Estimation of global solar radiation on inclined surfaces

Generally, in the weather stations, the global solar radiation is measured on horizontal surfaces. However, to maximize the amount of solar radiation incident on the collector surface, stationary solar convention systems, both solar photovoltaic and flat plat solar collectors, are mounted on incline...
