Solar green roof – combining photovoltaics and green roofing
Solar Green System
Solar systems and green roofs are a perfect combination! A green roof heats up much less in summer than a conventional roof, thus ensuring a lower ambient temperature. Since the efficiency of most solar modules depends on their ambient temperature, a photovoltaic system on a green roof achieves a higher level of performance.
The plants on the green roof evaporate water and thereby cool the modules, which increases the efficiency of the PV system. At the same time, the vegetation protects the roof waterproofing from UV radiation and extreme weather conditions, which increases the service life of the roof. With a green roof, you are not only investing in sustainable energy, but also in climate protection and the protection of your roof. Take advantage of the synergies of photovoltaics and green roofs and benefit from higher energy yields and longer roof durability with 6 fürs Grün solar systems.
Solar Green System: Efficient photovoltaic green roofs
The Solar Green System is a ballast-supported substructure system for the secure and stable installation of PV modules. Ballasting is provided by the green roof or gravel roof structure. There is no mechanical penetration of the roof waterproofing or point loads, as can occur with conventional mounting systems. This makes the system particularly gentle on the roof and increases its longevity.
Extensive green roofing is ideal for combining with photovoltaic green roofing. The low-maintenance plants are generally short in height and benefit from the Solar Green System's water reservoir, which ensures optimal water supply for the plants.
With the Solar Green System, the lower edge of the module has a minimum distance of 30 cm from the substrate, which means that there is no loss of yield from the PV system due to plant shading. The FLL guideline for green roofs stipulates a minimum distance of 20 cm between the lower edge of the modules and the substrate, so you are on the safe side with the Solar Green System. The elevated position of the photovoltaic modules also allows snow to slide off completely and simplifies maintenance, inspection and cleaning of the system.
The Solar Green System is quick and easy to install thanks to its few components and integrated filter fleece.
The planning
The installation plan for the Solar Green System, the substructure for your PV modules on the green roof, is drawn up by specialist planners. The planning takes into account the usage requirements, the characteristics of the building and the local conditions that you specify on the checklist.
