Guys has installed ground-mount systems, roof-mount systems, and carport solar across homes and businesses throughout the Midwest, and the company's customer offerings range from straightforward residential solar panel installations to integrated battery storage systems. The Kansas City and Des Moines operating footprint gives the company three meaningful metropolitan markets — Kansas City Missouri, Kansas City Kansas, and Des Moines Iowa — across which to develop the kind of permitting fluency, utility interconnection experience, and crew specialization that translates to predictable project timelines for homeowners.
Prospective customers should ask pointed questions about which physical office and crew handles installations in their specific Missouri county, since the multi-metro footprint means routing logistics can vary. Reasonable diligence questions include verifying the specific NABCEP individual credentialed for the homeowner's system design, confirming Evergy or Ameren Missouri interconnection experience for the project's service territory, pinning down the workmanship warranty term and dispute-resolution path, and asking which panel and inverter manufacturers the company is currently authorized to install. The fundamentals — longest-standing solar company in Kansas City and Des Moines, EnergySage Installer of the Year 2026, EnergySage top-five rankings in both Missouri and Kansas, and a residential-and-commercial dedicated solar business model — make The Solar Guys our second-ranked Missouri pick for 2026.
With a composite score of 78.0 out of 100, The Solar Guys holds the second-ranked position in Missouri for 2026.
StraightUp Solar has spent nearly two decades building what is now one of the most credentialed dedicated residential solar practices headquartered in St. Louis. Founded in 2006 and based at 11696 Lilburn Park Road in St. Louis, the company has installed more than 3,000 residential and commercial solar projects across Illinois and Missouri, and the in-house roster is unusually NABCEP-dense — the company states that more than half of its team holds NABCEP individual certification, a credentialing concentration that is rare in the residential solar industry and that our research team treats as a meaningful professional-standard signal at this volume tier.
What stood out to our research team is the comprehensive single-source operating model. StraightUp Solar manages residential and commercial solar projects end-to-end — design, engineering, permitting, installation, and post-install maintenance — with dedicated electricians, NABCEP-certified technicians, and installers operating as full-time employees rather than subcontractors. The company is fully licensed and insured in both Missouri and Illinois, and the dual-state operating model translates into deep familiarity with Ameren Missouri, Ameren Illinois, and ComEd interconnection workflows. StraightUp also maintains an active EnergySage Marketplace profile and a published service offering that includes maintenance for systems originally installed by other companies.
Prospective customers should know that StraightUp's residential focus is paired with substantial commercial scale, which means homeowners should ask pointed questions about how residential and commercial workflows are sequenced within the company's crew dispatch system and whether residential project timelines are affected by larger commercial backlogs. Reasonable diligence questions include verifying the specific NABCEP individual credentialed for the homeowner's system design, confirming Ameren Missouri interconnection experience for the project's county, pinning down the workmanship warranty term, and asking which panel and inverter manufacturers the company is currently authorized to install. The fundamentals — St. Louis headquarters, 19 years of continuous operation, more than 3,000 installations, NABCEP-dense in-house team, dual-state licensing, and a comprehensive service offering — place StraightUp Solar firmly in the third-ranked position for 2026.
With a composite score of 73.0 out of 100, StraightUp Solar holds the third-ranked position in Missouri 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.
