Automated PVsyst Correction Factor Generation in SunSolve Yield

Solomon Freer from PV Lighthouse demonstrates the new automated feature in SunSolve Yield that streamlines the generation of bifacial correction factors for view-factor programs like PVsyst. This update eliminates the need for manual repetition of multiple simulations, making the process much more efficient.

Key features covered:

• Automated calculation of rear shading, transmission, front and rear mismatch, and weighted albedo correction factors
• Simplified workflow that requires just selecting desired factors and hitting play
• Results formatted for direct application in PVsyst bifacial system settings
• Detailed analysis output with hourly correction factor data
• Comparison with previous manual process

The tutorial shows how to:

• Set up a bifacial system simulation with appropriate weather data and system parameters
• Configure lateral spacings for accurate transmission calculations
• Select and run automated correction factor analysis
• Apply the calculated factors directly in PVsyst’s bifacial system settings
• Download detailed results for further analysis

This automation significantly speeds up the workflow for bifacial solar system modeling, allowing engineers to quickly obtain accurate correction factors that improve the precision of view-factor based yield assessments. The approach is particularly valuable for standard bifacial systems, though more complex systems with multiple orientations may require more sophisticated modeling approaches or the use of the spreadsheet as detailed in this video.
