Force requirements for oblique installation of photovoltaic panels

Are all PV products covered by IEC61730 'photovoltaic (PV) module safety qualification?

In future it is expected that all PV products will increasingly be covered by International standard IEC61730: 2004 ‘Photovoltaic (PV) module safety qualification’.

Can a structural engineer design a photovoltaic system?

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.

Are there any UK standards relating to a PV installation?

While many UK standards apply in general terms, at the time of writing there is still relatively little which specifically relates to a PV installation. However, there are two documents which specifically relate to the installation of these systems that are of particular relevance:

Does a cluster of solar photovoltaic panels have drag and lift forces?

A fully 3D numerical analysis of turbulent flow over a cluster of solar photovoltaic (PV) panels was performed in order to assess the total drag and lift forces, comparing the results with the values from the guidelines of the national standard.

What are the requirements for a PV installation?

Virtually all domestic PV installations will fall under the scope of Part P. Part P requires the relevant Building Control department to be notified and approve the work. There are two routes to comply with the requirements of Part P: Notify the relevant Building Control department before starting the work.

What are the peak force coefficients for panels 1 and 2?

The minimum peak force coefficients, which are observed for panels 1 and 2, occur for 135° wind direction, 30° panel inclination, for panels located back and front respectively. Additionally, panel 3 peak force coefficients appear for 180° wind direction, 40° panel inclination and back location.
