Solar panel mounting to profiles
Three types of clamps are required to secure solar panels to the frame structure.
Stoppers for the bottom edge
These stoppers are installed exclusively on the lower horizontal rail of the frame, where they act as a safety feature preventing the panel from slipping in the event of another fastening mechanism failing. Although their use is not always essential, they represent reliable protection for your high-value PV panels despite the higher purchase price. Within the PV program, versions of stoppers are available for hooking into profile slots with edge widths of 32, 45, and 60 mm. They are manufactured from high-quality stainless steel as standard.
Side clamps
These clamps are designed for the secure mounting of the outer solar panels. Each row of panels requires a total of four side clamps – two for the left side and two for the right side. Installation takes place on both aluminum profile rails, i.e., on both the lower and upper parts of the structure. A key factor in choosing a side clamp is the thickness of the photovoltaic panel; we offer dimensions for all standard panel thicknesses on the market, specifically from 20 to 50 mm.
Mid-clamps (between panels)
These are used to fix panels by their inner edges within a single row. It is necessary to mount them on both the lower and upper rails of the PV aluminum profile frame. The total number of these clamps directly correlates with the number of panels placed in one row. Panel thickness does not play a decisive role here, as the required height is set by choosing an adequate screw length.
