Galvanised steel rails are used for mounting solar panels due to their robustness, ability to resist corrosion, and overall strength. These rails are especially suited for outdoor environments as they are coated with zinc. Their high strength-to-weight ratio ensures a strong and stable foundation for solar panels, which is essential for maintaining the integrity of the solar array in windy or stormy conditions. Additionally, they are compatible with a broad range of mounting hardware and accessories. Rail-based installations offer several advantages over rail-less alternatives:
- Versatility: rails provide a flexible framework for mounting solar panels, allowing for adjustments and modifications as needed. This versatility is especially beneficial for installations on complex or irregular roof surfaces.
- Uniformity: rails ensure a consistent mounting structure across the entire solar array, promoting a uniform appearance and facilitating easier maintenance and future upgrades.
- Enhanced airflow: by elevating the solar panels slightly above the roof surface, rails can improve airflow underneath, helping to reduce heat buildup and improve the overall efficiency of the system.
