SunLock is an Australian designed and manufactured solar panel mounting system. Utilising custom built aluminium extrusions and components, the design of the SunLock system streamlines construction and improves frame strength to greatly simplify solar panel installation.
SunLock’s significantly higher strength-to-weight ratio allows more efficient use and greater spans. Its highly versatile design offers adjustability and expandability to suit any size job.
SunLock is backed by a 10 year warranty and is fully compliant with the Australian/New Zealand Standard on Wind Actions AS/NZS1170.2, making it suitable for a wide variety of building types and climatic zones.
Backed by a 10 year warranty from an Australian company, SunLock is the trusted and proven name in solar PV mounting systems.
Supplied with clear & comprehensive installation instructions, including engineering drawings and AS/NZS1170.2:2011 compliance certificates, a properly installed SunLock frame is the simplest way to save time and money whilst ensuring compliance with CEC guidelines.
