Abstract: A survey has been made to investigate the characteristics of solar radiation in Hawaii. Solar radiation data for over 60 monitoring stations have been examined, and they are generally located in the low elevation plain areas. Correlation study indicated that median annual rainfall intensity is related closely to mean annual insolation levels. However, rainfall is not a good indicator for direct forecast of insolation. The model of clear sky insolation on horizontal surface has been studied. A Fortran computer program has been written for simulation of clear sky insolation. The similarity between the diurnal insolation patterns and the clear sky patterns indicates that the clear day model may be used to estimate the actual insolation. For estimating the long term mean annual insolation, a model is proposed to compare one year of data at any site to a currently existing monitoring station. The mean monthly insolation of a station may be estimated if the mean annual insolation of that station is known.
