WHFRTC WF400 90KW AC PVWatts Calculator.pdf

This document is a photovoltaic system performance results report from the National Renewable Energy Laboratory (NREL) for a solar installation located in Greenville, Kentucky. The report provides a comprehensive analysis of a 105.3 kW DC solar system with a fixed (open rack) array, detailing monthly and annual energy production, solar radiation levels, and system specifications. The system is expected to generate 143,164 kWh per year, with monthly AC energy output ranging from 8,013 kWh in January to 15,528 kWh in June.

The PV system specifications include a 1.2 DC to AC size ratio, 96% inverter efficiency, and a 20-degree array tilt with a 180-degree azimuth. System losses are calculated at 14.08%, and the ground coverage ratio is 0.4. The monthly irradiance loss is consistently 0% across all months. The DC capacity factor is 15.5%, and the system uses standard modules mounted on a fixed open rack. The location's coordinates are latitude 37.21° N and longitude 87.18° W, with a weather data source providing solar radiation and energy production metrics for the site.
