SAFETY INFORMATION

RELEVANT REGULATIONS FOR MOUNTING PV TO FAÇADES.

When mounting photovoltaic plants to building façades, specific regulations must be observed as defined by the glass manufacturers. As well as the usual warranty risks such as roof leakage or damage to modules, there is an additional risk of injury to people in the event of substandard fastening or through the selection of inappropriate modules.

The following recommendations should help the planner/installer to mitigate such risks and to ensure a secure and professional design:

GENERAL RECOMMENDATIONS
  • All standards and approval conditions pertaining to construction must be observed when implementing solar projects for façades. 
  • The designated PV installer is obligated, as expert in the field, to inform the end customers of all potential risks and of required approvals, and must observe the valid standards as "State of the Art".
  • As a matter of course, each module assembly mounted to a building façade should be treated as an individual case, particularly where the deployment surface is a public building and where the area beneath the façade assembly is generally accessible.
MOUNTING VARIATIONS

 There are two fundamental variations:

  • The term vertical glazing is used if the photovoltaic module is mounted parallel to the wall, either directly on or with a specific clearance to the surface.
  • Overhead glazing is the term used if modules are mounted a certain angle, resembling a form of "canopy structure" where the area beneath the modules is publicly accessible.

In both cases, irrespective of whether damage is caused by negligence (tension in glass, incorrect mounting, thermal tension, etc.) or whether a module is damaged through external influences, there is a fundamental risk of glass shards falling from the assembly and causing injury to passers-by.

SPECIFIC RECOMMENDATIONS
  • Vertical or overhead glazing is only approved in publicly accessible areas if the possibility of injury due to falling glass fragments can be ruled out in the event of damage to a laminate glass part (including a PV module).
  • Vertical or overhead glazing is deployed using appropriate composite glass materials (generally VSG and ESG materials): The modules are protected against shattering by a laminated film which can hold glass together for a period of time after breakage.
  • Overhead laminate glass systems may have a generic type of approval which offers authorization for deployment in specific areas.
  • In addition to the materials deployed, the fastening method and the module arrangement generally have a great influence on utilization in the vertical or overhead positions.
  • As a general principle, photovoltaic modules are not approved for mounting in an overhead assembly. This applies to both framed and unframed modules. PV modules are also designed, technically, in glass-film compound format, but are nevertheless not approved for deployment as an overhead laminate assembly. More information on this subject can be obtained from the respective manufacturer.
  • In the event that PV modules are proposed as a façade or overhead solution, a specific method of fastening is generally imposed (e.g. a linear arrangement of laminated modules).
  • It is possible for a system with a non-approved design for application in overhead assemblies to be approved, as an "exceptional case" for deployment in certain projects. Approval for exceptional deployment generally requires a positive destructive test on several components (in the case of PV modules this may be more expensive than for glass components). Several test specimens are damaged and the laminate film must prove capable of holding fragments together over a specific period, guaranteeing that no dangerous shards can break free and cause injury.
