The calculation of the radiation distribution allows for an
evaluation, on the areas in the layout
of the PV system, of how the radiation of the sun is lost due to the
presence of near obstacles. The areas will be colored differently
depending on irradiance received throughout the year. The areas that
receive always the irradiation will be red while those who are always
in a shaded area of the obstacles will be colored blue.
The assessment of irradiation will be made only on the areas that are
enabled to the arrangement of modules.
This context it is available only in 3D

The evaluation is made by:
Irradiance on areas, global
irradiation received on the area, expressed in kWh/m²
Shading frequency distribution,
frequency with which the area is in the shade, expressed as a
percentage. 100% indicates that the area is always in the shade, the
0% that the area has always irradiated.

The command Radiation distribution opens
a windows to manage options involved in the calculation of the
irradiations on areas.
The track-control Calculation precision
improves the accuracy with which you calculate the distribution of
radiation near areas, the program thickens the mesh of points on
which you want to calculate the radiation. Increase the accuracy of
calculation can require more time of computation.
It is possible decide to apply the calculation on a specific period
of the year with settings Start date
and End date or over All
year.
With Advanced options it is possible to apply an algorithm of Mesh
refinement for calculation, in this way the software generate
a non uniform mesh for the definition of points of radiation
evaluation, but it will make more refined mesh in areas in which the
variations of radiation due to shades are larger.
This allows to obtain a calculation with less point of evaluation,
but better distributed. With Number
of steps of mesh refinement you can improve the result
precision.This options it is strongly recommended expecially for
large area with shades limited only in a little area.
