Install solar PV panels and mounting

This unit covers mounting solar PV panels and arrays safely and to specification on a range of roof and ground structures.

Elements & performance criteria

1. Prepare the mounting structure

1.1 Mounting type is selected for the structure and array. [range: A]
1.2 Fixings are installed to the manufacturer's specification.
1.3 Structure is checked for level and load before panels are fitted.

2. Mount and secure panels

2.1 Panels are positioned for orientation and tilt per the design. [range: B]
2.2 Panels are secured and torqued to specification.
2.3 Array is bonded and earthed correctly.

Range

A. Mounting type: Roof rail; Tile hook; Ground frame; Pole mount

B. Array configuration: Single string; Multi-string; Portrait; Landscape

Evidence guide

Critical aspects: Candidate must mount a compliant, correctly bonded array on more than one occasion, in a real or realistically simulated working environment.

Underpinning knowledge

Solar irradiance and the effect of orientation and tilt on yield.
Roof and structural load considerations for arrays.
Bonding, earthing, and lightning protection principles.
Manufacturer mounting and torque specifications.

Assessment methods: Observation, Product inspection, Oral questioning

On the job where possible; off-the-job assessment requires a realistic rig. Candidate must have access to tools, fixings, and the relevant specifications.
