7. Maintenance
When properly assembled, the QRail is a reliable and trouble-free system and should require little in the way of ongoing
maintenance or repair. Nevertheless, Quick Mount PV recommends maintaining a regular inspection and maintenance
schedule. Such a program can detect and address potential problems before they become serious and help ensure the
system’s excellent long-term durability and reliability.
The following procedure pertains only to the QRail mounting system structure. Maintenance and repair of other PV system
components should be carried out in accordance with the respective manufacturers’ recommendations.
7.1 Inspection
The system should be visually inspected periodically for loose components, loose fasteners, and any corrosion. If any of
these conditions are found, the a ected components should be immediately adjusted, repaired, or replaced.
7.2 Testing
A er one year in service, it is a good practice to check the torque settings of a representative sample of system connections,
including module clamps and rail clamps. If a disproportionate number of loose connections (more than 10% of
connections) are found, it may be an indication of improper assembly and it may be necessary to take comprehensive
corrective action.
A smaller sampling of connections can be tested annually therea er. Quick Mount PV recommends keeping records of the
connections sampled each year and testing and, if necessary, adjusting previously untested connections in succeeding
years. A er all connections have been tested, sample sizes and test frequency can be reduced.
