For industrial businesses, electricity costs are a significant part of operating expenses. Hillcrest Mushroom, a company with over 20 years of experience in the industrial production of mushrooms, has found a smart solution to reduce these costs through solar energy. By installing a commercial solar system, Hillcrest Mushroom now saves approximately $22,000 annually while also contributing to a cleaner, more sustainable future.
Hillcrest Mushroom has been specialising in mushroom production for over two decades. They supply mushrooms to all major grocery chains, as well as boutique stores, making them a key player in the Australian fresh produce industry.
Their factory operates 24 hours a day, seven days a week, as mushrooms require constant monitoring and controlled environments for incubation and growth. This continuous operation results in high electricity consumption, on average, 2.3MWh per day. For a business of this size, energy costs can be significant, especially when electricity prices are volatile.
Faced with rising energy bills and to gain more control over their operating costs, Hillcrest Mushroom decided to explore solar power as a solution.
Why Hillcrest Mushroom Chose Solar
There were several reasons behind Hillcrest Mushroom’s decision to invest in solar energy –
Control over Energy Costs – Hillcrest Mushroom now is more certain about how much they spend on electricity each month. Before installing solar, the company relied entirely on the electricity grid, where prices can change frequently and unpredictably. This made it hard to plan expenses.
By installing a solar system, the company now produces some of its own electricity. This reduces their dependence on the grid and gives them more stable and predictable energy costs. Essentially, they can plan their budget better, avoid surprises from rising electricity prices, and save money in the long run.
Cost Savings – It was previously spending a large amount on electricity, as its operations require significant energy and grid prices have been steadily rising. This made power one of the company’s major expenses.
By switching to solar, they can now generate a significant portion of their own electricity instead of buying it all from the grid. This reduces their power bills and allows them to save more than $22,000 each year, improving their profitability. In other words, the money they used to spend on electricity can now be reinvested into growing the business.
Sustainability Goals – Installing a solar system helped Hillcrest Mushroom take a major step toward environmental responsibility. By generating clean, renewable energy, the company significantly reduced its reliance on fossil fuels and lowered its carbon emissions. This move aligns with their long-term goal of running an energy-efficient, eco-friendly operation, allowing them to maintain high production levels while contributing to a greener, more sustainable future.
Reliable Performance – Hillcrest Mushroom operates around the clock, so reliability was a top priority when choosing an energy solution. Their solar system was designed to deliver steady, uninterrupted power to support daily operations. By using high-performance Trina Solar panels and SolarEdge DC Optimisers, the system maximises energy generation, even when parts of the roof are shaded or conditions vary throughout the day. This combination ensures consistent energy output, keeping their production running smoothly without disruptions and providing long-term dependability for their business.
How the Solar System Was Installed
Hillcrest Mushroom’s solar installation was carefully planned to suit their factory requirements. The project included both rooftop panels and advanced optimisation technology to maximise output. Here is the installation process –
Site Assessment and Planning
Before installation, the site was assessed for roof space, orientation, shading, and energy requirements. The large factory roof was ideal for a rooftop solar installation, providing ample space for solar panels to capture maximum sunlight throughout the day.
Panel Layout and Orientation
The team designed a layout that positioned the panels to face the optimal direction, ensuring maximum solar exposure. SolarEdge DC optimisers were included to reduce the impact of any shading on the roof and ensure that each panel could operate at its peak efficiency independently.
Electrical Integration
After the solar panels were securely mounted on the roof, the next step was to connect them to SolarEdge inverters. These inverters play a crucial role, they take the DC (direct current) electricity generated by the panels and convert it into AC (alternating current) electricity, which is the type of power used by the factory’s machines and equipment. This integration ensures that the solar energy produced can seamlessly power day-to-day operations.
Testing and Commissioning
Once the installation was complete, our team carefully checked each component, verifying that the panels were generating power as expected, the inverters were converting energy properly, and the SolarEdge optimisers were performing optimally to maximise output.
After all the performance and safety checks were successfully completed, the system was officially commissioned, it was approved for regular operation. Finally, it was connected to Hillcrest Mushroom’s grid connection, allowing the solar power to flow seamlessly into the factory’s energy network and start delivering real savings.
Components Used in the Installation
The selection of high-quality components was crucial for the system’s performance and longevity. Here are the key components used –
Model – 360W
Quantity – 276 panels
Trina Solar panels were chosen for their cost-competitive price and reliability. These panels are known for high efficiency and long-term durability, making them suitable for industrial applications.
2.SolarEdge Inverters and DC Optimisers
Inverter Model – 27.6kW
Key Feature – Commercial Power Optimisers
The SolarEdge system ensures that each panel performs optimally, even if parts of the roof are shaded. The DC optimisers allow each panel to work independently, maximising the total energy output.

Why Businesses Should Consider Solar
Hillcrest Mushroom’s story highlights why solar is an excellent choice for industrial and commercial businesses –
Businesses that operate continuously, like factories, cold storage facilities, and production plants, can save thousands of dollars annually.
With payback periods typically between 4 – 6 years for commercial installations, solar is a financially smart investment.
Businesses contribute to reducing greenhouse gas emissions, aligning with global and corporate sustainability goals.
Solar systems can be designed to expand in the future, allowing companies to gradually increase energy independence.
Solar combined with battery storage provides protection against outages and grid instability.
Reducing Energy Costs and Building a Sustainable Future with Solar
Hillcrest Mushroom demonstrates how industrial businesses can save money, improve energy reliability, and adopt sustainable practices by going solar. With a 99.36kW system consisting of Trina Solar panels and SolarEdge optimisers, they now produce an average of 390kWh per day, reduce electricity costs by 19%, and enjoy annual savings of $22,776.
Solar energy isn’t just for residential homes, industrial and commercial businesses gain financial and environmental benefits from switching to solar. For companies looking to control energy costs, increase sustainability, and future-proof operations, Hillcrest Mushroom’s story is a perfect example of what’s possible.
