Why More Australian Homeowners Are Installing Solar Panels

Australia enjoys some of the highest levels of solar radiation in the world, making rooftop solar an excellent investment for residential properties.

Installing solar panels allows homeowners to generate clean electricity directly from the sun, reducing dependence on the grid while lowering monthly electricity bills.

Key benefits include:

Lower electricity costs
Protection against rising energy prices
Increased property value
Reduced carbon footprint
Greater energy independence
Opportunity to add battery storage
Long-term return on investment

For many households, a professionally designed solar system pays for itself over time while continuing to generate free electricity for decades.

How Do Solar Panels Work?

Solar panels convert sunlight into electricity using photovoltaic (PV) cells.

The process is simple:

Sunlight hits the solar panels.
The panels generate direct current (DC) electricity.
A solar inverter converts DC electricity into usable alternating current (AC).
Your home uses the electricity to power lights, appliances and air conditioning.
Any excess electricity can be exported to the grid or stored in a solar battery for later use.

This allows homeowners to maximise the use of renewable energy while reducing reliance on electricity retailers.

Solar Batteries, Government Incentives, Savings and Choosing the Right Home Solar System

Installing solar panels is an excellent way to reduce household electricity costs, but adding a solar battery can help Australian homeowners use even more of the energy their system generates.

Without a battery, your home uses solar power as it is produced during the day. Any excess electricity is usually exported to the grid in exchange for a feed-in tariff. With a battery, surplus solar energy can be stored and used later in the evening, overnight or during periods when electricity prices are higher.

For many Australian households, combining solar panels with battery storage provides greater control over energy use and reduces reliance on electricity retailers.

At ADS Solar, we design residential solar and battery systems around each household’s electricity usage, roof space, budget and future plans. This helps homeowners avoid installing a system that is too small, unnecessarily oversized or poorly matched to their daily energy habits.

Should You Add a Solar Battery to Your Home?

A solar battery is not essential for every household, but it can significantly improve the way you use your solar energy.

A battery may be particularly beneficial when:

Your household uses a large amount of electricity in the evening
Most family members are away during the day
You want to reduce reliance on the grid
You are concerned about rising electricity prices
You want backup power for selected appliances
You plan to charge an electric vehicle
Your solar system regularly exports large amounts of electricity
Your feed-in tariff is much lower than the price you pay for grid electricity

For example, a household may generate excess solar electricity during the middle of the day when no one is home. Instead of exporting that energy at a relatively low rate, a battery can store it for use after sunset when cooking, lighting, heating, cooling and entertainment systems are operating.

How Does a Home Solar Battery Work?

A home battery works alongside your solar panels and inverter.

The typical energy flow is:

Your solar panels generate electricity during daylight hours.
Your home uses the solar power it needs first.
Excess solar electricity charges the battery.
Once the battery is full, remaining energy may be exported to the grid.
In the evening, the battery supplies stored electricity to your home.
Grid electricity is used only when solar and stored battery energy are unavailable.

This process can increase solar self-consumption and reduce the amount of expensive electricity purchased from the grid.

Some battery systems also offer backup functionality. When correctly configured, they may continue powering selected circuits during a blackout. Backup capability depends on the battery model, inverter, switchboard design and installation configuration.

Solar Battery Sizes for Australian Homes

Choosing the correct battery capacity is important. A battery that is too small may not store enough energy for your evening needs, while a battery that is too large may remain underused.

Below is a general guide.

Battery Capacity	Best Suited For	Typical Application
5kWh	Small households	Essential evening usage
10kWh	Average family homes	Regular evening consumption
13kWh	Growing families	Higher overnight demand
15kWh	Larger households	Air conditioning and appliance use
20kWh	High-energy homes	EV charging and substantial evening demand
25kWh–30kWh+	Large homes and commercial properties	High consumption and expanded backup needs

The ideal size should be based on your actual electricity consumption, not simply the largest battery available.

ADS Solar reviews your electricity bills, daytime usage, evening demand and solar generation before recommending a suitable battery.

Daytime energy usage
Electricity tariff
Feed-in tariff
Roof orientation
Shading
Local climate
Whether battery storage is installed

Indicative annual savings may include:

Solar System Size	Estimated Annual Savings*
6.6kW	$1,200–$1,800
10kW	$1,800–$2,800
13.2kW	$2,500–$3,500
15kW	$3,000+
20kW+	Based on consumption and system design

*Savings are estimates only and will vary between households.

Homes that use more electricity during the day often achieve stronger solar-only savings because they consume the electricity directly as it is generated.

Homes with high evening usage may gain additional value from battery storage, particularly where grid electricity rates are significantly higher than available feed-in tariffs.

Solar Panels and Battery Savings Together

A solar-and-battery system can help a household use a larger percentage of the energy it generates.

Indicative combined savings may include:

Solar and Battery Package	Estimated Annual Savings*
6.6kW solar with 9.6kWh battery	$1,200–$1,800
10kW solar with 12.8–16kWh battery	$1,800–$2,800
13kW+ solar with 16–19.2kWh battery	$2,500–$3,500+

*Actual results depend on energy usage, electricity prices, solar production, battery settings and system design.

A battery does not automatically guarantee better financial returns. Its value depends on how much excess solar energy is available and how much electricity your household uses outside solar generation hours.

This is why professional system design is important.

Government Solar Incentives in Australia

Eligible Australian households may reduce the upfront cost of a solar installation through government-supported incentives.

The most widely used solar incentive is generally provided through the creation of Small-scale Technology Certificates, often referred to as STCs. The value of these certificates is commonly applied as an upfront discount by the solar retailer.

The final benefit depends on:

Solar system size
Installation location
Certificate value at the time
Approved solar panels and inverter
Installation by appropriately accredited professionals
Scheme eligibility requirements

Battery rebates, loans or incentive programs may also be available in certain states or territories. These programs can change, and eligibility requirements may differ depending on property type, household circumstances, battery specifications and installation date.

ADS Solar can explain which incentives may apply to your proposed installation and include eligible benefits in your quotation.

Is It Better to Install Solar Panels and a Battery Together?

Installing solar panels and battery storage at the same time can simplify system design and ensure all components are compatible from the beginning.

Benefits may include:

A properly matched inverter and battery
Simpler installation
Better cable planning
Easier monitoring integration
Reduced need for future electrical changes
A system designed around both daytime and evening usage

However, installing solar panels first and adding a battery later can also be a practical option.

Homeowners who are not ready to invest in storage immediately should consider choosing a battery-ready solar design. This may involve installing a compatible hybrid inverter or planning the switchboard and system layout to support a future battery upgrade.

How to Choose the Right Solar Panels for Your Home

Not all solar panels provide the same efficiency, warranty or long-term performance.

When comparing solar panels, consider the following factors.

Panel Efficiency

Higher-efficiency panels generate more electricity from a smaller roof area. They can be particularly useful for homes with limited roof space.

Product Warranty

A strong product warranty protects against manufacturing defects. Premium panels often offer longer warranty periods than budget alternatives.

Performance Warranty

A performance warranty explains how much output the manufacturer expects the panel to retain over time.

Solar panels naturally experience gradual degradation, but quality products are designed to maintain reliable generation for decades.

Temperature Performance

Solar panels can lose efficiency as temperatures rise. Products designed for hot Australian conditions may offer stronger performance during warm weather.

Manufacturer Reliability

Choosing an established manufacturer can provide greater confidence in product support, warranties and long-term availability.

Roof-Space Requirements

The number of panels required depends on panel wattage and system capacity.

For example, a system using higher-wattage panels may require fewer panels than one using lower-wattage modules. A site assessment helps determine how much capacity can be safely and effectively installed.

Choosing the Right Solar Inverter

The inverter is one of the most important parts of a solar system.

It converts the electricity produced by the panels into usable power for your home.

When comparing inverters, consider:

Conversion efficiency
Product warranty
Monitoring features
Manufacturer reputation
Battery compatibility
System capacity
Single-phase or three-phase requirements
Local technical support

A cheaper inverter may lower the initial quote, but a reliable, properly sized model can provide better long-term performance and reduce the risk of future replacement costs.

How Roof Direction Affects Solar Performance

North-facing panels often provide strong overall production in many Australian locations, but east- and west-facing installations can also perform very well.

North-Facing Panels

These generally provide balanced production through the middle of the day.

East-Facing Panels

These generate more electricity in the morning and may suit households with higher early-day usage.

West-Facing Panels

These produce more electricity later in the afternoon and may benefit households with higher evening preparation, cooling or after-school energy demand.

Split-Orientation Systems

Panels can be installed across multiple roof directions to spread energy generation across the day.

The best layout should be based on household consumption patterns rather than roof direction alone.

What About Shading?

Shading from trees, neighbouring buildings, roof structures, antennas and chimneys can reduce solar generation.

A professional solar assessment should review:

Morning shade
Midday shade
Afternoon shade
Seasonal changes
Tree growth
Roof obstructions
Potential panel placement

Where shading cannot be avoided, suitable system design, panel placement, optimisers or microinverters may help improve performance, depending on the property.

Why Professional Solar Design Matters

A solar system should not be selected using system size and price alone.

A properly designed residential system considers:

Historical electricity consumption
Daytime and evening usage
Roof size and direction
Shading
Switchboard condition
Single-phase or three-phase supply
Battery plans
EV charging
Export limitations
Household growth
Budget and return expectations

A customised design can improve system output, reduce unnecessary spending and support future upgrades.

How Long Does a Home Solar Installation Take?

The installation timeframe depends on several factors, including:

System size
Roof accessibility
Roof material
Electrical upgrades
Battery installation
Backup configuration
Weather conditions
Grid approval requirements

A straightforward solar panel installation may be completed within a day. Larger systems or installations involving battery storage, switchboard work or complex roof layouts may take longer.

Before installation, ADS Solar explains the expected process and any property-specific requirements.

How Much Roof Space Do Solar Panels Need?

The required roof space depends on:

System size
Panel wattage
Panel dimensions
Roof orientation
Shading
Roof obstructions
Required access clearances

As a general rule, higher-capacity systems need more roof space unless higher-wattage panels are used.

For example, a 6.6kW system may require fewer panels when using high-output modules than when using lower-wattage panels.

A professional site assessment is the best way to determine how much solar capacity can be installed safely and effectively.

Do Solar Panels Work in Winter?

Yes. Solar panels continue generating electricity during winter.

Although winter days are shorter and solar output may be lower, cool temperatures can support efficient panel operation. Actual generation depends on:

Location
Weather
Roof direction
Shading
Panel quality
System design

Australian solar systems are designed to produce electricity throughout the year, not only during summer.

Do Solar Panels Work on Cloudy Days?

Yes. Solar panels still generate electricity when it is cloudy, although output is reduced compared with clear, sunny conditions.

Modern solar panels can use both direct and indirect sunlight. A well-designed system will continue contributing to household energy needs across changing weather conditions.

What Happens to Excess Solar Energy?

When your solar system produces more electricity than your home is using, the excess energy can be handled in several ways.

Exported to the Grid

Without a battery, surplus electricity is usually exported to the electricity network. Your retailer may provide a feed-in tariff for eligible exported energy.

Stored in a Solar Battery

If a battery is installed, excess solar energy can charge the battery before remaining power is exported.

Used by Smart Appliances

Some households schedule high-energy appliances to operate during solar production hours.
