The Cost of Solar Panels in Louisiana (2025 Guide)

With abundant sunshine and the ever-present need for reliable power during hurricane season, installing solar panels is one of the most effective ways for Louisianans to take control of their energy costs and achieve true energy independence.

What’s Included in Your Solar System Price?

The price of a solar system is an all-inclusive investment in your home’s energy future. Here’s a clear breakdown of what you’re paying for:

• Solar Panels: High-efficiency photovoltaic (PV) modules that capture Louisiana’s ample sunlight.
• Inverter(s): The essential device that converts solar energy into usable electricity for your home.
• Racking and Mounting: Durable, hurricane-rated hardware that securely attaches the panels to your roof.
• Professional Installation: The crucial work done by certified electricians and installers to ensure your system is designed for maximum production and installed to the highest safety standards.
• System Design and Engineering: The expert work to create a custom solar blueprint tailored to your home’s specific energy needs and roof layout.
• Permitting and Inspection Fees: The administrative costs required by your local municipality and utility company (like Entergy).

Cost of Solar Panels in Louisiana by Home Size

Your final cost is directly related to your home’s size and your monthly electricity bill. A larger home that uses more power will need more solar panels, increasing the total cost. The table below provides a general estimate of what you might expect.

Home Size	Avg. Monthly Bill	Est. System Size	Cost Before Incentives
1,500 sq. ft.	$120 – $170	7 – 9 kW	$15,400 – $22,500
2,000 sq. ft.	$170 – $220	9 – 11 kW	$22,500 – $27,500

3,000+ sq. ft.	$270+	13 – 15 kW+	$32,500 – $37,500+

How Incentives Reduce Your Solar Cost in Louisiana

While the gross cost is an important starting point, powerful financial incentives are in place to make solar more affordable. The 30% federal tax credit is the most significant program available to every Louisiana homeowner, capable of reducing your total cost by thousands. The state also offers a valuable property tax exemption to ensure your investment doesn’t increase your tax burden.

Name of Incentive	Type	Benefit for Homeowner	Average Value
Federal Solar Tax Credit	Federal Tax Credit	Claim 30% of your total system cost on your federal taxes.	$4,500 – $8,100
Property Tax Exemption	State Tax Exemption	Your property taxes will not increase due to the value added by your solar system.	Varies
Net Metering	Utility Bill Credit	Earn credits on your utility bill for excess electricity your system sends to the grid.	Varies
