Thinking about starting a solar panels business in Australia? You’re in the right place. Demand for residential and commercial solar is strong, technology costs continue to fall, and customer awareness of energy bills and sustainability is only increasing.
But building a successful solar business takes more than technical know‑how. You’ll need the right business structure, clear contracts, strong compliance with Australian Consumer Law, and day‑to‑day practices that protect your brand and cash flow.
In this guide, we’ll walk you through how to set up a solar panels business the right way - from planning and registrations to essential legal documents and ongoing compliance. If you follow these steps, you’ll be in a great position to win work and grow with confidence.
What Does A Solar Panels Business Do?
When we talk about a “solar panels business” here, we’re looking broadly at businesses that sell, design, supply, install and/or maintain solar photovoltaic (PV) systems for homes and businesses. Many operators also offer batteries, inverters, EV chargers and ongoing maintenance or monitoring services.
There are a few common models you might adopt:
- Design and install: You quote, supply and install systems end‑to‑end (often the most common model).
- Supply only: You sell equipment to builders, electricians or DIY customers (e.g. online sales with delivery).
- Commercial projects: Larger arrays for businesses, schools or strata, often with more complex contracts and approvals.
- Service and maintenance: Health checks, cleaning, warranty claims and upgrades for existing systems.
Your legal setup will need to match the model you choose - especially your customer terms, supplier contracts and warranties.
Is A Solar Panels Business Profitable?
It can be, with the right plan. Profitability depends on your target market, margins on equipment, installation efficiency, and after‑sales service. Before you invest, build a simple business plan and stress‑test your assumptions.
Key areas to consider in your plan:
- Target customers and location: Are you focusing on homeowners, small businesses, new builds, or retrofits?
- Services and pricing: Will you offer supply and install, or supply‑only? Will you offer finance or “solar as a service”?
- Suppliers and logistics: Who will supply panels, inverters and batteries? What lead times and credit terms apply?
- Capability and resourcing: Will you use in‑house electricians or subcontractors? How will you schedule jobs?
- Legal and compliance: Licences, accreditations, consumer guarantees, and safety requirements.
- Cash flow and risk: Deposits, staged payments, and processes for warranty claims and chargebacks.
Documenting these details will guide your launch and help ensure your legal documents and processes fit your business from day one.
Step‑By‑Step: Setting Up Your Solar Panels Business
1) Research Your Market And Map Your Services
Start with your local market. Who’s installing solar in your area now, and what are their price points and offerings? Decide what you will sell (e.g. 6.6kW residential packages, small commercial systems, battery add‑ons) and how you’ll deliver it (in‑house team vs subcontractors). This clarity flows directly into your quotes, contracts and compliance plan.
2) Choose A Business Structure
Your structure affects liability, tax, and how you bring in co‑founders or investors. Common options are:
- Sole trader: Simple and low‑cost to start, but no separation between you and the business (you’re personally liable).
- Partnership: Easy to form with another person, but partners can be jointly liable for debts.
- Company: A separate legal entity that can offer limited liability and is often preferred for businesses taking on staff, larger projects or finance.
If you plan to grow, many owners opt for a company. You’ll also need an ABN, and if you use a trading name, register a business name that aligns with your brand.
3) Register Essentials (ABN, GST, Business Name)
Register for an ABN and consider GST registration (mandatory once you hit the $75,000 turnover threshold). If you operate under a trading name, make sure your business name is registered and appears correctly on quotes, invoices and your website.
4) Licences, Accreditation And Technical Compliance
Solar involves electrical work, so licensing and accreditation are critical. In most cases, solar PV installations must be performed by or under the supervision of a licensed electrician, and system designers/installers typically hold Clean Energy Council (CEC) accreditation for eligibility under government programs.
Requirements vary by state and territory (for example, electrical contractor licences and compliance certificates). Check your local regulator for details and ensure your site paperwork, compliance certificates and commissioning reports are built into your workflow.
5) Insurance, Safety And Site Risk
Work health and safety obligations apply to your team and contractors. Have safe work method statements, PPE processes, ladder and roof safety procedures, and incident reporting in place. It’s also prudent to speak with an insurer about public liability, product liability and professional indemnity cover that suits your services and contract terms.
6) Lock In Suppliers And Standardise Your Quotes
Secure supply lines for panels, inverters and mounting hardware, and standardise your quoting process. Clear inclusions, exclusions and lead times reduce disputes. Well‑drafted terms also let you stage payments (e.g. deposit, progress, practical completion) and clarify who handles meter changes and grid approvals.
7) Put Your Core Contracts And Policies In Place
Before your first job, get your customer terms, subcontractor agreements and warranties sorted. This is where you set expectations, manage risk and demonstrate professionalism. For installation work, many businesses use an Electrical Service Agreement tailored to solar quoting, installation milestones and commissioning.
What Laws Do You Need To Follow?
Beyond technical accreditation and electrical rules, several national laws apply to how you sell, promote and deliver your solar services. Here are the key areas to factor into your setup.
Australian Consumer Law (ACL)
The ACL sets rules around sales practices, consumer guarantees and refunds. Claims about performance, bill savings and payback periods must be accurate and not misleading. Standard form consumer contracts should avoid unfair terms. If your team sells door‑to‑door or by phone, unsolicited sales rules can apply.
It’s wise to review your sales scripts, ads, and customer terms with the Australian Consumer Law in mind to prevent disputes and penalties.
Warranties And Product Guarantees
Panels, inverters and batteries carry manufacturer warranties, and you also provide consumer guarantees under the ACL for your services (e.g. due care and skill). If you offer your own “workmanship warranty,” ensure it is clear, compliant and easy for customers to use. Many businesses document this in a concise Warranties Against Defects Policy provided with the contract and completion paperwork.
Marketing And Environmental Claims
Be careful with “green” and savings claims. Promises like “zero bill” or a specific payback period need a reasonable basis. Keep backup calculations and disclaimers consistent with your actual systems and site assumptions. Misleading environmental claims can breach the ACL.
Privacy And Direct Marketing
If you collect customer data through your website, quote forms or CRM, you’ll need clear notices and secure handling practices. Most solar businesses will need a Privacy Policy, and if you run email or SMS marketing, ensure you have consent and opt‑out mechanisms built in.
Employment, Contractors And Safety
If you hire staff, you’ll need compliant employment contracts, correct pay and entitlements, and a safe system of work. Many solar operators use subcontractors for installs or electrical work - that’s common, but it’s important to use a proper Contractors Agreement and avoid arrangements that could be considered sham contracting. Keep site safety responsibilities clear across your team and any subcontractors.
Building And Electrical Rules
State electrical safety laws, grid connection requirements and distributor approvals apply to installations. Incorporate these steps into your job flow (pre‑approval, metering changes, commissioning, and submission of compliance certificates). Retain records in case of audits or warranty claims.
What Legal Documents Will You Need?
The right contracts and policies will reduce risk, save time on each job, and give customers confidence. Not every business needs the same suite of documents, but many solar operators rely on the following.
- Customer Agreement (Supply & Install): Sets out scope, inclusions/exclusions, pricing, payment milestones, change requests, access to site, commissioning, and handover. Many businesses adapt an Electrical Service Agreement for solar projects and use it as their standard form contract.
- Supply Agreement: If you buy gear from wholesalers or importers, a written Supply Agreement clarifies delivery timeframes, risk, quality, credits/returns and warranty support.
- Warranties Against Defects Policy: A concise document given to customers explaining how to claim workmanship warranties, timeframes and who to contact. A compliant Warranties Against Defects Policy also helps align your promises with ACL guarantees.
- Website Terms & Conditions: If you publish product info, calculators or accept bookings online, Website Terms and Conditions set rules for use, disclaimers and IP protection.
- Privacy Policy: If you collect personal information (website enquiries, quotes, marketing lists), your Privacy Policy explains what you collect, how you use it, and how customers can contact you.
- Contractors Agreement: For subcontract installers and electricians, a clear Contractors Agreement sets rates, scope, safety obligations, IP, confidentiality and defect rectification.
- Terms of Trade/Quote Terms: Your quote and terms should work together to capture deposits, stage payments, variations, and cancellation fees in a way that’s fair and enforceable.
- Purchase Order/Procurement Terms: Helps standardise your orders with wholesalers or OEMs to avoid surprises on price changes or backorders.
- Service & Maintenance Agreement: If you offer ongoing servicing, it should cover response times, inclusions, exclusions, and any call‑out fees.
- Shareholders Agreement (if you have co‑founders): Sets out ownership, decision‑making, roles, bringing in investors and what happens if someone leaves.
You might also consider finance‑related protections where appropriate, such as reserving title in equipment until full payment is received or requiring a security if you offer extended credit. In some cases, businesses back this with a general security interest registered on the PPSR (speak with a lawyer about using a suitable form, such as a general security agreement, and the process to register an interest).
How Should You Handle Quotes, Deposits And Variations?
Clear proposals and quote terms are essential. In solar, jobs can change when site conditions differ or owners decide to add a battery. Your quotes should outline:
- How long the quote is valid, and what triggers a revision (e.g. site changes, roof condition, switchboard upgrades).
- Deposit amount and when progress and completion payments are due.
- What is included (e.g. metering change requests) and what is not (e.g. switchboard replacement unless explicitly quoted).
- How you will handle delays due to weather, supply chain issues or distributor approvals.
- Warranty support process and who handles manufacturer claims.
Getting these points into your standard contract reduces disputes and speeds up cash flow.
Selling Online? Don’t Forget Your Website Legal Pack
If you take enquiries or sell equipment online, put a basic “website legal pack” in place. At minimum, that’s your Privacy Policy and Website Terms and Conditions. If you sell products directly online, add clear delivery, pricing, returns and warranty terms (aligned with the ACL and your manufacturer processes).
If you publish performance calculators or savings estimates, include sensible disclaimers and ensure they reflect realistic, verifiable assumptions. This helps you avoid misleading representations and sets fair expectations before you step on site.
Working With Suppliers And Manufacturers
Strong supplier relationships keep your projects on schedule. A written Supply Agreement can set service levels for delivery, packaging, DOA procedures, RMA handling and who covers freight for returns. It should also address recalls, product changes and what happens if a line is discontinued mid‑project.
For higher‑volume accounts, consider negotiated pricing tiers or rebates, and ensure your contract documents how and when rebates are calculated and paid.
Using Subcontractors For Installation?
Many solar businesses scale by engaging qualified contractors for installation work. That can work well, provided you have a clear Contractors Agreement covering safety obligations, licencing, workmanship expectations, rectification of defects, and IP/confidentiality. Clarify who handles customer communication on site and how variations are authorised (and priced) to avoid confusion.
Also keep an eye on shifting worker classification rules. Ensure your contractor model is genuine and that you’re meeting Fair Work obligations if you also have employees.
Buying A Solar Business Or Joining A Franchise?
If you’d prefer not to start from scratch, you might buy an existing book of customers or join a franchise. Buying a business means careful due diligence on contracts, liabilities, brand assets, warranties, supplier terms and open defects or complaints. Have a lawyer review the sale contract and any assignment of customer and supplier agreements.
Franchising can offer brand recognition and systems, but you’ll need to review the franchise agreement, disclosure document, fees and territory rules carefully, and understand your rights and obligations under the Franchising Code of Conduct. Pay close attention to marketing claims, local licence requirements and who bears responsibility for warranty callbacks and service levels in your area.
Common Pitfalls To Avoid
- Overpromising on performance or bill savings in ads or quotes without a reasonable basis.
- Relying on handshake deals with suppliers or subcontractors - undocumented terms often lead to disputes.
- Unclear scope in quotes, leading to unpaid variations or unrealistic customer expectations.
- Missing key notices in warranty documents (ACL requires specific wording/clauses in certain cases).
- Collecting customer data without a compliant privacy notice or secure handling practices.
Addressing these early with the right documents and processes will save time, money and reputation later.
