Four-Tenancy Shared Solar Installation

NEO Energy delivered an innovative shared solar and battery solution for a four-tenancy residential development, allowing multiple occupants and the common area to benefit from a single rooftop solar system. Using the Allume SolShare energy distribution platform, the project intelligently allocates solar energy across four apartments while integrating battery storage for greater energy independence. The installation also included electrical upgrades, roof remediation support, and assistance with the NSW Solar for Apartments Grant application.

Our Process

How we work

Shared solar projects require careful engineering, electrical coordination, and regulatory compliance to ensure every resident benefits from the renewable energy system.

Site Assessment

Our team assessed the building's roof structure, electrical infrastructure, and tenant energy requirements to determine the most effective shared solar solution.

Custom System Design

The system was engineered using Aiko solar panels, Sigenergy battery storage, and the Allume SolShare platform to distribute solar energy across four residences and shared common areas.

Professional Installation

We coordinated roof remediation, completed electrical upgrades, and staged the installation to minimise disruption while maintaining safe access for residents.

Long-Term Performance

The completed system intelligently distributes renewable energy between apartments while storing excess generation in a 40kWh battery system for improved self-consumption.

Challenge & Solution

What We Had to Work Through

⚠ The Challenges

  • A single rooftop solar system needed to supply renewable energy fairly across four separate residences and the building’s common area.
  • The existing roof required remediation before the solar installation could safely proceed.
  • The building’s main switchboard no longer met current electrical requirements for the new renewable energy system.
  • The project required careful planning to minimise disruption while supporting available government funding opportunities.

✓ Our Solutions

  • Installed the Allume SolShare platform to intelligently distribute solar generation between each tenancy and shared facilities.
  • Assisted with roof remediation works to prepare the building for long-term solar installation and performance.
  • Upgraded the main switchboard (MSB) to current standards, providing a safe and compliant electrical foundation for the installation.
  • Staged the installation to reduce inconvenience for residents and assisted the client with the NSW Solar for Apartments Grant application.

Final Outcome

Project Results

A shared renewable energy solution delivering smarter energy distribution, lower electricity costs, and long-term sustainability for multi-residential living.

Shared Solar Benefits

The Allume SolShare system enables four residences and common property to share electricity generated from a single rooftop solar array, improving overall energy utilisation.

Battery Energy Storage

The integrated 40kWh battery system stores excess solar energy for later use, increasing self-consumption and reducing reliance on grid electricity.

Future-Ready Infrastructure

Electrical upgrades, roof remediation, and modern energy management technology have prepared the property for reliable, long-term renewable energy performance.

Why This Project Matters

Multi-residential buildings often face challenges when implementing rooftop solar because multiple occupants share a single roof space. This project demonstrates NEO Energy’s expertise in designing innovative shared energy systems that allow apartment residents to benefit from renewable energy while improving building infrastructure, supporting government incentives, and maximising the value of available roof space.
