Objectives
After completing this practical activity, learners will be able to:
- Install grid-tied Solar PV structural systems according to workplace operational standards
- Install AC and DC PV components safely
- Apply cable routing and component positioning procedures
- Verify installation quality and structural stability
- Apply workplace electrical and operational safety procedures during installation activities
Scenario
You are part of a solar PV installation team responsible for installing the structural, AC, and DC components of a grid-tied Solar PV system. Before the grid-tied system can be commissioned, all mounting systems, AC and DC components, distribution systems, and support structures must be installed and secured according to workplace operational standards and manufacturer specifications.
You are required to install the systems safely while ensuring operational compliance, structural stability, and workplace safety.
