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 points of Solar Pro 4.5
Improved display speed The display speed is improved by reducing the load (hiding shadows and light
reflection)and improved processing of 3D CAD. Enabling and disabling of shadows and
light reflection can be changed using the check box, the result considers shadows and
light reflection even if it is disabled.
Adding slope object Users can add “slope” to the created objects. It is now possible to add complex terrain
with slopes, and the floor plan function makes it easier to place panels on slopes.
Expanded automatic layout function The number of placement restrictions when performing automatic or manual placement
on the floor plan input screen has been increased from 400 to 1,000.
In addition, the maximum number of placements can be set by the user, which allows
for smoother placement of module arrays.
Additional report output items Integrated reports will also show the array azimuth and tilt.
Since the set numerical values are entered automatically, it is reflected on the report.
