Mounting System
A mounting system in photovoltaics refers to the totality of components used for the safe and stable attachment of solar modules to a substructure. These systems are crucial for the efficiency and longevity of a photovoltaic system.
How it Works:
Mounting systems transfer the weight of the solar modules to the underlying supporting structure, whether it be a roof, facade, or ground surface. They ensure that the modules are optimally oriented towards the sun and can withstand wind and weather conditions. Various factors must be taken into account, such as roof pitch, material properties of the substructure, regional wind load, and static requirements.
Types of Mounting Systems:
- Roof-Mounted Systems: These systems are installed directly on the roof and are particularly suitable for sloped roofs. They can be made of aluminum or stainless steel and are offered in various designs to accommodate different roof shapes and materials.
- Flat Roof Mounting Systems: For flat roofs, there are special mounting systems that can either be elevated or ballasted. Elevated systems increase the distance between the module and the roof to allow for better ventilation and heat dissipation. Ballasted systems use the weight of concrete blocks or gravel to secure the modules.
- Ground-Mounted Systems: These systems are used for the installation of solar modules in open spaces such as fields or parking lots. They typically consist of frames on which the modules are arranged in rows.
- Facade Mounting Systems: Solar modules can also be mounted on the facades of buildings. There are specific mounting systems designed to ensure a secure and aesthetically pleasing attachment.
Important Criteria for Selection:
- Static Requirements: The mounting system must meet the static requirements to ensure the safety of the installation.
- Corrosion Protection: The materials used should be corrosion-resistant to ensure a long lifespan.
- Flexibility: The system should be adaptable to the specific conditions of the building.
- Wind Load: The construction must withstand the expected wind loads.
- Cost: The costs for a mounting system vary depending on the size of the system and the complexity of the installation.
