Description: Estimated Daily Solar Insulation Contours, in calories/ Source: State Dept. of Planning and Economic Development, Energy Division "Sunshine Maps." These maps are based on extrapolation of a limited number of data points and should be used as a general first-cut illustration of irradiance. They were originally intended to simply distinguish between "sunny" areas and "cloudy" areas. The sunshine maps should not be used for sizing PV arrays; map users are advised to seek additional data on sun-hours per day. The boundaries depicted in these maps are approximate only. Note: Apr 2024 - Hawaii Statewide GIS Program staff removed extraneous fields that had been added as part of 2016 GIS database conversion and were no longer needed.
