SOLAR CANOPY Basis of Design - Questions 91 and 92.pdf

This document is a Solar Canopy Basis of Design report for the Buffalo VA Medical Center, detailing a 946.4 kW solar photovoltaic (PV) system design. The system features 1,604 Talesun TD7G78M 590W solar panels, 6 Chint CPS SCA125KTL-DO/US-600 inverters, and is configured as a carport-mounted installation with a landscape horizontal orientation and 3-degree tilt. The annual energy production is projected at 1,127 GWh, with a performance ratio of 85.9% and an estimated annual energy consumption of 1,800,000 kWh.

The technical specifications include a solar PV system rating of 946,360 W-DC and 750,000 W-AC, utilizing a fixed tilt mounting system with backtracking enabled. The system's monthly production varies throughout the year, with peak generation in May and June, and lower output in winter months. The design accounts for various system loss factors, including reflection (4.1%), soiling (3.0%), and mismatch (3.7%), with an average operating ambient temperature of 11.5°C and an average cell temperature of 17.9°C.
