Diffuse solar irradiance estimation on building's façades: Review, classification and benchmarking of 30 models under all sky conditions

摘要: Abstract Solar energy potential analysis on oriented and tilted surfaces, such as building facades, is of capital importance to estimate the production in integrated systems, BIPVs. The spatial distribution solar diffuse outstands one most critical factors order improve performance simulations. Nevertheless, wide spread models have been only evaluated equator facing surfaces with daily mean or hourly time ranges. Thus, this paper, 30 transposition irradiance models, from semiphysical classical ones newest non-parametric are reviewed, classified according their characteristics against empirical 10-min averaged values gathered high precision pyranometers placed vertical positions four cardinal directions. Models’ by several statistical estimators a benchmark has carried out non-parametrical aggregating procedure. Results show that accurate appear be ones. From these, Multi-Layer Perceptron obtains best results. parametric whose estimations closest measures Perez et al. local optimized coefficients. model original coefficients, Skartveit Olseth Igawa also good performance.
