Aluminum Heavy Duty Solar L Feet – 155mm Height for Metal Roofs

The HQ Mount Heavy Duty Aluminum Solar L Foot – a robust, high‑clearance solution for solar panel mounting on metal roofs (standing seam, trapezoidal, corrugated). With a height of 155mm, this L foot provides superior ventilation underneath the panels, reducing operating temperature and increasing power generation. As a direct solar mounting manufacturer, we deliver a complete, code‑compliant system.

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.”
