Where’s the job?

Overview

• Installing solar PV panels and associated inverter systems on rooftops or ground mounts to harness renewable energy and maximise electric feed-in tariff benefits.

• Skill level: 4 / 5 (detailed design, secure mounting, electrical wiring and grid compliance are essential).

• Typical duration: 1 – 3 days based on roof complexity, system size and regulatory approvals.

Safety First

• Secure all ladders and use fall protection when working at heights.

• Isolate and double-check electrical supplies before commencing wiring and inverter installation.

• Comply with local electrical regulations, ensuring all components are RCD-protected.

• Handle PV panels carefully to avoid damage; retain manufacturer guidance for mounting and cleaning.

• For grid connections, ensure safe separations and proper earthing.

Tools & Materials

Step-by-Step

1. Assess the site – evaluate roof orientation, shading and structural integrity for optimal panel placement.

2. Design the layout – plan the array configuration and system capacity based on energy needs and available space.

3. Install mounting brackets – secure them to the roof or ground structure ensuring proper clearance and alignment.

4. Fix the PV panels – attach the panels to the mounting system following manufacturer guidelines.

5. Electrical connections – wire the panels in series or parallel, connect to the inverter and install necessary RCD devices.

6. Commissioning – perform inverter tests, synchronise with the grid and register for the electric feed-in tariff.

7. Final checks – inspect all connections, ensure proper earthing and complete documentation for feed-in tariff approval.

Completion Checks

• Inverter displays normal operation and synchronises with the grid.

• Solar power generation is consistent with the design output and feed-in tariff data is recorded.

• All electrical connections are secure, safe and documented.

• The system has passed final inspections and is ready for utility metering.

When to Call a Pro Instead

If the installation involves complex roof work, structural modifications or intricate grid connection procedures, a certified solar installer or NICEIC-registered electrician will ensure compliance with regulations and guarantee system longevity.
