Sustainable solar power for regional agribusiness
Located in regional New South Wales, Maromac Nursery partnered with Rainbow Power Company to secure a reliable and sustainable energy supply for its expanding agricultural operations. The nursery required a dependable power source to support irrigation, refrigeration, and production systems in an area with limited grid access and frequent supply interruptions.
Rainbow Power Company designed and installed a complete off-grid solar-battery system that now provides continuous electricity for the business throughout the year. The project demonstrates how modern renewable energy systems can strengthen agricultural productivity while lowering running costs and reducing environmental impact.
Project Overview
Maromac Nursery produces a wide variety of plants for wholesale and retail markets. The business depends heavily on power for water pumping, climate control, and cold storage. High fuel costs and maintenance issues associated with diesel generators created financial and operational pressure, particularly during long dry seasons when irrigation demand peaks.
To address these challenges, Rainbow Power Company supplied a 10 kW on-grid solar system. The installation provides the nursery with complete energy independence, ensuring round-the-clock electricity for production and site management without reliance on diesel fuel.
System Design and Integration
The system was designed to deliver reliable, low-maintenance energy for agricultural use. The solar array powers daytime irrigation and production activities while charging the battery bank for overnight and early-morning operation. The SMA inverter technology provides efficient power conversion and supports load prioritisation, ensuring that critical systems such as pumps and refrigeration are always supplied first.
All equipment was selected for durability and performance in hot, dusty rural environments. Rainbow Power Company’s engineering team configured the system for remote monitoring and simple operation, allowing staff to manage energy use through an intuitive control interface. The modular design also enables future expansion as production grows or additional facilities are added to the site.
What They Said
“Reliable power is essential for regional producers. Projects like Maromac Nursery show how renewable energy can improve productivity while cutting operating costs and emissions. This installation provides the stability needed for modern agribusiness.”
— Paul O’Reilly, Business Development Manager, Rainbow Power Company
Outcomes
Since installation, Maromac Nursery has enjoyed consistent power availability with minimal maintenance requirements. The removal of diesel generation has lowered operating costs and reduced noise and emissions across the property.
Reliable electricity has enabled more efficient irrigation scheduling, supported controlled-temperature storage, and reduced product losses during peak production periods. The nursery now operates with greater confidence and efficiency, ensuring a dependable supply to customers while strengthening its environmental credentials.
Project Suitability
This project highlights Rainbow Power Company’s capability in designing off-grid systems for agricultural and horticultural businesses. The combination of advanced battery storage, intelligent load control, and scalable design makes the solution ideal for farms, nurseries, and agribusinesses seeking independence from the grid.
The Maromac Nursery installation demonstrates how renewable energy can power rural productivity while promoting sustainable growth across Australia’s agricultural sector.
