For people who may be unaware of the different names in use, for rooftop photovoltaic electricity generation systems, they are also known as "solar panels", and, "solar electricity systems", and, "solar panels systems", and their purpose is to convert available sunlight (apparently, they do not work with moonlight, which is unfortunate, exspecially on nights with a clear sky and a bright full moon), into usable electricity, that may, when an excess is generated, be input into "the electricity grid", and/or, now that they have apparently been legalised, battery storage systems.

Rooftop solar producing more energy than WA's biggest turbine
By Anthony Stewart
Updated January 05, 2016 10:52:23
Rooftop solar panels in the South-West Interconnected System (SWIS) in Western Australia are now producing as much energy as the state's largest power turbine, according to research from Curtin University.
SWIS stretches from Kalbarri north of Perth to Ravensthorpe in the state's south, taking in the Perth metropolitan area.
Curtin University sustainability professor Peter Newman said 20 per cent of homes across the grid have rooftop solar panels installed.
"We are in the extraordinary position of saying that Perth [SWIS] now has rooftop solar as the largest supplier of electricity, it's the biggest power station in WA," he said.
"It's nearly 500 megawatts and it's growing rapidly, by 2020 we could have half of Perth's [SWIS] households with rooftop solar."
SWIS, which includes coal, gas, wind and solar generation, has the capacity to produce 5,300 megawatts of power, but it only used roughly two thirds of that at its peak in 2014/2015.
Not including solar, coal makes up about 50 per cent of WA's energy production mix, while gas represents 42 per cent and wind 6.3 per cent.
Professor Newman said the state's electricity utilities needed to rapidly adapt to the growth in solar.
"They didn't predict it, they have all these contracts for coal and gas that go 20 or 30 years and they have even got an old power station out of mothballs, fixed it up, but never turned it on," he said.
"Despite the boom times we actually reduced our power consumption during this period because people are just not needing it if you've got the PV's [photovoltaic] on the roof."
Energy utility Synergy has been contacted for comment.
Batteries to drive solar boom
Rooftop solar's biggest weakness has been its inability to supply power once the sun sets.
This can be addressed with the installation of large battery systems that allow households to store solar energy for use in peak periods.
Clean Energy Council policy manager Darren Gladman said until recently battery storage systems had been too expensive for the average consumer.
He said household batteries would become increasingly common with big producers like billionaire entrepreneur Elon Musk's company Tesla entering the market.
"In 2016 the onset of batteries and entry of Elon Musk to the market is going to really change the way we think about energy," he said.
"We are not just going to think about producing energy from solar, but producing energy and storing it."
Mr Gladman said Australia would become a global leader in the rollout of battery technology.
"Because we've got so many households with solar on the roof, reasonably high power prices and great sun of course, it means we are a prime market," he said.
"So that makes [us] one of first markets the likes of Elon Musk, but also other companies that sell batteries, are targeting."

In the last couple of days, the ABC online news web site has published the news report at http://www.abc.net.au/news/2016-01-20/tesla-powerwall-solar-battery-system-popular-mandurah-in-lead/7102494?section=wa
One thing that perhaps, does not occur to many people, that had occurred to me, a few weeks ago, is that, regarding the bit in the news report, about reducing the demand for grid electricity, during summer;
"
The burgeoning popularity of rooftop solar is also increasingly
reducing peak demand on the electricity network servicing Perth,
according to the Australian Energy Market Operator.
Its data shows peak demand on the hottest day in Perth five years ago
was 3735 megawatts, reduced by 19MW due to solar PV systems.
In 2013, solar PV reduced peak demand by 84MW on the hottest day of
the year, and in 2015 the figure more than doubled to 187MW.
"
is that one probable effect of the uptake of rooftop domestic photovoltaic systems in WA, is that it is now, some years since we had to suffer the rolling electricity blackouts that were imposed because Western Power would not provide sufficient electricity to cope with people going home from work in the summer, and turning on their air-conditioners.
We, the people with the rooftop domestic photovoltaic systems, have apparently overcome the electricity supply shortage that had caused the rolling electricity blackouts in past summers, in WA.
That is simply one of the many benefits of the rooftop domestic photovoltaic systems.
At http://d3bo5ucoqkgs8h.cloudfront.net/uzOHN/1/?abcnewsembedheight=430 is shown that the Armadale postcode, 6112, is the third highest postcode in the state, in terms of the number of small scale (non-commercial) photovoltaic systems installed in 2015, with 603 installations, and, in terms of the generating capacity, again, the third highest, with 2.498MW of generating capacity, installed in those systems.
That the 6112 postcode, is the third highest in the state, for these two ratings, is interesting, given that it is said to be one of the lower socio-economic postcodes in the metropolitan area. Maybe, the greater necessity to be careful with what funds a household has available, has led to wise investment, to reduce ongoing living expenses, by using solar energy, quite apart from the environmental aspect of using clean energy, rather than energy created by burning stuff and causing increasing pollution.
Also, at http://www.cleanenergyregulator.gov.au/RET/Forms-and-resources/Postcode-data-for-small-scale-installations is the information that, for 2015, for the whole of Australia, 130,253 small scale photovoltaic systems were installed, with the cumulative number of such installations, for the country, being 1,498,159, and, those equivalent numbers, respectively, for WA, being 19,055 and 194,472.
Now, a number of aspects to these quantities, arise.
The first, is that, for the numbers of installations in the 2015 calendar year, for both Western Australia, and, for the country as a whole, that involves alot of both Western Australian, and, otherwise Australian, employment, which is good for both the WA and federal economies.
If you visit my residence, you will likely see the sign on the fence, which sign states "Vote Jobs - Vote Solar", and, with 19055 new "small scale" rooftop photovoltaic systems, being shown as having been installed in Western Australia, in the 2015 claendar year, that shows that the installation and use of domestic rooftop photovoltaic systems, provides alot of employment, for alot of people, in Western Australia.
The second aspect to the above data, is that, in terms of WA, which has a state parliament that is hostile to photovoltaic systems, 194,472, as the cumulative number of photovoltaic systems installed, involves alot of voting power, especially when the state parliament considers imposing extra financial penalties on households with domestic rooftop photovoltaic systems.
This is quite apart from the missing quantities of the total available electricity generating capacity, and, at http://www.cleanenergyregulator.gov.au/DocumentAssets/Documents/Postcode%20data%20for%20small-scale%20installations.xls is shown that, for the Armadale postcode of 6112, alone, as at 01/01/2016, the postcode has a generating capacity of 13 MW, from photovoltaic systems.
I have yet to find the total generating capacity, for all of the listed small scale photovoltaic systems in Western Australia, and, when I do find that information, I intend to also publish that information here.
The use of rooftop photovoltaic systems, is an important part of Australia, including but not limited to, the environmental and economic aspects, and, changes need to be implemented, to encourage increasing the usage of rooftop photovoltaic systems.
One of the changes that are needed, for both households who already have rooftop photovoltaic systems, and, for people who may be considering getting installed, rooftop photovoltaic systems, are changes to state and any higher, legislation, including to both planning legislation, and, the notorious tree legislation, so that any property owner who has a tree on the property, is legally and otherwise, responsible and liable for any loss or damage attributable to the tree, including, but not limited to, where the tree casts shadow on a residence on a different property, so as to interfere with the use, or, prospective use, of rooftop photovoltaic electricity generation, and/or, otherwise casts shadow on a residence in a property other than the property on which the tree stands, so as to cause increased energy consumption, such as extra heating being required during colder months, due to shadow being cast by the tree, on the residence, and, similarly, with planning, disallowing building development, including modifications, where such development would cause or increase shadow being cast on a building on a property other than the property on which the building is being developed, similarly, so as to interfere with the use, or, prospective use, of rooftop photovoltaic electricity generation, and/or, otherwise casts shadow on a residence in a property other than the property on which the building is being developed, so as to cause increased energy consumption, such as extra heating being required during colder months, due to shadow being cast by the change caused by the building development, on the residence that is not on the property on which the building being developed, stands.
An advocacy body exists, in the eastern states, regarding solar energy usage. The organisation is named Solar Citizens. It is the owner and supplier of the sign on the fence of my residence. The organisation's web site, is at http://www.solarcitizens.org.au/ .
That web site has an online petition to try to prevent the state parliament from further increasing the financial penalties imposed on households with rooftop photovoltaic systems in Western Australia. Western Australia is shown as having 194 thousand small scale photovoltaic systems installed. Apparently, as at 22 January 2016, only 6700 people have signed the online petition to stop us getting further penalised for doing the right thing. A question is, "How many households with rooftop photovoltaic systems, in Western Australia, are aware of the online petition?"
We need an organisation, such as Solar Citizens, or, a branch of such an organisation, in Western Australia, to advocate for solar energy usage, and, to advocate for increasing solar energy usage, and, other clean energy usage, in this state, and, to be more active, in advocacy in favour of the use of solar energy, and, other clean energy, in this state..
In the last few days (and, including today), Perth, Western Australia, has been experiencing a heatwave, which, with the use of air-conditioners, to ameliorate the heat, has lead to record levels of electricty demand, in the heat of the day.
At http://www.watoday.com.au/wa-news/perth-weather-42-degrees-on-monday-sees-city-break-alltime-power-record-20160208-gmov9v.html is an article, which includes

Later on Tuesday all eyes will be on Western Power, after Perth
smashed its power demand peak record on Monday evening.
At 3.30pm Monday, Western Power set a record for demand peak, topping
the old mark of 4068 megawatts set in January 2012.
By 5pm, with the temperature still 41.7 degrees, the demand was up to
4264 megawatts. Western Power compared the electricity demand to that
associated with Domain Stadium hosting 160 football games.

and still, we had no blackouts due to the heatwave.
I had sent an email message to the publisher, advising that I woinder why the article that was published yesterday, did not include reference to the respective amounts of electricty generated, and, input into the grid, from rooftop domestic photovoltaic systems, for the two electricty demand peak times mentioned in the article. I am interested to find wehether I get a reply to that.

Australians must brace for hotter, longer and far more frequent
heatwaves thanks to climate change, scientists say.
Leading climate scientists say extreme prolonged heat is becoming the
norm in Australia, where the number of annual heatwave days has risen
markedly over the past 60 years.
The warning comes after a series of scorching summer heatwaves around
the country, including one in Perth where temperatures are expected to
stay above 40C until at least Thursday.
Climate scientist Sarah Perkins-Kirkpatrick says the extreme events
will only continue to increase.
"Those really rare heatwaves we might have only seen once every 20
years for example, might occur now once every two years," she said on
Tuesday.
"They will certainly be occurring lot more often than what they used
to had climate change not occurred."
Bureau of Meteorology senior climatologist Blair Trewin agreed, saying
there had been a strong increase in weather events involving extreme
heat and a decline in the number of extreme cold events.
Dr Perkins-Kirkpatrick said weather data from the past 60 years showed
a marked increase in the number of heatwaves.

On Monday, the temperature soared to 42.5 C (108 F) in Perth, which
was the hottest February day in the city since 1997, according to the
Australian Bureau of Meteorology. Western Power reported that their
system usage reached an all-time high of 4,174 megawatts on Monday,
breaking the previous record from January 2012.
The extreme heat will continue on Tuesday and Wednesday with highs
expected to reach around 43 C (109 F) both days.

Given that we have not yet suffered electricity supply blackouts due to overloading due to the heatwave, I am interested to know respective quantities for each of the total amount of electricty generated, and, the amount of electricty input into the grid, from domestic rooftop photovoltaic systems

Air-Conditioning, Heatwaves And Solar Power
January 27, 2015Energy Matters
There are now around 6.7 million households with air conditioners
installed in Australia, compared to only 1.9 million in 1990 – and
solar power systems are helping to alleviate the strain the comfort we
demand places on electricity networks.
Approximately a quarter of the investment by electricity networks –
eleven billion dollars – has gone towards constructing capacity to
cope with supplying power to all this air-conditioning on a handful of
days each year. A 2kW air conditioner may only cost around $1500 to
purchase, but imposes costs on the energy system of up to $7000.
While there may be 6.7 million air-conditioned households across the
nation, the number of units is significantly higher as some homes have
multiple installations.
An information sheet recently released by the Energy Supply
Association of Australia (ESAA) states that on a typical January day,
operational demand in Victoria reaches around 6,643MW. When heat waves
hit, this already high level goes through the roof. For example, on
January 29, 2009, operational demand reached 10,576 MW.
Another sizzling day was on January 16, 2014 when demand reached 10,307 MW.
But why was it less in 2014 given there would have been substantial
growth in air-conditioners between 2009 and 2012?
Part of the answer has to do with solar panels.
During the 2014 heat event, solar accounted for around 4.5 per cent of
generation during the time of peak demand in SA and 2.4 per cent in
Victoria.
"This means total peak electricity demand in both states was almost
certainly significantly higher in January 2014 than the all-time
record, but the effect of increased penetration of solar was to keep
demand below the levels of demand set in 2009," says the ESAA.
Not only did solar power help lighten the load on electricity
infrastructure, it did so incredibly cheaply too. Peak power plants
supply electricity at short notice; but the electricity generated is
very expensive, costing up to $12,500 per megawatt-hour - $12.50 per
kilowatt-hour wholesale.
The solar revolution is also changing the timing of peak demand;
particularly in South Australia. While Queensland has the most solar
capacity installed, South Australia has the highest penetration rate
of solar panels in Australia, with a quarter of the state's homes
having solar panels.
In South Australia, peak demand time is being pushed deeper into the
evening. Over the last couple of years, peak demand has shifted from
5-5.30pm to 6:00 PM and 7 PM respectively.
ESAA's Heatwaves And Electricity Supply factsheet can be viewed here
(PDF). The ESAA is the peak industry body representing the stationary
energy sector in Australia.
"
I looked at the ESAA document, and, downloaded a copy, and, in an email message that I sent to the contact person for the document, I asked why the document did not include respective information for Western Australia, and, whether a current, or, more recent, updated version of the document, would be available.
The document is interesting, and it is worth reading, but, a newer version, to both bring the content up rto date, and, to include alll of the states, is needed.
Unfortunately, my email message to the contact person regarding the
document, bounced, as "addressee unknown" , and, subsequent
investigation revealed, on the still operational (and, now, out of
date) web site for the ESAA;
"
From 1 January 2016, the esaa secretariat will no longer operate. The
change follows a decision by the member companies of the esaa, Energy
Retailers Association of Australia (ERAA), the Energy Networks
Association (ENA) and Grid Australia to reorganise and rationalise
their representative associations to better reflect the changes
underway in the energy industry.
"
So, the ESAA has gone. I note that its board included a representative from Synergy, which has an aversion to domestic rooftop photovoltaic systems.
Now, in the context of all of this, I revisited a copy of the document cited above, as being published at http://www.cleanenergyregulator.gov.au/DocumentAssets/Documents/Postcode%20data%20for%20small-scale%20installations.xls and, it occurred to me that, by using what little spreadsheet skills I remember, given that the postcodes for Western Australia, are, to my knowledge, the 6000 to 6999 range of postcodes, which occupy rows 2222 to 2651 of that spreadsheet, and, given that the column BA of the spereadsheet, has the heading "SGU Total Output in kW Total, I obtained a sum of the values of the cells in that column, for rows 222 to 2651, inclusive, and got a total, for the total rated output for small photovoltaic systems, for Western Australia, as at the end of 2015, of just over 535MW, which, to me, is a phenomenal amount of electricity.
Now, I realise that, from my understanding of the way that photovoltaic panels work, the efficiency may drop slightly, as the ambient heat increases, but, it appears to me, likely that, when the record electricity demand occurred, we people with domestic rooftop photovoltaic panels, were likely contributing about 10% of the electricity supply, including both to ourselves and the grid, avoiding the need for electricity supply blackouts due to record peak demand for electricity, due to the heat.
I have today, found the existence of an organisation in Australia, named the Australian Solar Council, which includes solar energy equipment providers, as well as individuals, as its members, and, that organisation has the published objective; "The Australian Solar Council exists to promote scientific, social and economic development through the environmentally sound use of solar energy.". But, on their web site, I found no information resemblig what I have published above. And, while that organisation apparently has a WA chapter (for which, the web page has apparently not been updated since 2011 (as at the time of me writing this, on 10 February 2016) ), once again, the web site does not include any information about the number of domestic rooftop photovoltaic systems (classed above, by the spreadsheet cited, as "SGU's", I believe), installed in Westewrn Australia, by postcode, and, for the whole state, and, neither, for those two instances, does that web site include (that I could find), publication of the total possible generating capacity, of domestic rooftop photovoltaic systems. And, especially, the web site makes no reference (that I found) to the current heatwave in Perth, and the resultant record electricity demand, and the impact of the domestic rooftop photovoltaic systems (and all of the photovoltaic systems) that are installed, on the demand for grid electricity, and, the alleviation of the need for electricity supply blackouts, due to the use of the photovoltaic systems. So, I call on the Australian Solar Council, to make its web site more functional (instead of the "froth and bubbles", that it is, and, publish pertinent information, that is kept as up to date as possibl;e, about the status and benefit of photovoltaic systems (in addition to other solar energy usage, such as solar hot water systems. The organisation is apparently, a big and rich organisation, but, it appears to be missing its point, by its web site not being as functional and informative, as it should and could be.
And, with a federal election due in 2016, and, a state election (for WA) due in 2017, we need a npolitical party that will start to do the right thing, like the federal government, through a Clean Energy Finance Corporation, offering interest-free loans to householders, to install photovoltaic systems and storage batteries.
And, the state parliament should ensure that, given that people who have photovoltaic systems installed, are required to have installed, with a fee, "bi-directional" electricity meters, people who have photovoltaic systems installed and in use, are only charged for net electricty usage for all electricity bills; so that the "bi-directional meters" are used to determine the ifference between the energy rtaken from the grid, and, the energy put into the grid, and people are only charged for the difference, with the amount of benefit (currently about 7 cents per kilowatt-hour), paid wehn the net difference, is a surplus; when the electricity put into the grid, exceeds the electricity taken from the grid, with this applying for the billing cycle. After all, that is what we signed up for, but, Synergy concealed and changed the contract that we accepted when we got photovoltaic systems installed, to deprive us of what we siugned up for. That needs to be fixed - both, so that people who have phovoltaic systems, have a hard copy of what they are signed up for (other finance companies, have to provide that, but, not Synergy...), and, so that the "bi-directional meters" that we are required to pay to have installed, actually do what they are supposed to do, according to their name.
And, this is inaddition to fixng the Tree Act, and, planning laws, so that a person or body, can not be allowed to inhibit or obstruct the acces of another property, to solar energy.

Renewable energy target of 50 per cent would create 28,000 jobs, says Climate Council report
By Lucy Carter
Posted June 15, 2016 15:04:36
If Australia's renewable energy target was changed to 50 per cent by 2030, 28,000 jobs would be created, according to a report released today by the Climate Council.
CEO Amanda McKenzie said the report looked at economic modelling and compared Australia's current trajectory of 34 per cent renewable energy by 2030, to a future where 50 per cent of the nation's energy came from renewable sources.
"So nationwide if we had a 50 per cent renewable energy by 2030, there would be 28,000 new jobs.
"And the story's the same across the country in every state and in rural and regional Australia."
The modelling was carried out by independent analysts Ernst and Young and indicated that many people in coal industry jobs could be retrained and redeployed.
Ms McKenzie said Australia was the "sunniest country in the world and one of the windiest," so there were opportunities for renewable energy across the country.
"But for communities like the Hunter Valley or the Latrobe Valley in Victoria, we need to make sure that the transition away from coal to renewable energy is planned and there is a clear repurposing of roles in those areas," she said.
She said while the renewable energy options were there, the question of ensuring the policy setting was right was important.
"The good news is that rooftop solar PV, for instance, is jobs that would already exist in the area that people live and work today," Ms McKenzie said.
"There's also then jobs in regional and rural Australia with large scale renewable energy, and that sends construction operation maintenance of those plants in the longer term.
"So there is a huge potential for jobs in a whole range of areas around Australia."
Key points:
Report says people in coal industry jobs could be retrained
There are opportunities for renewable energy across Australia
Clean Energy Council says policy settings must be right to ensure jobs
Political support was "essential" to ensure growth in industry

Statistics as at 16 June 2016
I have just revisited the spreadsheet published at http://www.cleanenergyregulator.gov.au/DocumentAssets/Documents/Postcode%20data%20for%20small-scale%20installations.xls and I found some data for March, April, and May 2016, and so I extracted the following data.
For Western Australia (postcodes 6000 to 6999), in March, April, and May 2016, 1657 new domestic rooftop photovoltaic systems are shown as being installed, with a rated generating capacity of 8.316MW. for March, 1444 new domestic rooftop photovoltaic systems are shown as being installed, with a rated generating capacity of 7.069MW. for April. and, 1083 new domestic rooftop photovoltaic systems are shown as being installed, with a rated generating capacity of 5.149MW. for May, giving a cumulative total of 203,541 domestic rooftop photovoltaic systems installed in the state, with a generating capacity of 579.20MW.
For the whole of Australia (all postcodes listed), in March, April, and May 2016, 9446 new domestic rooftop photovoltaic systems are shown as being installed, with a rated generating capacity of 48.347MW. for March, 7633 new domestic rooftop photovoltaic systems are shown as being installed, with a rated generating capacity of 38.897MW. for April. and, 4965 new domestic rooftop photovoltaic systems are shown as being installed, with a rated generating capacity of 25.372MW. for May, giving a cumulative total of 1,548,345 domestic rooftop photovoltaic systems installed in the whole of Australia, with a generating capacity of 4,916,271MW.
Note: The quantities for the March and April months, will seem disproportionately greater, as, with my retrieving the data later than usual, for those respective months, the data from the source, will me more complete, as mentioned below.
Think of all of the employment that is involved, in installing so many domestic rooftop photovoltaic systems.
Please note: Regarding information extracted from the spreadsheet published at http://www.cleanenergyregulator.gov.au/DocumentAssets/Documents/Postcode%20data%20for%20small-scale%20installations.xls , that the data stated here, is as at the time of the data extraction, and, so, if cumulative totals to dot appear to correspond with previous cumulative totals plus increments, and, if data extracted at a particular time (/date), are not the same as the data for the criteria, at a later date, it may be due to the records at the source; the Clean Energy Regulator, having been progressively updated, due to an ongoing flow of paperwork, and thence, data, into the Clean Energy Regulator. So, the data that I post here, is the data that I have viewed as at the date and time of me extracting that data, and, it may change, as the Clean Energy Regulator updates its records, due to incoming data.
Whilst the above material, relates to solar energy, the author and this document and this web site, also strongly support and advocate the expansion of other forms of clean energy usage, including wind energy and hydroelectric energy, to replace the production of energy through combustion and nuclear reactions.
Remember: Increasing solar energy usage, increases paid employment involved in manufacturing and installing solar energy usage system components, which now include battery systems for storing electricity generated from solar energy, and, increasing solar energy usage, reduces household energy bills, and so cuts household costs, and, is good for the environment.
So, ask all of your state and federal members of each house of parliament, and, all of the candidates for each, what they are doing, and, what they will do, if elected, to encourage and assist in increasing the usage of solar energy, and, making it accessible to every household. Your vote counts.
