Shading & Loss Analysis
Identifying Performance Losses in PV Systems
Photovoltaic systems are subject to a range of performance losses that can significantly affect energy production. Shading from terrain, surrounding objects or system components, as well as electrical and operational losses, can reduce overall system performance if not properly assessed during project design.
Accurate identification and quantification of these losses are essential to ensure realistic energy yield estimates and reliable project performance forecasts.
Voltares performs structured shading and loss analysis as part of the technical assessment of photovoltaic projects. Using detailed site data and system modelling, we identify potential shading effects and evaluate key performance losses affecting the system.
This analysis supports optimized system design, improves the reliability of production estimates and helps developers reduce performance risks during project development.
Tools
Assessment of shading impacts from terrain, nearby structures, vegetation or system components using spatial and system modelling tools.
Evaluation of surrounding terrain and potential obstacles affecting solar irradiation and system performance.
Analysis of performance losses including temperature effects, electrical losses, soiling, mismatch and system availability.
Identification of design adjustments to reduce shading impacts and improve overall system performance.
Evaluation of potential production risks related to shading and system losses to support reliable project planning and financing.
