Photovoltaic (PV) systems are power generation systems installed on rooftops and ground-mounted structures to produce electricity from solar energy. In rooftop PV installations, supporting structures, mounting connections, cable penetrations, and roof penetrations integrate with a variety of construction materials to form a complete installation.
Ensuring the long-term reliability of PV systems requires more than proper mechanical installation. Roof penetrations and service entry points must remain watertight, products exposed to the elements must provide excellent UV resistance, and thermal movement between dissimilar materials must be accommodated throughout the system's service life.
Adhesives and sealants are commonly used in the following PV system applications:
Cable entry points
Roof penetrations
Mounting bracket perimeters
Aluminum profile joints
Cable tray installation
Installation of inverters and auxiliary equipment
Outdoor electrical junction boxes
Roof maintenance and repair details
Service penetrations
Metal roof joints.
Adhesives and sealants complement mechanical fastening systems while helping to preserve the integrity of the building envelope.
Technologies Used
Neutral Silicones
Neutral-cure silicones are used to provide long-lasting sealing around roof details and cable penetrations exposed to outdoor environmental conditions.
Typical applications include metal roofing systems, glass surfaces, roof penetrations, and outdoor electrical enclosures.
Polyurethane Sealants
Their elastic properties help accommodate movement caused by temperature fluctuations.
Polyurethane sealants are suitable for metal joints exposed to vibration and for selected roofing applications.
Hybrid Polymer Technology
Hybrid polymer-based products provide excellent adhesion and long-term elasticity between the different construction materials used in solar energy systems.
Their principal advantages include outstanding UV resistance, excellent weather durability, high adhesion to metal substrates, permanent elasticity, and vibration-damping properties.
Typical applications include aluminum mounting profiles, cable tray installation, metal detailing, and roof maintenance applications.
