Abstract
Several recently published models of the direct component of the broadband insolation are compared for clear sky conditions. The comparison includes several simple models and one rigorous model that is used as a basis for determining accuracy. Two optimum simple models of varying degrees of complexity are developed as a result of this comparison.
