Summary

Calculates the incoming solar insolation for input points or polygon features relative to the surface (ground) on Earth or the Moon.

The input features can represent locations or engineered surfaces by specifying attributes to define size, height, and orientation for analysis relative to the ground. Solar insolation is calculated as the amount of solar radiation energy received during an amount of time for each feature. Values are represented as totals and averages for the area of the feature and have units, kilowatt hours (kWh) and kilowatt hours per square meter (kWh/m2), respectively.

Usage

  • The defined spatial reference of the Input surface raster parameter specifies whether the analysis will be for Earth or the Moon.

  • The solar radiation computation requires the Output Coordinate System environment value to be in a projected coordinate system (PCS). It is recommended that the data be in a PCS with units of meters. If you run the analysis with a spherical coordinate system, you must set the Output Coordinate System environment to a valid PCS.

  • The input features must be point or polygon feature data. Analysis on 3D or multipatch are not supported.

    You can include additional details to represent engineered surfaces using the input feature parameters by specifying direction, tilt, area, and offset for all or individual features, for example, to represent a set of points as solar panel arrays on the ground or building rooftop.

  • It is recommended that you specify the output table format as geodatabase. This allows for increased performance and greater functionality. Tables in dBase file format (.dbf) have known limitations in precision, field name lengths, and date and time formatting.

  • The calculated solar insolation values for total, direct, diffuse, and direct duration are added as attributes to the output table. These include values for total insolation (across the entire area) and average insolation (per unit area) of each feature. The units are kilowatt hours (kWh) and kilowatt hours per meter squared (kwh/m2), respectively. Duration units are hours.

  • The total insolation is calculated by analyzing each cell location of the input surface raster that intersects the feature (or part thereof) and multiplying it by that feature's area. It is not calculated for a single central location of the feature.

  • If you are running an analysis for large extents with few or highly dispersed polygon features, the process may take additional time due to the resolution required for rasterization.

  • The Feature Slope, Feature Aspect, Feature Area, and Feature Offset parameters can be used to provide additional details to represent engineered surfaces that may intercept the incoming solar radiation, such as direction, tilt, area, and offset. These may be static or changing position and orientation in time. For example, a set of points that represent solar panel arrays on the ground or building rooftop, or a panel on a moving vehicle.

    If the feature parameters are not specified, the values are calculated from the input surface raster or the individual features by default. Points have an area of zero unless otherwise specified.

    If you provide a value for any of these parameters, it will be applied to all input features. Alternatively, you can provide an input field attribute from the input features to analyze each feature individually. If a field is specified and a value is missing (Null), the value will be set as zero.

  • Daylight saving time is supported for Earth only. For the Moon, times must be specified in UTC.

  • The End date and time parameter value must be equal to or greater than the start date. The total span of time must not be greater than one year. The start and end date times can cross the calendar year.

  • Output radiation values will be calculated for each respective time interval. If no solar radiation was received for a time interval, the result for that location will have a value of zero.

    If the total time specified between the start and end times is not equally divisible by the time interval, the total duration will be extended internally to provide the required number of time slices. For example, if the Time Interval parameter is set to cover three days but the difference between the specified start and end times covers eight days, the time interval will be extended to nine days. No partial results for times will be returned.

  • The minimum time interval for Earth data is 30 minutes and must be proportional to 30. The minimum time interval for Moon data is two hours and must be proportional to 2.

  • The Neighborhood Distance (neighborhood_distance in Python) parameter determines the neighborhood size and calculates the surface parameter over this distance from the target cell center. The value cannot be less than the input raster cell size.

    A small neighborhood distance captures more local variability in the landscape, such as characteristics of smaller landscape features. With high-resolution elevation data, larger distances may be more appropriate.

  • If the Use adaptive neighborhood parameter is checked (use_adaptive_neighborhood = "ADAPTIVE_NEIGHBORHOOD" in Python), the neighborhood distance will change with variability in the terrain. The neighborhood distance will shrink if there is too much variability in the calculation window.

  • Earth's Moon does not have an atmosphere; the radiation parameters diffuse proportion and transmittivity are not relevant during analysis. As a result, the incoming diffuse solar radiation is zero and the total radiation is equal to direct solar radiation.

  • The diffuse proportion is the fraction of global normal radiation flux that is diffuse. Values range from 0 to 1. Set this value according to atmospheric conditions. Typical values are 0.2 for very clear sky conditions and 0.3 for generally clear sky conditions.

  • Transmittivity is the ratio of the energy reaching Earth's surface to that which is received at the upper limit of the atmosphere. Values range from 0 (no transmission) to 1 (complete transmission). Typically observed values are 0.6 or 0.7 for very clear sky conditions and 0.5 for a generally clear sky.

  • Transmittivity has an inverse relationship with the diffuse proportion parameter. Altering these values may affect the model result. Identifying the best values for the area of interest depends on several variables (such as location and time). You can change these values to compare how they affect the result.

  • The Sun Map Grid Level parameter controls the speed and accuracy of the computation. It adjusts the resolution of the hexagonal grid cells that will be used for the internal calculations, based on the H3 geospatial indexing system.

    A lower grid level creates fewer larger sun map areas and decreases tool run time. A higher grid level creates more smaller sun maps, improving the accuracy of the result.

    Valid values of the sun map grid level for Earth range from 5 to 7. For the Moon, the valid value range is from 4 to 6.

    The default level is determined by the input surface raster. When analyzing surface data on Earth, if the analysis cell size is less than or equal to 4 meters, the default grid level is 6. If the cell size is greater than 4 meters, the default grid level is 5. For analyzing surface data on the Moon, the default level is 6.

    The following table shows the average area of the hexagon grid cells for each sun map level, in units of square kilometers:

  • GPU only—The calculation will only be performed on the GPU.
String
Output Join Layer
(Optional)

The output layer that will be created by joining the output table to the input feature class. This is an optional output.

Feature Layer
Sun Map Grid Level
(Optional)

The resolution that will be used to generate the H3 hexagonal grid cells used for internal calculations. A lower grid level value creates fewer, larger sun map areas and decreases tool run time. A higher grid level creates more smaller sun maps improving the accuracy of the result.

Valid values of the sun map grid level for Earth range from 5 to 7. For the Moon, the valid value range is from 4 to 6.

By default, the grid level is determined by the input surface raster. When analyzing surface data on Earth, if the analysis cell size is less than or equal to 4 meters, the default grid level is 6. If the analysis cell size is greater than 4 meters, the default grid level is 5. For analyzing surface data on the Moon, the default grid level is 6.

The output layer that will be created by joining the output table to the input feature class. This is an optional output.

Feature Layer
sunmap_grid_level
(Optional)

The resolution that will be used to generate the H3 hexagonal grid cells used for internal calculations. A lower grid level value creates fewer, larger sun map areas and decreases tool run time. A higher grid level creates more smaller sun maps improving the accuracy of the result.

Valid values of the sun map grid level for Earth range from 5 to 7. For the Moon, the valid value range is from 4 to 6.

By default, the grid level is determined by the input surface raster. When analyzing surface data on Earth, if the analysis cell size is less than or equal to 4 meters, the default grid level is 6. If the analysis cell size is greater than 4 meters, the default grid level is 5. For analyzing surface data on the Moon, the default grid level is 6.
