Hi Keith, Thank you for contacting us with your question about how our solar mounting (PVezRack) holds up against earthquakes. As a company, we take great pride in the quality and safety of our products, and we understand how important it is to ensure that our mounts can withstand natural disasters like earthquakes. We are happy to inform you that our solar mounts are designed and built with vibration-resistant techniques. We recommend a variety of materials and construction methods that have stood the test of time. To give you a bit of background, from the technical side, the predominant force and assessment for Australia is the wind uplift, or wind actions according to AS1170.2. For earthquake-prone areas where the earthquake load can be the dominant factor, we run a site-specific analysis and add further support/bracing to the system to ensure it complies with ASNZ4219 seismic loading. For New Zealand, we include earthquake assessments as part of our default certification as this requirement is mandatorily derived from the ASNZ5033 standard - Installation of PV in Australia and New Zealand. We just celebrated our 15th anniversary, and we have never experienced any movement of our mounting structure due to earthquakes in Australia. We understand that safety is a top concern for our clients, and we want to assure you that we take every possible measure to ensure that our solar mounts are built to the highest standards of safety and durability.
