Structural Calculation in Solar Projects: Wind and Snow Load Analysis
A solar energy system isn't just about panels and inverters. The mounting system (construction) that holds panels on roofs or ground is just as important as the panels themselves. Systems installed without structural calculations can be damaged under wind or snow loads.
Which Loads Must Be Calculated?
- Wind load: Suction and pressure forces acting on panels based on regional wind speed
- Snow load: Weight on the structure based on regional snow load value
- Dead load: Total weight of panels, rails, clamps, and connecting elements
- Seismic effect: Structural strength requirements in seismic zones
Engineering Standards
In Turkey, structural calculations must comply with TS EN 1991 (loads), TS EN 1993 (steel structures), and TBDY (Turkey Building Earthquake Regulation) standards. These standards determine calculation parameters based on regional wind zone, snow load class, and earthquake zone.
PVAGE Structural Calculation Module
PVAGE automatically calculates wind, snow, and seismic loads based on project location. It generates comprehensive structural reports including profile selection, support intervals, bolt strengths, and total load distribution.
Warning: Systems installed without structural calculations may be excluded from insurance coverage. Additionally, panel detachment in wind creates serious risks for personal safety and property.
