      Why 155mm Height? Better Cooling = Higher Power

      Solar panels lose efficiency as temperature rises. Our 155mm L foot creates an air gap that allows natural convection, reducing module temperature by up to 10°C compared to low‑profile mounts. This translates to 5‑8% higher annual energy output – a significant ROI advantage. For the regulations about solar panel distance to metal rooftop, Poland renewable energy regulation request at leasy 70mm, while Longi panel suggested 100mm. 

      “The 155mm height made a real difference – our client reported lower inverter losses on hot days. The EPDM seal saved us from callbacks. A well‑engineered product.”
