The ValkPro+ mounting system for flat roofs was expanded some time ago to include extra-long back plates and mass carriers. Van der Valk has also changed the design of the mounting holes in the back plates to increase adjustability. As a result, solar modules with a length of up to 2,320 millimetres can now be mounted.

For east-west installations and a standard pitch of 2,300 millimetres, the maximum permissible module width is 1,070 millimetres. However, due to the modular principle, the project can also be carried out with 1,200 millimetre wide solar modules if a pitch of, for example, 2,500 millimetres is chosen.
Higher loads on larger solar modules
The Valk Pitched mounting system for pitched roofs has also been expanded, with new length dimensions for the Side++ profiles. These can be used for modules with a maximum width of 1,052 millimetres without having to be sawn off or extended.
The loads on larger solar modules are increasing: The wind and snow load on the module must be calculated and compared with the maximum permissible load of the module. In most cases, the calculation shows that larger solar modules can also be fastened in the usual way. For very high roofs or in locations with very high wind speeds, it may be necessary to reinforce the solar modules.

The manufacturer offers various standard solutions for this. For example, an additional module support can be attached or high mounting can be chosen instead of transverse mounting. When calculating a project in Valk PV Planner, you can enter any module size. (mfo)
