Modular principle rethought: ModuRack optimizes solar installation and costs

At a time when solar energy is a central pillar of the global energy transition, not only the efficiency of modules but also the methods of their installation are coming into focus. While photovoltaic panels have made enormous technological advances, installation technology has often remained stuck in traditional, labor-intensive, and potentially damaging processes. The ModuRack mounting system now introduces a fundamentally new approach aimed at simplifying installation, extending the lifespan of systems, and improving the overall economics of solar projects.

The core innovation: Rail-integrated fastening instead of point loading

The core of ModuRack's innovation is its departure from conventional clamp fastening. In conventional systems, solar modules are held at individual points by clamps screwed onto the module frame. This localized loading creates high mechanical stresses, which, particularly under weather conditions such as wind or snow loads, can lead to microcracks in the delicate glass and the underlying solar cells. Such cracks – especially in the solar cells – are often invisible to the naked eye, but gradually lead to a reduction in module performance and shorten the effective lifespan of the entire system.

ModuRack addresses this problem with a fundamentally different concept. Instead of clamps, the modules are inserted and held in place by a continuous support rail. This design ensures that the forces generated are evenly distributed across the entire length of the module frame. Stress peaks that cause microcracks are thus eliminated from the outset. The mechanical integrity of the module is maintained, ensuring consistently high performance for decades.

Significant reduction in project costs – up to 30 percent

The technical and logistical advantages of the ModuRack system are directly reflected in remarkable cost-effectiveness. The sum of these optimizations enables a reduction in total project costs by up to 30 percent, significantly increasing the attractiveness of solar investments. A key lever for this is the drastic reduction in installation time. Thanks to the intelligent click mechanisms, which replace the time-consuming screwing of individual clamps, the installation effort on the roof can be reduced by up to 50 percent. This enormous time saving leads to significantly lower labor costs, which represent one of the largest cost items in the construction of solar systems.

Furthermore, the accelerated and uncomplicated assembly process simplifies coordination between the various trades working on the construction site. Since roofing work is completed more quickly, friction points and waiting times for subsequent work, for example, by electricians, are minimized. This leads to a smoother overall project progress and reduces the risk of costly delays. Finally, the aforementioned modular design also contributes significantly to cost reduction. The reduced material and storage requirements due to fewer individual parts not only eases the burden on logistics but also directly reduces material costs and the capital tied up in inventory. In total, these savings in labor, coordination, and materials lead to an impressive overall cost reduction.

Installation redefined: simplicity and efficiency

Another key advantage of the system is its remarkable ease of installation. The installation process is described as exceptionally intuitive. Instead of time-consumingly aligning and tightening individual clamps, installers can click the solar modules directly into the prepared rails with a simple movement of their hands. This process not only drastically reduces installation time per module but also minimizes the risk of errors. The intuitive handling also makes the system accessible to less specialized installation teams, which is a significant advantage in times of skilled labor shortages.

Superior technical performance and durability

The sophisticated design of ModuRack leads to measurably improved overall technical performance. By avoiding microcracks , the solar modules retain their rated output for a significantly longer period. At the same time, the stable, flat mounting increases the resilience of the entire system to external influences. Strong wind loads, vibrations from traffic, or other weather events are better absorbed by the system, significantly increasing its mechanical resilience and ensuring the longevity of the investment.

The modular approach: logistical and economic advantages

ModuRack follows a consistent modular design principle. By reducing the number of different components, the entire logistics chain is simplified. For companies, this means easier warehousing, as fewer different parts need to be stocked. On the construction site, the risk of mix-ups is reduced, which speeds up workflows and prevents errors. This has another positive economic effect: Concentrating on fewer parts enables the purchase of larger quantities at better terms, which lowers the overall cost of the mounting system and further strengthens the competitiveness of solar projects.
