The project site is situated in Hsinchu county, also known as wind city. Due to this meteorological factor, solar system must be constructed with strong wind load capacity. Juno series clamp holder is adopted to fix the anodized mounting structure in position on top of the round standing seam roof of the cosmetic factory. To ensure safety, Juno series clamp holder has been structurally analyzed and certified. A single unit of clamp holder is proven to be able to withstand 281kgf and wind speed up to 37.5m/s, a force equivalent to Beaufort scale 13.
