Solar power system information for Perth

Grid connect solar power is particularly popular in the Perth City Council area, because it is home as per 2018 (ABS) to 2,164 people on the age pension. Solar power, as per many solar installers, selling experience is popular amongst the more mature population as it can deliver retirement savings.

The total land area of the Perth City Council area is 11,377,000m2, which if we would cover the whole Council area in LG NeON 2 360W solar panels lying flat on the surface, would allow 6,583,912 LG360 N1C-N5 panels (1.728 m2 per panel) to be positioned on this surface. This would then allow for a solar total system size of 2,370,208kW which would theoretically generate up to 4,047,091,290kWh per annum and if we take 19kWh as an average family consumption per day, could power the homes of 583,574 families each year.

Since 2010, when solar systems became a mainstream consumer item, 404 solar power systems have been installed locally with a total size of 2,860kW. This means the average system size in your area is 7.08kW, which is obviously quite a bit more, than the 6.6kW system size which is nowadays the average residential solar system size. This means there are quite a few of the older style small (installed around 2008 to 2012) 1.5 and 2-3kW solar power systems installed locally.

You can also see how solar system installations have grown exponentially in Australia and for the postcode 6000 the number of installations in the past two decades are:

In regards to the total kW installed in postcode 6000, the annual numbers over the past 2 decades clearly show how system sizes have increased considerably.

Given that the wider suburb has 8,851 people living here as per 2016 (ABS) this means each citizen has 323Watt of renewable energy in a statistical sense. Please note in Australia as a whole the average renewable energy as at mid 2020 was 498 Watts per person. So Perth's renewable efforts are less than the Australian overall effort.

Perth and the overall postcode of 6000 in total has 5,692 rateable properties, many of which are houses. With 404 solar systems installed locally as at April 2020 - this means every 15th rateable property has a solar system.

Another statistical way to express the renewable credentials of Perth is that in 100 properties approximately 8 have solar power installed. This means there are considerably less properties with solar power than the Australian average of 25 properties per 100 - as at April 2020.

Based on an overall total of 2,860kW of installed solar panel system capacity in Perth, 13,384kWh of renewable energy is being produced each day on average (enough to power the equivalent of 704 homes - based on the assumption of the average consumption of 19kWh per home per day). With an average retail price and feed in tariff mix assumption of a value of 19c per kWh the residents in postcode 6000 produce for their annual solar renewable energy generation of 4,885,109kWh effectively generate annual savings in their electricity bills of $928,170 per annum. That’s a decent bundle of renewable energy savings due to the power of local solar energy systems.

Given that LG solar has, as at May 2020, sold the equivalent of 1,200,000 solar panels at an average wattage of 300W in Australia since 2010, this means the equivalent of 54,545, of 6.6kW LG solar systems would have been sold by June 2020 in Australia and NZ. This means around 5% of residential solar systems installed in Australia and NZ feature high quality LG solar panels of the Mono X and NeON range. If the Australian average of installed LG solar systems being approximately 5% would apply to Perth, then approximately 21 homes in the Perth area have a good chance to have high quality LG solar panels.

Daily/Monthly system output estimates

Some of the most popular residential and small commercial solar system sizes are 4kW, 6.6kW, 10kW, 12kW and 15kW. For example 19 x LG NeON 350W panels make a 6,650kW system. Below is the estimated output you can expect from a number of the most popular solar system sizes in Perth, as long as the system is a solid quality solar power system, installed by a top technician like an LG solar installation partner with no overshadow issues.

Information about the local feed in tariff in Western Australia

Your installed solar power system will supply your home with electricity during the day like for the washing machine or TV, but if your renewable energy system produces more than you use in the house, the surplus electricity will be exported into the grid. Perth solar owners can be paid for surplus renewable electricity generated. You will be paid a feed in tariff (FIT) from your energy company. The going rate in Perth for feed in tariffs as at April 2020 is between 7cents and 21cents per kWh. As the payment varies between energy retailers we strongly recommend to shop around between energy retailers to find the best feed in tariff rate. It can make a big difference to your financial benefits.

Solar savings estimates for Perth

If you have a 6.6kW solar power system in Perth and a self-consumption rate of 55% and you export on average 45% of the system generation, with an electricity cost of 28cents and a feed in tariff rate of 12cents in this example then in the 1st year of system ownership a Perth solar system owner can expect an estimated saving of $2,298 per annum.

With an estimated annual panel degradation of 2% for the 1st year and 0.3% after the 1st year a total 25 year saving of $55,392 could theoretically be achieved. This estimate only applies if the system is maintained well including having the inverter kept in working order over the 25 years. You can undertake more ROI calculations by using the LG solar savings and payback calculator which can be found here.

Solar batteries

Solar energy batteries can work seamlessly with a solar panel and inverter system. It is expected by industry experts and the solar installation industry as a whole, that batteries in future years will be increasingly added to solar systems, as volumes of battery production grow and prices hopefully fall.

Currently in Perth the solar system renewable energy battery installation numbers are not published by the Clean Energy Regulator for the suburb specifically, but we know via the Clean Energy Regulator in all of WA the solar battery installation numbers as at April 2020 are as follows going back to 2014:

Total number of solar batteries installed in Western Australia (cumulative)

How to best install your panels

For the best output results solar panel energy system in Perth should see the panels installed facing North for the highest output. Nevertheless if your consumption is more after 2pm when for example teenagers come home and when you run the air conditioning in the afternoon, a North West or West facing solar panel system can also give you excellent results.

If you have a high electricity consumption from for example cooking and baking in the morning, consider to install some panels facing East to maximise output.

The ideal panel angle the solar panel should be positioned at is in the range of 17 degrees to 27 degrees tilt, with 22 degrees being ideal. Nevertheless a less than ideal system tilt, like for example on a flat roof or only a 15 degree tilt, means regularly only a loss of approximately 5% of overall generation.

Therefore instead of paying for high engineering costs to frame the panels the ideal way, just add a few more panels to make up for the less than ideal angle your roof structure might be presenting. LG Electronics makes a wide range of high quality solar panels. Our products can be found here and our install partners can be found here - just type in your postcode.

Council solar system rules

As at April 2020, there are no special requirements involved with installing solar power in the Perth City area. We recommend you check with the Perth City Council regarding any potential local solar system installation rules before you give the go ahead. Usually your local installer is also familiar with the Perth City Council rules - so ask him/her for advice. The correct link to your council info can be found here.
