Solar Power Installers & Suppliers New South Wales

Why invest in solar power in NSW?

New South Wales enjoys an average of more than 2,300 hours of sunshine a year, making photovoltaic generation a logical move for homeowners, developers and commercial property managers alike. Rising electricity tariffs and generous Small-scale Technology Certificates (STCs) mean most systems pay for themselves in five to seven years—often faster when paired with smart battery storage and time-of-use tariffs. A well-designed array can lift the NatHERS rating of a new build and improve resale value, while shrinking your carbon footprint.

System types and core components

Most residential and light-commercial projects revolve around grid-connected rooftop panels, but you will also encounter ground-mount, solar carports and off-grid hybrids in regional NSW. Beyond the panels themselves, you’ll need:

• Inverters—string, micro or hybrid—to convert DC into usable AC power.
• Mounting & racking engineered for high wind zones from Kiama to Coffs Harbour.
• Monitoring platforms to track generation and automate appliance scheduling.
• Batteries ranging from 5 kWh wall-mount units to containerised storage for agribusiness.

Quality components should be on the Clean Energy Council’s approved product list and installed by CEC-accredited professionals.

Choosing the right solar power installer & supplier

Accreditation is only the starting point. Compare:

• Portfolio depth—look for projects with similar roof materials, pitch and shading profile to yours.
• Warranty terms covering workmanship (at least 5 years) and product (12–25 years).
• Energy modelling—credible installers will provide a PVsyst or equivalent report showing yield, payback and degradation assumptions.
• After-sales service—ask how performance is monitored and how faults are resolved.

Compliance, rebates and approvals in NSW

Systems up to 10 kW generally qualify for STCs; larger arrays may claim Large-scale Generation Certificates. Your installer must notify the DNSP (Ausgrid, Endeavour or Essential Energy) before connection, and certain heritage zones require local council DA approval. If you’re integrating batteries above 5 kWh, your design must meet AS/NZS 5139 for fire safety. Reputable suppliers will bundle all paperwork so you can focus on savings, not red tape.

Collaborating with other trades

Solar rarely exists in isolation. Depending on your build or renovation, you may also need:

• licensed electricians for switchboard upgrades.
• roofing contractors to replace old tiles or corrugated sheets.
• insulation installers to boost whole-of-home efficiency.
• commercial & specialist contractors for large-scale solar carports.
• plumbers & gas fitters when pairing PV with solar hot-water boosters.
• painters for reflective roof coatings that lower panel temperature.
• metal fabricators to custom-build racking on tricky sites.
• plasterers & renderers to repair internal ceilings after cable runs.
• waterproofers for flat concrete roofs.
• garage door professionals integrating smart charging for EVs.
• scaffolders to provide roof access on multi-storey sites.
• stonemasons and bricklayers for inverter pedestal plinths.
• interior lining installers to conceal conduit.
• tilers when re-sealing penetrations.
• building material suppliers for batten, flashing and fixings.
• building waste removal to dispose of packaging.
• cladding professionals if façade-integrated PV is on your wish list.
• construction equipment suppliers for cherry pickers and safety gear.
• lift contractors in high-rise retrofits.
• parking designers creating solar-shaded carparks.
• staircase builders for rooftop access stairs.
• balustrade contractors to meet edge-protection rules.
• window & door specialists when upgrading to double-glazing alongside PV.
• prefabricated building suppliers for modular switch rooms.
• demolition contractors clearing old structures before a ground-mount array.
• excavating contractors trenching for underground cabling.
• joiners crafting battery cabinetry that matches your interiors.

Project timeline & budgeting

A typical 6.6 kW residential installation in NSW unfolds over six to eight weeks: one week for design and approvals, two weeks for component ordering, a day or two on site for installation, and four weeks for DNSP paperwork and meter changeover. Expect turnkey pricing between $5,500 and $9,000, depending on panel efficiency, inverter brand and roof complexity. Commercial arrays start around $1,000 per kW installed, with economies of scale above 50 kW.
