Simrit debuted a theft-proof solar retaining clip for use with frameless photovoltaic (PV) thin-film modules and its latest ethylene-propylene-diene-monomer (EPDM) rubber compound at Solar Power International 2011 this week at the Dallas Convention Centre (booth 6831) in Dallas, Texas.
The solar retaining clip's innovative design provides for fast and easy assembly, while also reducing damage typically incurred by movement, installation or environmental conditions. The state-of-the-art structure ensures homogeneous surface pressure, combined with tolerance-compensating silicone layers, to reduce module damage caused by movement. This results in an overall balance of systems (BOS) cost reduction due to the longer service life of the frame, as well as reduced warranty costs and labour savings.
Simrit's new solar retaining clip requires no mounting hardware and only two essential parts. The ergonomic solution includes a bolt-free fastening clamp that is attached to an aluminium profile to help prevent theft, a typical challenge with solar panel installations. In addition, the solution offers fast two-hand assembly, is compatible with industry standards and certifications and doesn't require electrical grounding.
The 70 EPDM 135151 material, which has garnered Underwriters Laboratories (UL) 1703 certification, is applicable for o-rings used in sealing applications of photovoltaic (PV) connectors and junction boxes used in solar energy systems. Also, according to UL, manufacturers can achieve end-product certification more efficiently and cost effectively if the critical components that are used in PV modules are already tested and certified by the organisation. UL has set minimum requirements for superstrates, substrates, encapsulants, adhesives, sealing materials and potting compounds used for fabricating PV modules or components based on the following criteria: flammability, resistance to ignition, thermal endurance and electrical properties.
