Originally launched in 1997, Solar Pro is a high-precision software tool for designing, analyzing, and evaluating the performance and economic feasibility of photovoltaic systems. With over 3,700 installations worldwide (as of March 2025), the software has gained international recognition and was featured in the German PV industry magazine PHOTON in 2001. Three international versions of Solar Pro are currently available:
– English Edition: For overseas markets excluding Korea and Taiwan – Korean Edition: Korean language version including Korean meteorological data
– Taiwanese Edition: English version including Taiwan-specific meteorological data The latest version introduces a highly requested new feature—bifacial module simulation—developed in response to the growing adoption of bifacial PV modules capable of generating electricity from both the front and rear sides.
Key New Features ・Bifacial Module Simulation Simulates power generation from both sides of bifacial solar modules. Includes 3D modeling of environmental reflections from the ground, walls, and nearby surfaces for enhanced accuracy. ・Two levels of Reflection Modeling Supports up to two levels of mirror-like (specular) reflection from surfaces such as walls and the ground, further improving the realism of simulations. ・Optimizer Support
Enables simulation of module-level optimizers that enhance energy yield, assuming one optimizer per 1–2 modules. ・Additional Time Resolutions for Reports In addition to hourly outputs, the system now supports 15-minute and 30-minute interval reporting.
