Despite similar irradiance and ambient conditions, differences in surrounding surfaces (grassy vs. concrete) led to notable variations in module temperature. Heavy snow fall events were identified as resulting in different power output behavior even in fields with the same geometric configuration. A custom power output model, accounting for tilt and temperature, flagged unexpected power output anomalies, leveraging a combination of partial on field irradiance measurements with online irradiance data. Results show that environmental factors do affect the power yield of solar fields in the same region, underscoring the value in further examining such factors to enhance the performance of solar installations in the future.en-USPrinceton University Senior Theses
