Large Solar Water Heating Systems (OG-100 Rated) - Up Front Incentives

Up-Front Incentives (UFIs) for new large solar water heating systems for non-residential customers are available on a competitive basis up to a maximum incentive equal to $0.41 times the estimated first year kWh savings the system provides. The kWh savings estimate is based on an Energy Savings and Design (ES&D) report) supplied by the customer or installer. The ES&D report must be stamped by a Professional Engineer (PE) and will be verified by APS. The collectors used in the system must also have an industry "OG-100" performance rating as published by the Solar Rating and Certification Corporation (SRCC). UFIs are also limited to $75,000 and cannot cover more than 50 percent of the cost of your system.

Funding for up-front incentives is awarded on a competitive basis every other month. At the end of each bi-monthly period, renewable energy projects are compared to each other based on the “ranking score” each project receives from the APS UFI Ranking Calculator.

The score given to a solar water heating project is largely based on the amount of incentive that is requested for each kWh your system is estimated to displace during its first year of operation. The maximum incentives per kWh available under the program vary by technology and are listed on the APS Incentive Chart. When applying for an incentive, you may request the maximum incentive per kWh available, however, projects requesting less incentive per kWh will generally receive a more competitive score. Available funding for up-front incentives will be equally divided into the six bi-monthly allocation periods as noted below. Applications are due the last day of the respective period.

• January and February
• March and April
• May and June
• July and August
• September and October
• November and December

In most cases your installer will be familiar with the incentive process and can help you with any of the required forms.

Before you apply:

• Review the decision process to see how APS determines if your request for funding is approved and when you can expect to receive a funding decision.
   
• View a working model of the UFI Ranking Calculator (MS Excel) so that you have an understanding of how your project will be scored.
   
• Refer to the Equipment Qualifications and Installation Guidance information sheet for specific information regarding equipment and installation requirements that must be met to qualify for an incentive.
   
• Review the Non-residential Incentive Timeline for information on the process flow and corresponding milestones which will help you stay on track to receive your incentive. Systems receiving an up-front incentive must be installed within 180 days of receiving funding notification from APS. Missing this or other project completion milestones may result in funding being cancelled for you project.

Steps in the incentive process.

1. Submit a completed and signed reservation application which includes:
   
   
   • A system description and itemized quote for all system and installation costs. The quote must include the manufacturer and model number of the OG-100 rated solar collectors.
   • Your UFI Ranking score which includes your initial estimate of kWh savings the system will provide.
   • A copy of the signed installation contract between you and your chosen installer (the contract can be contingent on receiving APS funding). Applications that are submitted without a signed installer contract will not be accepted.
      
2. Approximately two weeks after the nomination period has ended, the cutoff score for that period will be posted on aps.com/GoSolar and projects receiving a funding reservation will be notified. If accepted, APS will send you a Credit Purchase Agreement (CPA) which you must review, sign and within 45 days. The CPA is the document that spells out the obligations between you and APS regarding the renewable energy credits (RECs) associated with the production from your system and must be signed in order to participate in the program.
    
3. Submit a completed ES&D report, stamped by a professional engineer, showing the estimated kWh savings your system will provide. Once approved by APS, the ES&D report will be used to calculate the actual incentive for which you qualify.
   
   
4. Obtain any local permits and proceed with installation of your system.
   After installation, obtain necessary municipal clearances ("green tag"). Typically your installer will assist you in obtaining permits and clearance.
   
   
5. Request your incentive payment from APS.
   Your request for payment should include:
   
   • Proof of final clearance from your local jurisdiction.
   • An Installation & Commissioning Certification form signed by both your equipment dealer and installer
   • A copy of the paid invoice(s) confirming the system purchase price, payment and installation by an Arizona licensed contractor.
