• All equipment installations are subject to verification inspection by the program to ensure the equipment is properly installed and operating. Participants must allow, if requested, the program or a program representative reasonable access to their home or business to verify the installed equipment.
• For specific equipment eligibility, please visit the "Equipment Eligibility" tab of this page.
• The system is purchased new. Resale equipment, new parts installed in existing equipment, or equipment that is leased, rebuilt, rented, received from insurance claims, received from a warranty, received from a grant, or won as a prize do not qualify.
• Equipment is installed by a professional contractor with a valid Wisconsin State professional contractor’s license, appropriate insurance, and permits.
• Equipment is installed conforming to all applicable building, local, state and federal codes, standards, ordinances and regulations, and manufacturer specifications.
• The system is installed in a property owned by the applicant, or the applicant has received permission from the property owner to install the equipment. If you do not own the property where this equipment is installed, as a residing tenant you are responsible for obtaining the owner’s permission to install the equipment for which you are applying for an incentive. Your submission of this application indicates that you have obtained this permission.
• All necessary utility service improvement costs are the responsibility of the customer.
• All necessary service improvement costs, including transformers and service lines, are the responsibility of the customer.

• System must be installed in conformity with the manufacturer’s specifications and all applicable codes and standards.
• System owners and installers must obtain all required permits.
• If the project site is serviced by a participating Focus on Energy utility and uses a non-residential rate, the project site does not have to be owned by the applicant. The project/system equipment, however, must be owned by the applicant in order to qualify and confirmation of this ownership should be provided. System ownership must revert to the property owner after a specified period of time, not to exceed 25 years.
• In order to receive a commercial incentive, the system must be connected through a non-residential rate meter.
• Allow approximately 8-10 weeks for your completed application to be processed. Incomplete applications cannot be processed. Failure to complete the application in full and provide the required supporting documentation will either delay the payment process or result in your application being denied. Receipt of an application does not guarantee payment of an incentive.
• Focus on Energy will only pay one incentive for each piece of equipment. Incentives paid on this application cannot be claimed on another Focus on Energy application. Similarly, incentives can only be paid to one person or entity (i.e., either the resident or landlord, not both).
