ModuRack MagicSolar System: The future of photovoltaic installation

At the heart of the partnership is ModuRack's patented MagicSolar system, which represents a completely new approach to photovoltaic installation. This innovative system was developed to lead the solar industry from the traditional panel era to the system era, significantly reducing both hardware and software costs. The MagicSolar system is distinguished by its assemble-ready concept, in which the components are prefabricated at the factory and optimized for extremely quick and easy on-site installation.

The technology is based on years of research and development and addresses the key problems of conventional installation methods. While traditional systems are often complex, time-consuming, and error-prone, the MagicSolar system offers a consistently optimized solution from manufacturing to final installation. The system is particularly interesting for rooftop systems and solar parks, where time and cost savings are crucial. Factory prefabrication ensures consistently high quality and significantly reduces the risk of installation errors.

The rail-integrated fastening as a core innovation

With its rail-integrated fastening system, ModuRack has developed a completely new fastening concept that revolutionizes traditional solar mounting. Conventional methods subject modules to selective clamping loads, which can cause microcracks in both the glass and the solar cells, leading to performance degradation. ModuRack's innovation, however, holds the modules evenly on a rail along their entire frame length – without the need for selective clamping loads. This even force distribution prevents the formation of microcracks in the glass and cells, thus ensuring a longer service life and greater reliability of the solar modules.

The rail-integrated system utilizes a precisely engineered geometry that optimally engages the solar modules with the mounting rail. This technology utilizes advanced materials science and precise manufacturing techniques to ensure a perfect fit between the module and the rail. The rails themselves are constructed of high-quality, corrosion-resistant aluminum, ensuring durability and stability under all weather conditions. Integrating the mounting function directly into the rail eliminates the need for additional mounting components, thus reducing both material and installation costs.

Installation becomes child's play

The ModuRack MagicSolar system makes installation a simple process based on the "as easy as 1, 2, 3" principle – modules are simply clicked into the rail. This innovative installation method completely eliminates time-consuming screwing and enables intuitive handling even for less-specialized installers. Studies show that modern snap-in systems can reduce installation time by 15 to 37 percent compared to conventional rail systems. This time savings leads to significant labor savings and allows installation teams to complete more projects per day.

Simplified installation also reduces the need for highly specialized professionals, which is crucial in times of skilled labor shortages in the solar industry. The system is designed to be installed using standard hand tools, eliminating the need for specialized equipment. The modular design also allows for systems in various configurations and sizes without the need for complex on-site adaptations. This flexibility is particularly advantageous for varying roof geometries and installation conditions.

Superior technical performance

The MagicSolar system offers superior technical performance by eliminating microcracks through uniform force distribution. This innovative load distribution results in a longer service life for solar modules and improved mechanical resilience against wind and vibration. The even force distribution across the entire frame length significantly reduces mechanical stress in the modules, which has a positive impact on long-term performance. Studies show that point loads from conventional clamping systems can lead to microcracks in the solar glass, which reduce energy yield in the long term.

The system offers outstanding resistance to extreme weather conditions, including high wind and snow loads, which is particularly important in European climates. The robust construction and precise manufacturing quality ensure reliable performance throughout the system's lifetime.

Modular kit approach

ModuRack's modular approach means fewer different components, resulting in simplified inventory management, larger quantities, and better purchasing conditions. At the same time, the risk of mix-ups on the construction site is reduced, further improving installation quality and speed. The system is based on standardized components that can be used in various combinations to meet diverse installation requirements. This modularity allows installers to implement a wide variety of projects with a limited set of components.

The modular approach also extends to packaging and logistics, with components being assembled for optimal transport and handling on-site. Pre-kitting of fasteners and components reduces the number of different parts on site and minimizes the risk of errors or forgotten components. The standardized approach also enables better quality control in manufacturing and leads to consistent installation results. Installers can familiarize themselves with the system more quickly, as they don't have to learn new components and installation procedures for each project.

Market potential in Germany and Europe

The European photovoltaic market offers enormous growth potential for the partnership between ModuRack and Xpert.Digital. Germany leads the largest and fastest-growing rooftop solar PV market in Europe, with over 100 gigawatts of installed capacity and a market share of one-quarter of the EU market. In Germany alone, over one million new solar installations were launched in 2024, adding an additional 17 gigawatts of capacity. The country is aiming for 215 gigawatts by 2030, with annual increases of approximately 22 gigawatts.

The German market is particularly attractive, as the majority of new systems installed in 2024 were smaller than 30 kilowatts peak, making Germany by far the largest residential market in Europe. Self-consumption segments are the driving force of the future PV market in Germany, with the potential of rooftop solar alone enabling an installed capacity of around 200 gigawatts peak. This development is being driven by ambitious policy targets at the EU and national levels, technological advances, and the increasing demand for energy independence.

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.
