Solar Power for Farms on SWER Lines in Rural Queensland

Upgrading Outdated Infrastructure with Modern Energy Solutions

Across rural Queensland, Single Wire Earth Return (SWER) lines have long served as a critical source of electricity for remote properties. But as farms expand and technology evolves, the limitations of SWER systems are becoming increasingly apparent.

The Problem with SWER in 2025

Farmers relying on SWER lines face ongoing issues such as:

• Voltage fluctuations and instability
• Capacity limits that restrict growth
• Frequent power outages and brownouts
• High susceptibility to weather-related faults

As modern farming relies more heavily on consistent and clean energy — from automated pumps to cool storage and irrigation — many properties are outgrowing what SWER can deliver.

A Smarter Way Forward: Solar and Battery Integration

At AusPac Solar, we help rural customers enhance or transition away from SWER by integrating on-site solar generation and battery storage systems. These setups provide a stable, reliable, and independent power source — ideal for the Australian outback.

Reducing the Load on SWER

Solar systems can dramatically reduce the daytime load placed on SWER lines. By generating electricity locally, farms lessen stress on the network, help stabilise voltage, and extend the lifespan of the infrastructure.

Local Energy Means Less Waste

Solar energy systems produce power close to where it’s used, which reduces transmission losses — a major drawback of long SWER lines. This efficiency translates into better performance and reliability, especially for properties located at the end of a line or on the fringe of the grid.

Battery Storage Keeps Operations Running

Battery storage isn’t just a luxury — it’s an essential part of energy stability. These systems store excess solar energy during the day and release it when demand spikes or grid power fails. This helps:

• Smooth out energy delivery (peak shaving and load balancing)
• Protect sensitive equipment from voltage dips
• Provide backup power during outages or SWER faults

Building a Mini-Grid for Your Farm

Together, solar and battery technologies allow farmers to build a mini-grid — a self-sustaining energy system tailored to their operational needs. It offers better control, scalability, and long-term cost certainty, without the limitations of traditional SWER infrastructure.

The Future Is Reliable, Renewable, and Independent

With the right solar and battery solution, farmers no longer have to rely on outdated and unreliable infrastructure. Whether you're looking to supplement your SWER connection or replace it altogether, AusPac Solar can help you create an energy system that works now and well into the future.
