This explains the basics of what needs to be taken into consideration when putting a solar array on your roof.
Tin Roof (Roof Screws)
This is by far the easiest option – we love the typical Australian corrugated roof! We use a simple aluminium L foot with a heavy gauge stainless roofing screw – NO new holes required as we reuse the current screw holes.
See a example on a trim deck roof, again just reusing an existing roof screw hole.
Tiles come in all shapes and sizes, they can be loose and easy to move or tight fitting like lego.
- A standard application will be to lift a tile and insert a stainless steel roof hook.
- A tile that’s very tight fitting will need a special low profile bracket, perhaps the tile may need some grinding for precise fitting. See here
- Impossible to move – often if we are working close to the ridge capping or tiles are impossible to move we move to a water tight bolt. These bolts are specifically designed to seal the roof as they are tightened in position. See here and here
- SLATE is by far the biggest challenge – but not impossible.To retrofit is quite a project, so we often work with the roofer as the slate is being placed. We use a special solar slate system in these situations. The other option if replacing tiles, is to consider a nu-lok solar tile system. Typically Australia Wide solar will work with your ‘roof state tiler’ on these projects.
With a flat concrete roof we use a stainless steel threaded rod installed directly to the roof. After the rod is installed, water proofing will be arranged to establish a permanent water tight seal.
Klip Lock Roof / Standing Seam (No roof Screws)
For a Klip Lock roof we use a special clamp that grabs onto the seams. The Clamps in position are very strong and mean no new roof holes.
Frames come in many forms and can be positioned in many places. We have frames from ground level through to 60 floors up. Every design is bespoke to produce the best yields for the customer. Often North facing, however not all the time, read more.

Attaching the panels to the rails
All these mounting systems require some rail to secure the panels to the various fixings. Panels will have small gaps between them and also some small sections of rail overhang as seen HERE
