So, three anisotropic and equal quantities of isotropic models were engaged regularly in New Delhi and their outcomes were analyzed for choice of correct and fitting model for this territory. Three isotropic models to be specific BA (2002), LJ (1960) and KO (1986) and three anisotropic models to be specific HDKR (2006), HD (1980) and RE (1990) model were explored. Here tilt angle was adjusted at 28.58° N (New Delhi latitude). The result of six models had been compared with ground measured data. For this five statistical tests are used for comparison. HD evaluated the most noteworthy measure of occurrence sun oriented radiation in the entire year while BA set up the least among entire models. LJ and KO model showed similar outcomes. The outcomes of statistical analysis gave that HDKR provided smaller MAPE (1.02%), MBE (0.129 kWh/m2-day), RMSE (0.605 kWh/m2-day), RMSRE (0.393 kWh/m2-day) and RRMSE (1.858%) among all six models. Ultimately, HDKR model was favored for estimation of sunlight based radiation occurrence on an inclined plane with least errors. MATLAB has been used for implementation.
