Residential Solar Solutions
Solar Panel Installation
Turn your roof into a power plant with a custom-designed system installed by accredited electricians.
Electricity bills are climbing while your roof sits unused. A properly sized solar system—matched to your usage, installed to code and connected to the grid—cuts your dependence on rising network tariffs. Solar Advice handles everything from roof inspection and system design through to grid connection paperwork, monitoring setup and handover.

Why your roof could power your home instead of paying rising network charges.
Electricity network tariffs have climbed faster than most household incomes, and that trend is not slowing. Your roof gets six to seven peak sun hours most days and generates power exactly when the grid is busiest—yet most homes leave that potential untapped. Battery storage has become cheaper, but a properly sized solar system starts paying for itself through bill reduction long before you add batteries.
A professional installation by an SAA-accredited electrician ensures your system is sized to match your consumption, installed to code and connected to the grid safely. You'll know the exact output you can expect, the rebates you qualify for, and how to monitor performance daily. Most systems reach payback in five to eight years and generate free power for another twenty.
What this covers
- 01
Site Assessment and Roof Inspection
We inspect your roof's condition, pitch, orientation and shading, test your switchboard and metering, and review your recent power bills to size the system correctly. A structural engineer's report is arranged if needed.
- 02
System Design and Modelling
We calculate the best array size for your usage, select tier-one panels and an inverter matched to your roof and power supply, and model your expected generation and bill savings. The design is shown to you in writing before any order is placed.
- 03
Installation and Connection
Our SAA-accredited electricians install your panels, inverter, racking, isolators and safety switches to Australian standards. We lodge grid connection paperwork with your distribution network and arrange the final network inspection and export approval.
- 04
Monitoring Setup and Handover
Your monitoring app is configured and tested, and you're shown how to read generation, export and daily savings. You receive a handover pack with performance data, warranty certificates and contact details for future support.
- 05
Battery Storage Integration
If you're adding a battery now or later, we design and install the system with battery-ready switchboard wiring and compatible inverter firmware. We can also help you apply for the Cheaper Home Batteries Program rebate.
How to choose the right system size for your home.
System size in kilowatts (kW) should match your average daily consumption. Review your last twelve months of power bills: most Australian homes use 15–25 kWh per day. A 6.6 kW system on a single-storey home typically generates 20–28 kWh per day depending on location and season; a 10 kW system on a double-storey home generates 30–42 kWh per day. High-usage households with air conditioning, pools or electric hot water may need 13 kW or larger.
Your installer will use your consumption data and your postcode's solar zone (which determines the STC multiplier under the SRES) to recommend the sweet spot: large enough to cut your bill significantly, but not so large that most output goes unused and exports to the grid for a lower feed-in tariff. Oversizing can reduce your return on investment; undersizing leaves potential on the table. The site assessment includes a written modelling report showing your expected generation month by month, your estimated bill savings and your payback timeline.
If you expect your usage to increase (for example, you're planning to add air conditioning or an electric vehicle), design the system to accommodate that growth. Many modern inverters can handle additional panels later without needing a complete redesign.
Roof type, pitch and orientation: how they affect your system.
Solar panels perform best on south-facing roofs in Australia between 15° and 40° pitch. Tile roofs (terracotta, concrete and Colorbond) are ideal because flashing (waterproofing boots) is well proven. Tin (corrugated metal), metal and fibre cement roofs are also suitable with proper racking and flashing. Flat roofs need weighted ballast racking instead of roof penetrations, which is more expensive but equally reliable.
If your roof faces north-west, east or west, you'll generate less midday power but more in afternoon and evening—useful if you use air conditioning late in the day or charge an electric vehicle after work. Shading from trees, buildings or terrain reduces output and should be mapped during the site assessment. If significant shading is unavoidable, we discuss options including partial shading (using microinverters or power optimisers on affected panels), repositioning arrays, or trimming vegetation with the owner's consent.
Multi-storey homes often have multiple roof planes at different angles. Your installer can split the array across two or three sections with separate inverters (or one three-phase inverter) if it improves output and future expansion options. Roof age and condition matter: if your roof will need replacement within five years, it's worth planning that work before or alongside your solar project to avoid disturbing the system later.
Pricing guide
How much does solar installation cost in Australia?
Total cost depends on system size (kW), panel and inverter brand tier, roof type and pitch, switchboard condition, single or three-phase supply, and available rebates. After accounting for Small-scale Technology Certificates (STCs) under the federal SRES, the net cost to you is typically 20–30% lower than the before-rebate price. Your distribution network, postcode and any state-specific incentives also influence the final figure.
- System size in kilowatts (kW) and number of panels
- Panel and inverter brand tier (tier-one vs. mid-tier)
- Roof type (tile, tin, metal, fibre cement) and pitch (15°–40° ideal)
- Switchboard condition and whether single or three-phase electrical supply
- Distance from switchboard to roof and cable run complexity
- Available rebates: STCs under federal SRES, state top-up schemes, and Cheaper Home Batteries Program for storage
| Job type | Low | Typical | High |
|---|---|---|---|
| 6.6 kW system, single-storey tile roof, south-facing | $4,000 | $5,200 | $6,500 |
| 10 kW system, double-storey home, mixed shading | $6,500 | $7,500 | $8,500 |
| 13 kW system, high-usage household, three-phase upgrade | $8,500 | $9,000 | $9,500 |
| Upgrade from 5 kW to 10 kW with new inverter and battery-ready wiring | $5,000 | $6,500 | $7,500 |
Prices shown are market guidance ranges in AUD and include GST. They are not promises. Final quotes vary by postcode, roof condition and retailer choice. Your installer will provide a detailed written quote after the site assessment. If you're adding a battery, expect an additional $8,000–$15,000 depending on capacity; the Cheaper Home Batteries Program subsidy (from 1 May 2026) reduces this by up to $12,600 for a 10 kWh system. Confirm current rebate amounts with the Clean Energy Regulator or your state energy agency.

Do not commit to an installation without a written site assessment, system design and itemised quote. Avoid quotes that do not clearly state system size (kW), panel and inverter model, roof orientation, expected generation (kWh/year) and your estimated net cost after rebates. If your roof is in poor condition, over twenty-five years old, or shows signs of structural movement, the installer will recommend a professional roof inspection before proceeding. Confirm your eligibility for STCs and any state rebates; some programs have income or postcode restrictions.
Questions to ask every installer
- 1Is your installer SAA accredited, and can you confirm their current accreditation number?
- 2Will you provide a written site assessment report and system design before I commit?
- 3How do you handle grid connection paperwork and communication with my distribution network?
- 4What warranty do you offer on the system as a whole, and what do the panel and inverter manufacturers cover?
- 5Can you provide references from customers with similar roof type and system size to mine?
Local solar data
How much power does solar make in Victoria?
Each kW of panels in Victoria makes about 1,366 kWh a year (Melbourne data). That means a 6.6kW system makes around 9,016 kWh a year, or about 25 kWh on an average day. Melbourne averages 4.8 peak sun hours a day.
Figures use PVWatts modelling for a north-facing (south-facing in the northern hemisphere) roof at 20°. Your actual output depends on shade, roof direction and the panels you choose.
