Mississippi Solar, LLC has spent more than a decade and a half building one of the longest-tenured dedicated solar practices in the state. The company was founded in 2008 by Will and Carolyn Hegman and registered with the Mississippi Secretary of State in 2009, distinguishing itself as the first commercial contractor in Mississippi to hold a Solar and Wind Specialty License. Will Hegman's solar background traced back to the 1980s, when he designed and installed wind and solar systems on his sailboat in the Caribbean before bringing those skills back to his home state. After his death, the company was sold to current owners John and Virginia Wilbanks — both Mississippi natives with graduate degrees from Delta State and the University of Mississippi — who relocated operations from the Jackson area to Eupora, where the office and warehouse now sit at 307 Vance Road.
What stood out to our research team is the technical and operational depth Mississippi Solar carries in a state where many search-result "solar" companies turn out to be HVAC contractors, window-film installers, or out-of-state lead resellers. Mississippi Solar holds both NABCEP certification and a Commercial Electrical Contractor and Residential Builder license, and the team handles on-grid and off-grid PV design and installation, energy storage, EV charging at Level 2 and Level 3, and ongoing system monitoring, maintenance, and service. The equipment lineup is genuinely tier-one: REC Solar, Q CELLS, and Mission Solar panels paired with Sol-Ark, Enphase, SolarEdge, Schneider Electric, SMA, and Midnight Solar power electronics, Pytes and Renon battery storage, and SnapNRack and Sinclair racking. The company is also a Generac Power Pro Elite Plus dealer, the manufacturer's highest dealer tier for standby generation.
The numbers behind their customer satisfaction reinforce the operational story. A 4.9-star Google rating across 95 reviews reflects consistent quality across residential rooftops, poultry farms, and even sports-arena installations, and Synchrony and Acorn Finance provide loan options for homeowners who do not pay cash. Statewide solar coverage out of Eupora gives Mississippi Solar firsthand familiarity with the state's permitting and interconnection patchwork.
With a composite score of 78 out of 100, Mississippi Solar, LLC stands as our top-ranked solar company in Mississippi for 2026.
Solar Alternatives, Inc. is a Gulf Coast solar and energy-management firm that operates across Louisiana, Mississippi, Texas, Alabama, Arkansas, Florida, and Tennessee from a headquarters at 5804 River Oaks Road South in New Orleans. The company has served the region since 2008 and was named to the Inc. 5000 list of fastest-growing private companies in 2022, an external benchmark of sustained revenue growth that few solar installers in the Deep South have achieved. Founder and president Jeffrey Cantin holds a Bachelor of Science in Electrical Engineering from Rice University, multiple statewide master electrical licenses, and NABCEP PV and Thermal Certification, and serves on the board of the Gulf States Renewable Energy Industries Association, the regional SEIA chapter.
For Mississippi homeowners, the relevant detail is that Solar Alternatives runs a dedicated Jackson office in addition to a Biloxi service footprint, which means the Mississippi presence is staffed rather than a remote-dispatched coverage area. The company designs and installs residential and commercial PV systems, Tesla Powerwall battery backup, Tesla Solar Roof, and EV chargers, and Cantin's NABCEP-credentialed quality-control team carries additional NABCEP PV Associate certification on the technical staff. Solar Alternatives is also a Better Business Bureau accredited business and participates in community work including the Community Lighthouse Initiative and a workforce-training partnership with Louisiana Green Corps.
Our research team did flag two items worth raising during the sales process. First, the company's customer rating sits at 4.3 stars across 96 Google reviews — a respectable score but the lowest of the three top-ranked Mississippi installers in this cycle — and prospective customers should ask pointed questions about project management, communication, and post-install responsiveness. Second, Solar Alternatives publishes coverage of "comprehensive warranties" and "zero-down and long-term payment options" on its Mississippi-facing pages without specifying warranty length or financing partners; homeowners should confirm those terms in writing before signing.
With a composite score of 75 out of 100, Solar Alternatives, Inc. holds the second-ranked position in Mississippi for 2026.
Solar South LLC operates out of 5263 Old Highway 11 in Hattiesburg and focuses its solar work on the commercial, agricultural, government, and residential sectors across southern and central Mississippi. The company's published service map covers Jackson, Hattiesburg, Laurel, McComb, and Magee — a corridor that spans the Pine Belt and reaches into the south Mississippi farm economy where row-crop and poultry operations face some of the highest electricity bills in the state. General manager Ryan Ladner, a University of Southern Mississippi graduate, leads day-to-day operations and has positioned the firm specifically around using solar to offset the kind of large monthly utility loads that agricultural and small commercial customers carry.
What stood out to our research team is Solar South's emphasis on USDA grant-funded projects. The company guides agricultural and rural small-business customers through the USDA Rural Energy for America Program application process, which can fund a significant portion of a qualifying solar installation through federal grant dollars rather than financed debt. That is a meaningful operational specialization in a state where REAP-eligible properties are abundant but where most solar installers have neither the patience nor the paperwork familiarity to shepherd a grant application through to award. Solar South also handles standard residential rooftop work alongside its commercial and government-facility portfolio, with project scope managed end-to-end from consultation and site assessment through final commissioning.
Prospective customers should weigh the trade-offs honestly. Solar South does not publish panel brands, inverter platforms, battery options, warranty terms, certifications, or financing partners on its website, and the company carries no verified Google review profile, which limits the public signal available to homeowners doing diligence. The team's Mississippi roots, regional permitting familiarity, and USDA grant fluency are real assets, but interested customers should ask pointed questions during the proposal stage about equipment selections, NABCEP credentials, workmanship and production warranties, and references from completed projects in their sector.
With a composite score of 72 out of 100, Solar South LLC holds the third-ranked position in Mississippi 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.
