With electricity prices continuing to rise across Victoria, more homeowners are considering switching to solar to power their appliances—especially energy-hungry systems like air conditioners. But before installing solar panels, one important question remains:

Is your home suitable for solar installation?

Not every home meets the ideal conditions for efficient solar production, but the good news is that most Melbourne properties can still benefit significantly from solar technology.
In this guide, Melbourne Aircon Specialist explains everything you need to check before going solar—so you can make a confident, cost-effective decision.

1. Does Your Roof Receive Enough Sunlight?

Solar panels thrive on sunlight, and the more direct sun your roof receives, the better the system will perform.

✔ Ideal Roof Directions for Melbourne:

• North-facing – Best performance year-round
• North-west or north-east – Excellent for afternoon or morning production
• East or West – Still viable, but slightly reduced output
• South-facing – Works, but not recommended unless no other option is available

Even if your home does not have a perfect north-facing roof, modern solar panels are efficient enough to still generate good savings.

---

2. Do You Have Enough Roof Space?

Solar panels require adequate surface area.
On average:

• A 6.6 kW system needs around 30–34 m²
• Larger systems (8–10 kW) need 40–60 m²

Things that can limit usable roof area:

• Skylights
• Chimneys
• Antennas
• Hip-style roofs with many angles

If space is limited, high-efficiency panels can help you achieve strong output in a smaller area.

3. Check for Shading Issues

Shading is one of the biggest factors affecting solar performance.

Common shading sources include:

• Trees
• Neighboring houses
• Double-story roofs
• Nearby buildings

Even partial shading can reduce energy production.
However, newer technologies like micro-inverters or optimisers can minimise shading losses.

4. Roof Condition & Material

Before installing solar, you must ensure your roof is in good condition.

✔ Suitable roofing types:

• Tile roofs
• Colourbond/metal roofs
• Tin and steel roofs
• Flat roofs (with tilt frames)

✔ Roof concerns to address first:

• Cracked or broken tiles
• Rusted metal sheets
• Structural issues
• Roofing nearing replacement age

If your roof needs repair in the next 2–5 years, it’s better to fix it before installing solar.

5. Check Your Switchboard Compatibility

Many Victorian homes require minor electrical upgrades before installing solar—especially older switchboards.

You may need:

• A main switch upgrade
• RCBOs or compliant safety switches
• Space for a solar main switch

Melbourne Aircon Specialist can assess your switchboard and advise if upgrades are needed.

---

6. Is Your Home Single-Phase or Three-Phase?

This affects system size.

Single-phase homes

Usually support up to 6.6 kW without export limitations (depending on distributor).

Three-phase homes

Can support larger systems such as 10 kW or more, ideal for homes with:

• Ducted air conditioning
• Electric vehicles
• Pools
• High energy consumption

Three-phase homes generally allow better solar flexibility and stability.

---

7. Your Household’s Energy Usage Pattern

Solar is most effective when you consume energy during the day—while the panels are producing power.

Great candidates for solar include homes that use:

• Reverse-cycle air conditioning
• Electric cooktops & appliances
• Hot water heat pumps
• Home offices
• Daytime charging (EV)

If most of your usage is at night, adding a solar battery can maximise savings.

---

8. Do You Qualify for Victorian Solar Rebates?

Victorian homeowners may be eligible for:

• Up to $1,400 off solar panel installation
• Matching interest-free loan
• Solar battery rebates (eligibility-based)

These incentives can significantly reduce installation costs.

Melbourne Aircon Specialist works with trusted partners to help guide you through rebate options.

---

9. Local Council & Distributor Requirements

Some areas of Victoria have:

• Export limits
• Solar approval requirements
• Roof installation regulations

We handle all this during your assessment so you don’t have to worry.

Is Your Home Suitable for Solar? — The Final Verdict

Most Melbourne homes are suitable for solar, even if conditions aren’t perfect. Modern panels, micro-inverters, flexible design layouts and government rebates make solar more accessible than ever.

If your home has:
✔ Reasonable sunlight
✔ Adequate roof space
✔ Minimal shading
✔ A solid roof
✔ Suitable electrical setup
Then you’re already on track to benefit from solar.
