Photovoltaic System Simulation Software:Solar Pro
Simulate electricty generation precisely with consideration for various elements of PV system and display the result comprehensibly.


Simulation including the shadow influence by surrounding buildings and objects allows users to check optimal settings and module designs before system installation.

I-V curve

The software calculates the I-V curve of solar modules accurately and quickly based on the electric characteristics of each manufacturer's product.

Electric power calculation

The software calculates the amount of generated electricity based on the latitudes, longitudes, and the weather conditions of the installation site. This leads precise simulation results.

support for designing

The software determines necessary component for installing PV system automatically based on the settings.

Upgrade Features of Solar Pro 4.8

Half-cell module compatible Supports power generation simulation using half-cell modules. In addition, half-cell solar cells can be registered in the solar cell module database.
Improved operability The PCS threshold setting can be saved by user setting, which saves time and labor to input when setting the electric circuit configuration.
Added solar radiation calculation function 3D CAD tab
Color-coded tiles for each solar radiation dose are displayed side by side on the plot site selected in 3D CAD window. You can display a legend list for the sunlight tile in a separate window. The results are printable.

Solar radiation graph tab
Displays a graph of the calculated average solar radiation amount and horizontal solar radiation amount corresponding to the subject site area. You can also display the amount of horizontal solar radiation as "No shadow". Graphs can be printed.

Form tab
Displays the form of the average solar radiation calculation result of the target site plotted in the graph. Forms can be printed and saved in CSV format.
