Louisiana pays about 2.7¢ for every kilowatt-hour your panels export and charges about 11¢ for the power you buy, so nobody should sell you solar here as an income stream. What Louisiana solar actually is, done right, is hurricane insurance that pays part of its own premium: a solar-plus-battery home keeps the refrigerator and the window unit running through a multi-day outage and trims the bill all year. The three companies below have been building exactly that on Gulf roofs since 2008 or earlier.
Solar Alternatives, South Coast Solar and JEH Solar are the three vetted Louisiana installers in our network. All three are storm-country natives who install battery backup as a matter of course, which is the qualification that matters in a state where exports earn 2.7¢ and hurricane season is a certainty.
Our Top 3 Solar Companies in Louisiana
Each company below is a Gulf Coast operation we verified on its own published record and a working website this week. Placement is never sold.
Solar Alternatives
A Gulf Coast fleet operator rather than a sales shop: 2,000+ systems under active maintenance across 11+ Louisiana service cities, with NABCEP-certified O&M staff and licensed electricians on payroll. When a named storm rolls through, the company that monitors your system is the company that answers the phone.
South Coast Solar
A New Orleans electrical contractor that grew into solar, Tesla Powerwall Certified, with factory-trained and nationally certified installers. The signature promise is the one Louisiana roofs need most: guaranteed leak-proof flashing on every penetration, because a roof that survives the wind still has to survive the rain.
JEH Solar
Lafayette’s answer, with about 30 years of electrical and solar craft behind it and a 25-year workmanship warranty that outlasts most mortgages. NABCEP-certified, license numbers published on its own site, and fluent in the backup generators and battery systems that Acadiana outages demand.

A 2.7¢ Export Rate Makes the Battery the Business Case
The Public Service Commission ended retail net metering for systems connected after December 31, 2019. A new Louisiana system sells its surplus at avoided cost, roughly 2.7¢ per kilowatt-hour at Entergy under the LPSC’s published schedule, while the retail power it offsets costs about 11¢. That 4-to-1 gap writes the design brief for every installer on this page: size panels to daytime usage, and let a battery move afternoon production into the evening instead of donating it to the grid. The same battery is what keeps the lights on when a named storm takes the grid down, which in Louisiana is not a hypothetical.

Frequently Asked Questions
Solar Alternatives, South Coast Solar and JEH Solar are the three verified Louisiana installers in our network for 2026: Solar Alternatives for its monitored 2,000-system fleet across the Gulf Coast, South Coast for electrical-contractor craft and guaranteed flashing in the New Orleans metro, and JEH for Acadiana coverage backed by a 25-year workmanship warranty.
Rarely. Cheap 11¢ retail power and 2.7¢ exports stretch a panels-only payback long unless your daytime self-consumption is unusually high, and grid-tied panels shut off in an outage anyway. The version of Louisiana solar that earns its price is solar plus storage, valued as hurricane backup that also cuts the bill.
PosiGen, the Louisiana-headquartered company that made solar leases a household word here, is no longer operating, one of several large solar operators to fail in recent years. It is the clearest local argument for choosing established installers who will exist when your warranty claim does, which is exactly what our vetting screens for.
Our national installer rankings hold every market we vet, Louisiana included.
