Solar carport overhead mounting: Approval for overhead installations with transparent double-glazed / glass-glass solar modules

Transparent double-glazed / glass-glass solar modules approved for overhead installations – Image: Xpert.Digital

The real problem is that not all modules have the necessary building code approval. In fact, almost none do. Currently, we know of two solar module manufacturers who have since obtained approval for overhead installation. The modules' penetration resistance (invasiveness test) and residual load-bearing capacity were tested. The latter must be able to withstand the loads that occur (e.g., snow). Even in the event of damage, a minimum load-bearing capacity must be guaranteed. In case of glass breakage, the solar modules must be secured against falling fragments.

We work together with one of the solar panel manufacturers. Are you interested and need further information or advice?

• Background information: What are the regulations regarding building permits for solar power systems, solar carports, and solar modules?

The most impressive advantage of glass is its durability and virtually indestructible properties against weathering.

With a general building authority approval (abZ) from the DIBt, interesting solar carport overhead installations and terrace overhead glazing, as well as solar facades and balcony power plants with transparent double-glazed solar modules, can be installed. This approval permits the unrestricted use of transparent solar modules.

Everything is possible, from large-scale parking lot canopies and roofs for industrial halls to roofs for sports facilities and sports arenas.

A solar power system consists of solar modules mounted on a support structure (mounting system/substructure for solar modules). The solar power system produces direct current (DC), which is converted into alternating current (AC) via inverters and fed into the electrical grid and/or the home's electrical network.

In short, a solar power system offers significant financial advantages. Even though the initial costs are very high, the savings on electricity bills from using self-generated power will be largely offset in the future by the increased consumption of numerous electronic devices and the anticipated rise in e-mobility. Furthermore, increasingly sophisticated energy storage systems allow the electricity to be stored for later use, potentially enabling it to be sold to third parties as an additional source of income.

The foundation and essential element of every solar power system is the supporting structure. This includes the substructures for various rooftop systems and roof types such as flat or pitched roofs, as well as the mounting systems for ground-mounted and open-field systems, also known as solar parks. And let's not forget solar carport systems!

Company parking lots, parking garages, supermarkets, shopping centers and all larger ones such as Park & ​​Ride parking lots are affected by where the solar obligation will apply in the future for the respective federal state.

Solar carports are an important application for transparent glass-glass/double-glazed solar modules. While single and double carports with photovoltaics can still be considered a standard solution (although structural differences in the main and ancillary buildings sometimes necessitate custom solutions), individual solutions are always required for row carports. This starts with the different access routes, varying room layouts, and differences in the individual driveways.

Suitable for:

• More green electricity from solar carports – the solar filling station of the future
• Solar carports with electricity storage as solar charging stations for electric cars
