All Energy Solar has become one of the most visible installers serving North Dakota homeowners despite headquartering its operations next door in St. Paul, Minnesota. Founded in 2009 and now based at 1264 Energy Lane, the company has completed more than 11,500 projects across its Midwest and East Coast service footprint, with North Dakota added as a dedicated residential service area in 2022. The company's announcement of ND expansion noted that all solar and battery storage projects are designed and installed in-house with licensed electricians, designers, and building contractors, rather than being outsourced to subcontractors — a structural choice that matters in a thin market like North Dakota, where customer-service handoffs are a common failure point.
What our research team weighed carefully is the credentials-to-volume ratio. All Energy Solar carries a NABCEP Board Certified PV Installation Professional designation, an A-plus rating from the Better Business Bureau, Solar Energy Industries Association membership, and EnergySage Elite Installer status — making it the only EnergySage-listed installer with a North Dakota residential service designation according to the marketplace's local-data pages. Customer feedback is broad and consistent: more than 2,200 five-star reviews across platforms and an EnergySage rating of 4.8 out of 5 on 370 verified reviews.
Prospective customers should weigh the trade-offs. All Energy operates from Minnesota without an in-state North Dakota office, which can translate to longer drive times for service calls in Bismarck, Dickinson, or Williston, and the company's pricing skews higher than the state average — EnergySage data places North Dakota cost-per-watt at $3.99 for the systems it lists. The company offsets distance through in-house design and permitting teams that handle Fargo's required electrical and building permits as part of the standard scope, and warranty coverage spans 25 years on panel performance, 25 years on inverter, and 10 years on workmanship.
For North Dakota homeowners who want a well-credentialed installer with thousands of completed projects rather than a smaller regional shop, All Energy Solar represents the most documented option in the state's limited installer field.
With a composite score of 77.4 out of 100, All Energy Solar stands as our top-ranked solar company in North Dakota for 2026.
ROOFTOP has operated in the Bismarck-Mandan area for 10 years, building a reputation as a dependable exterior contractor in a region where harsh weather puts roofing and energy systems to the test every winter. Originally established as a roofing and renovation company, ROOFTOP has expanded their service portfolio to include solar installation alongside siding, gutters, fencing, flooring, and general exterior work, making them a one-stop provider for homeowners looking to upgrade multiple building envelope components simultaneously.
Operating from their location on 26th Street NE in Bismarck, the company serves the broader south-central North Dakota market. Their roofing background gives them a practical advantage when it comes to solar panel mounting, particularly in a climate where freeze-thaw cycles, heavy snow loads, and sustained high winds can compromise improperly installed racking systems. A contractor who understands how a roof breathes, sheds water, and handles structural stress is better positioned to integrate solar without creating long-term problems.
The company's 4.9-star Google rating across 75 reviews reflects strong customer satisfaction, although the relatively modest review count is characteristic of the North Dakota market, where the residential solar customer base is still developing compared to states with more aggressive solar incentive programs. Customers have praised ROOFTOP for responsive communication, clean job sites, and straightforward pricing.
North Dakota presents unique challenges for solar adoption, including long winters with limited daylight hours and a utility rate structure that has historically made the payback period longer than in sunbelt states. Companies that succeed here tend to be pragmatic operators who set realistic expectations rather than overselling returns, and ROOFTOP's grounded approach fits that profile.
With a composite score of 68.54 out of 100, ROOFTOP earns the number two ranking among North Dakota solar installers for 2026.

Wegner Roofing and Solar is a family-owned roofing-plus-solar contractor that has operated in the Northern Plains since 2011 and now serves a five-state footprint covering Montana, North Dakota, South Dakota, Iowa, and Tennessee. The company's Bismarck office is located at 533 Airport Road in the Airport Road business corridor, and the firm reports more than 5,000 completed projects across all of its trade lines. In January 2026 Roofing Contractor Magazine placed Wegner at number 86 on its 2025 Top 100 Roofing Contractors list, a ranking that places it in the upper tier of mid-sized contractors nationally.
Our research team approached Wegner with the same scrutiny we apply to any roofing-plus-solar entry, because the brief specifically excludes roofing-only firms that name solar in their branding without actually performing photovoltaic installations. In Wegner's case the solar service line is published on dedicated landing pages for Bismarck, Mandan, and the broader ND footprint, and the company markets the full design-permit-install-maintenance scope rather than only solar shingles. That includes residential rooftop systems, ground-mount alternatives where appropriate, ongoing monitoring, and roof-tied warranty coordination — a practical advantage in a market where most roofs need replacement on a shorter cycle than a 25-year solar panel warranty.
Prospective customers should be candid about the limitations our review surfaced. The Wegner website does not publish specific NABCEP installer numbers, manufacturer-tier certifications, or named panel and inverter partnerships on its solar pages, and the broader brand identity remains roofing-first, with roofing-specific credentials from GAF, Owens Corning, IKO, and the NRCA more prominent than solar credentials. The company maintains a 4.9-star Google rating across 155 Bismarck reviews and a substantial review base on Yelp and BBB. Homeowners considering Wegner for solar specifically should ask pointed questions about the experience of the installation crew assigned to their project and request references for completed ND solar installations.
With a composite score of 70.2 out of 100, Wegner Roofing and Solar holds the third-ranked position in North Dakota 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.
