AMERESC04P <br />Green • Clean • Sustainable <br />ECM 7 — Install Solar PV <br />A ballasted roof mounted solar photovoltaic (PV) system was installed. The system includes ninety 260 <br />watt solar modules arranged in ten strings of nine panels each, racking (mounting), wiring, one 20 kW <br />inverter, grid connection and protection equipment, a data acquisition system, and a public display <br />showing current and historic production levels. <br />How Savings Were Determined — The savings for the Install Solar PV ECM were determined by modeling <br />the solar PV system using PVsyst, which is a third -party software package for the study, sizing, simulation, <br />and data analysis of complete PV systems. By providing the software with the required simulation <br />parameters, the expected system production is calculated. Simulation parameters include geographical <br />site information, meteorological data, panel plane orientation, module specifications, inverter <br />specifications, and array loss factors. The solar PV energy model, which includes the main results and <br />system loss diagram, can be referenced in Appendix C of the First Amendment to the ESA. <br />October 15th, 2024 <br />Page 20 <br />
