Small Scale Offgrid Solar PV: Installation Manual
These steps explain how to fix a Solar Panel to a corrugated metal sheet type roof using
aluminium angles.
Cut the two lengths of aluminium angle at (solar panel width + 20 cm); leaving a 10cm overhang on
either side of the Panel.
Fix one length of aluminium to each end of the panel.
1. Position the first length of aluminium at the edge of the panel to mark the positions of
screws. The horizontal part of the angle should be facing away from the panel, not
positioned underneath it.
2. The screws should be positioned so that the heads, on the inside of the frame, do not
scratch the underside of the panel. A scratch could ruin the panel. Also make sure the
length of aluminium is flush with the panel frame.
3. Drill the aluminium with a drill bit 1mm larger than the screw (7mm in this case.).
4. You can mark the second angle according to the holes positions in the first.
5. Hold the aluminium to the edges of the panel again to mark the position of the holes in
the frame before drilling.
