Load-bearing capacity verifications for installation of photovoltaic systems

Load-bearing capacity verifications are essential for the installation of photovoltaic systems on existing structures such as roofs of residential buildings, industrial and production-type sheds, and any other surface-sloped or flat-that lends itself to the purpose. These assessments are necessary in order to determine whether the existing structures can support the additional load posed by the new photovoltaic panels and allow for the identification of the best anchoring system to the roof. The verification process begins with a thorough inspection of the structure and collection of information about the building, including architectural and structural drawings, materials used, and general condition. The next steps involve:

  • The geometric survey of load-bearing structures and site investigations concerning the characteristics of building materials
  • The calculation of the bearing capacity of the roof and elements
  • The calculation of the total and additional weight of the photovoltaic system
  • The verification of design specifications
  • The determination of load and anchorage requirements.
  • The structural reinforcement measures, if any
  • The installation of the photovoltaic system in accordance with design specifications

In assessing load-bearing capacity, both static load-relating to the constant weight of the PV system and its components-and dynamic load due to wind, vibration and other factors that may affect the structure over time should be considered. At the end of the verification process, design guidance is provided regarding the most appropriate system for anchoring new PV panels to existing structures.

Teknoprogetti Engineering Srl is also able to follow the construction and installation phase of the system and issue the Certificate of Static Suitability (CIS) as a guarantee and protection of the works and the investment supported by the client.
