Louisiana Solar Information

Louisiana isn’t a bad state for solar. There’s always enough sunshine to cover your basic energy needs or at least to reduce your monthly electricity bill. The 26% Federal Solar Tax Credit as well as some local incentives will make your solar installation even more profitable.

Solar power in Louisiana is ranked 34th for installed solar PV capacity as of 2017 by the Solar Energy Industry Association. The state's "solar friendliness" according to Solar Power Rocks has fallen to 50th place for 2018 as the state credit program ends and other policy factors hamper market development. Taxpayers still benefit from federal incentive programs such as the 30 percent tax credit, which applies to business and residential solar photovoltaic and thermal energy systems of any size.

From January 1, 2008 to June 19, 2015, Louisiana offered a 50 per cent tax credit up to $12,500 for the installation of solar system for purchased systems, as well as a smaller credit for leased solar systems, which increased the affordability of solar PV and water heating. The state's legislature abruptly ended the credit program without providing full funding for eligible claimants, and a multi-year effort to resolve the funding shortfall ended successfully with signed legislation in 2017.

Google's Project Sunroof estimates Louisiana to have over 20GW of rooftop solar potential, of which New Orleans is estimated to have over 90% of its roofs capable of solar energy production.

Solar Panels on Mall of Louisiana

New Orleans' largest solar array is the 1MW array installed by Blattner Energy at the Entergy Patterson facility in New Orleans East. The largest solar project in the state of Louisiana is currently the 1.2MW rooftop solar system at the Mall of Louisiana, completed in 2017 by Solar Alternatives and Strata Solar.

According to Los Angeles Dept of Water & Power, we received the cost of kWH in your area and calculated energy consumption based on an average electricity bill for 3 months.
I am claiming the 26% Federal Tax Credit (ends 2020) i

When you install your solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is being phased out by 2022.

Most people are eligible to claim this credit (you must owe federal taxes to be eligible).
