The Price Of A 10kW Solar System In Melbourne
How much does it cost to install a 10kW solar system in your Melbourne home or business? What type of system should you be buying? And how much money can you expect to save on your power bills?
Key Takeaways:
10kW Solar System Costs Depend on Quality and Features
A 10kW solar system in Melbourne starts at $12,000 with high-quality panels from 1KOMMA5°. A smart solar system with Enphase Microinverters will command a higher cost. Investing in premium components ensures long-term reliability and maximum energy savings.
Government Rebates and Financing Enables Homeowners Access Solar Solution
In addition to the federal government’s solar rebate, Melbourne homeowners can claim a $1,400 rebate through the Solar Homes program. Interest-free loans and green loan financing options often allow systems to be cash-flow positive from day one.
Battery Storage Maximises Solar Benefits
Adding a 13.5kWh battery (starting from $21,000) allows homeowners to store excess energy for nighttime use or backup during blackouts. If claiming the Victorian battery rebate ($2,950), homeowners must forgo the $1,400 solar rebate.
The Price of a 10kW Solar System in Melbourne Victoria
A 10kW solar system is perfect for households or businesses in Melbourne that use around 35-40kWh of energy during the daytime or consume more over 24 hours, especially if you’re considering battery storage.
This system is large enough to deliver significant savings over the next 25 years, making it a smart investment. To ensure optimal performance, reliability, and longevity, it's essential to choose a high-quality system.
A 10kW solar system that offers great value starts at approximately $12,000. This price includes top-quality panels designed for efficiency. Keep in mind, this is before applying the federal government’s solar rebate, which is directly deducted from the purchase price to make renewable energy more affordable.
Melbourne residents have the added benefit of a $1,400 rebate through the Victorian government’s Solar Homes program, in addition to the federal rebate. However, eligibility criteria apply, so it’s important to check that you qualify for this rebate.
To make going solar even easier, various financing options are available. Solar Victoria offers an interest-free loan of up to $1,400, which matches the solar rebate, helping to reduce upfront costs. Additionally, 1KOMMA5° partners with finance providers that offer Green Loans, making solar even more accessible.
In many cases, solar systems are cash flow positive from day one, meaning the savings on your power bill can exceed the loan repayments. Once the loan is paid off, you'll enjoy significantly lower power bills for years to come.
It’s no surprise that over 30% of Australian households have made the switch to solar. With the combination of government rebates and financing options, it’s more affordable than ever to take advantage of solar energy and start saving.
How Much Can a 10kW Solar System Save You?
A 10kW solar system in Melbourne on an unshaded north-facing roof will output approximately 36kWh a day according to the Clean Energy Council Guideline. It will output more in summer compared to winter, and from our experience installing quality products makes a significant difference.
There are also feed-in tariffs available from your energy retailer for excess solar power that is sent back into the grid.
Over the life of the system, your 10kW system can earn you well over $100,000 in total savings.
What Are the Best Solar Products to Buy?
A solar PV system that is mounted on your roof will be exposed to the Melbourne weather through rain, hail, burning Aussie sunshine, and furious winds—all while performing perfectly for 100,000 hours over its 25-year lifespan.
Quality products and a trustworthy installer are the keys to making all of this work.
Solar Panels for a 10kW Solar System
A top-quality 10kW system starts from around $12,000, including premium panels and a straightforward installation (no cherry pickers etc.). It’s important to note that when it comes to solar panels, you generally get what you pay for. Most of our customers are choosing to install top-of-the-range panels like modules from 1KOMMA5° Solar to ensure optimal savings over the life of their systems.
When you’re looking at a larger system, roof space is also a consideration. Choosing high-efficiency panels means we could install 23 x 450W solar panels.
Solar Inverter for a 10kW Solar System
Your choice of inverter makes a huge difference to your system. The two options to consider are string inverters (the old technology) and micro inverters (the newer tech). A string inverter system is like fairy lights strung together in sequence. The biggest limitation with this type of system is that your panels all perform at the level of the lowest-performing panel. Shade, bird droppings, dust, chimneys and power lines can all affect the output of your panels:
Good solar panels also have a positive power tolerance, meaning some perform above the number of watts they’re labelled. Trina 450W panels, for example, can be rated from 450W to 455W. With a string inverter, you’re not able to take advantage of any extra performance from individual panels, but with an Enphase system, you can.
Because of this, we choose to include Enphase Microinverter with all of our Melbourne Solar Systems. Using Enphase microinverters may cost a little more upfront, but it pays off. Your system is now optimised to get the best performance out of each panel.
It also gives you greater flexibility in how your panels are set up. By using microinverters, we can design a panel array that spans different orientations and angles across different areas of your roof to catch the sun at different times of the day. This helps you use a higher percentage of solar power as it’s generated by avoiding a big peak of solar power in the middle of the day.
Adding Battery Storage to Your 10kW Solar System
With a 10kW system, you might be considering battery storage to store the energy you can’t use during daylight hours. With a solar system combined with battery storage, it’s possible to run your household or business almost entirely on solar power.
For a 10kW solar system, you’ll need to consider one of the larger household batteries such as the Tesla Powerwall. Tesla Powerwall gives you 13.5kWh of storage capacity, and an online monitoring system you can use on your smartphone.
A Tesla Powerwall currently costs around $20,500 in Melbourne before rebates, with a slightly higher price for homes with 3-phase power.
This sleek, cutting-edge battery is an excellent companion to a 10kW solar system. It includes backup functionality, allowing you to keep essential appliances running during a blackout—like your modem, lights, fridge, or freezer.
Keep in mind that Solar Victoria only allows one rebate per household. If you're planning to add battery storage in the future, it’s often better to skip the $1,400 solar rebate so you can take advantage of the $2,950 battery rebate when the time comes.
