Quick Answer
Louisiana's 2026 solar incentives are limited but usable. Homeowners get a 100% property tax exemption under La. Rev. Stat. § 47:1706. Most utilities pay avoided-cost export credits of roughly 2.6 to 2.8 cents per kWh. New Orleans still offers full retail net metering. The federal residential tax credit expired after 2025.
Louisiana homeowners use more electricity than almost any other state. The average household consumed about 1,202 kWh per month in 2024, the highest in the continental United States, according to the U.S. Energy Information Administration. Hot, humid summers keep air conditioners running for months. That high usage should make solar attractive, but the state’s incentive stack is thin.
The federal Residential Clean Energy Credit expired for homeowner-owned systems at the end of 2025. Louisiana has no active state income tax credit and no statewide rebate. What remains is a property tax exemption, a few local programs, and net billing. Net billing pays export credits at roughly one-fifth to one-quarter of the retail rate. The one bright spot is New Orleans, where full retail net metering still applies for Entergy New Orleans customers.
This guide covers every active Louisiana solar incentive in 2026, how net billing changes ROI, and how to model realistic payback without the federal credit.

Louisiana Solar Incentives at a Glance — 2026
Louisiana is not a high-incentive solar market. The same 7 kW system can have very different economics in New Orleans, Baton Rouge, Lafayette, or Shreveport because the export credit and fixed fees differ. The table below summarizes the main programs active in 2026.
| Incentive | Type | 2026 Status | Typical Value |
|---|---|---|---|
| Federal residential ITC | Tax credit | Expired | $0 for cash or loan residential purchases |
| Federal Section 48E | Commercial tax credit | Active, deadlines apply | 30% for eligible commercial, lease, or PPA systems |
| Louisiana property tax exemption | Tax exemption | Active | 100% of added system value excluded |
| Louisiana state income tax credit | Tax credit | Expired | $0 for new installations |
| Legacy net metering | Bill credit | Grandfathered only | Full retail rate through 2034 for pre-2020 systems |
| Net billing / avoided cost | Bill credit | Active for new systems | ~2.6 to 2.8 cents per kWh exported |
| Entergy New Orleans net metering | Bill credit | Active for eligible customers | Full retail rate for exports |
| Solar for All NOLA | Low-income program | Active | Reduced-cost solar and battery options for qualifying residents |
| HELP loan | State financing | Concluded December 2023 | No longer accepting new applicants |
Louisiana had about 1,661 MW of total solar installed as of early 2026, enough to power roughly 166,000 homes, according to SEIA. The state ranked 32nd nationally in cumulative capacity but added enough capacity in 2024 to rank 15th in annual additions.
Key Takeaway
Louisiana solar works in 2026, but the math is driven by high household consumption, low retail rates, and weak export credits. The federal residential tax credit is gone, so accurate utility-specific modeling matters more than ever.
The Federal ITC Is Gone for Homeowners. What Still Works?
The 30% federal Residential Clean Energy Credit under Internal Revenue Code Section 25D expired on December 31, 2025. Homeowners who buy solar with cash or a loan in 2026 cannot claim it. This is the single largest change in Louisiana’s solar math.
Commercial, third-party-owned, and leased systems may still access the federal Investment Tax Credit under Section 48E. The usual safe-harbor rules apply: construction must begin before July 4, 2026, or the system must be placed in service by December 31, 2027. Lease and power-purchase-agreement providers can pass a portion of that credit through as lower monthly payments. That makes third-party ownership more attractive in Louisiana now than it was when the residential ITC was available.
For cash and loan buyers, the federal credit is gone. The rest of the stack must carry the project. That means every installer proposal in Louisiana should lead with the property tax exemption, net billing or net metering value, and any available local incentive. Do not lead with a federal tax credit that no longer exists.
How Louisiana Net Metering and Net Billing Work
Louisiana enacted net metering rules in 2003 and updated them in 2019. The current framework splits customers into two groups.
Legacy Net Metering Customers
Systems interconnected before December 31, 2019, receive full retail-rate credits for monthly net excess generation through December 31, 2034. That is 15 years of grandfathered retail-rate treatment. If you are buying a home with one of these systems, the value of the grandfathered tariff transfers with the meter.
New Net Billing Customers
For systems interconnected after December 31, 2019, the rules changed. Customers pay the full retail rate for all electricity imported from the grid. Excess solar exported to the grid is credited at the utility’s avoided cost. The Louisiana Public Service Commission publishes these avoided-cost rates annually.
The 2026 avoided-cost rates for major LPSC-jurisdictional utilities are approximately:
| Utility | Typical Retail Rate | 2026 Avoided Cost Export Credit |
|---|---|---|
| Entergy Louisiana | ~12 to 14 cents/kWh | ~2.77 cents/kWh |
| CLECO Power | ~12 to 14 cents/kWh | ~2.76 cents/kWh |
| SWEPCO | ~11 to 13 cents/kWh | ~2.74 cents/kWh |
| DEMCO | ~12 to 14 cents/kWh | ~2.76 cents/kWh |

What the export gap means for design
A kilowatt-hour exported at 2.7 cents and later bought back at 13 cents loses about 80% of its value. The safest design rule is to size the system for roughly 80% to 100% of annual usage and minimize exports. Oversized systems produce cheap credits that do not help pay back the loan.
Louisiana Property Tax Exemption
Louisiana Revised Statute § 47:1706 exempts solar energy systems attached to owner-occupied residential buildings from ad valorem taxation. The home itself can still appreciate for other reasons, but the assessed value cannot include the solar equipment.
This matters because Louisiana property tax rates vary by parish but can reach 100 mills or more. A $25,000 solar system could otherwise add $250 to $400 per year to the tax bill. Over 25 years, that is $6,250 to $10,000 in avoided taxes.
The exemption is generally automatic once the assessor recognizes the system as solar. Homeowners should keep installation documentation in case the assessor asks for it. There is no separate annual application in most parishes.
New Orleans: The Exception to State Rules
Orleans Parish operates under the New Orleans City Council rather than the Louisiana Public Service Commission. Entergy New Orleans customers have historically had stronger solar rules than the rest of the state.
Full Retail Net Metering
Entergy New Orleans has offered full retail-rate net metering to residential customers. Under this structure, one kilowatt-hour exported earns one kilowatt-hour of credit. That makes solar-only systems far more economically attractive than in Entergy Louisiana territory with avoided-cost credits. Customers should verify current program availability and interconnection timelines directly with Entergy New Orleans before signing a contract.
Solar for All NOLA
The City of New Orleans runs Solar for All NOLA. The program expands access to solar and battery storage for low- and moderate-income residents. It partners with local installers and offers free feasibility studies, leasing and financing options, and low-cost energy efficiency upgrades. It aims for 1,400 individual installations or 10 MW of solar capacity by 2030.
Battery incentives
In late 2025, the New Orleans City Council approved a distributed energy resource program with significant battery funding. Early reports indicate upfront battery incentives of roughly $75 per kWh of storage capacity, plus the possibility of ongoing bill credits for participating in grid services. A standard 13.5 kWh battery could receive an incentive of roughly $1,000. Program details and application procedures should be confirmed with the City of New Orleans or an approved installer.
Cost, ROI, and Payback Scenarios by Utility Territory
Numbers make the policy shift concrete. Take a 7 kW solar system on a Baton Rouge home served by Entergy Louisiana. The system costs roughly $21,000 before incentives. Annual production is roughly 9,500 to 10,500 kWh in South Louisiana.
Scenario 1: Entergy Louisiana with net billing
- System cost: $21,000
- Annual production: 10,000 kWh
- Self-consumed: 6,000 kWh at ~13 cents/kWh = $780/year
- Exported: 4,000 kWh at ~2.77 cents/kWh = $111/year
- Total first-year savings: ~$891
- Simple payback: ~23 to 24 years
This assumes no battery and no federal credit. The payback is long because the export credit is weak.
Scenario 2: Entergy New Orleans with full retail net metering
- System cost: $21,000
- Annual production: 10,000 kWh
- Full retail offset at ~13 cents/kWh = $1,300/year
- Simple payback: ~16 years
With full retail net metering, the same system pays back roughly seven years faster.
Scenario 3: New Orleans with battery and incentives
- System cost: $21,000 + $15,000 battery = $36,000
- Battery incentive: ~$1,000
- Net cost: $35,000
- Annual savings with high self-consumption: ~$1,600 to $1,800
- Simple payback: ~19 to 22 years
The battery improves self-consumption but adds significant cost. The financial case depends heavily on the battery incentive and the value of backup power during outages.
The opinion most installers miss
Louisiana installers often quote payback using national averages or outdated federal credit assumptions. That is a mistake. The only honest proposal in Louisiana models the customer’s specific utility, actual retail rate, and actual avoided-cost export credit. A system that pays back in 9 years in California can take 20 years in Baton Rouge under net billing. Use the SurgePV generation and financial tool to build territory-specific proposals that reflect this reality.
Financing Options in Louisiana
The right financing structure matters in Louisiana because payback periods are longer than the national average.
Cash purchase
Cash delivers the highest lifetime savings and the simplest ownership structure. A homeowner who can afford the upfront cost avoids interest and owns the system outright. In Louisiana, cash payback periods typically range from 10 to 16 years for favorable territories and 14 to 20 years for net billing territories.
Solar loans
Solar loans spread the cost over 10 to 25 years. Monthly payments often replace the electric bill, but interest reduces total savings. A $21,000 system financed at 7% over 20 years has monthly payments of roughly $163. If the pre-solar electric bill was $170 per month, the homeowner breaks even on cash flow but pays more over the life of the loan.
Leases and power purchase agreements
Leases and PPAs require little or no upfront payment. The provider owns the system and claims any available commercial tax credits. The homeowner pays a fixed monthly amount or a per-kWh rate. Total lifetime savings are usually lower than cash or loan ownership, but the upfront barrier is minimal. In 2026, third-party ownership may be the only way to capture federal tax benefits in Louisiana.
Home Energy Loan Program
The Louisiana Home Energy Loan Program, or HELP, offered low-interest loans for energy improvements. The program concluded in December 2023 and is no longer accepting new applicants, according to the Louisiana Department of Energy and Natural Resources. Homeowners should not rely on websites that still list HELP as active.
Common Mistakes and How to Avoid Them
Assuming the federal tax credit still exists
Many homeowners and some installers still open conversations with “30% federal tax credit.” For cash and loan residential systems placed in service in 2026, that credit is gone. Verify the customer’s tax situation and ownership structure before mentioning any federal benefit.
Oversizing the system for net billing
Because exports are worth only 2.6 to 2.8 cents per kWh, oversized systems produce cheap credits. Size the system to match on-site consumption rather than maximize production.
Ignoring utility-specific rules
Entergy Louisiana, Entergy New Orleans, CLECO, SWEPCO, DEMCO, and Lafayette Utilities System all have different rate structures and fees. Lafayette Utilities System, for example, has implemented a solar-specific rate class with higher monthly fixed charges. Always model the specific utility.
Relying on outdated state incentive lists
Several websites still list a Louisiana state solar tax credit or the HELP loan. The state tax credit expired years ago, and HELP concluded in 2023. Use current sources such as the Louisiana Public Service Commission, DSIRE, or the specific utility.
Frequently Asked Questions
What solar incentives are available in Louisiana in 2026?
Louisiana homeowners can use the 100% property tax exemption for solar energy systems under La. Rev. Stat. § 47:1706. Entergy New Orleans customers may still qualify for full retail-rate net metering. Most other utilities offer net billing with avoided-cost credits near 2.6 to 2.8 cents per kWh. There is no active state income tax credit. The federal residential tax credit under Section 25D expired for systems placed in service after December 31, 2025.
Does Louisiana have net metering for solar?
True retail-rate net metering is only available for legacy systems interconnected before December 31, 2019, and for some Entergy New Orleans customers. For new installations after 2019 in most utility territories, Louisiana uses net billing. Customers pay full retail rate for grid imports and receive avoided-cost credits for exports.
Is the federal solar tax credit still available in Louisiana in 2026?
No. The 30% federal Residential Clean Energy Credit under Internal Revenue Code Section 25D expired for homeowner-owned systems placed in service after December 31, 2025. Commercial, leased, and power-purchase-agreement systems may still qualify for Section 48E. Construction must generally begin before July 4, 2026, or the system must be placed in service by December 31, 2027.
How much does solar cost in Louisiana in 2026?
A typical residential solar system in Louisiana costs roughly $2.90 to $3.10 per watt before incentives. A 7 kW system runs about $20,300 to $21,700. Louisiana homes use more electricity than the national average, so system sizes tend to be larger.
What is the typical solar payback period in Louisiana?
Payback periods for cash-purchased residential solar in Louisiana typically range from 10 to 16 years in 2026 without the federal residential tax credit. Systems in Entergy New Orleans territory with full retail net metering can pay back closer to 8 to 10 years. Systems in areas with low avoided-cost export credits and no utility rebate may stretch to 14 to 18 years.
Does Louisiana have a state solar tax credit?
No. Louisiana previously offered a solar energy systems tax credit under La. Rev. Stat. § 47:6030, but it expired and is no longer available for new installations. The only surviving statewide tax benefit is the property tax exemption. Some websites still list the old credit, so verify current law before relying on it.
Will solar panels increase my property taxes in Louisiana?
No. Louisiana Revised Statute § 47:1706 exempts solar energy systems attached to owner-occupied residential buildings from ad valorem property taxation. The home itself can still appreciate, but the assessed value cannot include the solar equipment.
What is net billing in Louisiana?
Net billing is a billing arrangement where electricity you import from the grid is billed at the full retail rate. Excess solar electricity you export is credited at the utility’s avoided cost, which is much lower than the retail rate. In Louisiana, avoided-cost credits are typically 2.6 to 2.8 cents per kWh, while retail rates are 12 to 14 cents per kWh.
Are solar batteries worth it in Louisiana?
Batteries can make sense in Louisiana because avoided-cost export credits are low. Storing midday solar and using it in the evening displaces grid imports worth 12 to 14 cents per kWh. Batteries also provide backup power during hurricanes and tropical storms. However, they add $10,000 to $20,000 to the project cost and extend the payback period.
What financing options exist for solar in Louisiana?
Homeowners can pay cash, use a solar loan, lease the system, or sign a power purchase agreement. Cash purchases deliver the highest lifetime savings. Solar loans spread the cost over 10 to 25 years. Leases and PPAs require no upfront payment but usually produce lower total savings. The state’s Home Energy Loan Program concluded in December 2023 and is no longer accepting new applicants.
