Racking & Tracker Installation
Mechanical assembly and installation of fixed-tilt racking and single-axis tracker systems.
Lab Solar provides mechanical installation crews for fixed-tilt racking and single-axis tracker systems on commercial and utility-scale ground-mount solar projects. The scope covers the structure between the driven foundations and the modules: bearings, torque tubes, structural braces, rails, module-support components, and the mechanical portions of tracker drive lines.
Racking and tracker work rewards repeatability. Once the first rows are set correctly and the crew has the manufacturer's sequence, hardware, and torque values in hand, production comes from consistent assembly rather than from rushing. Lab Solar builds the scope around the tracker or racking manufacturer's installation manual, the project drawings, and the field direction of the general contractor or EPC.
Because racking sits directly on the foundation scope and directly under the module scope, tolerance issues surface here first. Lab Solar raises foundation and component problems while crews are still in the affected rows, rather than passing them downstream to the module installation crew or into the closeout punch list.
Where this scope fits
After foundations
Racking begins on rows the foundation crew has released. Post tolerance issues found during assembly are documented and returned to the project team or corrected under the remediation scope.
Ahead of modules
Alignment, torque, and hardware completion are confirmed before module crews move in, so the array is not re-opened after modules are set.
Through mechanical completion
Mechanical QA walks, torque verification, and tracker adjustment items are closed out with the project team.
Included in this scope

- Row alignment and mechanical adjustment
- Mechanical QA/QC walks and punch-list corrections
- Component replacement for damaged or short-shipped parts
- Assembled to the manufacturer's installation manual and project drawings
- Torque values applied and verified as specified, not estimated
- Component shortages and damage reported with row and location detail
- Crew size scaled to the production rate the schedule actually requires
Questions project teams ask
Does Lab Solar install single-axis trackers?
Yes. Single-axis tracker installation, including bearings, torque tubes, structural components, and mechanical drive-line components, is a core scope.
Does Lab Solar install fixed-tilt racking?
Yes. Fixed-tilt racking assembly and installation is performed on commercial and utility-scale ground-mount projects.
Does Lab Solar follow the tracker manufacturer's installation requirements?
Yes. Assembly sequence, hardware, and torque requirements come from the manufacturer's installation manual together with the project drawings and field direction.
Can Lab Solar perform torque-to-spec and mechanical QA work?
Yes. Hardware installation to specified torque, mechanical QA walks, and correction of mechanical punch items are included in the scope.
What happens when racking crews find foundation tolerance issues?
They are documented by row and location and raised with the project team while crews are still in that area, so corrections can be made before modules are installed.
Scopes that often run with this work
Lab Solar can support a single defined scope or provide crews across multiple phases of a commercial or utility-scale solar project.
