Schletter has engineered solar mounting in Bavaria since 1968, with more than 60GWp installed across 110 plus countries. PowerStore carries the ProLine pitched roof system: Pro rails, RapidPro clamps, and roof attachments.


The ProLine system pairs aluminum Pro rails with click-in RapidPro clamps that carry an integrated grounding pin, and every project gets a structural report from the free Schletter Configurator sized to real wind and snow loads.
PowerStore lists Pro 35, Pro 50, and Pro floor profile rails in contractor bundles, RapidPro end and mid clamps, Rapid2+ Pro SML, Fix T-K Pro, SingleFix Pro, and RapFix Pro attachments with matching hardware. Compare finishes and pack counts by SKU below.
Our team helps installers match Schletter attachments to the roof type, plan rail and clamp counts per array, and keep orders inside the Schletter system so the guarantee holds, with practical product guidance and fulfillment support.


Rapid2+ Pro SML handles metal and bitumen shingle roofs, Fix T-K Pro mounts on shingle over solid decks, and SingleFix Pro fastens to trapezoidal panels. RapFix Pro adapts third party seam clamps.
Yes, one clamp covers nearly every standard panel. RapidPro end and mid clamps accept module frames 30 to 47mm thick, in portrait or landscape, with a grounding pin built into every clamp.
Schletter backs the metal components with a 25 year guarantee covering production related material faults that affect structural safety. It requires expert installation and keeping the system all Schletter parts.
