8kW Solar Installation in Clontarf, Sydney

Installing solar on a multi-storey home can involve different design and installation considerations compared with a straightforward single-storey property.

Roof height, access, available panel space, roof configuration, equipment location, cable routes and the existing electrical setup all need to be considered before the final solar layout is determined.

For this three-storey Clontarf property, MPV Solar designed a 7.92kW rooftop solar system using 22 LG panels and SolarEdge panel-level optimisation.

The finished system was designed around the specific characteristics of the home rather than selecting the solar system based only on a target kilowatt size.

For Sydney homeowners with multi-level or more complex properties, MPV Solar provides tailored solar services across Sydney.

The project involved a three-storey residential home with a flat roof in Clontarf, located on Sydney’s Northern Beaches.

The solar design needed to account for:

• The three-storey property configuration
• Flat-roof installation requirements
• Available roof space
• Panel positioning
• Existing household electrical infrastructure
• Controlled load/off-peak supply
• Inverter configuration
• Panel-level optimisation

The completed system includes:

• 22 × LG 360W solar panels
• 7.92kW total rooftop solar capacity
• 22 × SolarEdge DC optimisers
• 6kW SolarEdge StorEdge inverter
• Controlled load/off-peak electrical configuration

Together, these components created a tailored residential solar system for the Clontarf property.

Each of the 22 solar panels in this installation is paired with a SolarEdge DC optimiser.

Panel-level optimisation allows individual panels to be managed and monitored as part of the wider SolarEdge system.

This can be particularly useful where solar performance may be influenced by factors such as:

• Multiple roof areas
• Different panel orientations
• Partial shading
• Trees
• Roof structures
• Neighbouring properties
• Complex roof layouts

Shading still reduces the amount of electricity a panel can generate, but an optimised solar architecture can provide greater visibility over individual panel performance and help the system manage variations between panels.

MPV Solar explains the role of optimisation and intelligent inverter technology in more detail in its guide to smart solar inverters and energy management.

7.92kW LG Solar Panel System

MPV Solar installed 22 × 360W LG solar panels, creating a total rooftop solar capacity of 7.92kW.

The panels were positioned across the available flat-roof area to create a substantial residential solar array while working within the physical requirements of the three-storey property.

22 SolarEdge DC Optimisers

Each LG panel was paired with a SolarEdge DC optimiser, creating a panel-level optimised solar system.

The optimisers form part of the SolarEdge system architecture and provide visibility and management at individual panel level rather than treating the complete rooftop array as a single unit.

6kW SolarEdge StorEdge Inverter

The system incorporates a 6kW SolarEdge StorEdge inverter.

The StorEdge platform was designed to manage both solar generation and compatible battery storage applications, providing the property with a solar inverter architecture that could support broader home energy requirements.

For homeowners considering energy storage, MPV Solar also provides solar battery installation and storage solutions across Sydney.

This Clontarf home also incorporates a controlled load/off-peak electrical supply.

Controlled load circuits are commonly used for appliances such as electric hot water systems that operate on a separate tariff or controlled supply.

Where a home has both rooftop solar and controlled-load electricity, the existing metering and electrical configuration should be reviewed as part of the overall system assessment.

Solar does not automatically offset electricity used on every controlled-load circuit. Whether solar generation can supply a particular load depends on how the property is metered and wired, as well as the network and retailer configuration.

This is another reason MPV Solar assesses the complete electrical setup of the property, rather than looking at the roof in isolation when designing a residential solar system.

The completed Clontarf installation provides the property with:

• 7.92kW of rooftop solar capacity
• 22 × LG 360W solar panels
• 22 × SolarEdge DC optimisers
• 6kW SolarEdge StorEdge inverter
• Panel-level optimisation
• A solar layout designed for a three-storey flat-roof home
• Integration with the property’s broader electrical configuration

The project demonstrates why residential solar design needs to consider more than simply the number of panels being installed.

Property height, roof design, shading, electrical infrastructure, metering and household energy use can all influence the final solar solution.

Homes across Clontarf and Sydney’s Northern Beaches can present very different solar installation requirements.

Properties in areas such as Clontarf, Seaforth, Balgowlah, Manly, Fairlight, Freshwater, Queenscliff and surrounding Northern Beaches suburbs can include multi-storey homes, flat roofs, complex rooflines, established trees and coastal conditions.

These characteristics can influence:

• Available solar roof space
• Panel orientation
• Shading
• Roof access
• Installation complexity
• Inverter placement
• Electrical infrastructure
• Long-term system maintenance

MPV Solar assesses the individual home before recommending a solar system, taking into account the property itself as well as household electricity consumption and future energy requirements.

MPV already has extensive solar installation experience across Sydney, including completed projects throughout the Northern Beaches. MPV’s current project portfolio includes Northern Beaches installations in areas such as Beacon Hill, Bayview, Mona Vale, Newport, Warriewood, Collaroy and Dee Why.

A three-storey property, flat roof or complex roof configuration does not automatically prevent solar installation.However, these properties require a site-specific approach.

MPV Solar can assess:

• Property height and roof access
• Available roof space
• Roof type and condition
• Orientation and shading
• Electricity consumption
• Existing electrical infrastructure
• Controlled-load circuits
• Switchboard and metering
• Battery requirements
• EV charging plans
• Future household electricity demand

before recommending an appropriate solar system.
