TL;DR: A solar-plus-battery backup system protects your New Orleans home during hurricane and storm outages by storing energy during the day and powering critical loads (refrigerator, fans, lights) when the grid goes down. Expect to invest $26,600–$38,000 after the 30% federal tax credit for a 10 kW solar array plus two batteries. Installation takes 8–12 weeks, and you'll need Entergy interconnection approval plus a City of New Orleans electrical permit.
Why New Orleans Homes Need Solar Storm Backup
When Hurricane Ida struck in August 2021, Hurricane Ida claimed more than 80 lives and knocked out power to over 600,000 Louisiana customers, with median outage times exceeding 12 days in the hardest-hit areas. (Nrel.gov) In some New Orleans neighborhoods, the outage lasted 10–14 days. No air conditioning in 95-degree heat. No refrigeration. No way to charge phones or power medical equipment.
That's the reality we face here in New Orleans. Our subtropical climate means we run air conditioning nearly year-round, and when a major storm hits, the grid can fail for weeks. Standard grid-tied solar panels won't help during an outage – they automatically shut off for safety reasons. But solar paired with battery backup changes everything.
A hybrid solar-plus-battery system keeps power flowing to your home even when Entergy's lines go down. During daylight hours, your panels recharge the battery. At night or during cloudy weather, the stored energy powers your essential loads. For many New Orleans homeowners, this means the difference between a manageable inconvenience and a genuine crisis.
Key Takeaway: Solar alone provides zero protection during a grid outage. Battery backup is what keeps the lights on when storms knock out Entergy's system.
How Does Solar Backup Work During a Storm Outage?
To understand why solar storm backup matters, you need to know how standard solar systems work – and why they fail when you need them most.
Grid-Tied Solar Without a Battery: No Storm Protection
Most residential solar installations are "grid-tied." Your panels generate electricity, an inverter converts it to AC power, and excess energy flows back to Entergy's grid. You get a bill credit for that exported power.
But here's the catch: when the grid goes down, most solar systems that lack a battery will also shut down. This is a safety requirement under the National Electrical Code (NEC Article 690). If your solar kept feeding power into a dead grid, utility workers repairing downed lines could be electrocuted. So the system shuts down automatically – leaving you without power, even though the sun is shining.
This anti-islanding protection is essential for grid safety. But it means standard solar provides zero backup during an outage.
Hybrid Solar + Battery: What Stays On During an Outage
A hybrid inverter changes the game. Instead of feeding excess solar power straight to the grid, it charges a battery first. When the grid fails, the hybrid inverter detects the outage and switches into "islanding mode" – operating independently, powering your home from stored battery energy and real-time solar generation.
Here's what that means in practice: during a storm outage, your refrigerator stays cold. Your ceiling fans run. Your lights work. Your phone charges. You can run a sump pump if needed. The system automatically prioritizes critical loads, so if the battery starts to deplete, it powers the most essential equipment first.
The hybrid inverter monitors grid voltage constantly. The moment Entergy restores power, it seamlessly reconnects and returns to normal operation. You don't have to do anything.
Key Takeaway: A hybrid inverter + battery system is the only way to keep solar power flowing during a grid outage. Standard grid-tied solar shuts down automatically for safety.
What Size Battery Do You Need for a New Orleans Home?
This is where most homeowners get stuck. How much battery capacity do you actually need?
The answer depends on two things: how much power you want to run, and for how long.
Understanding Your Load
Average New Orleans homes use 1,200–1,400 kWh per month – well above the national average of 893 kWh. That's because we run air conditioning constantly, and our humidity means dehumidifiers and fans run year-round.
But you don't need to back up your entire home. Most people choose "critical load" backup instead: refrigerator, a few lights, fans, phone/laptop charging, and maybe a sump pump. A typical New Orleans household's critical load during an outage is: Refrigerator: 150W, Lights (LED): 200W, Medical device or sump pump: 100W, totaling 450W continuous, or 10.8 kWh per day.
A 13.5 kWh battery (like a Tesla Powerwall 2) powering a 400W critical load runs for about 33 hours. That's roughly one full day plus one night of backup. With solar recharging during daylight, a single battery can sustain critical loads indefinitely during a multi-day outage.
Battery Options for New Orleans
Here's what's available and what it costs:
| Battery | Capacity | Continuous Power | Warranty | Best For |
|---|---|---|---|---|
| Tesla Powerwall 2 | 13.5 kWh | 5 kW | 10 years | Whole-home or critical loads; most popular |
| Enphase IQ Battery 5P | 5 kWh | 3.84 kW | 10 years | Stackable; start small, expand later |
| Franklin Home Power | 13.6 kWh | 7.6 kW | 10 years | High power output; good for AC backup |
Rule of thumb: Plan for 20 kWh of battery storage minimum in New Orleans to cover 5 days of critical loads during a hurricane outage. One battery covers critical loads for 24–36 hours with solar recharge. Two batteries give you 2–3 days of independence. Three or more batteries enable whole-home backup for extended outages.
For New Orleans, where post-storm outages can last 10+ days, most homeowners choose two batteries for critical loads. That's enough to keep essentials running while you wait for grid restoration, and it's more affordable than backing up the entire house.
How Much Does Solar Storm Backup Cost in New Orleans?
Let's talk real numbers.
System Costs
A typical residential solar system in Louisiana ranges from $2.35 to $3.15 per watt before incentives. That puts an 8 kW system around $18,800 and a 12 kW system around $25,200 on average. Battery add-ons run $10,000–$16,000 installed per unit. A Tesla Powerwall 2 typically costs $12,000–$14,000 installed; an Enphase system is similar.
Example: 10 kW solar + 2 Tesla Powerwall 2 batteries
- Solar: ~$20,000
- Batteries (2 units): ~$18,000
- Gross total: ~$38,000
The Federal Tax Credit Changes Everything
The Inflation Reduction Act provides a 30% federal Investment Tax Credit (ITC) for solar-plus-storage systems through at least 2032. That credit applies to both panels and batteries.
Same system after 30% ITC:
- $38,000 × 0.70 = $26,600 net cost
That's a $11,400 reduction just from the federal credit. You claim it on your federal tax return; you don't need to pay it upfront.
Louisiana Incentives (Limited)
Louisiana does not currently have an active state solar tax credit. The previous Louisiana Residential Solar Energy Systems Tax Credit (Act 309) expired at the end of 2021 and was not renewed. So the 30% federal credit is your main incentive.
Entergy New Orleans does offer net metering under its Schedule NM tariff, which provides bill credits for excess solar energy you export to the grid. The credit value depends on your rate schedule, but it helps offset your system cost over time.
Payback Timeline
If your current Entergy bill is $180/month ($2,160/year), and your 10 kW solar system generates enough to offset 80% of that, you'd save about $1,728/year. After the federal tax credit, your net cost is $26,600.
Payback: roughly 15 years without battery, 12–14 years with battery when you factor in the avoided outage costs and resilience value.
That's longer than some solar markets, but it's the reality here in New Orleans. Our high electricity consumption works in solar's favor, but our cloud cover and humidity reduce generation slightly.
Financing Options
Most homeowners don't pay cash. Here's what's available:
- Solar loans: $0-down financing with no prepayment penalty. Monthly payments typically $300–$500 for a 10 kW system.
- PACE financing: Property Assessed Clean Energy loans available in Louisiana. Repaid through property tax assessments; no upfront cost.
- Home equity lines: If you have equity in your home, a HELOC can fund solar at competitive rates.
- Leasing: Some installers offer leases, but you don't own the system and can't claim the federal tax credit.
For storm backup, ownership matters. You want to own the battery so you control it during an outage. Leased systems may have restrictions.
Is Your Roof Storm-Ready for Solar Panels?
Before you install solar, your roof has to pass a hurricane-readiness check.
Wind Rating Requirements
New Orleans falls within ASCE 7-16 Wind Speed Map Risk Category II, requiring design wind speeds of 150–160 mph for residential structures. That means your solar racking system must be engineered to withstand those wind loads.
IronRidge and Unirac racking systems publish wind-rated load tables. Installers use their Design Assistant tools to generate stamped engineering letters specific to your roof and location. This isn't generic – it's site-specific structural engineering.
Roof Age and Condition
Most installers require at least 10 years of remaining roof life before installation. If your roof is older than 15–20 years, you should replace it before going solar. Removing and reinstalling panels to replace a roof underneath costs $2,000–$4,000.
Common New Orleans Roof Types
- Asphalt shingle (most common): Standard penetrating mounts work fine. Roofer must seal all penetrations properly.
- Flat/TPO roofs (common in commercial, some residential): Ballasted mounts (no penetrations) or special penetrating systems. More expensive but avoids roof damage.
- Tile roofs (older homes, some neighborhoods): Requires specialized tile-cutting and flashing. More labor-intensive; plan extra cost.
Combining Roof Replacement with Solar
If your roof needs replacement anyway, do it before solar. But here's a pro tip: some installers can coordinate roof replacement and solar installation together, which saves money on labor and logistics. You're only paying for one roof access and one permitting process.

Not all installers are equal. Here's how to vet them.
Licensing and Credentials
Check the Louisiana State Licensing Board for Contractors (LSLBC) database. Your installer must hold an active electrical contractor license. This is non-negotiable – it's the law.
NABCEP (North American Board of Certified Energy Practitioners) Board Certified PV Installation Professional (BCPVIP) certification is the industry's highest credential. It's not required by law, but it signals serious competency.
Local Experience Matters
Ask these questions:
- How many systems have you installed in New Orleans? You want someone with local experience, not a national company sending a crew from out of state.
- Have you worked with Entergy interconnection before? Entergy's Rule 15 process can be tricky. Your installer should know it inside out.
- Do you have experience with post-storm service? If your system fails during an outage, can they respond quickly?
- What's your permit pull history with the City of New Orleans? Ask for references from recent New Orleans installs.
Red Flags
- Unusually low quotes (15–20% below market is normal; 40% or more below is suspicious).
- Pressure to sign the same day.
- No local address or phone number.
- Unwillingness to provide references.
- Vague about warranty or service terms.
Get Multiple Quotes
Get at least three quotes. Price variation of 15–20% is normal and reflects different equipment choices and labor costs. Anything wider than that deserves explanation.

Frequently Asked Questions About Solar Storm Backup in New Orleans
How much does a solar storm backup system cost in New Orleans?
Direct Answer: A 10 kW solar array plus two batteries costs approximately $38,000 gross; after the 30% federal tax credit, expect to pay around $26,600 net out-of-pocket.
The exact cost depends on your roof type, electrical setup, and battery choice. Financing options like solar loans and PACE programs can reduce or eliminate upfront costs. Get a free quote from a local installer to see what your specific home qualifies for.
Will my solar panels keep working during a hurricane?
Direct Answer: Solar panels themselves are extremely durable and can withstand 150+ mph winds when properly mounted. However, standard grid-tied solar systems automatically shut off when the grid goes down – so you won't have power even if the panels are generating.
A hybrid inverter with battery backup solves this. Your system detects the outage and switches to islanding mode, powering your home from stored battery energy and real-time solar generation. The panels keep working; the battery keeps you powered.
How many days can a solar battery backup power my home after a storm?
Direct Answer: A single 13.5 kWh battery powering critical loads (refrigerator, fans, lights, phone charging) at ~400W continuous draw provides about 33 hours of runtime – roughly one full day plus one night.
With solar recharging during daylight, one battery can sustain critical loads indefinitely during a multi-day outage. Two batteries give you 2–3 days of complete independence from the grid. For whole-home backup (including AC), you'd need three or more batteries.
Is solar storm backup better than a gas generator for New Orleans homes?
Direct Answer: Solar backup is quieter, requires no fuel storage or maintenance, and works automatically. Generators are cheaper upfront but need regular maintenance, fuel, and manual operation.
Many New Orleans homeowners use both: solar-plus-battery for daily resilience, and a backup generator for extended outages. Solar is cleaner and more convenient; generators are a good insurance policy for worst-case scenarios.
What federal or Louisiana state incentives apply to solar battery backup?
Direct Answer: The federal Investment Tax Credit (ITC) covers 30% of solar-plus-storage system costs through at least 2032. Louisiana does not currently have an active state solar tax credit.
Entergy New Orleans offers net metering, which provides bill credits for excess solar energy you export to the grid. PACE financing is also available in Louisiana, allowing $0-down financing repaid through property tax assessments.
How long does it take to install solar with battery backup in New Orleans?
Direct Answer: Installation typically takes 2–4 weeks on-site. However, the full timeline from quote to energization is 8–12 weeks, including permitting and Entergy interconnection approval.
City of New Orleans electrical permits usually take 2–3 weeks. Entergy's Rule 15 interconnection process can take 6–8 weeks. Your installer handles both, but it's not instantaneous.
Does Entergy New Orleans allow solar battery backup systems?
Direct Answer: Yes. Entergy New Orleans allows solar-plus-battery systems under its Rule 15 distributed generation tariff. Battery-backed systems must meet anti-islanding requirements and receive Entergy approval before energization.
Your installer handles the interconnection application. Entergy will inspect your system to verify it meets safety standards, then issue approval to energize.
