Shadow Calculator is the advanced parametric CAD tool for static PV-systems

Shadow Calculator (for Windows 7 / 8 / 10)

Shadow Calculator vs. Shadow Analyzer ...

To choose the proper product for your typical solar projects note that Shadow Calculator works with static PV-systems only (plane panels of PV-modules on a roof or rows of inclined PV-modules on the ground), while Shadow Analyzer analyses also the sun-tracking PV-systems with panels of PV-modules installed on 1-axis and 2-axes trackers. So if your projects include trackers, you definitely need Shadow Analyzer.

With both the products you can create the 3D model of your project in the particular architectural environment of your site, and then visualize shadows on your solar collectors for different days and seasons. This visualization allows you quickly error-proof your project to make sure whether it is really free of shadows for the most daytime hours. Then you can copy 3D views of the project into other applications like MS Word or MS PowerPoint to write an illustrated report or to prepare an animated presentation for a lecture.

Both the products are also good marketing and presentation tools for the negotiations with clients. The "3D View" windows highly improve the impression from your project proposals, make them more consistent and clear for your clients, and assure your clients in the reliability of your project.

In addition to the simple visualisation, both products provide you with various forms of the graphical and numerical information about energy characteristics of each version of your project. They allow you to specify the climatic parameters of your site for energy calculations. The calculated characteristics of the shading, energy losses, and the energy output of your system are displayed in several "solar" windows for a particular day or the entire year.

You can briefly consider the graphical representation of the data (displayed as a set of curves of the calculated characteristics), or carefully investigate some details using the Table window that displays the numerical values in tables. Then you can transfer the tables into other applications like MS Excel to compare data of different versions of your project and implement further numerical analysis for the optimization of your project or for more specific research tasks.

Shortly speaking, use Shadow Calculator or Shadow Analyzer if you want to optimize your solar project in respect with shadows provided by the specific architecture environment of a particular site, or if you want to evaluate the average yearly productivity of the project under your climate conditions. Both products are especially useful for the optimization of static arrays of the inclined PV-modules, while Shadow Analyzer is especially useful for the optimization of the sun-tracking PV-systems, because in these cases the self-shading can play the major role.

Explore the solar energy potential of your site and optimize your solar project with our Shadow Calculator.
Analyze your particular site including its local architecture conditions and regional climate characteristics.

Shadow visualization is good but the complete site analysis is better. Our solar software Shadow Calculator includes all features of Shadow Visualizer and has much more options for the optimization of your solar project. It not only visualizes shadows on solar collectors, but it also measures their energy weights.

Shadow Analyzer expresses in graphs and tables the daily, monthly, and yearly profiles of many useful energy characteristics of the solar equipment from the daily energy losses associated with shading of individual solar panels to the annual energy yield of the entire solar installation. It provides you with the complete site analysis for your solar project including both the local architecture conditions of your particular site and the general climate conditions of your region.

Home users can easily estimate the solar energy potential of their roofs, walls, and any other free surfaces of their houses and gardens with Shadow Analyzer.

Professionals (solar engineers, architects, and installers of solar equipment)  can discover many hidden potential reserves to improve the annual productivity of solar PV-panels and solar thermal collectors under particular local conditions with Shadow Analyzer.

Whether you are a homeowner searching for the best orientation of a simple solar collector according to your local geographical latitude and seasonal variation of solar radiation at your particular site, or you are a solar engineer considering a sophisticated problem of the economically optimal configuration of the complex arrays of sun-tracking solar collectors for a large-scale solar PV power plant, Shadow Analyzer will help you to find the proper solution.

The "3D Communications" option of Shadow Calculator ...

As well as all our products, Shadow Calculator is also the tool for 3D communications. In 3D communications you send 3D scenes instead of a plane text or static pictures. Read the general discussion on 3D Communications on the page of 3D Message Free.

The scene files are amazingly small (only a few kilobytes). You can send them by email as a very light weight attachment.

This option is very convenient for solar professionals communicating with their permanent partners: the designers and planners of solar energy systems, suppliers and installers of the solar equipment, etc.

Your recipients do not need to buy any product to read your 3D messages -- they can either use the time-unlimited Trial version of Shadow Calculator to view your scenes with shadow effects, or use 3D Message Free to edit your scenes and send them back to you for further discussions.

The user interfaces of Shadow Calculator and Shadow Analyzer are the same ...

The user interface of Shadow Calculator is very friendly and intuitive. In a few minutes, you can compose a scene, populate it with objects, change object dimensions, location, orientation, colors, and reflectivity. After all these transformations, you can save the scene in a file.

The user interface of Shadow Analyzer
The user interface of Shadow Calculator / Analyzer is shown without the '3D View' and 'solar' widows to simplify the picture.

Read the general discussion on the User interface of the scene management and the description of main toolbars on the page of 3D Message Free.

With Shadow Calculator / Analyzer, you can also apply textures to objects' surfaces. For this purpose, the user interface of Shadow Calculator / Analyzer has the toolbar Textures. The combination of textures and shadows provides the excellent visual effect for the presentation of your solar project.

The three-steps way to the practical usage of our software is:

Read the documentation ...

The documentation is written as a step-by-step tutorial with multiple illustrations, and you can read it consecutively as an entire book. First chapters describe the common features of all products. Next chapters describe more advanced products.

If you prefer to read the illustrated description before to try the software, than ...

You can read also its online version, using the following link: "Online Help".

And yet, you can read its shortest version in our online "Tutorial" that explains the key points of the user interface and the idea of the scene management by means of parametric objects.

Try before to buy ...

In the Trial version, you can try the user interface and product options, you can train yourself in how to compose new scenes, but you cannot save scenes in files (instead, you can consider multiple pre-created example scenes).

Shortly speaking, use 3D Message Free if you want to create your own scenes and save them in the scene files, use the Trial versions of products and consider the included example scenes if you want to know what you can do with our software.
