THE SOLID BASIS
LORENZ solo-basic
LORENZ solo-basic is the mounting system built to last: longevity of materials matters not only in house construction but also in mounting a PV system. The highly cost-effective LORENZ solo-basic mounting system uses corrosion-resistant aluminum. Its mounting rail with lateral connections is designed for all load requirements:
Solo-basic light for low loads and solo-basic strong for high loads.
The attachment can be made directly to the exceptionally robust aluminum roof hook. This mounting system easily compensates for roof irregularities, ensuring a uniform surface for the entire PV system.
