Functionality

Determine the centre distance of the STSI double-threaded screws according to the snow and wind loads of the system installation area and inclination of the roof.
Identify the position of the STSI double-threaded screws depending on the load-bearing structure and the layout of the installation (use SOLARPANEL-FiX for the design).
Drill the support according to the diameter of the screw.
Tighten the STSI double-threaded screw until the gasket is fully in contact with the roof covering.
Carefully seal the exit point of the screw from the roof with bituminous sealant in order to improve waterproofness.
Connect the Solar rail to the upper part of the screw by inserting SSP or MW connection plates, adjusting their height using the MU nuts.
