How to Price Solar Installations in Australia 2026: The Complete Guide for Solar Businesses
Getting your pricing right is the single most important financial decision a solar installation business makes. Underprice and you’re working hard for nothing — or worse, running at a loss without realising it. Overprice against competitors without a clear value proposition and you lose the job.
The solar market in Australia in 2026 is more competitive than it’s ever been. System prices have come down significantly over the past five years. Feed-in tariffs have dropped in most states. But installation costs — labour, compliance, insurance, vehicle running, admin — have gone up.
The installers who are winning in 2026 aren’t necessarily the cheapest. They’re the ones who know their numbers precisely, price confidently, and communicate value clearly. This guide walks through exactly how to build a solar installation pricing model that’s accurate, competitive, and profitable.
The Components of a Solar Installation Price
Every quote you send should recover five things:
- Direct material costs — panels, inverter, mounting hardware, cabling, isolators, switchboard components
- Labour costs — installer time on-site, travel, commissioning
- Compliance and certification costs — CER documentation, state electrical certificates, inspection fees
- Overhead allocation — your share of office, insurance, vehicle, admin, software, marketing costs
- Profit margin — your return on capital and risk
Most solar businesses price reasonably well on materials and labour, but badly underestimate compliance costs and overhead. That’s where margins get squeezed.
Step 1: Know Your True Labour Cost
Your labour cost is not your installer’s hourly wage. It’s the full cost of having that person employed, plus a share of the time that doesn’t generate revenue.
Calculating loaded labour cost
Base wage (e.g., licensed electrician, Electrical Award 2025-26): ~$38–$45/hour depending on level
Add on-costs:
- Superannuation (11.5%): ~$4.50–$5.20/hr
- Workers compensation insurance (electrical trade): ~$3–$5/hr (varies by state and claims history)
- Annual leave loading: ~$1.50–$2/hr
- Training, licensing, CPD: ~$1–$2/hr
Loaded hourly cost: ~$48–$60/hour for a licensed electrician
Now account for non-billable time. Your installer spends time on training, travel between jobs, equipment maintenance, admin, sick leave. In a typical solar business, utilisation (the proportion of paid hours that produce billable work) runs at 70–80%.
If your loaded cost is $55/hr and utilisation is 75%, your effective cost per billable hour is $55 ÷ 0.75 = $73/hr.
This is your minimum labour recovery rate — the rate at which you break even on labour before overheads and margin. It’s not your charge-out rate. Add overhead and margin on top.
Step 2: Materials Pricing
Solar equipment costs vary by supplier relationships, volume purchasing, and market timing. For 2026 pricing reference:
Residential 6.6kW system (typical IQ: 22x 300W panels, 5kW single-phase inverter):
- Panels (22 x premium Tier-1): $1,800–$2,800 depending on brand and supplier
- Inverter (5kW, premium brand): $900–$1,400
- Mounting hardware (railed system, residential): $400–$700
- DC cabling, isolators, surge protection: $250–$400
- AC connection hardware, switchboard components: $150–$300
- Monitoring hardware (if separate): $0–$200
Total equipment range: $3,500–$5,800 for a 6.6kW system
Mark-up on materials: Solar installers typically apply a 15–25% mark-up on materials. At 20% on $4,500 midpoint equipment = $900 materials margin.
Key principle: Don’t hide your material margin inside an opaque total price. Know it’s there, track it, and protect it when suppliers change pricing.
Step 3: Compliance and Certification Costs
This is the most consistently underestimated cost category.
Per-job compliance costs:
- CEC/CER documentation preparation: 30–60 min admin time
- State electrical certificate (CES in VIC, CCEW in NSW, CoTC in QLD): $0–$100 fee depending on state
- Network notification and connection forms: 30–60 min admin time
- STC lodgement process: 30–60 min (if doing in-house) or ~$100–$200 fee to STC trader
- AS/NZS 5033 documentation (string sizing calculations, labelling compliance): 15–30 min
Compliance cost per job: 1.5–3 hours admin/documentation time + certificate fees
At your loaded admin rate ($50–$70/hr equivalent), compliance adds $75–$200+ per job that many installers absorb into their margin without tracking.
If you’re using ServiceM8 with a compliance workflow built in, this time drops significantly — but it still needs to be recovered in pricing. Never treat compliance admin as a cost of doing business that doesn’t count.
Step 4: Overhead Recovery
Your overhead is everything that costs money but doesn’t directly install a panel. It needs to be recovered across your jobs.
Typical overhead categories for a small solar business:
| Category | Annual Cost Estimate |
|---|---|
| Vehicle (loan, rego, insurance, fuel, maintenance) | $15,000–$25,000/vehicle |
| Insurance (public liability, professional indemnity, tool, vehicle) | $6,000–$12,000 |
| Software (job management, accounting, design, CRM) | $3,000–$8,000 |
| Office / home office | $2,000–$6,000 |
| Marketing and advertising | $5,000–$20,000 |
| Accounting and bookkeeping | $3,000–$6,000 |
| Tools and equipment maintenance | $2,000–$5,000 |
| Owner’s salary and super | $80,000–$150,000 |
Total annual overhead (small operator, 1–2 vans): $120,000–$230,000
Jobs per year: A well-utilised 1-van solar business does 8–15 residential installs per month = 100–180 per year
Overhead per job: $120,000 ÷ 130 jobs = $923 per job (conservative)
Many installers have never calculated this number. They price based on materials + labour and wonder why the business doesn’t make money. If you’re not recovering at least $800–$1,200 in overhead per residential job, you’re subsidising every install from your own pocket.
Step 5: Profit Margin
After recovering all costs — materials, labour, compliance, overhead — your profit margin is the return on your capital, risk, and time as a business owner.
Industry benchmark: 10–20% net profit margin is healthy for a well-run solar installation business. Below 10% leaves you vulnerable to cost increases and provides no buffer for bad jobs. Above 20% is excellent and usually indicates strong repeat/referral business or premium positioning.
Calculate it on your fully-loaded cost, not just materials:
If a 6.6kW job costs you:
- Materials: $4,500
- Labour (6 hours at $73/hr effective): $438
- Compliance: $150
- Overhead allocation: $950
- Total cost: $6,038
At 15% net margin: Quote $6,038 ÷ (1 - 0.15) = $7,103
At 20% net margin: $6,038 ÷ 0.80 = $7,548
Real-World Pricing Reference: 2026 Australian Market
For context, average market pricing ranges for residential solar installation in 2026:
| System Size | Equipment Quality | Installed Price Range |
|---|---|---|
| 6.6kW (22 panels) | Standard Tier-1 | $6,500–$8,500 |
| 6.6kW (22 panels) | Premium (SunPower, Enphase) | $8,000–$12,000 |
| 10kW | Standard Tier-1 | $9,000–$13,000 |
| 13.2kW | Standard Tier-1 | $11,000–$16,000 |
| 6.6kW + 10kWh battery | Standard | $13,000–$18,000 |
| 6.6kW + 13.5kWh (Powerwall 3) | Tesla | $18,000–$24,000 |
STC offset: At the 2026 STC deeming period and current market price (~$35–$38 per STC), a 6.6kW system in zone 3 generates approximately $1,800–$2,200 in STC value. This is typically passed through to the customer as a point-of-sale discount. Make sure your quote shows the pre-STC price and the STC discount separately — this is a customer trust signal and also clarifies your actual revenue.
Pricing Strategy: How to Win at the Right Margin
The cheapest quote wins less than 30% of solar jobs in the current market, according to consistent industry surveys. Homeowners buying solar in 2026 are more educated — they’ve been stung by cheap installers, they read reviews, they check CEC accreditation.
What actually wins jobs:
- Fast quote turnaround (within 24 hours — use ServiceM8 quote automation)
- Professional quote presentation with clear breakdown
- Google reviews and social proof
- CEC accreditation prominently displayed
- Specific system design (shade analysis, consumption data review) rather than generic quote
- Clear warranty terms on labour and equipment
Price confidently. Know your numbers. And make it easy for customers to say yes with a professional, trust-building quote process.
Track Every Job to Refine Your Pricing
Your pricing model is a hypothesis until you track actual job profitability against estimates. Using ServiceM8’s job costing features, you can compare quoted time against actual time, see materials variance, and identify the job types where you consistently over or underestimate.
After 20–30 jobs with accurate tracking, your pricing model will be calibrated to your actual business — not industry averages that may not reflect your cost structure.
