Performance <br />Services <br />our solar designs due to the purity of silicon used in their modules and quality control procedures. Panel <br />degradation of Jinko modules is far less than average. <br />Product warranty is important with any asset, especially when assets have 40 plus year life spans. All solar <br />panels come with a 25-year power production warranty. Solar racking also carries a 25-year warranty, <br />and inverters vary between 12- and 25-year warranties. Top manufacturers and proper engineering are <br />essential for long-term production and system efficiency. These best practices assure Performance <br />Services' customers the most value while maintaining a system through the first twenty years of <br />Guaranteed Energy Saving Projects. <br />Performance Services developed the K-12 school market in the suburbs of Chicago, cutting our teeth in <br />rooftop solar over the last three years. With over 6MW of rooftop solar, no other ESCO has more public <br />sector roof installations in the Midwest. Regardless of solar system size, our owners receive the same <br />solar product/component pricing because we are able to pass along the volume pricing discounts we <br />receive based on the amount of solar product we purchase across nine states and their respective <br />projects. Therefore, the material pricing for projects in this range would be the same as those installing a <br />MW worth of solar. The only fluctuation would be based on installation labor and will increase with <br />smaller system sizes. Based on this, there will be a range in costs for systems in the 75-200kW sizes. <br />Through our competitive bidding process, we will receive two to three installation quotes per project and <br />trade. If selected, our team will competitively bid and then review all costs with you so you can help make <br />the correct decision for the City of South Bend. Additionally, as discussed in previous sections, we will <br />solicit quotes from your local contractors and businesses we know to offer you the balance between <br />quality, local contractors, and a fair price. We will work with you on the local contractor list as well to <br />make sure there are no conflicts of interest. Structural and roofing considerations can also cause the cost <br />to fluctuate. Turnkey rooftop solar pricing in the size being considered will typically range from <br />$1.50/Watt to just under $2.00/Watt with the higher pricing for smaller more complicated systems. <br />Confidential & Proprietary Document 10.
