11kW Solar System Replacement in Epping, Sydney

Having solar already installed does not necessarily mean the existing system should remain unchanged forever.

Solar technology, household electricity consumption and the way homes use energy can change considerably over the life of a system.

For this Epping property, MPV Solar replaced the existing solar setup with a new 11.44kW rooftop solar system, incorporating 26 Canadian Solar panels and a dual SolarEdge inverter configuration.

The project demonstrates one of the options available to Sydney homeowners when an existing solar system is no longer the configuration they want to retain.

If you are unsure whether your current system should be repaired, expanded or replaced, MPV Solar’s guide to upgrading or replacing an old solar system explains the different pathways.

The project involved a single-storey residential home with a tiled roof in Epping.

Because the property already had solar installed, the project was approached as a replacement system rather than a completely new first-time solar installation.

The new system includes:

• 26 × Canadian Solar 440W panels
• 11.44kW total rooftop solar capacity
• 5kW SolarEdge Energy Hub inverter
• 5kW SolarEdge Genesis inverter
• 10kW combined inverter capacity
• Single-phase system configuration

Replacing an existing system provides an opportunity to reassess the solar setup around the home as it exists today rather than simply retaining the design decisions made when the original system was installed.

11.44kW Canadian Solar Panel System

The replacement installation includes 26 × Canadian Solar CS6R-440T 440W panels, providing a total rooftop solar capacity of 11.44kW.

This gives the Epping property a substantial modern residential solar array using the available tiled roof area.

The appropriate system size for another home may be very different, which is why MPV Solar’s residential solar systems are designed around the individual property and household electricity requirements.

5kW SolarEdge Energy Hub Inverter

The system incorporates a 5kW SolarEdge Energy Hub Single Phase inverter.

The Energy Hub forms one part of the dual-inverter arrangement installed with the new 11.44kW solar array.

SolarEdge Energy Hub technology can also form part of broader home energy configurations where compatible battery storage and other energy technologies may be considered.

5kW SolarEdge Genesis Inverter

A second 5kW SolarEdge Genesis Single Phase inverter (SE5000H) was installed as part of the replacement system.

Together, the two 5kW SolarEdge inverters provide 10kW of inverter capacity for the new 11.44kW rooftop array.

The inverter configuration is an important part of the overall system design and needs to be considered alongside solar panel capacity, the property’s electrical supply and current connection requirements.

No. System age alone is not enough reason to replace solar panels that are still performing properly.

Before removing an older system, it is worth assessing:

• Current solar output
• Panel condition
• Inverter performance
• System reliability
• Existing capacity
• Equipment compatibility
• Household energy consumption
• Future energy requirements

In some cases, targeted upgrades can extend the useful life of an existing system.

In others, replacing the complete system may provide a cleaner pathway to a larger and more modern solar configuration.

For homeowners with systems approaching or exceeding a decade in service, MPV Solar’s guide to solar panels after 10 years explains what to assess before deciding whether to retain, upgrade or replace the system.

The completed Epping solar replacement provides the property with:

• 11.44kW of rooftop solar capacity
• 26 × Canadian Solar 440W panels
• 5kW SolarEdge Energy Hub inverter
• 5kW SolarEdge Genesis inverter
• 10kW combined inverter capacity
• Single-phase configuration
• A new system designed for a single-storey tiled-roof home

The project demonstrates how replacing an existing solar installation can provide an opportunity to reassess system capacity, equipment and configuration around the property’s current requirements.

Homes across Epping and surrounding areas of northern Sydney vary considerably in age, roof design, existing solar equipment and household electricity requirements.

Established suburbs such as Epping, North Epping, Eastwood, Marsfield, Carlingford, Cheltenham and Beecroft also contain many homes where solar may have been installed years ago and the original system no longer reflects the way electricity is used today.

An existing solar system may need reassessment where:

• Household electricity consumption has increased
• The original system is relatively small
• The inverter is ageing or limiting expansion
• Equipment is no longer compatible with future requirements
• Additional solar generation is needed
• Battery storage is being considered
• An EV is planned
• System performance has declined

MPV Solar provides complete solar services across Sydney, including new installations, upgrades, expansions and assessment of existing residential solar systems.

A solar system that was appropriately sized when first installed may not necessarily meet the household’s requirements years later.

Before replacing the system, MPV Solar can assess what you already have and determine whether the better approach is to:

• Keep the existing system
• Repair a specific issue
• Add more solar panels
• Increase inverter capacity
• Redesign part of the system
• Add battery storage
• Replace the entire solar installation

That assessment can help avoid replacing equipment unnecessarily while also identifying when continued investment in an older system may no longer provide the best long-term solution.
