Zinc roof solar module attachment optimized bolt-and-nut installation
Zinc roof attachment solar installation
– Zinc roofs are generally composed of vertical joints (stems) and flat plates, and are fixed with clamps that can be set up without drilling, which is relatively easy. However, for this project, the installation is a bolt-and-nut type attachment (perforation type) construction, so maintaining airtightness and reinforcing waterproofing are key.
Installation Components
– Modules: 5 Hyundai 635W solar panels (3.175kW in total)
– Inverter: Korean 3.5kW
– Structure: Aluminum rail + bolt-nut fastening bracket
– Waterproofing: EPDM rubber pad or silicone caulking
Summary of construction process
– We have made a detailed and personalized process for this installation project to ensure an optimized, top of the line quality experience. The solar installation process begins with selecting and marking the optimal rail fixing locations on the zinc roof panel. Once marked, dedicated drills are used to create holes, which are then reinforced with rubber pads and sealed with silicone to ensure waterproofing. Aluminum rails are securely fastened using stainless steel bolts and nuts, followed by the placement of high-efficiency Hyundai 635W solar modules, which are secured with middle and end clamps. Afterward, the inverter is mounted on a wall and connected via DC and AC wiring to complete the energy transfer system. Finally, grounding is installed for safety, and the system undergoes a real-time power generation check to confirm proper operation and readiness for use.
Important Takeaways
– Waterproofing insulation is essential when drilling zinc roofs (use silicone/EPDM pads to prevent water leakage). If the roof is thin, fastening according to the location of the substructure (timber/stud) is necessary. Additionally, securing fastening strength against wind load is essential (at least 4 to 6 points fixed). Additional fastening devices are also recommended for end modules in case of typhoons and strong winds.
