A 50 kW solar system is ideal for medium to large businesses with significant daytime electricity usage. This includes manufacturing workshops, supermarkets, schools, hotels, and large office buildings with power bills ranging from $3,000–$6,000 per month. This System designed for businesses that want to cut operating costs while demonstrating a commitment to sustainability.
On average, a 50 kW solar system produces around 200–220 kWh of electricity per day, depending on your location, season, and roof orientation. Northern states like Queensland generally achieve higher daily output compared to southern states.
The number of panels depends on the panel wattage:
Using high-efficiency panels reduces the total number required and minimises roof space usage.
A 50 kW system usually requires between 250–330 square metres of roof space, depending on the efficiency of the solar panels and the layout of the roof. Large, unshaded, north-facing areas deliver the best performance.
In 2025, the cost of a quality 50 kW solar system in Australia typically falls between $45,000 and $65,000 after Small-scale Technology Certificates (STCs) rebates. The final price depends on factors such as equipment brands, inverter type, and any electrical upgrades required.
The businesses that benefit the most are those with consistent daytime energy demand, such as:
These businesses can offset a large portion of their energy consumption directly with solar, leading to faster returns.
Most businesses see a payback period of around 3 to 5 years, depending on energy consumption and local tariffs. With rising electricity prices, the savings often accelerate, making a 50 kW system a highly attractive long-term investment that continues to generate benefits for 20+ years.
