50kW Solar System
If you’re running a business, community centre, school, or even a large rural property in Australia, chances are you’ve thought about ways to bring those electricity bills down. One of the most effective options for medium-sized power needs is installing a 50kW solar system. It’s a popular choice because it offers a serious reduction in energy costs without requiring the massive investment and space of utility-scale solar farms.
In many cases, this system size strikes the perfect balance – large enough to generate between 180 and 220 kWh of clean energy per day (depending on location), but still manageable in terms of installation requirements and grid approvals. Whether you’re looking to offset your daytime energy usage, improve your business’s sustainability credentials, or protect yourself from rising electricity prices, a 50kW solar system can deliver long-term value.

How Much Power Does a 50kW System Generate?
The amount of electricity a system can generate depends on factors like location, panel angle, shading, and weather conditions. On average in Australia, a 50kW setup can produce around 200 kWh per day, based on roughly 4 kWh per kW of installed capacity. Of course, seasonal variations apply — for example, Sydney may produce less on a winter day and more during summer.
50kW Solar System – Estimated Daily Output by City
| City | Avg Daily Output | Est. Annual Output |
|---|---|---|
| Adelaide | 185 kWh | 67,525 kWh |
| Brisbane | 200 kWh | 73,000 kWh |
| Canberra | 185 kWh | 67,525 kWh |
| Perth | 205 kWh | 74,825 kWh |
| Sydney | 175 kWh | 63,875 kWh |
| Melbourne | 160 kWh | 58,400 kWh |
Who Should Consider a 50kW Solar System in Australia
A 50kW solar system isn’t your average home setup. It’s built for locations that chew through a solid amount of electricity every day. We’re talking businesses, community facilities, and even some large rural properties where energy demand is high.You might notice plenty of medium-sized commercial operations in Australia leaning toward this size – things like supermarkets, schools, medical centres, and small manufacturing workshops.
These places often have generous roof space, and their daily energy use lines up perfectly with what a 50kW system can deliver.Some farms also find this size a great match, especially those running pumps, refrigeration, and machinery. And when you pair it with a battery bank, you can store excess daytime power for evening use, reducing grid reliance even further. 50kW solar system could be just right.
The Upside of Installing a 50kW Solar System
A 50kW solar system offers a range of benefits that make it an attractive option for many Aussie businesses. First off, the savings on electricity bills can be significant – you could be cutting thousands off your annual power costs just by generating your own energy. On top of that, many systems have a fairly fast payback period, often covering their cost in 3 to 5 years depending on how much power you use and local energy prices.
Government incentives, like the STC scheme, can help reduce upfront expenses, and some states even provide additional support. Maintenance is generally low, with panels requiring only occasional cleaning and basic checks to keep things running smoothly. Beyond the financial perks, switching to solar also has sustainability benefits – reducing emissions and helping boost your business’s eco-friendly credentials.
Possible Drawbacks You Should Know
Upfront cost – While cheaper than it used to be, a 50kW system still requires a solid investment.
Roof space – You’ll need around 250–300m² of usable roof area.
Daytime focus – Without batteries, most savings happen while the sun’s out.
Grid connection limits – Some areas have restrictions on system size, so approvals may be needed.
Price and Installation Costs of a 50kW Solar System in Australia
A quality 50kW solar system in Australia generally starts from around A$19,599 for the equipment, though prices can go higher depending on the brand, inverter type, panel efficiency, and any extra features like monitoring systems. Installation typically costs between A$1,000 and A$3,000, depending on the complexity of the job, your roof structure, and location. Commercial installations may also require additional safety equipment, structural checks, or even grid approval before work begins.
If you’re in a regional or rural area, you might need to factor in some extra travel costs for the installation team. Because this is a commercial-sized system, it’s a good idea to compare quotes from multiple Clean Energy Council-accredited installers to make sure you’re getting the best balance of quality and cost.
How Much Roof Space Will You Need for a 50kW Solar System in Australia?
Let’s get practical — a 50kW solar system needs a fair bit of space. You’re generally looking at around 230 to 300 square metres of unshaded roof area if you’re using standard 440W to 550W panels (pretty common in 2025). The total number of panels depends on the wattage — for example, about 91 panels if you choose 550W ones, or closer to 114 panels for 440W. Installers will assess your roof for direction, pitch, and shading before giving a final layout. North-facing roofs still give the best output in Australia, but heavy shading or the wrong angle can cut performance. If you’re short on space, high-efficiency panels can help, though they usually come with a slightly higher price tag.
Lifespan, Warranty, and Maintenance
Most quality panels come with a 25-year performance warranty and a 10–15 year product warranty. Inverters usually have a 5–10 year warranty, but you can extend that with some brands.
Maintenance is simple – a visual inspection a few times a year, occasional cleaning, and ensuring the inverter is running smoothly. For commercial systems, scheduling a professional check every couple of years is a smart move to keep everything at peak performance.
How Much Can You Save with a 50kW Solar System?
Savings depend on how much of your solar energy you use on-site. A business that consumes most of the generated power could save anywhere from A$8,000 to A$15,000 annually at current energy prices. The more you use it during daylight hours, the faster your system pays for itself. Feed-in tariffs for excess energy can add a bit more, but self-consumption is where the big gains are.
What to Know Before Installing a 50kW Solar System
Many Aussie businesses see a 50kW solar system as a quick way to slash energy bills — but there are a few lessons that often come after the fact. For one, not all solar panels and inverters are built the same. Opting for the cheapest, lesser-known brands can mean lower output or early breakdowns. Installation quality is another big one — a poor or rushed job can cause ongoing performance issues or even void your warranty. While 50kW systems can deliver huge savings, the actual benefit depends on your energy usage patterns, electricity tariffs, and site conditions. Finally, many regret not planning for future add-ons like battery storage or EV charging infrastructure.
