The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

HB 705

Note: HB 705 of 2013 phases out this tax credit until its termination at the beginning of 2018 in addition to halting credits for wind energy systems and adding special provisions for leased systems. The Louisiana Department of Revenue (LDR) has developed rules to carry out mandates of the legislation available here.

Louisiana provides a tax credit for solar energy systems purchased and installed on or after January 1, 2008 and before January 1, 2018. The credit may be applied to personal, corporate or franchise taxes, depending on the entity which purchases and installs the system, but the system must be installed at a single-family residence to be eligible (systems installed at residential rental apartments were made ineligible by HB 705 of 2013). HB 858, enacted in July 2009, extended the tax credit to all taxpayers that purchase and install systems. (The credit was previously only available to residential property owners). Only one credit may be taken per system, so if the property is sold, the taxpayer who originally claimed the credit must disclose this, as the new owner will not be eligible for another tax credit on the same system. Each residence is limited to just one credit. A second system installed at the same residence is ineligible for a credit. The tax credit may be applied both to solar-electric systems (photovoltaic systems) and solar-thermal systems, when the energy is used for space heating, space cooling or water heating.

Customer Owned Systems

For systems purchased between Januay 1, 2014 and January 1, 2018, the credit is equal to 50% of the first $25,000 of the cost of each system, including installation costs. The credit must be fully claimed in the taxable year in which the system is installed and placed in service. Equipment added at a later date cannot utilize any existing system components in order to qualify for the tax credit. Any excess credit which exceeds the taxpayer's liabilities for that year shall be treated as an overpayment, and the DOR will issue a refund for the remaining amount within one year of receiving the claim.

For photovoltaic (PV) systems, the tax credit applies to AC or DC generation systems which are grid-connected, net-metered systems (with or without battery backup) and stand-alone systems. Solar-thermal systems must be used for the primary purpose of heating water, space heating or space cooling.

Electrical equipment must be tested and certified by a Federal Occupational Safety and Health Administration (OSHA) nationally recognized testing laboratory and installed in compliance with all applicable building and electrical codes. Solar thermal equipment must be certified to SRCC OG-300 by either SRCC or by listing agency such as International Association of Plumbing and Mechanical Officials (IAPMO) and installed in compliance with all applicable building and plumbing codes. Installations must be performed by a licensed contractor, the owner of the residence, or by a person who has received certification by a technical college in the installation of such systems. In order to claim a tax credit for a wind or solar energy system all components must be installed at the same time as the system.

This tax credit may be combined with any federal tax incentive, but it may not be combined with any other state tax incentive. Whenever additional incentives such as cash rebates, prizes or gift certificates are offered in addition to the tax credit, the eligible cost must be reduced by the value of the additional incentive received.

Leased Systems

Systems leased by a third party and used at a residence can qualify for a tax credit, but there are additional provisions in the law that apply to these systems. For leased systems that are installed after December 31, 2013, the value of the credit will be reduced to 38% of the first $25,000 of the cost of each system. Additionally, leased systems can be no larger than 6 kilowatts (kW). The law also sets maximum system costs for leased systems. A leased system can claim system costs that do not exceed these limits depending on the year it is placed in service:

  • Placed in service between 7/1/13 - 6/30/14: $4.50 per watt with $12,500 limit
  • Placed in service between 7/1/14 - 6/30/15: $3.50 per watt with $9,500 limit
  • Placed in service between 7/1/15 - 12/31/17: $2.00 per watt with $4,560 limit
