Solar-Farm Construction: Weatherable Nylon Brackets—Long-Term Durability
Solar-Farm Construction: Weatherable Nylon Brackets—Long-Term Durability For U.S. EPCs & O&M teams: Select SLS PA12 (nylon 12) with UV-stabilization (preferably black), prove it with accelerated weathering + thermal cycling, then confirm with small site pilots. Done right, nylon brackets can deliver 2–5 years of outdoor service on PV arrays while cutting tooling cost and lead time. For quotes: [email protected]. Why SLS PA12 for Outdoor PV Hardware Low moisture uptake → better dimensional stability than PA6/PA66. Typical data sheets show ~0.5–0.7% equilibrium at 23 °C/50% RH and ~1.3–1.8% at water saturation, depending on grade. Good chemical resistance to oils/fuels and outdoor contaminants. Mature SLS powders (e.g., EOS PA2200 class) with consistent mechanicals and surface finish for brackets, clips, and cable management. Key takeaway: choose PA12—but avoid unstabilized natural/white in long UV exposure. ...
