Laplace System's Solar Pro Software Integrates Bifacial Module Simulation, Enhancing PV System Design and Performance Analysis
Key Insights
Laplace System has updated its Solar Pro software to include advanced bifacial module simulation, reflecting the growing adoption of dual-sided PV technology.
The new version enhances accuracy with 3D environmental reflection modeling and supports module-level optimizers for improved energy yield calculations.
Reporting capabilities are expanded to include 15-minute and 30-minute intervals, providing more granular performance data for PV system analysis.
With over 3,700 installations globally, Solar Pro continues to be a leading tool for photovoltaic system design and economic feasibility assessment.
Laplace System Co., Ltd., a leading provider of renewable energy measurement and simulation technologies, has released a significant update to its widely adopted photovoltaic system design software, Solar Pro. The latest version introduces advanced bifacial module simulation capabilities, a critical enhancement responding to the rapidly increasing global deployment of dual-sided PV modules. This update, highly anticipated by the industry, aims to provide unparalleled accuracy in predicting energy yield and economic feasibility for complex solar installations.
Originally launched in 1997, Solar Pro has established itself as a high-precision tool for designing, analyzing, and evaluating PV systems, boasting over 3,700 installations worldwide as of March 2025. The software's new bifacial module simulation feature allows for precise modeling of power generation from both the front and rear sides of solar modules. This includes sophisticated 3D modeling of environmental reflections from the ground, walls, and nearby surfaces, enhancing the realism and accuracy of yield predictions. The system now supports up to two levels of specular reflection, further refining simulation fidelity.
Beyond bifacial capabilities, the update incorporates support for module-level optimizers, which are increasingly deployed to mitigate shading losses and maximize energy harvest. Solar Pro can now simulate the performance benefits of these optimizers, assuming one optimizer per 1-2 modules, providing a more comprehensive assessment of system performance. Additionally, the software's reporting functionality has been expanded to include 15-minute and 30-minute interval outputs, complementing the existing hourly data. This finer time resolution offers more granular insights into system performance, crucial for detailed operational analysis and grid integration studies.
Laplace System, celebrating its 35th anniversary in 2025, has been a pioneer in renewable energy solutions, particularly in photovoltaic power. The company reports deploying over 90,300 monitoring systems totaling 22.8 GW in capacity as of March 2025, positioning it as the market leader in Japan for PV system remote monitoring services, according to Fuji Keizai Co., Ltd. The continuous evolution of Solar Pro underscores Laplace System's commitment to driving innovation and supporting the global transition towards renewable energy through advanced technological solutions.
