AC Solar Panels (microinverters) : The #1 Solar Trend to watch for in 2012?

Will 2012 be the year of the AC Solar Panel?

Before answering that question I should probably explain exactly what an AC Solar Panel is…

An AC Solar Panel converts sunlight to AC electricity at the solar panel.

 

What is an AC Solar Panel?

The short answer is: An AC Solar Panel is a solar panel that takes sunlight in and spits AC (Alternating Current) electricity out. This compares to a “conventional” DC Solar Panel which takes sunlight in and spits DC (Direct Current) electricity out.

AC Electricity is the type of electricity you need to power the appliances in your home. DC panels need a Solar Inverter to convert the DC electricity to AC. The big advantage of AC panels is that there is no need for an inverter to do that conversion, so you have a really simple design, a simpler installation, and adding extra panels becomes almost plug and play.

Will your solar power system protect you from power cuts?

Power Cut 17-02-2007 00-45-52

I get asked this question a lot.

Unfortunately the short answer is: No – A standard grid connect solar system will not protect you from blackouts.

Kind of counter intuitive isn’t it? You go to the trouble and expense of your own little solar power station, and then you have no power if the electricity grid goes down. [Read more…]

Solar Power Forecast for 2012: More stability, better forecasts, fewer conspiracies?

solar to grow in 2012?

This year should be the year that renewables start to take off in Australia:

  • We will have a carbon tax in place that will support renewable energy and overseas money is starting to flow in.
  • Large scale solar is finding funding, following the trend from overseas.
  • Chinese production of solar panels is bringing the cost of solar energy rapidly down towards that of fossil fuels.

But there is one factor that governments, both federal and state, need to provide: stability.

The solar industry needs to sense that financial support given in one year won’t be withdrawn the next when the going gets tough or when a newly-elected government reverses the previous government’s solar policy just because they can.

Certainly in the case of solar energy the governments’ efforts to forecast costs got an “F” grade this year. In a New Year’s resolution that we think makes complete sense, the Australian Solar Energy Society (AuSES) has promised to carefully watch over the government’s solar forecasting in 2012 on behalf of the nation’s solar industry. Reading between the lines it seems AuSES is none too pleased with the end-of-year report card for government forecasting agencies.

“As a national voice for Australia’s solar industry, the Australian Solar Energy Society has made a New Year’s resolution: to work more closely with Government agencies to ensure there’s no repeat of the 2011 solar forecast mistakes,” the society said in a recent release.

This brings an image of government forecasters sitting in class rooms watched over by AuSES teachers. The solar forecasters, gazing out into the playground where their fellow  number crunchers are all playing, before looking down and writing: “I must not bugger up the solar forecasts again” 100 times.

Am I being too harsh here? After all a forecast is just as it states: a forecast. But surely it should have some relation to the outcomes?

The AuSES release points to four key areas where forecasts had to be speedily revised to bring them to within a bull’s roar of real outcomes.

1. The Productivity Commission’s overstating of the cost of solar subsidies per tonne of CO2, forcing it to revise down the cost of solar subsidies from $431-$1041 to $177-$497.

2. The Energy White Paper, released by the federal government, which overstated solar’s cost by a factor of three.

3. The Treasury Department’s estimate that the country would have around 9 gigawatts of solar by 2050. However 1.2 gigawatts has already been installed, with yearly installations increasing ten fold since 2009.

4. The NSW Government, led by Barry “The Terminator” O’Farrell, forced to revise the cost of the state’s solar bonus scheme down by nearly a quarter.

Hardly inspiring is it? No wonder AuSES chief executive John Grimes described 2011 as “a horrible year for government solar forecasting”. And why are the forecasts always so against the interests of the solar industry? Is the reason for the solar forecasting simply the innocent result of a culture of excessive drinking and partying in our state and federal capitals? Or are there other motives at work?

There you go folks, a nice little conspiracy theory to kick off the year. Wishing you all a safe, happy and productive New Year.

Silex Solar Closes its Doors and Blames Usual Suspects

Somewhere in between the strenuous media frenzies that accorded the visit of The Windsors and later the Obamas, the Australian media managed to find time to report on the final demise of the (previously) only manufacturer of solar cells in this country.

The Homebush, NSW-based SilexSolar company — previously associated with BP — finally closed its doors this week with the loss of 45 jobs. The news was another body blow to the NSW solar industry which has seen a number of setbacks under the O’Farrell Government.

Sad Silex Solar

For full details of the collapse, see this Sydney Morning Herald article.

Silex chief executive Michael Goldsworthy blamed the usual suspects for the company’s demise doors including an oblique reference to ”… we think we’re seeing dumping” (read China solar panel production here). An interestingly-titled “Interim Operational Update” issued by Silex on the 15th November didn’t hold back.

Will Port Augusta Point the Way to the Future of Solar Power?

This week’s column will take you into the realms of fantasy (if you’re a talk radio shock jock or anti-renewable pollie). Yes folks we’re treading into the dangerous territory of the concept of solar energy as baseload electricity.

For years one of the constant carping criticisms aimed at renewable energy in this country has been that it won’t provide baseload power resource in the same way as good ole fossil fuel-derived power. The argument goes that when the sun stops shining, or the wind stops blowing, renewable energy cannot deliver.

While the criticism may well have been a smokescreen thrown up to keep high polluting coal plants in operation, the point is valid: how can you rely on a source of energy if the power it creates cannot be stored?

Large-Scale vs Domestic: Where Should the Dosh Go?

The federal government has been accused of dragging its feet on solar energy (and renewable energy in general) in comparison to more dynamic regions such as North Asia, Europe and the United States. Innovative and well-targeted government support in these countries has seen the increased takeup of solar power and a boom in their respective solar industries.

However, one feels our overworked and underpaid elected reps (bless ‘em) would be up in arms at the suggestion of neglect of solar initiatives and would point to the key area of the federal Solar Flagships program as proof of this. [Read more…]

Will the Carbon Tax Boost Large-Scale Solar Projects?

The debate over whether or not a carbon tax will be effective has split families, pitched neighbour against neighbour, divided loyalties and torn our nation asunder.

Well not exactly, but a real blockbusting start to this week’s column you have to admit!

On a serious note, the question many SolarQuotes readers would like answered about the carbon tax goes something like the following. Will the carbon tax (assuming the legislation is passed) bring any benefit to the solar power industry in Australia? [Read more…]

Is WA’s Support of Solar Utilities at the Expense of Domestic Projects?

When we think of Western Australia we generally consider mining booms, expanded gas projects, black swans and the West Coast Eagles football team (and Dennis Lillee and Rod Marsh for those of us with age on our side).

But as an Australian leader in solar technology? After a recent government decision to close down its solar feed in tariff scheme because of its (wait for it) popularity, the expected answer would generally be no. However recent developments in the West have shown government-owned corporations partnering up with the private sector to lead the state down the path of potentially being one of the country’s leading exponents of renewable energy.

Subsidies in Frame as Silex Ends Local Solar Cell Manufacture

By Rich Bowden

Solar industry news in NSW this week has been dominated by the announcement by Silex Solar, the last company to manufacture solar cells in this country, that it will discontinue the production of locally made cells. (Note the solar cells are the black, round, saucer sized, plates of silicon, which make up solar panels).

In an announcement earlier this week, the company said while it would continue to manufacture solar panels at its Homebush, Sydney plant, it would do so with solar cells from an as yet unnamed overseas country (read China). [Read more…]
