10 Kilo Watt Solar System Retails For Less Than $8,000 In Adelaide

Our 3 Klilo Watt solar system was installed in June 2012 at a cost of $5,300. It is a high quality system and after a lot of research i specified the system should comprise:

  1. Suntech solar panels – 250 watt panels were installed (STP 250S). These panels represented good value back in 2012 and have a reputation for solid performance and good customer support and warranty support should it be required. Suntech heralded from research done at U.N.S.W. school of renewable energy so has at least a modicum of Australian content in them – even if its only the brainpower that went into their development
  2. An SMA inverter. SMA have captured the lions share of the Australian solar inverter market – at least for the ‘quality end’ of the market
  3. SRC Railing. railing refers to the aluminium structure that is bolted to the roof and onto which the solar panels are then installed. SRC is an Adelaide based solar rail manufacturer – not the largest but one of the best in terms of the climate and wind performance of their products. I didnt want my solar panels blowing off the roof!!!!

So, this quality system cost $5,300. I saw this week that 2 Adelaide solar companies are claiming to offer a 10 Kilo watt solar system, installed for $7,960. This is quite astounding. I did some digging and it seems that they are using ET Solar panels which have a reasonably good reputation and a Samil solar inverter. I do not have a lot of knowledge with Samil but from reading other solar forums they appear to have been represented in Australia since 2009 and claim to have a reasonable market share for domestic solar systems.

How Low Can Solar System Prices Get?

It is hard to see how much lower solar pricing can go. The market is fearing the worse from the current R.E.T. review and if the existing solar incentives are removed then the market could really collapse. Less demand for solar means further price competition (presumably), so we watch with interest.

Repeal Of The Carbon Tax – Impact On Solar Power and Renewable Energy?

Carbon Tax Repeal – Climate Change And Renewable Energy

OK. We know it. Today is not a good day for Australia with the shameful
repeal of the national price on climate pollution.

It appears that we now have climate denialist governments in power nationally and in all
States and Territories, bar South Australia and the ACT.

This is not a platform from which to build the scale of action that is
needed on climate. It is time to be clear that our job is no longer to
convince denialist governments to tweak their program at the margins.

We are now in a struggle for our lives and it is a time to support the solar energy industry and renewable energy initiatives.

We need to boot out the denialist governments and to elect governments who
will protect their people and the environment and create a clean energy future for Australia.

And by the time the denialist governments are gone, the time for slow
reform will have passed.

In Australia’s darkest hour on climate, what will get us out of bed in the
morning to build the power and commitment needed for a climate rescue?

What needs to be done now to achieve even half-measures on the environment
is so far outside of business-as-usual that we may as well commit to
restoring a climate that we know from past experience is safe for people,
civilisation and the maintenance of all species. If we have to struggle
anyway to stop the world’s onrush into climate oblivion, we might as well
work for a future that we actually want, one that will nurture us and
future generations, one that can inspire us – it is time to work to cool
the earth and restoration a safe climate.

Savings for families, claimed by Tony Abbott in Australia from the repeal of the carbon tax have been reported as being overstated.

This is a future that is in everyone’s interest in the long term and is in
interests of the vast majority of people even in the short term.

It is time to build a coalition of strong support across the political
spectrum – from right to left – that will isolate and marginalise
denialist governments and consign them and their shameful work to the dust
bin of history.

Solar Industry In Adelaide Reports 25 Percent decline In Installations

The short term outcome of the removal of the cabon tax is that electricity prices are expected to drop by around 4 to 9 percent for most Australians. In South Australia the outlook for the solar energy industry, at least short term, is not looking so rosy. John Grimes, who has been involved in the solar industry in Adelaide for 20 plus years, reports that the level of solar power installations in Adelaide has decreased by around 15 to 20 percent over the last 2 quarters (year on year). The downward ‘spike’ in electricity prices could mean that solar systems uptake will again decrease as consumers perceive the cost of power as dropping. John is very cynical about the motives behind the carbon tax repealing and sees the traditional ‘dirty coal’ producers as being behind the push by the Abbott Government to reduce the pace of growth of the renewable energy sector in Australia.

Solar Panels Systems Are Here To Stay

Johns’ view is that solar panels systems are likely to maintain their long term viability regardless of todays electricity pricing. Solar systems have a typical life expectancy of 25 to 30 years as detailed on his solar panels Adelaide website.
He sees the global impact of carbon pollution as a virtual guarantee that there will have to be concerted efforts at all levels of Government to mitigate carbon based climate change over the next 20 years. Adelaide and South Australian residnets have lead the way in installing solar power as a way to demonstrate their support for clean energy and cut their interdependence on the coal and gas based electricity supply in South Australia. Solar panels systems have a zero carbon emission footprint and the so called ‘energy inputs’ into the construction and manufacture of solar panels is generally quoted as amounting to less than 18 months their energy output, meaning that they are greatly carbon ‘positive’ in their manufacture and operating life time.

Carbon Tax Repealing Is Only A Blip In The Renewable Energy Debate

So even though the carbon tax is now officially gone, we see the future for solar power and renewables as remaining very strong – viewed over the medium term. Solar systems are becoming more efficient and the cost of solar continues to decrease year on year. It is inevitable that the days of ‘carbon’ based energy production is limited and we remain optimistic for the clean energy future.

Magnesium Chloride – Safe Cheaper Solar Panels?

The race is on to develop solar panels that offer greater energy yields at lower prices in order to match or lower electricity production costs relative to carbon based electricity production, like the coal fired power stations produce currently in Victoria’s Latrobe valley.

This article from the BBC reveals that Liverpool University have found that by using Magnesium Chloride in solar panel manufacturing, they can take the next step in cost reduction and creating a cleaner manufacturing process for solar panels – Read the article here.
