Ultralight flexible solar modules

Lightweight solar modules for roofs with low load capacity

Flexible solar modules with a surface weight of 2.9 kilograms per square metre for flat roofs, industrial roofs, commercial buildings and existing roofs where rigid glass-and-aluminium modules cannot be installed for structural reasons.

SURFACE WEIGHT COMPARED DIRECTLY
sun42.eu flexible modules 2.9 kg/m²
Standard glass-and-aluminium modules 12–15 kg/m²

Roughly a fifth of the surface weight of conventional rooftop systems. This means structural reinforcement, otherwise required at 12 to 15 kilograms per square metre, can often be avoided on existing roofs.

No need to open the roof membrane

The flexible modules are bonded over the entire surface of the existing roof membrane. No intervention in the waterproofing layer is required.

23.5 percent module efficiency, N-TOPCon cell type

High area-related output at low weight thanks to N-TOPCon cells with 23.5 percent module efficiency.

Certified to IEC 61215 and IEC 61730, TÜV tested, 25-year performance warranty

Tested safety and durability to international module standards, with a 25-year performance warranty.

Attractive terms from one pallet

Tiered pricing from pallet quantities for installers, solar contractors and resellers. Lower total cost for purchase and installation than classic rooftop systems with mounting structures.

INSTALLATION

Mounting options

Depending on the roof structure and project requirements, the flexible modules can be bonded in several ways.

Direct full-surface bonding

Bonded directly onto the surface across the full area – no rear ventilation.

Rear-ventilated with a thick adhesive bead

The adhesive bead itself acts as a spacer, creating the option of rear ventilation.

Rear-ventilated with spacer tape

Additional spacers (spacer tape) specifically create the option of rear ventilation.

Rear-ventilated with profiles

Plastic profiles such as square tubes are bonded to the surface, creating the option of rear ventilation for the module.

All variants are purely adhesive solutions, with no additional mechanical fixings. The specific solution depends on the roof structure and the project and must be planned by qualified professionals.

PROVEN IN PRACTICE

Large-scale installation on industrial roofs

The flexible modules also reach their full potential on the extensive flat and pitched roofs of commercial and industrial buildings. The low surface weight makes it possible to cover large roof areas without extensive structural reinforcement of the roof frame.

  • No intervention in the existing roof membrane
  • Fast installation on large roof areas
  • Suitable for existing buildings with limited load capacity

FURTHER APPLICATIONS

Carports, canopies and special structures

The flexibility of the modules opens up applications that cannot be realised with rigid glass-and-aluminium modules. Curved roof surfaces, carports with a curved shape or architecturally demanding canopies can be fitted without difficulty.

  • Flexibly bendable for curved constructions
  • Ideal in combination with EV charging points under carports
  • Also suited to camping, motorhomes and marine applications
