ABSTRACT:
The only readily available solar radiation data for the US consists of measurements of total radiation on a horizontal surface. A knowledge of the direct component is needed to estimate the solar energy available for focusing collectors or tilted flat-plate collectors. A review of some of

the existing formulas for direct normal radiation is given. A study of the relationship between direct normal radiation and percent of possible was conducted using three special data samples. Finally, several more techniques for estimating direct normal radiation are presented. Show Less
