Government investment in solar is set to continue with both sides of the Australian government agreeing to '...retaining the Renewable Energy Target now set at 41,000 gigawatt-hours per year by 2020.' Big energy companies such as AGL are steadily investing in solar farms in outback locations of Australia.

Printing Solar Cells Forum

PRINTING SOLAR CELLS (September 1st, 2013)


BJ White Electrics staff participated in an innovative forum about printing solar cells. Recently, Dr Scott Watkins at the CSIRO has developed a method of printing solar cells by using a commercial screen printer. See this video by clicking on this link http://www.csiro.au/Portals/Media/Printing-Australias-largest-solar-cells.aspx#video







The cells are printed with an ink. The cells are then simply laminated using a common laminating machine. This process has taken up to 8 years to develop.

Future applications for its use are quite promising. We will be able to install these cells on buildings, windows, and many other surfaces. This thin film PV will spawn a new way of creating solar power. It is likely that you will see this type of power being used to light magazine racking, in-store advertising and stands in the near future. BJ White Electrics is proud to be associated with these cutting edge innovations developed by the CSIRO.

Rapid uptake of solar systems

Rapid uptake of solar panels puts dent in electricity market, report shows

Updated Mon 5 Aug 2013, 2:58pm AEST

A new report shows Australians have pounced on ways to save on their electricity bills by installing solar panels at an extraordinary rate.

The Climate Commission's Solar Energy report found more than 10 per cent of Australians, or 2.5 million people, use solar power for their homes.

It found there are now more than 1 million rooftop solar systems in Australia, up from 8,000 in 2007, with most uptake in the mortgage belt suburbs of Queensland, New South Wales and Victoria.

Climate Commission chief Tim Flannery is calling it "a solar revolution".

Key points

  • Report found 2.5 million Australians use solar power in their homes
  • Now more than 1 million rooftop solar systems in Australia
  • Most uptake in the mortgage belt suburbs of Queensland, New South Wales and Victoria.
  • Cost of production of solar panels has declined 80 per cent in the last four years

"The things that have happened over the last five years in solar and in Australia weren't anticipated by anyone," he said.

"If you look at the government projections as to how the solar industry was going to develop, they were suggesting it would grow to the point it is now only by 2030."

Professor Flannery says it is just the beginning, with solar thermal power the next frontier in the renewable energy revolution.

"It has added up to a revolution because what it’s done is put in the hands of the people the capacity to generate their own power," Professor Flannery said.

But he says it is not wealthy people installing solar panels.

"They are people on fixed incomes, particularly who don't like this idea of getting a bigger and bigger electricity bill every year, and people with large mortgages," he said.

Autumn – A Great Time For Solar Electricity Generation


Autumn solar power
National solar provider Energy Matters says autumn is a great time for solar – with cool days and clear skies, solar power systems will be operating at optimum efficiency.

One of the many myths about home solar power is that the hotter the day, the more electricity is produced. In fact, it's the opposite.

Heat is the enemy of a solar panel – it reduces efficiency and the lower the quality of a panel, the less power it will generate on a hot day. The heat issue is an example of why not all solar panels are equal. However, the length of sunlight exposure over the longer summer days goes some way to addressing this issue.

Autumn is probably the best time of year in terms of power generated per sun-hour – the cooler conditions allow panels to achieve their best efficiency.

The 5kW system can return a financial benefit of an estimated $1,042 – $2,450 annually depending on installation location and electricity consumption profile; meaning payback time can be just a few years.

THE national trend of plunging solar feed-in tariffs intensified yesterday when Victoria slashed its subsidies to rein in spending and to account for soaring demand for renewable energy.

Victorian Energy and Resources Minister, Michael O'Brien, released figures showing the original Labor-era tariffs for providing surplus power to the grid would cost Victorian taxpayers nearly $500 million by 2024.

He said a core argument against big tariffs was that all energy users were effectively propping up those consumers who had signed up to healthy deals.

The rising price of electricity, he said, was encouraging a rush of consumers to sign up to solar power and not even big falls in feed-in tariffs was curbing demand.

"Victoria saw a 33 per cent increase in solar connections for the first six months of 2012 compared to the same period in 2011, despite the feed-in tariff stepping down from 60c/kWh to 25c/KWh," he said. "This demonstrates that it is the falling cost of solar and the rising price of electricity that is driving uptake, rather than feed-in tariffs.

"We have avoided the boom-bust experience in other states that eliminated all feed-in tariffs without warning."

An analysis by The Australian shows a clear national trend towards either eliminating or markedly cutting the size of payments for people whose solar energy production exceeds their domestic needs and is then fed back into the power grid.

Mr O'Brien said the government would accept a Victorian Competition and Efficiency Commission finding that the feed-in tariff should be extended to all sources of low emission energy generation.

Clean Energy Council Policy Director, Russell Marsh, said the national solar industry was preparing for a backlash due to the policy change.

"This change could have a serious negative impact on an industry that has been delivering major economic benefits to the state," Mr Marsh said.
