Shadow Calculator -- a solar CAD tool for the design and shading calculations of solar energy systems with static solar collectors like plane panels of PV-modules on a roof or rows of inclined PV-modules on the ground. It includes the toolkit for the complete site analysis at any climatic conditions.


Use Shadow Calculator to implement the site analysis and optimization of your solar project:










If you have an interest in solar energy (as a user, investor, or professional designer/installer of solar collectors) and want firstly to know how Shadow Calculator can help you to error-proof, develop, and optimize your solar project, start your reading at once from the chapter Your Solar Project, and return later to a more regular reading of other chapters.


This is the screen shot of a typical session with Shadow Calculator. You see the 3D View window with the static collector system on the southern plane of the roof. This window is available also in Shadow Visualizer. You can use it for visual analysis of the shading of your collectors. You see also some "solar" windows that are available in Shadow Calculator and Shadow Analyzer only. Each "solar" window has a few pages that display different aspects of the corresponding information. The Climate & Irradiance window allows to set the climatic characteristics of your site. The Solar Day and Solar Year windows display the irradiation, shading, energy losses, and energy output of your system.





Shadow Calculator is an advanced parametric CAD tool for professionals in the area of Solar Energy Engineering and Architecture. Unlike most of other 3D tools, Shadow Calculator displays not only objects themselves, but also the shadows they cast. Moreover, it calculates and displays the key numerical characteristics of shadows and their impact on the productivity of PV-systems.


Shadow Calculator is an ideal tool for the analysis of the shadow effects of any new projects or in the case of in-place installation of solar energy equipment. It allows to analyze shadows from external objects as well as the self-shading of static solar collector systems during a day in several seasons of the year, on any geographical latitude. 


The parametric CAD features of Shadow Calculator allows you to compose scenes, populate them with objects, change object dimensions, location, orientation, colors, and reflectivities. You can also apply textures to objects' surfaces. After all these transformations, you can save scenes in (.sa1) files.


Shadow Calculator is a stand-alone tool. It does not depend on any other applications or any third-party packages.
