Is This the Right Time to Install Solar in Perth?

For many Perth homeowners, the question is no longer simply “Should I get solar?” It is becoming “When is the right time to get solar?”

Electricity costs remain an important household expense, while Perth's abundant sunshine creates a strong opportunity to generate electricity at home. At the same time, solar and battery technology has continued to develop, and government incentives are helping eligible households reduce the upfront cost of battery storage.

As of 1 July 2026, the WA Government's standard residential A1/A2 electricity tariff is 33.2621 cents per kWh, compared with 32.3719 cents per kWh from 1 July 2025. The daily supply charge also increased from $1.1605 to $1.1924.

That does not mean every Perth household will automatically save money by installing solar. Your result depends on your electricity use, system size, roof, installation cost, tariff and how much solar energy you use yourself.

But for a homeowner already facing substantial electricity consumption, the combination of Perth's solar resource, current incentives and improving technology makes now a particularly important time to investigate your options.

Why Solar Panels Perth Are Getting More Attention

The real issue: upfront cost versus long-term value

The biggest hesitation many homeowners have is understandable: solar requires an upfront investment.

You pay for panels, an inverter, installation and potentially a battery before the savings appear on your electricity bills.

The better question is therefore not simply:

“How much does solar cost?”

It is:

“What will this system cost me after incentives, and how much electricity could it help me generate and use over its operating life?”

That distinction matters.

A cheaper system that produces less energy or has poor installation quality may not necessarily offer better value than a properly designed system with reliable equipment and professional installation.

For Perth homeowners considering solar panels, the goal should be long-term value rather than the lowest quote.

1. Electricity Prices Make Energy Efficiency More Valuable

One of the strongest reasons to investigate solar is the ongoing cost of buying electricity from the grid.

The WA Government's current residential A1/A2 electricity charge is 33.2621 cents per kWh, excluding the daily supply charge.

Solar does not eliminate your electricity bill completely, because most homes will still use some grid electricity. However, generating electricity at home can reduce the amount of electricity you need to purchase.

Your potential benefit is particularly relevant if your household has substantial daytime electricity consumption.

For example, a Perth household might use solar-generated electricity to help power:

The more electricity you can use directly from your solar system, the more useful your solar generation can be.

A key point homeowners often miss

Solar savings are not simply about how much electricity your panels generate. They're also about when your household uses electricity.

This is why system design and energy-use habits matter.

2. Battery Incentives Are Changing the Equation

For homeowners considering solar batteries in Perth, 2026 is particularly significant.

The Australian Government's Cheaper Home Batteries Program provides a discount of around 30% on eligible small-scale battery installations from 5 kWh to 100 kWh. The program applies to batteries connected to new or existing solar PV systems.

There is also a WA Residential Battery Scheme.

Eligible Synergy customers can receive a WA rebate of up to $1,300, while eligible Horizon Power customers can receive up to $3,800, subject to the scheme's requirements. The WA scheme works alongside the federal battery support.

Importantly, these programs have eligibility requirements. Batteries may need to be approved products, installations must meet the relevant requirements, and WA scheme participants must meet conditions including Virtual Power Plant participation.

There is another reason not to assume today's incentive will remain unchanged forever: the federal battery program's support is scheduled to decline over time as battery prices are expected to fall. The government says the STC factor used to determine support will reduce in stages through 2030.

In practical terms, homeowners considering a battery should check their current eligibility rather than assuming the same incentive will be available indefinitely.

3. Solar Technology Has Become More Flexible

Modern solar is not simply about putting panels on a roof and sending excess electricity to the grid.

Today's systems can combine:

Solar panels + inverter + battery storage + energy monitoring

This gives homeowners more control over how electricity is generated, stored and consumed.

Modern systems can also provide better monitoring, allowing homeowners to see how much energy their panels are producing and how much electricity their household is consuming.

WA has also introduced updated connection requirements for new or upgraded rooftop solar and battery systems on the South West Interconnected System from 1 May 2026. The changes are designed to support greater rooftop solar and battery uptake while enabling more flexibility around future electricity export opportunities.

For a homeowner, the takeaway is simple:

Don't choose a solar system only for what your home needs today. Consider what your energy needs could look like in five or ten years.

That might include a battery, electric vehicle, pool equipment or increased air-conditioning use.

4. What Does a Real Perth Solar Installation Look Like?

Real installations show why there is no universal solar package.

Solar 365's recent Baldivis case study describes an 11.875 kW residential solar system designed for a family of five. The system was estimated to generate approximately 19,300 kWh annually, with an estimated annual saving of $3,715. These figures are specific to that property and should not be treated as a guaranteed result for another home.

The system was designed after considering the property's roof, available space and the direction receiving the most sunlight.

Another example comes from Churchlands, where a single mother wanted battery storage but had a strict budget. Rather than immediately choosing the first option, the customer compared quotes and considered different battery sizes and prices over several months. Eventually, a 30 kWh FoxESS battery with a 5 kW inverter was installed alongside her existing 6.6 kW solar panels.

The important lesson isn't that every homeowner needs an 11.8 kW solar system or a 30 kWh battery.

It is this:

The right system depends on the property, household and budget.

5. What Could Stop You From Going Solar Right Now?

Going solar can be a smart decision, but there are genuine challenges.

Upfront investment

Even with incentives, a quality solar or solar-and-battery system can require significant initial spending.

Solution: Compare the total system cost, available incentives, expected energy use and long-term value rather than simply choosing the cheapest quote.

Your roof may not be ideal

Shading, limited roof space, roof orientation or an ageing roof can affect system design.

Solution: Request a proper site assessment before committing.

A battery may not be right for everyone

A battery can increase self-consumption, but its financial value depends on your household's electricity usage, solar generation, battery cost and available incentives.

Solution: Ask for a battery-specific assessment rather than automatically adding one to your solar package.

Too many choices

There are numerous panel, inverter and battery brands available.

Solution: Focus on efficiency, warranties, compatibility, installer experience, monitoring and after-sales support—not just brand names.

6. How to Decide If Now Is the Right Time for You

Before requesting a quote for solar panels in Perth, work through these five questions:

1. How much electricity does my household use?

Review your recent electricity bills and identify your average consumption.

2. When do I use the most electricity?

If you use significant energy during daylight hours, solar may provide greater direct-use opportunities.

3. Is my roof suitable?

Consider orientation, shading, usable space and roof condition.

4. Do I need a battery?

Don't assume you do. Compare the expected benefit against the additional investment and available incentives.

5. What happens after installation?

Ask about monitoring, warranties, maintenance, troubleshooting and after-sales support.

Solar 365 currently states that it has installed 4,000+ solar systems across Perth and has a team of more than 30 professionals, including designers, installers and licensed electricians.

These company claims should still be considered alongside independent checks, written quotes and your own comparison of installers.

Why Now Could Be the Right Time to Investigate Solar

There is no universal date when solar suddenly becomes worthwhile for every household.

However, several factors make 2026 a particularly relevant time for Perth homeowners to investigate solar:

None of these points guarantees a specific payback period or annual saving.

Instead, they create a strong reason to run the numbers for your own property now.

Conclusion: Don't Guess—Get the Numbers

For Perth homeowners, the decision to install solar should not be based on fear of rising bills or pressure from a salesperson.

It should be based on your electricity usage, your property, your budget and the incentives available to you today.

The upfront investment is real. So are the potential long-term benefits.

The most sensible approach is to:


  1. Review your electricity bills.

  2. Assess your roof and household energy use.

  3. Check current federal and WA incentives.

  4. Compare multiple solar quotes.

  5. Ask whether a battery genuinely makes financial sense.

  6. Confirm equipment warranties and installer credentials.

  7. Calculate the expected long-term value before signing a contract.

If you're considering solar panels Perth, now could be the right time to investigate—not because solar is guaranteed to save everyone the same amount, but because the combination of local electricity costs, available incentives and evolving technology makes the decision worth calculating carefully.

Ready to find out whether solar makes sense for your Perth home? Explore your options, request a property-specific assessment and compare the numbers before making your decision.

With the right system, solar can be more than a way to generate electricity—it can become a practical part of a long-term household energy strategy.
