What solar mounting system do I need for an IBR roof?

Use the IBR Solar Bracket Universal to attach galvanised rails to IBR sheet metal roofs. The bracket hooks under the raised rib of the IBR sheet and tightens from below without penetrating the sheet. Pair it with the 3.2m or 6.4m galvanised rail, mid clamps, and end clamps to complete the installation.

Can I use the same mounting system on a tile and an IBR roof?

No. Tile and IBR roofs require different brackets. The Tile Roof Mounting Bracket fixes to the tile batten using the M10 x 200mm hanger bolt and is not interchangeable with the IBR bracket. The corrugated roof solar mount is a separate product again for round-profile corrugated sheeting. Choose the bracket that matches your roof profile before ordering rails and clamps.

How many mid and end clamps do I need per solar panel?

Each panel typically requires 2 mid clamps on the sides shared with adjacent panels and 2 end clamps on the outer edges. For a 10-panel array in a single row, you need 2 end clamps at each outer end and mid clamps at each internal join. SP-Energy can help calculate the correct clip and clamp quantity for your panel count and array layout.

Does a solar mounting system affect energy production during loadshedding?

The mounting system itself does not affect output. However, correct roof orientation and tilt angle achieved through proper bracket selection do affect how much energy your panels produce daily. Panels mounted at the correct angle on a north-facing roof in South Africa consistently outperform panels on poorly oriented mounts, regardless of inverter or battery size.

Do the galvanised rails rust in South African coastal conditions?

Galvanised steel mounting rails resist corrosion in most inland and mild coastal conditions. For properties within 5km of the ocean in areas like the Western Cape and KwaZulu-Natal coast, consider discussing aluminium rail alternatives with SP-Energy before ordering. The standard galvanised rail range is well suited to inland Gauteng, Free State, and Mpumalanga conditions.
