How Meteorological Inputs Contribute to Energy Modeling Uncertainty

It is well known that irradiance is the key driver of solar energy production. For this reason, lenders, independent engineers, and developers have emphasized global horizontal irradiation for energy production estimates. However, multiple meteorological parameters have a meaningful impact on energy. Diffuse irradiation, albedo, temperature, wind speed, precipitation, and humidity all impact system performance. These parameters should be considered for high-quality solar energy estimates. This presentation evaluates how secondary meteorological parameters impact energy production estimates. The analysis quantifies how energy production is sensitive to these input assumptions. Finally, the presentation shows how energy uncertainty can be reduced by giving appropriate attention to the most meaningful meteorological contributors to energy production. To facilitate engagement, the presentation will begin by asking several audience poll questions to calibrate the discussion to those present. The presentation will conclude with a question and answer session.
