Performance Services 12. Financial Guarantees a. Describe our alporoach to creatin and delivering on the savings guarantee. Performance Services intends to maximize the energy savings for your project primarily through careful consideration for the design of your solar facilities. We aim to deliver superior financial performance of your system/s by developing designs that balance upfront costs with efficient and effective power generation. Below is a list of just some of the items we evaluate to maximize value and energy savings for our customers: • Site location (distance to switchgear, shading, and topography considerations) • Panel selection (wattage, efficiency and cost considerations) • Inverter selection (size, stringing and cost considerations) • Panel angle (row spacing and production ratio considerations) • System commissioning for optimal performance • Holistic facility overview to evaluate the impact of mechanical and electrical kWh reduction to help "right -size" the solar design Performance Services uses International Performance Measurement and Verification Protocol (IPMVP) for all its guarantees. Unlike other providers that only use Option C, The Whole Facility Method, Performance Services utilizes methods designed specifically for the improvement item selected. For example, according to the IPMVP manual, Option A is most effective for lighting retrofits. Option B is used for replacement of equipment that utilizes electricity and Option C (Whole Building) is excellent for gas energy savings i.e. comparing gas bills of the base year to gas bills of the post -retrofit period. The selection of the most optimal and cost-effective methodology for performance assurance will depend on the improvements selected by the City of South Bend. As part of the contract development process, Performance Services will work with your city to specify the exact monitoring of program improvements for each improvement option. The sum of these will be used as the basis of the performance guarantee. For your project, we would recommend Option A which involves a one-time measurement of solar output. After the successful completion of the installation and commissioning phases of the project, Performance Assurance is the next vital step to ensure the project performs as expected. Our in-house Performance Assurance team professionally monitors the performance of the solar arrays for the 1st year after completion. This is critical to ensuring any operational issues that occur are discovered and resolved as quickly as possible. In addition, our Performance Assurance team can prepare a professional Annual Savings Report to document how the system has performed and how much energy savings have been achieved.
