The most comprehensive source of this information is the clean energy council the body that the australian government charges with accrediting solar cells inverters and installers.
Average solar panel output per day australia.
A panel rated at 250 watts will likely only produce 186 7w of electricity per hour of sunlight.
The amount of power output kwh a 5kw solar pv system grid connected will produce on an average day is 25c kwh.
If panels point straight west or east are tilted to low or to high a further reduction in output of up to 15 can occur.
So if you have a 7 5 kw dc system working an average of 5 hours per day 365 days a year it ll result in 10 950 kwh in a year.
However keep in mind that there are many factors at play here so this is really only a rough estimate.
On average a normal household will use around 37 kwh per day.
So if you have solar panels that each produce 1 kwh of power per day you would need a full 37 solar panels to fully power your home.
A 2kw system should output on average 7 8 kwh per day and a 10kw system 39 kwh per day.
Solar output for melbourne is reasonably good in the area because of its location and weather conditions.
The infographic below shows the effect of efficiency factors on panel output.

That s enough energy to power some small appliances without too much issue but if you want to cover the energy used by your property s climate control systems or large cooking appliances you ll need more solar panels.
For site specific rather than general solar system outputs please request a site inspection and discuss the matter with your lg solar dealer.
It is estimated that 1kw of solar panels can generate up to 1321kwh of electricity annually and on average 3 62kwh of electricity per day see the calculator on this page for more details.
A typical australian house consumes around 18 kilowatt hours kwh per day so a 1 2kw system displaces an average of 25 40 of your average electricity bill.
In the example above the solar panel is producing 1 5 kwh per day which ends up being about 45 kwh per month.
This is an overview on how to understand how much energy your solar system will produce and overall solar panel output.
The clean energy council advise that in sydney a solar system should on average output 3 9 kwh of energy per day for every kw of solar installed taking into account the seasons and the weather.
Solar panels produce more energy in summer than they do in winter.
On any given day this figure could be extremely different.
