Product Profile > IBC FrameFix

A new PV module frame reinforcement system IBC FrameFix for installations in heavy-snow regions. Designed especially for large-scale, vertically-mounted PV modules, the new frame reinforcement system consists of 4-millimeter (mm)-thick, plastic-coated, weather-resistant steel cables. For ease of installation, the cables are simply clamped onto the back of the PV module – quick and easy - thus strengthening the framework effectively. With the IBC FrameFix, PV modules are significantly stronger and more protected against sliding snow loads. This has already been proven by tests conducted by TÜV Rheinland with its newly developed test method for inhomogeneous snow loads on PV modules. In areas with heavy snowfall, PV systems are exposed to particularly high snow loads. The weight of the snow and its down-force can overstress and deform the lower edge of the module frame, especially in the first row of modules on the roof, thus damaging the modules. To solve this problem, IBC SOLAR has developed the frame reinforcement IBC FrameFix for PV modules. According to the current testing standard IEC 61215 for photovoltaic modules, the mechanical load test only requires a uniformly distributed load in horizontal position. For modules that are installed on sloping roofs, snow accumulations might lead to an inhomogeneous distributed snow load putting unbalance pressure on the modules. Additionally, the incline of the roof top where the modules are located means gravity will pull the snow load down and put a heavy burden on the stabilizing frame of the PV modules, potentially resulting in broken modules. This occurs relatively rarely, but the chance is always there. To counteract such events, IBC Solar developed an additional stabilizing retainer for module frames, the IBC FrameFix. The IBC FrameFix is a robust steel cable construction which is barely visible and is fixed on the back of the module. It is suitable for PV systems with a module frame size of 1660-1680 mm length, 990 mm width and 40-50 mm height, as well as for retrofitting such systems. The frame reinforcement is mounted with only a few simple steps and does not require special tools or additional installations on the roof. It is attached to the module by tightening it with a screw. Additional drilling on the frame or work on the retaining system is not necessary. With the FrameFix, the down-forces of snow are directly routed through the module clamp to the carrier profiles. This effectively increases the bearing capacity of PV modules in a quite simple way. The IBC FrameFix will be available starting October 2012 and has already been tested on a load-applying mechanism developed by TÜV Rheinland for analyzing the effects of inhomogeneous snow loads under real-life conditions. IBC SOLAR significantly supported this development with test series and field data.
