Radiactions
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.
The evaluation is made by:
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. Clicking on Run button the calculation it is performed and the map of radiations it is updated. |
