About this file
This document contains solar system performance reports prepared by the Pennsylvania Solar Center using Aurora Solar simulation software for multiple solar photovoltaic projects identified by the Sustainable Energy Partnership (SEP), a consortium comprising Bucks County, Chester County, Delaware County, and Montgomery County in Pennsylvania. The reports present detailed technical analyses and annual energy production projections for eight distinct solar installations across the Montgomery County region, including systems at the Fire Academy (540 Port Indian Rd, Eagleville, PA), Youth Center (60 Eagleville Rd, Eagleville, PA), Trail Center (75 East Lafayette St., Norristown, PA), and Courthouse Annex (102 N York Rd, Willow Grove, PA). Each project includes comparative analyses between two system configurations: one utilizing Enphase microinverters and one utilizing SolarEdge string inverters with power optimizers. The projects range in scale from 22.82 kW to 1.78 MW DC nameplate capacity, with annual production estimates ranging from approximately 29.3 MWh to 2.375 GWh. The simulation reports employ standardized weather data from the National Renewable Energy Laboratory (NREL) for the region at coordinates 40.15, -75.35, with consistent assumptions regarding soiling rates, albedo, module characteristics, and system losses applied across all analyses.
The reports detail comprehensive system metrics including performance ratios ranging from 75.8 percent to 84.6 percent, module specifications utilizing QCELLS Q.PEAK DUO bifacial solar modules rated at 485 watts or 585 watts, and inverter options from Enphase and SolarEdge manufacturers. Each analysis quantifies system losses across multiple categories including front shading (1.0 to 5.4 percent), reflection (3.0 to 3.6 percent), soiling (4.9 to 5.2 percent), temperature derating (2.0 to 6.8 percent), and inverter losses (1.5 to 3.5 percent). The documents provide detailed field segment layouts specifying racking configurations, tilt angles, azimuth orientations, module counts, and power ratings for each installation. All simulations were conducted using identical meteorological conditions and thermal modeling parameters, establishing a standardized baseline for comparing system performance between different inverter architectures and configurations across the SEP counties' solar procurement initiative.
