Evaluation of Solar Irradiance Models for Hourly Irradiance Estimation on Vertical Surfaces in Vancouver, Canada: Comparison of 42 Models
Accurate estimation of hourly solar irradiance on building facades or on tilted surfaces of active solar systems, such as photovoltaic, is crucial for the design, site selection, and energy performance analysis of both buildings and various solar energy conversion systems. However, the absence of measured diffuse horizontal irradiance and global irradiance on inclined surfaces continues to pose a significant challenge when evaluating existing solar irradiance models for different locations. This study aims to assess the performance of various solar irradiance estimation models in estimating hourly solar irradiance on the southeast facade of a Building Envelope Test Facility in Vancouver, Canada. In this work, 42 solar irradiance estimation models that are created by combining seven global horizontal decomposition models (DMs) and six transposition models (TMs) are considered. The results indicated that the Hay, Perez, or Reindle models, in conjunction with the DISC model, yielded the most accurate estimations for the spring and summer seasons. However, an isotropic model, when paired with the Erbs, Boland, or ED decomposition model, showed superior performance during winter and fall.
