Solar in Louisiana: Hurricanes, High Bills, and a Surprising Solar Case

Louisiana is not the first state people think of for solar. Hurricanes, humidity, and a historically oil-and-gas economy make it feel like the wrong fit. But Louisiana has something that changes the solar math completely: expensive electricity. The state's average residential rate has climbed to $0.13-$0.16/kWh, well above the national average, and Entergy customers in particular have seen aggressive rate increases in recent years.

Combine high bills with decent sun exposure, and Louisiana becomes a more interesting solar market than most people expect. Here is the real picture for 2026.

The Good News

Strong Solar Resource

Louisiana averages 4.7-5.3 peak sun hours per day. Southern Louisiana near New Orleans and Baton Rouge gets the higher end of that range. That is better than the national average and significantly better than states like Massachusetts and New Jersey that have thriving solar markets. The sun is not the problem here.

High and Rising Electricity Rates

This is the biggest driver of solar economics in Louisiana. Entergy Louisiana, the dominant utility, has raised rates significantly over the last several years. Residential customers are paying $0.13-$0.16/kWh, and some rate classes exceed that. When electricity is expensive, every kWh your panels produce is worth more.

Entergy has also filed for additional rate increases to cover infrastructure upgrades and storm recovery costs. The trend is upward, and there is no sign of it reversing.

Sales Tax Exemption

Louisiana exempts solar energy systems from state sales tax. At the state rate of 4.45% (plus applicable local taxes), this saves roughly $1,000-$1,400 on a typical residential system. It is not a game-changer, but it reduces your upfront cost.

Property Tax Exemption

Residential solar installations in Louisiana are exempt from additional property tax assessment. Your property taxes do not increase when you add panels.

The Challenges

The State Tax Credit Is Gone

Louisiana once had one of the best state solar tax credits in the country — 50% of system cost up to $12,500. That program expired in 2018 and has not been renewed. With the federal ITC also expired as of 2026, Louisiana homeowners now have zero direct tax incentives for solar. This is a major shift from the boom years of 2015-2017 when Louisiana was one of the cheapest states to go solar after credits.

Net Metering Is Under Pressure

Louisiana has net metering, but the terms have been tightening. Entergy's current residential net metering program credits excess solar exports, but the utility has pushed to reduce compensation for exported power. The Louisiana Public Service Commission has been receptive to utility arguments about cost-shifting.

If you install now, your net metering agreement should be grandfathered under current terms. But the long-term trajectory is toward lower export compensation. This makes self-consumption and batteries increasingly important.

Hurricane Exposure

This is the elephant in the room. Louisiana faces direct hurricane hits more frequently than almost any other state. Modern solar panels withstand 140-160 mph winds, and mounting systems are engineered to local building codes that already account for hurricane risk. But:

• Flying debris can damage panels regardless of wind rating
• Extended power outages after major storms make battery backup extremely valuable
• Some insurers charge higher premiums or require riders for rooftop solar in high-wind zones
• Roof condition matters enormously — panels on a compromised roof are more vulnerable

After Hurricane Ida in 2021, many solar installations in the affected areas survived intact while the grid was down for weeks. Homeowners with battery backup had power. Those without batteries had functional panels that could not operate because grid-tied systems shut down during outages. A home battery like the Tesla Powerwall is worth serious consideration in Louisiana — it turns your solar panels into a functional backup system when the grid goes down, which in hurricane country is not a matter of "if" but "when."

The Louisiana Solar Math (2026)

Typical 8kW system:

• Installed cost: $23,200 ($2.90/watt)
• Federal ITC: $0 (expired January 1, 2026)
• State credits: $0
• Sales tax savings: ~$1,030
• Net cost: ~$22,170

Annual production: ~11,600 kWh

Average Entergy residential rate: $0.14/kWh

Annual savings: $1,625 (assuming 70% self-consumption, 30% exported at full retail under current net metering)

Payback period: 13-15 years

25-year savings: $18,000-$28,000 (depending on rate increases)

If Entergy rates continue climbing at 4-5% annually — which is consistent with recent trends and approved rate increase filings — the payback shortens to 11-13 years and 25-year savings increase substantially.

Getting quotes from multiple installers is especially important in Louisiana, where pricing and hurricane-rated mounting options vary. EnergySage makes it easy to compare local options.

When Solar Makes Sense

Install if:

• Your monthly Entergy bill exceeds $150 (the higher, the better the math)
• You plan to stay in the home 10+ years
• You want to lock in net metering terms before potential policy changes
• You are adding a battery for hurricane backup — this provides both financial and practical value
• Your roof is in excellent condition and rated for your wind zone
• You have confirmed solar coverage with your homeowner's insurance

Wait or skip if:

• Your electricity bill is under $100/month
• Your roof needs replacement within the next 5 years — do the roof first
• You are in an extremely high-risk flood zone where the home itself is vulnerable
• You cannot confirm insurance coverage for the panels at a reasonable cost
• You plan to sell the home within 5 years

Key Takeaways

• Louisiana's high electricity rates ($0.13-$0.16/kWh) are the primary driver making solar viable even without incentives
• No state tax credit and no federal ITC — the generous Louisiana credit expired in 2018 and is not coming back
• Sales and property tax exemptions provide modest but real savings
• Net metering is available but facing pressure — installing sooner locks in better terms
• Hurricane resilience is a real consideration — panels are tough, but battery backup transforms solar from a grid-tied luxury into a genuine resilience tool
• Typical payback: 13-15 years with 25-year savings of $18,000-$28,000
• Rising Entergy rates are the wildcard — if the trend continues, solar economics improve significantly over time
