Evaluation of 12 Transposition Models Using Observations of Solar Radiation and Power Generation

This article evaluates the performance of 12 solar transposition models according to the measured data in Zhangbei of Northern China, including four isotropic models, Liu&Jordan, Koronakis, Badescu, and Tian, and eight anisotropic models, Willmot, Bugler, Hay, Skartveit−Olseth, Stevenand−Unsworth, Reindl, Temps−Coulson, and Klucher. We measured global horizontal irradiance, beam global horizon...
