Longer service life for solar modules
Our innovative repair solution, KremSol Repair, makes it possible to effectively reprocess damaged backsheet laminates and helps to significantly extend the service life of the modules. This not only reduces the amount of material and energy required to manufacture new modules, but also makes an important contribution to reducing the carbon footprint. Extending the service life minimises waste, conserves valuable resources and promotes a sustainable circular economy – for greener and more efficient solar energy.

Efficient construction and the highest quality
KremSol Repair consists of a specially developed combination of high-quality films. Each film has a specific function to ensure optimal performance and durability.
The films are permanently bonded to each other using an adhesive specially developed by Krempel for photovoltaic applications. The unique structure of KremSol Repair is composed of three high-performance materials:
- Outer film PET: UV and hydrolysis stable
- Inner film PET: Insulation protection
- Pressure-sensitive PSA* adhesive: For optimal adhesion
- Release film: Protection of the PSA adhesive
*Pressure Sensitive Adhesive
The clever solution
The repair films are particularly suitable for operators, investors and managers of solar farms, as well as for solar dealers and service providers in the field of maintenance and repair.
Thanks to the simple and quick application, damaged modules can be repaired directly on site, which significantly reduces production and yield losses.
Simple and quick to apply
Instead of replacing the entire solar module, KremSol Repair offers a simple and cost-effective solution: the high-performance repair backsheet enables quick recovery of functionality – without disassembly.
Clean the surface of the damaged PV module thoroughly to remove all dust and grease. Use a suitable cleaning agent, e.g. IPA (isopropanol).
Peel off a piece of the protective film and fold it back. Align the repair film exactly and carefully press on the back.
Make sure that KremSol Repair is applied without bubbles. To do this, gradually peel off the remaining protective film with a squeegee and press the adhesive surface evenly over the entire width.
