Its snap-in function is said to make it easier for fitters to handle on roofs. The framework also includes preassembled elements and can be used on all types of roof. The preassembled cross-connectors and module clamps are clipped into the transverse carriers with special clips, then lock in automatically.
The manufacturer says prefabricated components shorten assembly time by up to 20 percent compared with previous installation systems. Assembling the system on tiled roofs is said to be particularly simple. The installer fastens the roof hook in the usual way and then need only press the transverse carriers into the preassembled Futura Siplex profile clip.
Donauer Solartechnik is also presenting products for island grids at the trade show, including its Mobile Solar Power System (MSPS). This is a container holding a complete photovoltaic power supply system and is designed for extreme climatic conditions. Construction takes one day, and then it’s ready for use, providing an alternating-current output of 16 to 118 kilowatts.
