South Coast Solar

South Coast Solar has spent the better part of two decades building what is now the most credentialed dedicated residential solar practice headquartered in Louisiana. Founded in 2007 and based in Metairie, the company has completed more than 4,000 residential solar installations across Louisiana, Georgia, North Carolina, and South Carolina, and operates from its Ridgelake Drive office serving the New Orleans metro and the broader Gulf Coast. The company is one of only 38 Master SunPower Dealers nationwide — a tier-one manufacturer designation reserved for installers with sustained installation volume, customer satisfaction metrics, and technical-team certifications — and the in-house roster includes NABCEP-certified individuals including PV Installation Professional credential holders.

What stood out to our research team is the depth of the equipment and warranty stack. South Coast Solar designs and installs SunPower residential PV systems alongside Tesla Powerwall battery storage and EV charging — a hardware combination that puts homeowners on the durable end of the tier-one panel market and provides credentialed installation for the storage equipment Louisiana homeowners increasingly want for hurricane resilience. The company's published process emphasizes leak-proof flashing systems and aesthetic attention to roof penetration detailing, which translates to lower warranty exposure on a category of failure that drives a disproportionate share of solar customer complaints in the industry overall.

Prospective Louisiana customers should know that South Coast Solar is one of the few in-state installers with a verifiable two-decade operating history, demonstrated multi-state engineering discipline, and direct Tesla and SunPower manufacturer relationships. Reasonable diligence questions include confirming the specific NABCEP individual credentialed for the project, verifying the company's current dealer-tier standing with SunPower under the post-bankruptcy Complete Solaria operating model, and pinning down Entergy New Orleans or Entergy Louisiana interconnection experience for the homeowner's specific service territory. The fundamentals — Louisiana headquarters, 18 years of continuous operation, more than 4,000 installations, Master SunPower Dealer designation, NABCEP-credentialed installers, and Tesla Powerwall certification — make South Coast Solar our top-ranked solar installer in Louisiana for the 2026 ranking cycle.

With a composite score of 80.0 out of 100, South Coast Solar stands as our top-ranked solar company in Louisiana for 2026.
