摘要：To define the diffuse radiation incident on an inclined plane of any orientation and of any tilt angle, we need to know sky diffuse radiation as well as ground-reflected radiation. Here we made a study of ground-reflected component of radiation on inclined surfaces with varying inclination angles for Lucknow (Latitude 26.750, Longitude 80.850), Mumbai (Latitude 19.120 N, Longitude 72.850 E), Calcutta (Latitude 22.650 N, Longitude 88.350 E), and Pune (Latitude 18.530 N, Longitude 73.910 E) cities of India using isotropic and anisotropic models. We have calculated the data for entire year using these models for all considered stations and obtained the percentage contributions in diffuse radiations. It is found that anisotropic model predict lower values than isotropic and contribution of ground-reflected component in diffuse radiation for isotropic model is more than anisotropic.
