Update: The Louisiana Department of Revenue has cleared up information for the Solar air conditioning systems. You CANNOT receive a tax credit for a solar air conditioning system.You can review their bulletin here.
***WARNING!!! Beware of some air-conditioning companies claiming you can get a 50% tax credit on your air-conditioning system if they install some solar modules with it. A brand of air-conditioners offer a “solar” option which is nothing more than a small offset of the energy usage of the unit. You will not get the Louisiana tax credit on your air-conditioning system and they will probably be arrested for fraud if they are caught including the air-conditioner as part of the solar power system!
