Solar Installation in Australia: The Boom Trade of 2026
Australia has more rooftop solar per capita than any other country on Earth. Over 4.3 million homes — roughly one in three — now have solar panels on the roof. Battery storage installations have surged by over 190% since 2022. The electric vehicle charger market is growing at 21% annually and expected to reach $1.69 billion by 2028.
For electricians and solar installers, this is the opportunity of a generation. The solar and clean energy sector is creating more work, at higher margins, with stronger demand, than almost any other segment of the Australian trades. And the growth is not slowing down — it is accelerating.
This article covers the full picture: the market data, the career and business opportunity, the qualifications you need, and how to position yourself for the decade ahead.
The Market: By the Numbers
Rooftop Solar
| Metric | Value (2026) |
|---|---|
| Homes with rooftop solar | 4.3 million+ |
| Penetration rate | 1 in 3 Australian homes |
| New installations per year | ~350,000 |
| Average system size (residential) | 8 – 10 kW |
| Average installation cost (6.6kW system) | $5,500 – $8,500 (after rebates) |
| Average installation cost (10kW system) | $8,000 – $13,000 (after rebates) |
| Total annual market value (residential solar) | ~$3 billion |
| Commercial solar installations per year | ~15,000+ |
Australia's solar installations have been growing at 10–15% year-on-year, and the market shows no signs of saturation. The average system size continues to increase as homeowners add more panels to power EVs, batteries, and all-electric homes. Repowering (upgrading older, smaller systems) is also emerging as a significant segment.
Battery Storage
| Metric | Value (2026) |
|---|---|
| Annual residential battery installations | ~50,000+ |
| Growth rate | 30 – 40% year-on-year |
| Average residential battery cost (installed) | $10,000 – $18,000 (10–13.5kWh) |
| Popular brands | Tesla Powerwall 3, BYD HVS, Sungrow SBR, Enphase 5P |
| Total annual market value (residential batteries) | ~$750 million+ |
| Average installer margin on battery work | 15% – 25% |
Battery storage is the fastest-growing segment in the residential solar market. The combination of rising electricity prices (averaging 33c/kWh nationally in 2026), declining battery costs, and time-of-use tariffs makes batteries an increasingly compelling financial proposition for homeowners with existing solar systems.
Tip: Battery retrofits — adding a battery to an existing solar system — represent a huge opportunity. Of the 4.3 million homes with solar, less than 15% have a battery. That is a potential market of over 3.5 million homes. If you are a solar installer, make sure you are offering battery additions to every existing solar customer in your area.
EV Chargers
| Metric | Value (2026) |
|---|---|
| Electric vehicles on Australian roads | ~500,000+ |
| New EV sales per year | ~200,000+ (25% of new car sales) |
| Annual home EV charger installations | ~120,000+ |
| Average home charger installation cost | $1,500 – $3,000 |
| Average commercial charger installation cost | $5,000 – $25,000 |
| Market growth rate | 20 – 25% annually |
| Total EV charger market value | ~$1.2 billion |
Every EV needs a charger. While EVs can charge from a standard 10-amp power point, most owners install a dedicated 7kW or 22kW wall-mounted charger for faster, safer, and more convenient charging. This requires a licensed electrician for installation — dedicated circuit, switchboard work, and often a solar integration discussion.
Heat Pump Hot Water
| Metric | Value (2026) |
|---|---|
| Annual heat pump installations | ~150,000+ |
| Growth rate | 25 – 35% year-on-year |
| Average installed cost | $2,500 – $4,500 (before rebates) |
| Government rebates available | Up to $1,000 in most states |
| Electrician involvement | Electrical connection required for all units |
Heat pump hot water systems are the fastest-growing hot water technology in Australia, driven by NCC 2025 energy efficiency requirements, government rebates, and the push to replace gas with electric. Every installation requires electrical work, making this a natural add-on service for electricians and solar installers.
The Career Opportunity
Entry Paths
There are two main paths into solar installation:
| Path | Requirements | Timeline |
|---|---|---|
| Qualified electrician → solar endorsement | Complete Certificate III in Electrotechnology (4-year apprenticeship), then add solar-specific qualifications | 4 years (apprenticeship) + 1–2 weeks (solar training) |
| Clean Energy Council (CEC) accredited installer | Must be a licensed electrician; complete CEC-approved training; apply for CEC accreditation | 1 – 3 months (for qualified electricians) |
Important: In Australia, you must be a licensed electrician to perform the electrical work associated with solar installation. A solar-specific qualification alone is not sufficient — the electrical licence is the foundation. CEC accreditation is then added on top, which allows you to design and install systems eligible for Small-scale Technology Certificates (STCs) — the federal solar rebate.
Qualifications Required
| Qualification | What It Covers | Where to Get It |
|---|---|---|
| Certificate III in Electrotechnology Electrician (UEE30820) | Full electrical trade qualification | TAFE / RTO (4-year apprenticeship) |
| Grid-connected PV system design and install (UEERE5001A) | Solar panel system design, installation, and commissioning | CEC-approved training providers (1 – 2 weeks) |
| Battery storage installation (UEERE5002A) | Battery system design, installation, and commissioning | CEC-approved training providers (1 – 3 days) |
| CEC Accredited Installer | Design and install solar/battery systems eligible for STCs | Clean Energy Council (annual renewal) |
| ARC licence (if handling refrigerant for heat pumps) | Refrigerant handling for heat pump installation | Australian Refrigeration Council |
Tip: CEC accreditation is not just a nice-to-have — it is commercially essential. Only CEC-accredited installers can create STCs (the federal solar rebate), which reduce the upfront cost of a solar system by $2,000–$4,000 for the customer. Without CEC accreditation, you cannot offer this rebate, which makes your pricing uncompetitive against accredited installers.
Earnings Potential
Employee Roles
| Role | Annual Salary |
|---|---|
| Solar installer (labourer, non-electrical) | $55,000 – $75,000 |
| Solar electrician (licensed, employee) | $80,000 – $110,000 |
| Senior solar electrician / team leader | $100,000 – $130,000 |
| Solar system designer | $75,000 – $95,000 |
| Sales / design consultant | $70,000 – $120,000 (base + commission) |
Self-Employed / Business Owner
| Business Model | Annual Revenue | Owner Take-Home |
|---|---|---|
| Sole trader (2 – 3 installations per week) | $200,000 – $400,000 | $100,000 – $180,000 |
| Small team (2 – 3 installers + labourers) | $500,000 – $1,500,000 | $150,000 – $300,000 |
| Established business (5+ teams) | $2,000,000+ | $250,000+ |
Per-Job Profit Margins
| Job Type | Typical Customer Price | Installer Cost (panels, inverter, materials, labour) | Gross Margin |
|---|---|---|---|
| 6.6kW residential solar | $5,500 – $8,500 | $3,500 – $5,500 | 30% – 40% |
| 10kW residential solar | $8,000 – $13,000 | $5,500 – $8,000 | 30% – 40% |
| 13.5kWh battery add-on (e.g., Tesla Powerwall) | $12,000 – $16,000 | $9,000 – $12,000 | 20% – 30% |
| Home EV charger installation | $1,500 – $3,000 | $600 – $1,200 | 50% – 60% |
| Commercial solar (30kW) | $25,000 – $40,000 | $16,000 – $26,000 | 30% – 40% |
EV charger installations have the highest margin on a percentage basis because the labour component is high relative to materials. A $2,000 charger installation might take 2–3 hours at a material cost of $800 — giving you an effective hourly rate of $350–$400.
The Growth Drivers
Government Policy
| Policy | Impact |
|---|---|
| Renewable Energy Target (RET) | Sustained demand for renewable installations |
| Small-scale Renewable Energy Scheme (SRES) | STC rebates reduce customer cost by $2,000–$4,000 |
| NCC 2025 (whole-of-home energy budget) | Solar effectively required on many new builds |
| State rebates (VIC, NSW, SA, QLD, ACT) | Additional rebates up to $1,400 on solar, $2,000+ on batteries |
| Emission reduction targets (43% by 2030) | Long-term policy certainty for renewable investment |
| EV incentives (FBT exemption, stamp duty discounts) | Accelerating EV adoption → more charger demand |
Economic Drivers
| Driver | Impact on Solar Demand |
|---|---|
| Electricity prices (33c/kWh average, up from 25c in 2022) | Stronger financial case for solar; faster payback |
| Feed-in tariffs declining (now 3–8c/kWh in most states) | Drives battery adoption (store and use, rather than export) |
| Time-of-use tariffs | Peak electricity costs 40–55c/kWh, making solar + battery highly valuable |
| Rising home values | Solar and battery add $15,000–$30,000 to property value |
Technology Trends
| Trend | What It Means for Installers |
|---|---|
| Larger panel wattages (450W–600W per panel) | Fewer panels per system = faster installation |
| Hybrid inverters | Simplify battery retrofit; one device for solar + battery |
| Virtual power plants (VPP) | New revenue model — batteries earn money for homeowners by feeding grid during peak |
| Microinverters and optimisers (Enphase, SolarEdge) | Higher per-panel cost but better performance and monitoring |
| Integrated solar + battery + EV charger systems | One installer, one visit, one customer relationship |
Tip: The most successful solar businesses in 2026 are those offering the full package: solar panels, battery storage, EV charger, and whole-of-home energy management. Customers want one trusted provider, not three separate tradies. If you can design and install the complete energy system, you capture more revenue per customer and build stronger relationships.
Starting a Solar Installation Business
Startup Costs
| Item | Cost |
|---|---|
| Electrical contractor licence + CEC accreditation | $500 – $2,000 |
| Public liability insurance ($20M) | $2,500 – $5,000/year |
| Work vehicle (van or ute with racks) | $30,000 – $55,000 |

| General electrical tools | $5,000 – $15,000 |
| Software (design software, quoting, accounting) | $100 – $300/month |
| Marketing (website, Google ads, signage) | $2,000 – $5,000 (initial) |
| Initial stock / materials | $5,000 – $10,000 (first batch of panels, inverters) |
| Total startup investment | $50,000 – $100,000 |
Key Business Considerations
Supplier relationships matter. Solar panels and inverters are commodity products with tight margins. Building strong relationships with distributors (OneStop Warehouse, Raystech, Solar Juice, Supply Partners) gives you better pricing, priority stock allocation, and faster delivery. This directly affects your competitiveness and margins.
Warranty obligations are long. Solar panels carry 25-year warranties. Inverters carry 10–15-year warranties. You are responsible for the workmanship warranty (typically 5–10 years). Make sure your business is structured to honour these commitments, and factor warranty service into your pricing.
Seasonality is moderate. Solar installations peak in spring and autumn (cooler weather, homeowners preparing for summer electricity bills or post-summer regret). Winter is slower but manageable. Summer can be limited by extreme heat (unsafe for roof work above 35 degrees).
The Competitive Landscape
The solar installation market in Australia is competitive, with over 7,000 CEC-accredited installers nationally. However, the quality varies enormously, and there is significant room for well-run businesses to differentiate on quality, service, and professionalism.
| Competitor Type | Strength | Weakness |
|---|---|---|
| Large national companies (e.g., Sungrow, SolarEdge partners) | Scale, brand recognition, marketing budget | Often use subcontractors; inconsistent quality |
| Online aggregators (e.g., SolarQuotes) | Lead generation, price comparison | You compete on price; lower margins |
| Local independents (your direct competitors) | Local reputation, personal service | Variable quality and professionalism |
How to differentiate:
- Quality installations with proper documentation. Photos, compliance certificates, system monitoring setup, and a professional handover process.
- After-sales service. Annual system health checks, monitoring alerts, and responsive warranty service. The big companies are terrible at after-sales — this is where you win.
- Whole-of-home energy solutions. Solar + battery + EV charger + energy management. One provider, one relationship.
- Speed and professionalism. Professional quotes within 24 hours. Installation within 2 weeks of acceptance. Communication throughout. These basics are rare in the solar industry.
- Local reputation. Google reviews, local community presence, and word of mouth. In solar, most customers still choose their installer based on trust and reputation, not price.
