Solar Installation Guide for Electricians

Solar installation represents one of the fastest-growing opportunities for electricians. With government incentives, falling equipment costs, and increasing environmental awareness, more homeowners and businesses are installing solar systems than ever before. This guide covers everything you need to know to add solar to your service offering.

Why Add Solar to Your Business?

• Growing demand: Solar installations are increasing year over year
• Higher margins: Solar jobs typically have higher ticket values than standard electrical work
• Future-proofing: Renewable energy is the future of electricity
• Government incentives: Various rebates and incentives support solar adoption
• Diversification: Adds a new revenue stream to your business

What You Need to Know

Solar installation involves several components that go beyond standard electrical work:

• DC systems: Solar panels produce DC power, which must be safely handled
• Inverters: Converting DC to AC power for home use
• Battery storage: Optional but increasingly popular
• Grid connection: Feeding power back to the grid
• Roof mounting: Structural considerations and waterproofing
• System sizing: Calculating appropriate system sizes

Required Training and Certifications

Australia

• Licensed electrician (mandatory)
• Grid-connected PV systems accreditation through the Clean Energy Council
• Design and Install endorsements
• Battery storage accreditation (if installing batteries)

New Zealand

• Registered electrician (mandatory)
• Electrical service technician or electrical engineer registration
• Solar-specific training through providers like SolarNZ
• Worksafe certification for working at heights

Training Path

1. Complete prerequisite electrical license/registration
2. Complete solar PV design and installation course (typically 3-5 days)
3. Gain practical experience (work with experienced installer)
4. Apply for accreditation/certification
5. Stay current with continuing education

Equipment and Tools Needed

Additional Tools

• DC cable crimping tools
• Solar panel lifting equipment
• Roof anchor points and safety equipment
• Irradiance meter (for system testing)
• Thermal camera (optional, for diagnostics)
• Fall protection equipment

Vehicle Requirements

You'll need transport for:

• Solar panels (typically 1.6m x 1m each)
• Inverters (15-30kg)
• Batteries (if applicable, can be 100kg+)
• Rails and mounting hardware

Types of Solar Installations

Residential Grid-Connect

The most common type. Systems typically range from 3kW to 10kW.

• Relatively straightforward installation
• Standard roof mounts
• Grid-tie inverters
• May include battery storage

Commercial Installations

Larger systems for businesses, typically 10kW to 100kW+.

• More complex electrical requirements
• May require switchboard upgrades
• Three-phase connections
• Commercial-grade inverters

Off-Grid Systems

Standalone systems not connected to the grid.

• Battery storage essential
• Backup generators often included
• More complex system design
• Requires thorough energy audit

The Installation Process

1. Site assessment: Roof condition, orientation, shading analysis
2. System design: Size system to match energy needs and roof space
3. Quote and approval: Present proposal, obtain customer approval
4. Permits and approvals: Grid connection approval, council permits if needed
5. Installation: Mount panels, install inverter, connect to switchboard
6. Testing and commissioning: Verify system performance, test safety systems
7. Documentation: Provide certificates, warranties, and handover

Safety Considerations

• Working at heights: Proper fall protection essential
• DC voltage hazards: Solar panels produce voltage even in low light
• Roof integrity: Ensure roof can support panels
• Weather: Don't install in wet or windy conditions
• Isolation: Proper procedures for isolating DC systems
