The figures for average daily solar generation

Fortunately, studies have been conducted that take all of the above factors into account and give the average energy output for solar cells in locations around Australia.  These figures are given as:

The amount of electrical energy (kWh) a 1kW grid connected solar PV system will generate on an average day (kWh/kWp.day).

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 daily production of solar PV cells in Australia.

Solarpanel daily production

Data Source: PV.GC spreadsheet. based on the CEC GC Design Guidelines

The rated output is that achieved in perfect laboratory conditions.

The CEC design summary software takes these deratings into  account when predicting average for any given system.

 

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. Solar panels produce more energy in summer than they do in winter.

Electricity from the sun: Solar PV systems explained” by the Clean Energy Council

Researching this topic will reveal other credible sources, with slightly different figures.

The USA’s National Renewable Energy Laboratory’s (NREL) PVWatts tool also works for Australia (using Aussie meteorological data) and is a great resource for plugging in numbers and estimating a solar system’s output.

We encourage you to check it out.

Some exploration will reveal that it’s not quite possible to put an exact unequivocal figure on the energy you will produce from you solar cells.

 

Indeed, as Dr Anna Bruce, Lecturer at the School of Photovoltaic and Renewable Energy Engineering at the University of New South Wales informed us, different solar systems both rated at 1kW sitting side by side may produce different amounts of energy due to the quality and efficiency of their components, how the grid is functioning and how well your system deals with high temperatures. 

 

Her expert advice is that “4kWh/kWp.day in Sydney is certainly feasible if a system has optimal tilt and orientation and is running well”.

 

So the Clean Energy Council figures above act as a good guide and are one of the best and most comprehensive sources available, however due to the nature of solar, your system may produce more, or a little less than the figures given.
