Get more information about solar PV roof fixing systems at the Ecofirst website. Solar PV tracking systems move the PV panels to track the sun, and are claimed to produce up to 30 per cent more electricity than a static array. The downside is the additional cost.
Can wind damage solar PV modules?
Wind load can be dangerous to solar PV modules. If they are ripped from their mooring, severe damage might occur. This applies to solar PV modules on flat roofs, ground-mounted systems, and sloped roofs. Wind load can have a significant impact on them.
What type of fixing system is used for solar PV panels?
The type of fixing system used will depend on whether the solar PV panels are going to be: ground mounted. Solar PV panels can be retrofitted onto an existing roof, on top of the tiles or other roofing materials, using roof anchors (also called roof-hooks or brackets), mounting rails and clamps.
