Under specific mounting conditions, the provided values may surpass the designated maximum load capacity of a standard solar module. Snow and wind loads, capped at 5400Pa and 2400Pa respectively, have been choosen as loading pressure threshold limits.

Please, pay attention to the calculated values and make sure, that they do not exceed the given limits by the manufacturer of the solar module.

1. Specify characteristic values of your climate region

Characteristic reference values for snow loads and basic wind velocities can be found under the following links:


Snow Loads

Basic Wind Velocities


Slow Load: kN/m2
Basic Wind Velocity: m/s
The following calculations are in accordance with:
  • EN 1990 (2002) Eurocode – Basis of structural design
  • EN 1991-1-3 (2003) Eurocode 1 : Actions on structures – Part 1-3: General actions – Snow loads
  • EN 1991-1-4 (2005) Eurocode 1 : Actions on structures – Part 1-4: General actions – Wind actions
