The main differences between photovoltaic seismic supports and ordinary photovoltaic supports lie in the functional design and the material application :
Functional design
Ordinary photovoltaic brackets mainly adopt gravity support systems, which only bear the static loads of photovoltaic modules (such as their own weight, wind pressure, etc.). In extreme weather or earthquakes, they may cause structural damage due to lateral swinging.
Seismic supports adopt the principle of triangular stability. Through a rigid structure, they comprehensively bear the longitudinal and transverse forces generated by earthquakes, reducing the displacement of equipment and pipelines and lowering the risk of secondary disasters.
Materials and Maintenance
Ordinary brackets are mostly made of materials prone to rust (such as common steel) and require regular maintenance (such as painting and maintenance every 2-3 years). Seismic supports are usually treated with surface galvanization (such as aluminum alloy or galvanized steel), which makes them more corrosion-resistant and requires less maintenance in the later stage.
Applicable scenarios
Ordinary brackets are suitable for scenarios with lower stability requirements, such as residential rooftops and small photovoltaic power stations. Seismic supports are mostly used in large ground-mounted power stations, industrial plants and other scenarios that need to cope with extreme environments or earthquake risks.
