What is Mounting System?
The racking and brackets that secure solar panels to your roof, designed to withstand wind, rain, and snow.
Quick Answer
In Ireland, mounting systems must be rated for wind speeds of at least 130 km/h due to Atlantic storms. Most Irish installations use on-roof (flush-mounted) systems on pitched roofs. For slate and tile roofs, different hook types are used. In-roof (integrated) systems that replace roof tiles are also available but less common. All mounting hardware should be marine-grade aluminium or stainless steel due to Ireland's damp, salty climate.

Mounting System Explained
A solar panel mounting system (or racking system) is the structural framework that attaches panels to a roof or ground surface. For pitched roofs, roof hooks bolt through tiles into rafters, and aluminium rails are attached to the hooks. Panels then clip onto the rails. For flat roofs, weighted ballast systems or tilt frames are used. Mounting systems must withstand local wind loads, carry the weight of panels, and maintain a watertight seal at all attachment points.
