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?

The Price of a 10kW Solar System in Melbourne Victoria

A 10kW solar system in Melbourne is going to fit best a household or a business that uses at least around 35-40kWh during the daytime, or over 24 hours if you are planning to include battery storage.

It’s a large system with the capacity to save you a lot of money over 25 years so it’s important to get a quality system, ensuring reliability, performance, and longevity.

The 10kW solar systems in Melbourne that are worth their salt start at around $11,250. This price will get you top-quality panels from 1KOMMA5°. If you want to upgrade to a smart solar system, an Enphase Solar System with panel-level optimisation starts at around $15,490.

This price is after the federal government’s ‘rebate’ that comes directly off the purchase price to help bring down the cost of renewable energy products like solar.

Lucky residents of Melbourne can also apply for a second rebate as part of the Victorian government’s Solar Homes program. This rebate is $1400 for solar, however, there are eligibility requirements, so it’s worth double-checking to make sure you are eligible.

There are also good financing options available to help you get on the solar train before it’s too late to catch both rebates.

Solar Victoria also offers an interest-free loan up to the value of the rebate ($1400), plus 1KOMMA5° partners with finance providers that offer Green Loans to make solar even more affordable. It is common for solar to be cash flow positive from day one, where the savings on your power bill are actually larger than the repayments. After the loan is paid off, you are then able to enjoy significantly lower power bills for decades to come.

No wonder over 30% of Australian households have gone solar! It simply makes sense.

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 Microinverter system is around $15,500, including premium panels from 1KOMMA5° 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 24 x 425W 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. REC 400W panels, for example, can be rated from 400W to 405W. 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 is currently $14,990 in Melbourne, plus $500 if you have 3-phase power.

This sleek, futuristic battery makes a fantastic addition to a 10kW solar system, featuring a backup functionality to help you run certain things in the home when the grid goes down such as the modem, lights, the fridge/freezer etc.

It is important to note that you can only claim 1 rebate from Solar Victoria so if you are considering battery storage it is best to not claim the $1400 solar rebate. That way, when it comes time to install the battery, you can claim the $2950 battery rebate.
