Assemble renewable energy infrastructure faster and with more precision to maximize clean energy production.
Renewable Energy Fastening Solutions
No matter the energy source, power and energy providers throughout the world rely on a multitude of fastening solutions every day. They include threaded inserts, standard and unique nut products, screw thread inserts, breakstem rivets, self-locking thread systems, torque tool solutions, and drawn-arc welding systems.
Our nuts, rivets and lockbolts are used in a variety of solar panel applications: to secure panel assemblies to prevent shifting at undesignated times, assembly of torque tubes and torque tubes-motor joining in single axis trackers in PV plants, assembly of girders in heliostats or parabolic trough in CSP plants, assembly of the arms in lattices in heliostats, at pivoting point to support construction, in arm to pillar joining, and in any structural assembly of the galvanized profiles.
Roof Mounted Solar Panels
Avdel® blind rivets as well as structural blind bolts are used for the assembly of the solar panel frame. These joints, in opposite to a screw/nut assembly, can only be removed by using e.g. a grinder and thus are deterrent for a potential thief.
To eliminate welding during the assembly of the power converter, electric generator and control equipment, the customer now uses Avdel®'s Monobolt® and Avibulb® breakstem rivets for the assembly of the external body housing and external frames. For the fixing of internal frames and mounting parts Crimptite® self-tapping screws are used. Eliminating the welding process, the customer can now outsource stages of the assembly process to external work shops.
Solar Plant Assembly
Avdelok® XT lockbolts are used for the assembly of a thermosolar plant and provide the best performance if compared with other methods. Vibrations caused by wind or changes in temperature present a great challenge for fastening technologies. The great clamp load that Avdelok® XT lockbolts and collars provide remains constant throughout the life of the assembly. The danger of the joint coming loose, as could happen with screws, can be dismissed with this system thanks to the permanently swaged lock between the collar and the bolt. Another advantage is the speed of installation. This process is only based on the installation system, e.g. 734 AV tool, and cannot be altered or influenced by the worker. Consequently, assembly errors made by assembly personnel are not possible.
