Monthly-average daily utilizability, anti phi is defined to be the fraction of the total solar radiation incident on a surface which is above a specified critical level. The utilizability function provides a concise description of solar weather in a form useful for solar energy system design. Many passive systems are designed with an overhang to prevent excessive solar gains in summer months. A simple analytical method of estimating the monthly-average radiation on surfaces which are partially shaded by an overhang has been developed. This method is extended to develop a method of estimating the monthly-average daily utilizability on vertical, south-facing surfaces shaded by an overhang.
