Attachment C <br />City of Roseville <br />PROPOSAL FOR 374.74 kW SOLAR ENERGY FACILITY <br />Design, Engineering and Permitting <br />A. Timeline and Schedule <br />Sundial proposes the following milestone schedule for Design, Engineering and Permitting of <br />this project: <br />Contract execution with City <br />09.01.15 <br />Engineering and design completed <br />10.01.15 <br />Permitting and environmental review <br />11.01.15 <br />Interconnection analysis and design <br />12.01.15 <br />Procurement Initiation <br />03.01.16 <br />Assembly and construction start* <br />04.01.16 <br />Assembly and construction complete* <br />06.01.16 <br />Testing and commissioning <br />06.01.16 <br />Commercial operation <br />06.15.16 <br />*Subject to weather conditions <br />B. System Description <br />Sundial recommends installation of 914 of the tenKsolar 410 -watt RAIS WAVE XT panels <br />manufactured in Bloomington, MN or a Tier 1 PV panel system with a total DC -rated capacity of <br />374.74 kilowatts. The tenKsolar equipment package comes with an integrated system of <br />inverters and racking. Sundial's proposal includes all required "balance of system" equipment <br />for interconnection to the electrical grid and a web -based monitoring system. Subject to further <br />discussions with the City and due diligence by Sundial, we are willing to negotiate use of <br />tenKsolar or a comparable Tier 1 solar equipment package for this project. <br />C. Equipment Details <br />The tenKsolar RAIS WAVE system offers one of the industry's best DC -to -AC efficiency ratios. A <br />reference tenKsolar ground -mount system tested at the National Renewable Energy <br />Laboratories (NREL) facility in Golden, Colorado in April 2012 found an efficiency ratio of 97.2 <br />percent, which compared with a conventional reference system at 89.3 percent. The <br />technology's elimination of single -cell dependence minimizes losses from non-uniform soiling <br />and snow loads. Overall, the technology has a module efficiency of 15.14 percent with a <br />performance ratio (kWh -received -to -kWh -produced) of 82.82 percent. <br />On this basis, the proposed system of 914, 410 -watt tenKsolar Titan panels with a total DC <br />capacity of 374.74 kW will produce a minimum of 470,000 kilowatt-hours of AC power in Year 1, <br />with annual degradation of 0.3% annually thereafter. Sundial will guarantee 98 percent of this <br />power output to the City, subject to adjustment for Typical Meteorological Year (TMY) data. <br />
