Tell us about your property and electricity requirements. Our team can recommend an appropriate system size and provide a tailored solar quotation.
A complete rooftop solar installation includes much more than the solar panels themselves.
Depending on the proposed system, your quotation may include:
Two homes installing the same nominal solar-system capacity can receive different quotations because every property has different roof and electrical requirements.
Larger systems require more panels, mounting equipment and inverter capacity, increasing the upfront cost.
Pricing varies by panel manufacturer, wattage, efficiency, technology, product warranty and performance warranty.
String, hybrid, three-phase and microinverter systems can have different equipment and installation costs.
Tile versus metal roofing, roof pitch, building height and multiple roof faces can affect installation complexity.
Older switchboards or other electrical infrastructure may need upgrading before the solar system is connected.
Trees, chimneys and neighbouring buildings can affect panel positioning and may influence equipment selection.
Choosing the correct solar-system capacity is one of the most important parts of system design. The right size should reflect your current electricity consumption and future energy needs.
A 6.6kW solar system remains a common option for small and medium Sydney households.
Typical estimated generation may be around 24–28kWh per day, although actual generation varies by season and installation.
A 10kW solar system can suit medium and larger homes with greater electricity requirements.
Typical estimated generation may be around 38–45kWh per day, subject to system design and seasonal conditions.
A 13kW or 13.2kW solar system can suit larger and high-energy homes.
Typical estimated generation may be around 50–60kWh per day, depending on panel orientation, weather, shading and equipment.
Not automatically. Installing more solar panels than your property needs does not always deliver the best financial outcome.
Professional system sizing should consider:
Sydney offers favourable conditions for rooftop solar, but production changes throughout the year.
Actual solar generation depends on:
Summer months generally provide longer solar-production periods, while winter days are shorter. Daily production values should therefore be treated as estimates rather than guaranteed output.
North-facing solar panels generally provide strong annual generation in Sydney, but north-facing roof space is not essential.
East-facing panels produce a greater proportion of electricity earlier in the day.
West-facing panels shift more solar generation towards the afternoon.
An east-west solar system can spread production across a broader portion of the day and may better align with household electricity consumption.
Yes. Solar panels continue to produce electricity from available sunlight during cloudy weather.
Generation is normally reduced compared with clear, sunny conditions, but production does not necessarily stop.
For many households, rooftop solar can reduce the amount of electricity purchased from the grid.
Solar electricity produced and used directly within your property can be particularly useful because it replaces electricity that would otherwise need to be purchased from your retailer.
The financial outcome depends on:
Solar self-consumption is the proportion of electricity generated by your panels that is used directly within your property.
Solar electricity can be used to operate:
Scheduling suitable appliances during solar-production hours can increase the amount of solar electricity consumed directly rather than exported to the grid.
Many Sydney homeowners are considering solar panels with battery storage to make greater use of their own solar electricity.
During daylight hours, solar panels generate electricity that can first be used by your home.
Eligible surplus electricity can then be stored in a compatible solar battery and used later, including during the evening and overnight.
Battery storage may help:
Battery pricing varies according to usable capacity, manufacturer, power output, inverter requirements, backup configuration and installation complexity.
| Battery capacity | Indicative installed price* | Typical application |
|---|---|---|
| 5kWh | From approximately $5,999 | Smaller households |
| 10kWh | From approximately $7,999 | Average households |
| 13kWh | From approximately $8,999 | Medium to larger households |
| 15kWh | From approximately $10,999 | Higher evening electricity use |
| 20kWh | From approximately $13,999 | Large households |
| 25kWh–30kWh+ | Custom quotation | High-consumption properties |
*Indicative pricing only. Actual battery pricing depends on manufacturer, usable capacity, inverter compatibility, backup configuration and site-specific installation requirements.
The best battery for your property depends on usable capacity, inverter compatibility, output, backup requirements, warranty and budget.
Battery sizing should take your household electricity profile into account.
Important factors include:
Solar-panel wattage should not be the only factor used to select a module.

The inverter converts the DC electricity produced by the solar panels into AC electricity that can be used throughout the property.
Common inverter configurations include:
A hybrid inverter can be particularly relevant where battery storage is planned now or in the future.
A professional residential solar panel installation in Sydney should begin with an assessment of the property and its electricity requirements.
Our residential solar design process can consider:
Solar is not limited to residential properties. Sydney businesses can also use commercial rooftop solar to offset electricity consumed during operating hours.
Commercial solar can suit:
Commercial system sizing should consider interval electricity consumption, operating hours, available roof area, tariff structure, export limits and future battery-storage requirements.
Choosing the right solar installer can be just as important as selecting the solar panels themselves.

A residential solar installation can cost approximately $3,999–$16,000+ depending on system capacity, solar panels, inverter selection, roof conditions and electrical requirements.
A 6.6kW solar system remains a common option for small and medium households, while 10kW systems may be more suitable for larger homes and higher electricity consumption.
A 6.6kW system may generate approximately 24–28kWh per day under suitable conditions. Actual production varies by season, shading, orientation, weather and system efficiency.
Indicative production may be approximately 38–45kWh per day under suitable conditions, although actual output changes throughout the year.
A 13kW or 13.2kW system may generate approximately 50–60kWh per day under suitable conditions. Actual performance depends on the property and system design.
It can suit many small and medium households. Homes with electric vehicles, pools, extensive air conditioning, electric hot water or battery plans may benefit from a larger system.
A 10kW system can suit higher-consumption households with sufficient roof area and suitable network conditions. The financial result depends on electricity consumption, installation cost and system design.
Battery storage may make sense where a household generates substantial surplus solar during daylight hours but uses considerable electricity after sunset.
In many cases, yes. If future battery storage is important, discuss compatibility before selecting your inverter and solar-system configuration.
Yes. Solar panels continue generating electricity from available sunlight, although output is normally lower during heavy cloud cover.
North-facing panels generally provide strong annual generation, while east- and west-facing installations can also work effectively and may better match morning or afternoon electricity use.
Standard grid-connected solar systems generally shut down during a grid outage. Backup functionality requires compatible battery equipment, inverter configuration and appropriate electrical design.
The cheapest quotation does not automatically provide the best long-term value. Compare equipment, warranties, system design, installation quality, monitoring and after-sales support.
Choosing the right solar panel system Sydney homeowners can rely on begins with understanding how your property actually uses electricity.
