Calculating wind loads on solar panels.

Wind loads are important consideration in structural engineering in the design of a structure. In fact most in the energysage panel database are rated to withstand significant pressure specifically from wind and hail. Solar panels hold up well in high winds. Today s photovoltaic pv industry must rely on licensed structural engineers various interpretations of building codes and standards to design pv mounting systems that will withstand wind induced loads.

Use add appliance to add an empty row and the x button on the right to each row to delete that row. The pv array should be mounted a maximum of six inches above the roof surface. The approach is applicable to pv modules mounted on rooftops that are no more than 60 feet high when the pv array is oriented parallel to the roof surface and when the mounting structure is sufficiently rigid. Wind speed the height of the panel above the roof and the relative location of the panel on the roof.

The euractive roofer project undertook numerous wind tunnel tests using scale models of roofs with panels as well as testing theoretical calculations that can in time form the basis of a european standard. The limiting factor for solar panel wind resistance is almost never the panels themselves. 2 twoupwindsectorsextending45degreesfromeither side of the chosen wind direction are the markers. Generally solar panels are highly resistant to damage from windy conditions.

When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds especially if the building is located in an area known for inclement weather. 4 the exposure with the highest wind loads is chosen for that. Adding to skyciv s already list of free tools is the new wind load calculator for asce 7 10 as 1170 2 and en 1991 ec1 this easy to use calculator will display the wind speed by location via a wind speed map as prescribed by the above building codes. Determining wind and snow loads for solar panels 10 example calculations in the following example we outline how a designer should calculate the effect of wind and snow on a pv module for commercial buildings based on few assumptions and using main wind force resisting systems design.

By step procedure for calculating wind loads on pv arrays. In order for a structure to be sound and secure the foundation roof and walls must be strong and wind resistant. 3 use section 1609 4 2 and section 1609 4 3 to determine the exposure in those sectors. When you want to install solar panels it is vital to understand certain features of the roof and the solar panels.
