SBS Solar

SBS Solar has built one of the deepest solar resumes in Western Montana, with installation work that traces back to 1985 when founder Dan Brandborg helped pioneer off-grid solar in the Bitterroot Valley through his earlier company Sunelco. Today SBS operates from offices at 1819 Kensington Avenue and 3225 Helena Drive in Missoula, and the firm is a Montana State Registered Contractor (license #158052) with a service territory that covers Missoula, Hamilton, Polson, and the broader Western Montana corridor.

What stood out to our research team is the bench of NABCEP-credentialed staff working under one roof. Dan Brandborg holds NABCEP Certified Solar PV Installer status (certification #031409-14), Ralph Walters carries an SEI-NABCEP credential, and Flynt Brandborg is a NABCEP Associate. That kind of multi-generational expertise is uncommon in a market the size of Montana, and it shows in the company's project portfolio, which spans residential rooftop and ground-mount systems, a U.S. Forest Service installation at Beaverhead-Deerlodge National Forest, and long-running residential systems that have generated more than 23 megawatt hours since 2010 according to documented case studies.

The numbers behind their reputation reinforce the technical resume. SBS Solar holds a 4.81 out of 5 rating across 86 reviews on SolarReviews with an Elite Expert Rating designation, and 83 of those reviews are five stars with zero ratings of three stars or lower. Their Google profile shows a perfect 5.0-star average across 140 reviews. The company is a Solar Energy Industries Association member, a NorthWestern Energy Qualified Installer, and a SolarWorld Authorized Installer, with SolarEdge featured prominently in their monitoring infrastructure. Customers should note that SBS is a smaller, deliberately scaled operation focused on Western Montana rather than statewide, so homeowners in Billings or eastern Montana may need to look elsewhere.

As a locally owned company with roots that predate the modern solar industry, SBS Solar brings firsthand familiarity with Montana's high-altitude conditions, NorthWestern Energy interconnection requirements, and the specific permitting workflows of Missoula County and surrounding jurisdictions.

With a composite score of 76.5 out of 100, SBS Solar holds the third-ranked position in Montana for 2026.
