The global radiation at the solar noon on a summer solstice in Albuquerque, New Mexico (latitude 35° N) is 60mw/cm^2. Assume that (a) 30 % of this irradiance is diffuse radiation and (b) the ground surrounding a PV module is non-reflecting and (c) the diffuse radiation is uniformly distributed across the sky. Estimate the irradiance on the PV module (flat surface) facing south at 45° to the horizontal
