Premium Mounting Technologies (PMT) and PURUS PLASTICS, both based in Upper Franconia, are combining their expertise in the growing market for solar green roofs. Together, the companies offer an integrated solution that combines PURUS PLASTICS’ ECOgreen® modular green roof system with the PMT EVO GREEN mounting system, which was developed specifically for green roofs. The result is a cost-effective, sustainable, and easy-to-install solution for modern rooftops.

Solar green roofs are gaining in importance

The market for solar green roofs is growing rapidly. In many cities and states, green roofs are already required or specifically subsidized for new construction and major roof renovations. At the same time, the demand for locally generated solar power is increasing.

The combination of solar power and green roofs therefore offers great potential for sustainable urban development: Green roofs improve the microclimate, reduce the heating of buildings and cities, create habitats for plants and insects, and contribute to rainwater retention. Solar power systems also benefit from the natural cooling effect of the greenery, which can lead to higher electricity yields.

Two systems, one integrated solution

The direct combination of ECOgreen® and PMT EVO GREEN creates a particularly efficient overall solution. The pre-planted ECOgreen® system already provides the necessary load for the photovoltaic system. This eliminates the need for additional ballast stones.

This reduces material usage, minimizes transportation costs, and speeds up installation on the construction site. At the same time, it creates a secure integrated system that meets the requirements for modern solar green roofs and offers planners, investors, operators, and contractors greater confidence in the implementation process.

“Through this form of collaboration, we are combining our expertise and opening up new opportunities for each other in the growing solar green roof market,” says Richard Metzler, CEO of PURUS PLASTICS.

ECOgreen®: Green roof system with integrated ballast

PURUS PLASTICS has been developing solutions for blue-green infrastructure for over 30 years. With ECOgreen®, the company offers a modular green roof system that combines vegetation and the required dead load in a single solution.

The system consists of a securely interlocked modular grid of base plates into which sedum boxes are inserted. The elements are delivered to the construction site already planted with vegetation. This eliminates the need for the usual on-site establishment period, and the roof surface achieves its full functionality and appearance immediately after installation.

A particular advantage lies in the system’s dual function: The greenery simultaneously provides the dead weight required for the photovoltaic system. This eliminates the need for additional ballast stones.

The plastic building blocks of the ECOgreen® system are made from packaging and film waste collected in the "Yellow Bag" and are fully recyclable even after decades of use.

PMT EVO GREEN: Mounting solution for modern green solar roofs

PMT has been developing and manufacturing high-quality photovoltaic mounting systems in Germany since 2012. With " PMT EVO GREEN ," the company offers a mounting solution specifically designed for green roofs that optimally combines solar energy with green roofing.

The system is based on the proven PMT EVO technology and allows for flexible planning to meet a variety of roofing requirements. Depending on the green roof design, various system heights are available.

PMT EVO GREEN It also takes into account the requirements of modern solar green roofs, including row spacing and clearances between vegetation and modules. The innovative click technology enables quick and secure installation on the construction site.

An additional advantage: " PMT EVO GREEN " is based on a substructure tested by the German Institute for Building Technology (DIBt) that has received general building authority approval (abZ), thereby providing additional planning certainty for all project participants.

“The future of urban rooftop spaces lies in the smart combination of solar energy and greening. Together with PURUS, we have created a solution that combines the strengths of both systems and enables our customers to use their rooftops in a cost-effective and sustainable way. In particular, the combination of pre-vegetated delivery, integrated ballast, and the direct connection to our substructure offers significant advantages in planning, installation, and operation,” says Felix Bräuer, CEO of PMT – Premium Mounting Technologies.

Sustainable Roofs for the City of Tomorrow

Green roofs combine environmental and economic benefits. They improve the microclimate, create valuable habitat, support rainwater retention, and can often be counted toward compensation areas. At the same time, they help actively utilize previously unused roof space for energy generation and climate protection.

Together, PURUS PLASTICS and PMT are laying the groundwork for the next generation of sustainable rooftops. The combination of green roofs and photovoltaics brings together climate adaptation, biodiversity, and renewable energy generation into a forward-looking, integrated system.

Photovoltaic systems are exposed to wind and weather every day. Winter is particularly demanding on the material, as heavy snow loads increase the pressure on panels, substructures, and roofs. How can you prevent damage?

Our photovoltaic systems must be well equipped for snowy winter days. Whether on the roof or in open spaces, precipitation lands on the modules. Snow is particularly challenging. The beautiful white stuff that brings us so much joy in winter can be quite heavy when it settles on solar panels.

Although statistically speaking, the number of days with snowfall is decreasing in our region, winters like that of 2010 show that snow loads are important factors in the planning of sustainable systems. By snow load, we mean the effect of snow on a building or structure.

Why are snow loads so dangerous for photovoltaic systems?

Heavy snow masses exert enormous pressure on the modules, the mountings, and the roof. On sloping roofs, icy snow slabs and roof avalanches can pose a danger to people, animals, and equipment located around the building. Especially on flat roofs, where snow cannot slide off, it poses a risk to the roof strength and stability of the building. One cubic meter of fresh snow can weigh between 30 and 50 kg. If the snow is already compacted or even wet, 300 kg per cubic meter is not unusual. If layers of snow have already turned into ice sheets, even an apparently small blanket of snow can develop enormous weight. The Federal Office for Civil Protection and Disaster Assistance explains how homeowners can protect their roofs and buildings from snow loads.

Snow loads pressing down on a photovoltaic system can cause mechanical damage. Snow loads can cause microcracks in glass-foil modules, which impair both the performance and service life of the modules. In view of current market developments and the increasing use of glass-glass modules, special requirements are placed on the substructure due to their higher dead weight and lower load-bearing capacity. High-quality, structurally optimized installation is crucial to reduce mechanical stress, prevent module breakage, and ensure long-term system safety.

The particular challenges in snowy regions

Heavy snowfall is not uncommon, especially in southern Germany and the Alpine regions. The additional weight that can be placed on a system in winter must be included in the calculation of the total roof load. Modules and substructures designed for high snow loads should be used here in order to prevent damage. If this is not taken into account when planning a system, the resulting pressure can, in the worst case, cause the roof to collapse.

PMT – Your partner for safe and durable photovoltaic systems
As specialists in mounting systems, we offer tailor-made solutions for every roof shape – with a particular focus on potential snow loads and the load-bearing capacity of the modules used. Our PMT X118 andPMT EVO GREEN substructuresPMT EVO GREEN designed for all wind and snow load zones found in Europe.

In thePMT EVO GREEN system, the new cross-brace connection, which can also be used flexibly in the upper position,PMT EVO GREEN increased load-bearing capacity of the modules. In the PMT X118 system, the load is optimally transferred to the module by the central clamping, which also significantly increases its load-bearing capacity.

The high quality and reliability of our components is confirmed by the general building approval of our systems. In addition, we underline our quality promise to our customers with a 15-year warranty.

2023 was already considered a record year for photovoltaic expansion. Over one million photovoltaic systems and more than 500,000 storage systems were installed, according to the German Solar Industry Association. These are important steps in terms of the energy transition target. After all, a quarter of Germany's electricity needs are to be covered by photovoltaic power by 2030.

For this to succeed, growing environmental awareness, government guidelines and technological advances must be coordinated. A total of 81.4 GW of photovoltaic capacity is installed in Germany. An expansion to 215 GW is necessary to achieve the target. A high target that requires land, investment and people. According to the BMWK, 84,100 people were working in the solar industry in Germany in 2022. In 2011, there were almost twice as many. After the sharp market slump in the 2010s, the industry is slowly recovering.

However, the international stage has not stood still in recent years. New photovoltaic capacity installed worldwide rose by an average of 40 percent per year between 2020 and 2023. According to Bloomberg NEF 2023, this amounted to around 400 gigawatts of capacity alone. Falling module prices are one of the factors contributing to this. In many countries, PV energy is by far one of the cheapest forms of electricity supply. Germany has long since ceded its pioneering role to China. With 250 GW of newly installed capacity, the country is now responsible for 60 percent of global photovoltaic growth. With a total output of over 660 GW, China has left the number 2 in the table, the USA with 169 GW, far behind. Germany has slipped to 5th place.

The growing demand for PV systems

But more important than rankings and comparisons is the potential that our country has to offer. Without having to come into conflict with agriculture or nature conservation, as often proclaimed by critics, Germany could easily achieve the expansion target, emphasizes the report "Current Facts on Photovoltaics" by the Fraunhofer Institute. In the building sector alone, there is the technical potential for 1000 GW. Only ten percent of the roof potential is currently being used. Innovations are increasingly making it possible to convert existing and challenging buildings to renewable energy sources safely and sustainably. There is therefore economic development potential in this field, from which the economy, the labor market and ultimately the people will benefit.

The decisive role of high-quality assembly systems

Photovoltaic systems are a long-term investment. They should work as smoothly as possible for at least 20 years on the roof or as a ground-mounted system exposed to wind and weather. At the same time, they are expected to generate energy with maximum output. As users, we want to be able to rely on this. It is therefore not only the module and storage solutions that are constantly evolving, becoming more efficient and safer. A lot is also happening on the PV market in the area of substructures.

This is also necessary. With further expansion in Germany and other countries, the focus is also shifting to surfaces and roofs that pose particular challenges. Substructures must protect the surface and the roof and at the same time help to ensure the safety of the installation teams. At the same time, the core tasks must not take a back seat:

• Structural integrity: A stable and durable mounting system is critical to withstand the forces of wind, snow and other environmental factors.
• Increased energy yield: A correctly installed mounting system can optimize the energy output of a PV system by ensuring optimal alignment and tilt of the photovoltaic modules. This can lead to increased energy production and a better return on investment.
• Increased safety: A well-designed installation system is crucial for the safety of both installers and building users.

Our teams work every day to test our solutions and improve them based on customer feedback and our experience. It is no coincidence that our PMT EVO 2.0, PMT EVO 2.1 and PMT X118 solutions have received general building authority approval. In this way, we are helping to ensure that the industry can continue to develop in a sustainable direction.
