A mounting system is the technical backbone of every photovoltaic system. It ensures that solar modules are permanently, securely, and efficiently attached to the roof – regardless of wind, weather, and snow load. However, not all mounting systems are created equal: quality, design, and ease of installation vary considerably. In this article, we explain what makes a good mounting system – and how CLEVER-TILE ® is setting new standards in installation and roof protection with its intelligent solution.
What is a mounting system?
A mounting system for photovoltaics (also called a "mounting system") comprises all the mechanical components necessary for attaching the solar modules to a building. These include, among other things:
- Roof hooks or threaded rods (depending on the roof type)
- Mounting rails made of aluminum or stainless steel
- Module terminals (mid and end clamps)
- Connecting and fastening elements
The aim is to attach the modules in such a way that they remain permanently stable – while simultaneously complying with all electrical engineering and building regulations.
Structure and variations of mounting systems
Mounting systems vary depending on the roof type, building shape, and installation goal. The most common types are:
🔩 Rooftop systems
The modules are mounted on the existing roof. The load is transferred into the roof structure using roof hooks or threaded rods. These systems are particularly common on tile and bitumen roofs.
🧱 In-roof systems
Here, the PV module replaces the actual roof covering. The mounting system is fully integrated, resulting in a flat, streamlined appearance. Installation is more complex, as are the requirements for watertightness.
🏢 Flat roof systems
These use ballasted frames with supports. The mounting systems do not require roof penetration, but must be specially secured against wind.
🏞 Open-field facilities
Massive ground support systems are used here, often with ramming profiles, screw foundations or concrete slabs.
What makes a good mounting system?
✔️ Stability and durability
A high-quality mounting system can withstand extreme weather conditions for decades – from hail to strong winds. The materials used (e.g., aluminum, stainless steel) should be corrosion-resistant.
✔️ Easy and quick assembly
Time is money. Systems that impress with clever click technology or pre-assembled components save working time and reduce assembly errors.
✔️ Roof-friendly installation
A good fastening system damages neither the roof membrane nor the roof tiles. This reduces subsequent costs due to leaks or repairs – this is where CLEVER-TILE ® comes in.
✔️ Flexibility and compatibility
The system should be compatible with different module sizes, rail shapes, and roof types. This ensures flexibility for future retrofits or expansions.
Mounting systems at CLEVER-TILE ® – a clever solution
CLEVER-TILE ® takes a unique approach: Instead of laboriously modifying existing roof tiles, a specially shaped *replacement tile with an integrated roof hook* is used. This makes CLEVER-TILE ® not just a mounting system – but a complete, roof-friendly installation solution.
Advantages of the CLEVER-TILE ® system:
- 🔧 No grinding or drilling of the bricks required
- 🏠 No roof penetration – the roof membrane remains completely intact
- 🕒 Quick and safe assembly thanks to pre-assembled components
- ⚖️ Even load distribution – roof-friendly and statically optimized
- ✅ Compatible with common mounting rails and PV module sizes
Typical applications for mounting systems
🔹 Single-family houses with a pitched roof
Standard pitched roofs with tiles are the most common application. Here, CLEVER-TILE ® offers a simple, elegant solution without risk to the roof.
🔹 Commercial buildings with flat roofs
Ballasted systems are used for flat roofs – ideally combined with optimized module angles.
🔹 Old buildings and renovation projects
Special care is required with old roofs. A roof-friendly system like CLEVER-TILE ® is particularly beneficial in these cases.
Conclusion: The mounting system determines success and safety
A stable, durable, and roof-friendly mounting system is essential for a successful PV system. Choosing the CLEVER-TILE ® system means benefiting from a well-designed, comprehensive solution that combines the advantages of traditional rooftop systems with an innovative tile concept. This ensures quick, safe, and damage-free module installation. More information here
