Frequently Asked Questions
Is the IBR kit compatible with all solar panels?
Yes. The IBR mount works with standard 60-cell and 72-cell solar panels with a thickness of 30mm–45mm, widely used in South Africa.
Can this be installed on tiled roofs?
No. The IBR kit is specifically designed for ribbed seam metal roofs. For clay or concrete tiled roofs, see our Tiled Roof Solutions category.
Is the IBR kit suitable for coastal or high-humidity areas?
Yes. All clamps and fasteners are made from shot blast surface finished grade 304 stainless steel, T5-6005 natural anodised aluminium and grade 304/A2-70 stainless steel (fasteners), providing excellent corrosion resistance for coastal and high-humidity installations.
