Huge Jump in Queensland Commercial Solar Installations

office in QLD with solar

Offices and Factories in QLD are installing solar at an increasing rate.

We’ve documented before the lack of love of the Newman government towards solar energy in Queensland. In the midst of a state election where the shrill rhetoric is matched only by the embarrassing speed of the election call, the level of antipathy has risen as the LNP seek to demolish the arguments of the pro-renewables lobby.

However, despite the LNP’s efforts, it seems an important chunk of their traditional electorate aren’t listening. [Read more…]

SA Power Networks’ Shonky Voltages Causing Headaches For Adelaide Solar Owners

Most solar inverters will shut down at 257V.

Most solar inverters will shut down at 257V.

I’m getting reports that lots of solar owners in Adelaide have seen their inverters shut down over Christmas.

No, the inverters are not taking a break to eat mince pies and open their presents – they are shutting down because the grid voltage seems to be regularly going higher than 257V. Many inverters are designed to shut down when the grid gets this high, in order to protect the inverter electronics.

According to the Australian Standard (AS 60038-2012), the grid should be kept at 230V -6% / + 10%. So the highest it should get is 253V. [Read more…]

Why connecting your solar system to the grid is harder in NSW

grid connect solar

What are the rules for connecting to the grid in NSW?

Australians love their rooftop solar and believe it or not, despite our relatively small population we have collectively installed more household solar systems than almost any other country in the world.

For consumers, it’s a no brainer but the electricity companies seem to be making things more difficult as time goes by. Is this justified and are their technical issues we need to understand as solar owners, or are they just profiteering?

The grid is a complex beast and the electricity industry is even more complicated, so the answer is ‘a bit of both’. In fairness to the utilities, and because I’ve had a heap of emails from frustrated NSW folks, I thought I would highlight the New South Wales Service Rules as one example of how technical issues need to be considered.

ARENA: the government renewable energy agency that refuses to go away

ARENA - the gift that keeps on giving.

ARENA – the gift that keeps on giving.

Remember ARENA? The plucky Australian Renewable Energy Agency that has helped many renewable energy ventures and research with seed funding and other support? The ongoing benefits of ARENA include not only financial support but also because their involvement has helped pave the way for research and development in partnership with the private sector.

Wait. Ongoing? Didn’t ARENA get axed by the feds in their anti-renewables Budget cuts zeal a while back?

Well no. At least not yet. For ARENA, to quote an oft-used phrase, is the gift that keeps on giving.

Though the agency has, as you’ve probably heard, been axed by the federal government as part of its thinly-disguised ideological campaign against renewables, it still refuses to roll over and die. [Read more…]

Solar will be the world’s most popular power source by 2050

big red hand pointing down

Down, down, solar panel prices are going down!

When someone of the stature of Martin Green says the cost of solar PV technology will halve again by the next decade, you sit up and take notice. Even more so when he says solar will be the world’s most popular energy source by 2050.

For the University of New South Wales’ Prof. Martin Green is considered one of the world’s leading PV researchers. His department’s technological breakthroughs in silicon cell efficiency have not only given us the solar panels we know today but also put Australian PV research at the centre of world PV technology.

“The costs of solar will halve again by 2025 is my prediction,” he told a conference in Sydney on Wednesday. “We are at 60 cents per watt manufacturing now but we will get down to 30 cents per watt some time before 2025.”

Focus on solar microgrids as fossil fuel wavers

microgrid with solar and PV

Taking whole streets (or villages) off the grid is likely to become more common.

What role will community-based solar microgrids play as Aussies look for environmental and affordable energy alternatives?

First, I should explain what a microgrid actually is. It is simply a cluster of buildings, all connected together electrically, but not connected to the wider electric grid. An example would be taking your whole street off the grid instead of simply your own home. If you do this, you can share solar generation and battery storage among other things. As feed in tariffs get lower, this becomes more attractive. Wouldn’t you rather your sell excess solar energy to your neighbour for a fair price than be forced to sell it to someone like Energex for a miserly 6c per kWh?

According to analysts Frost and Sullivan’s report “Analysis of the Asia-Pacific Microgrid Market” the microgrid electrification (including solar programs) is expected to reach a sales figure of $813 million by 2020, growing at an expected astonishing rise of 38.3 percent over that of 2013. Countries surveyed by Frost and Sullivan include Japan, Indonesia, South Korea, Malaysia, the Philippines and (yes!) Australia. [Read more…]

The Truth About Your Roof And Solar Power: 3 Questions You Must Ask.

roof with panels

Is your roof good for solar?

Imagine you walk in a shoe store and the shop assistant immediately starts measuring your head with a tape measure. You’d think she was mad, wouldn’t you? And you’d be right, of course. Sometimes the basics are just self-evident.

If you need shoes, all the information you need is right there at the bottom of your legs. Same with solar power.  No reason to start anywhere but right up there on your roof.

And there are 3 questions about your roof that you have to answer right away before we move on to anything more advanced. And you’ll soon see why…

How Do You Know If Your Roof Is Good For Solar Power?

Back to the absolute solar basics today on the SQ blog!

In this video I describe the 3 things you need to understand about your roof before buying a solar power system.

And here’s the transcript if my pink shirt gets too much for you: [Read more…]

How Much Will You Get Paid For Your Solar Electricity?

Hint: It’s a bit more complicated than you might think!

By my reckoning 25% of people buying solar power systems want to save the planet as a priority. The other 75% want to save their bottom line and saving the planet is a nice side-effect.

I get a lot of emails saying: “Help! My bills are [insert large number here] dolars a quarter – what size solar system do I need?”

The answer to this question is quite longwinded – but if you want to understand whether a solar system is worthwhile for you financially – you need to understand this stuff! So I made a video to help explain. If you are considering buying a solar system I strongly recommend watching this:

[Note: Since I made this video the Victorian and QLD Feed In tariffs are no longer more generous than the rest of the country – they are both 8c per kWh at time of writing!]
