Commercial Solar Installation
Step up to large-scale. Master the skills needed for commercial rooftops, carports, and ground-mount projects, where the stakes, scope of work, and compensation are higher.
About This Course
Commercial solar installation requires a different skill set than residential work. You're dealing with larger arrays, three-phase electrical systems, ballasted and mechanically attached racking, higher DC voltages, and more rigorous commissioning processes. This advanced course is designed for working installers ready to move into the commercial sector.
Students will work on commercial training arrays, simulating real job-site conditions including OSHA safety protocols, crew communication, and production-pace installation workflows.
Course Modules
-
01
Commercial System Architectures
Central vs. string inverter topologies, DC-coupled battery storage, skid-mounted equipment, and utility-scale layout principles.
-
02
Ballasted & Ground-Mount Racking
Ballasted flat-roof systems, torque specs, wind uplift calculations, pile-driven ground-mount, and tracker systems overview.
-
03
Three-Phase Electrical & Transformers
Three-phase power theory, delta vs. wye configurations, medium-voltage transformers, and switchgear basics.
-
04
Utility Interconnection & Metering
Interconnection agreements, revenue-grade metering, net metering vs. buy-all/sell-all, and utility coordination processes.
-
05
Commissioning, Testing & Documentation
I-V curve tracing, thermal imaging, insulation resistance testing, combiner acceptance testing, and as-built documentation.
-
06
Commercial Site Safety
Construction safety certification, lock-out/tag-out, confined spaces, and commercial crew coordination.
What You'll Be Able to Do
Install ballasted commercial flat-roof racking
Wire three-phase combiner boxes, micro inverters and inverters
Execute a full system commissioning sequence
Interpret utility interconnection requirements
Conduct I-V curve tracing and thermal inspection
Lead a crew safely on a commercial job site
Prerequisites
Students should have completed the Residential Solar Installation course or have equivalent field experience (at least 6 months on a solar installation crew). Basic familiarity with three-phase electrical is helpful but not required; We cover it from the ground up.
