An investigation on diffuse solar radiation for 23 stations of India is carried out exploiting the 15years (1986 …–2000) recorded data. Seven generalized empirical models are developed correlating the diffuse radiation with the sunshine duration … most suitable equation. The study finds that a correlation of diffuse transmittance with percent sunshine, temperature and …

The study introduces a new regression model developed to estimate the hourly values of diffuse solar radiation at the … surface. The model is based on the clearness index and diffuse fraction relationship, and includes the effects of cloud … capable of predicting hourly values of diffuse solar radiation better than the previously developed ones (R2=0.93 and RMSE=0 …
