How a lot power do solar panels produce in Melbourne?

Solar rays passing through hand in Melbourne Victoria

Australia is home to among the greatest solar energy sources on the planet. Although Melbourne is a bit additional south than Brisbane or Sydney, there’s nonetheless sufficient sunshine to make panels a worthwhile funding.

According to PVWatts, a typical Melbourne home’s roof receives about 4.8 kilowatt-hours (kWh) of uncooked sunshine per sq. meter per day, whereas the Bureau of Meteorology web site averages work out to about 4.18kWh. Essential, this daylight is the ‘fuel’ for the system. If a solar PV system may very well be 100% environment friendly (which isn’t bodily doable), a 1 kilowatt (kW) solar system in Melbourne would produce between 4.18kWh – 4.8kWh of energy per day, and a 2kW system would produce between 8.36kWh – 9.6kWh per day.

In actual life, nevertheless, there are effectivity losses that should be taken under consideration between the time the solar hits your panels and when it exits the system’s inverter. The desk beneath reveals tough day by day energy output figures for a variety of in style solar system sizes if put in on a north-facing roof within the Melbourne space, assuming an effectivity lack of about 25% (to be conservative).

Estimated solar panel power manufacturing in Melbourne for in style system sizes

Solar system dimension (kilowatts) Avg day by day system output* (kilowatt-hours) Annual Output* (kilowatt-hours)
2kW 6.3kWh – 7.2kWh 2,445 kWh
3kW 9.4kWh – 10.8kWh 3,686 kWh
4kW 12.5kWh – 14.4Wh 4,927 kWh
5kW 15.7kWh -18.5kWh 6,241 kWh
7kW 21.9kWh – 25.2kWh 8,614 kWh
10kW 31.4kWh – 36kWh 12,300 kWh

How solar energy saves you cash

When you might be grid-connected with no solar system, it’s important to buy your whole electrical energy from an energy retailer. Typically, you’ll pay no less than 21c for each kilowatt-hour that you just use.

Having solar panels will mean you can get monetary savings by decreasing your must buy energy from the grid – each unit of solar energy that you just ‘self-consume’ in your home is a unit that you don’t want to pay for. You can even earn credit for promoting your energy into the grid (present state minimal set at 6.7c per kWh), however you’ll save far extra money by specializing in maximising your solar self-consumption.

There are two methods to make sure you’re utilizing as a lot of your solar energy as doable:

  1. Make certain your system is the correct dimension in your home, and
  2. Know your electrical energy consumption sample and behave accordingly.


What rebates exist for solar panels and batteries in Victoria

Federal STC Upfront Rebate

The precise worth of the inducement is determined by quite a few elements akin to location and system dimension, however often works out to be about 30% of the full set up value.

For instance a generally chosen 6.6kW solar panel system would create 70 certificates (utilizing the Clean Energy Regulator’s calculator) and at a present worth of $36.9 per certificates that might result in a rebate of $2,583.

Solar Victoria Rebate

Solar Victoria is the physique the state authorities has setup handle the supply of the Victorian Government’s Solar Home Program – which gives a further rebate to the federal program to eligible households. Importantly that is along with the federal STC rebate talked about above – you don’t have to decide on between them.

If eligible, your rebate may very well be as excessive as $1,400 for solar panels and $3,500 for solar batteries. There are additionally curiosity free loans obtainable for eligible Victorians.

What about solar battery storage in Melbourne?

In common, the return on funding for solar batteries in Australia is decrease than solar panels. This is especially resulting from the truth that the price of batteries hasn’t (but) gone by way of the dramatic fall in worth that we have now seen solar panels take during the last ten years.

At Solar Choice we’re following these costs very intently and we frequently carry out an evaluation of the monetary return of batteries in our ‘Are solar batteries value it?‘ article. The quick reply is, regardless of the state authorities rebate of $3,500, for most individuals the monetary payback alone is not going to benefit the excessive value required to put in a battery.

See the beneath 3 use instances we have now examined intently to evaluate the payback interval for an optimally sized solar and battery system. Note every use case has a unique energy utilization load profile which impacts their financial savings.

User Case Solar and Battery Solution Total Year 1 Savings Payback Period Solar & Battery Payback Period Battery Only
Young Adults / Older Family 5kW of Solar Panels and a 3.5 kWh battery $890 8.3 years > 20 years
Retirees / Young households 6.6kW of Solar Panels and a 6.5 kWh battery $1,311 7.1 years 18.9 years
Big Energy User 13 kW of Solar Panels and a 13.5 kWh battery $2,262 8.9 years > 20 years

To see all of our assumptions and the methodology of this evaluation see our full article.

Why then are so many Victorians putting in batteries alongside their solar panels? For many individuals the chance to entry a $3,500 rebate is simply too good to move up, while for others there are some non-financial causes that encourage the set up of a battery. After latest bushfire seasons energy safety has risen to the highest of everybody’s minds and the one approach to maintain the lights on in your home with out putting in a generator is having a solar and battery system.

Also necessary to say that the transition away from coal power in Australia gained’t be doable with out way more battery capability. While it’s not going to be the duty of house owners to produce this capability, each little bit helps!
