solar panels Melbourne: Compare system installers and prices
The first question that arises in everyone’s mind in victoria is Are solar panels still worth the investment in Melbourne? It seems so Thousands of Victorian households have installed solar panels or PV systems in the last decade alone, in Melbourne area now with 10-20% of homes are meeting at least part of their energy needs with the sun. This article discusses the case for solar panel in Melbourne, Victoria.
If you are Interested in buying solar power for your Melbourne-based business then you should read our article on Commercial Solar Power in Melbourne.
There are many reasons you should go solar but we have discussed 4 Reasons to Go Solar in Melbourne, Victoria.
1. Harness the sun to power your home
It’s a fact that Australia has became a home to some of the best solar energy resources in the world. Even though Melbourne is at more south than Sydney or Brisbane, there’s still enough sun power or sunshine to make panels a profitable investment for households in the region.
A typical Melbourne home’s roof according to experts receives about 4.7 kilowatt-hours (kWh) or more of raw sunshine per square meter on a daily basis, while other experts analysis averages work out to about 4.18kWh. Essential,Basically this sunshine or sunlight is the ‘fuel’ for the solar systems installed in the region.Although not physically possible, If a solar PV system could be 100% efficient it makes possible for a 1 kilowatt (kW) solar system in Melbourne to produce between 4.17kWh – 4.79kWh of energy per day, and a 2kW system would produce double power compared to the 1 kw system.
However In real life, there are efficiency differences or should we say losses that must be taken into consideration between the time the sun hits your panels and when it exits on the solar system’s inverter. The below mentioned table shows a rough daily energy output figures for a variety of popular solar system sizes if installed on a north-side facing roof in Melbourne area, If we assume an efficiency loss of around 25% or a bit less.
Approximately daily solar Photovoltaics system yields in Melbourne some of the Popular system sizes, at about 85% efficiency.
Avg daily system output Solar system size (kilowatt-hours)
1.49kW 4.71kWh – 5.42kWh
2.1kW 6.4kWh – 7.3kWh
3.0kW 9.5kWh – 10.4kWh
4.1kW 12.4kWh – 14.5Wh
5.0kW 15.8kWh -18.7kWh
7.2kW 21.8kWh – 25.4kWh
10.1kW 31.2kWh – 36.4kWh
How solar energy saves you money
If you are a melbourne resident then You have to purchase all of your electricity from an energy retailer when you are grid is not connected with any solar system, . Normally, you will pay around 21 cents for every kilowatt-hour you use.
This means that having solar panels by reducing your need to purchase energy from the grid allow you to save money– every unit of solar energy you ‘self-consume’ in your home is a unit that you do not need to pay for. A possibility to earn credits (a minimum of 12c/kWh) for selling your energy into the grid, but you’ll save far more money by focusing on maximising your solar self-consumption.
2. Solar incentives by the federal government
There is no more state-based feed-in tariff incentive in Victoria, the federal government’s Renewable Energy Target consists of a mechanism that decreases the up-front cost of solar installations under 100kW in capacity.
There are a number of factors upon which the actual value of the incentive depends such as system size and location, but usually works out to be around 30% of the total installation cost. This is basically one of the important reasons why Australia is the home to some of the lowest solar PV or solar power system prices in the world.
As an example,it results in a reduction of $2,200 to $2,950 off the sticker price. when this incentive is applied to a 5 kilo Watt solar system in Melbourne.

3. Solar systems are affordable
Thanks in the Victorian State scheme and great part to the RET as Melbourne has became the home to some of the lowest Solar Panel system installation prices in the world – The main reason or probably one of the reasons that there are such large amounts of rooftop solar installed across the region.
The chart below shows the average solar prices in Australia from early August 2012 to 2019.The prices of melbourne and their Average are represented by the light blue line. All these prices are in dollars per watt ($/W) format to make it easy to compare pricing across system sizes.
Solar panels a great return on investment in Melbourne:
Melbourne home owners that uses solar power can save hundreds of dollar per year, which when is combined with low system prices discussed earlier helps get their money returned into payback periods as short as 3-6 years. It depends on how much of solar energy is used by their homes directly. Keep this fact in mind, however it is also a reality that lower prices don’t always necessarily mean lower quality, sometimes low price can also give you some of the best panels but it depends on your solar provider and also they should be approached with a healthy degree of caution.
A solar PV system in melbourne as it is expected that it should continue to produce power for up to 24 or 25 years (with replacements of inverter every 7-12 years). As we know Any system downtime (due to any reason like component failure) will result in extended payback periods along with the costs that may be incurred for replacements or repairs not covered in warranty.
The table mentioned below gives an overview of the case for investing in various size systems in the Melbourne area. The table uses average system prices keep this fact in mind that lower system prices can or should deliver more impressive returns when used in the right way. Furthermore, we generally use conservative figures for the example menntioned below that include’s an efficiency rate of 75% and ‘high’ and ‘low’ self consumption of solar scenarios for different system sizes.
What about battery storage in Melbourne homes are they worth it?
when we talk about solar panels in melbourne we basically refer to the savings that the residents in the area can do by installing solar but One way to increase solar self-consumption which is so important to have a battery storage system installed.
Adding Battery Storage To Your Solar System
You will need a battery storage If you mostly use electricity outside daylight hours then adding a battery can be a great way to use more of your excess solar power. Battery technology became more popular recently, it’s now possible to save solar which you don’t use during day time to keep things running overnight rather than relying on the grid once the sun’s set. Although they are still quite pricey but they are rapidly becoming more affordable.
