Misleading Statements On Sunrise Hurt Solar Industry

September 23, 2016 2017-04-18T15:36:26 by 24 Comments
sunrise

The scene in the Brakels’ household last Sunday morning.

On Sunday morning the program Sunrise had a segment on solar power and battery storage. While I am glad whenever popular TV takes the opportunity to educate people on these topics, that wasn’t what happened here. It was the opposite of education, as anyone watching it could easily come away believing the following three things:

1. Battery storage pays for itself.
2. Battery storage cuts CO2 emissions.
3. Rooftop solar needs batteries to be worthwhile.

None of these things are true.

Battery storage does not pay for itself when used on-grid and it may be years before it does.

Home batteries do not cut emissions, they increase them. In the future they may allow us to decrease greenhouse gas emissions, but that point is still years away.

Rooftop solar by itself is cost effective. It is adding batteries that can make it uneconomical.  The mistaken belief that rooftop solar needs batteries to be effective is causing harm to both the solar industry and the environment, as people are delaying installing rooftop solar until batteries become affordable.

Cheapest Electricity Plans For Solar Owners Revealed

September 8, 2016 2024-01-25T16:57:19 by 31 Comments
ronald's head exploding

This is how I felt after spending 2 days trying to work out the best electricity plans for solar owners.

I’ve said it before and I’ll say it again, electricity bills are confusing.

If you are one of those rare people who don’t find electricity bills confusing, then I have two things to say to you. Firstly, “Good for you”.

Secondly, “When are you returning to your home planet?” because I find it hard to believe you are human.

Because they are so confusing, it is very difficult to know which retailer offers the best plan for your household. Especially for people with rooftop solar, as they have the additional complication of accounting for feed-in tariffs. [Read more…]

Does Battery Storage Help Or Hurt The Environment?

an eco-warrior dreaming about a powerwall

If you want to save the environment and have limited funds, then buying batteries should not be a priority.

Millions of Australians have installed rooftop solar to help the environment and save money.

Many are hoping home battery storage will soon let them do the same.

The cost of home energy storage is falling rapidly and it may not be long before it pays for itself.  But at its current price it will not save money, even under favourable circumstances, when used on-grid.  Despite this, there have been hundreds, or possibly thousands, of people who have installed home battery systems because they want to help the environment.

Have these people  made a horrible mistake? [Read more…]

Victoria’s Residential Demand Tariffs: Designed To Cripple Rooftop Solar?

August 19, 2016 2016-08-19T09:02:48 by 11 Comments
an evil genius pasting demand tariffs to a solar panel

The Victorian demand tariff appears to be a cunning plan to slow the spread of solar.

Residential demand tariffs are now available in Australia, and I recommend you watch out for them. If you are a modest user of grid electricity, as many solar owners are, they have the ability to blow your electricity bill through the ceiling. [Read more…]

How Residential Demand Tariffs Could Add $1000’s To Your Bill

August 16, 2016 2016-08-19T08:13:47 by 17 Comments

demand tariff

Electricity companies around Australia are starting to roll out a new way to charge you for electricity. It is called a residential demand tariff.

Unsurprisingly this new tariff can result in higher bills for you, and higher profits for them.

This post is important. It will explain to you what a demand tariff is, how it works, and why many households should avoid it at all costs.

The electricity companies want to make demand tariffs the norm, so you must be armed with the knowledge to spot one when you see one, and understand the implications of signing up for one. [Read more…]

Why Oversizing Solar Panel Arrays Is A Smart Move

August 9, 2016 2024-04-08T10:18:05 by 87 Comments
house with lots of solar panels

Did you know you can add panels up to 133% of your inverter capacity? Read on to discover why oversizing solar is a smart move (as long as your roof is big enough – unlike this guy’s).

Installing rooftop solar systems with a total panel capacity greater than the inverter capacity is usually a very good idea.  It will certainly save you money, but it can also help get around the restrictions many Australians face on the size of inverter they can connect to the grid. [Read more…]

Will LGCs Pay More Than STCs on a 10-100kW solar system?

July 26, 2016 2018-02-23T18:21:05 by Leave a Comment
solar panels

There are 2 subsidies for solar under 100kW: STCs (AKA the ‘solar rebate’) and the lesser known LGCs. Which one will give you the better return?

Update 23rd Feb 2018: Solar installations of 100 kilowatts or less now only receive STCs.  However, applications made before March 31st 2018 for systems of 10 to 100 kilowatts may be accepted under the old rules and permitted to receive LGCs.

Many people are aware the Renewable Energy Target, or RET, lowers the cost of rooftop solar.  This is often called the solar rebate, even though that term is not entirely accurate.

But what few people know is, provided their system is large enough, they have a choice in the type of assistance they receive.  A household with a 10 kilowatt rooftop solar system can either accept Small-scale Technology Certificates (STCs) or Large-scale Generation Certificates (LGCs).

Almost all solar systems 100kW and smaller, currently being installed use STCs because they are all deemed immediately after the installation whereas LGCs are deemed annually over 15 years.

At the time of writing (July 2016) STCs are $38 each whereas LGCs are at a sky high $82. This has made some savvy solar installers wonder if using LGCs instead of STCs might create a better return for patient solar owners. [Read more…]

Standard Tariffs Vs Time Of Use Pricing. Which Goes Best With Solar?

July 8, 2016 2021-08-09T15:46:56 by 25 Comments
time of use meter

What will give you the lowest bill, a standard or time of use tariff? What if you add solar? What about batteries?

Australians pay for grid electricity in two ways.  The most common way is a standard tariff. But you can also choose a time-of-use tariff.

What is a standard tariff?

This is where you pay a fixed rate for each kilowatt-hour used, plus a hefty supply charge.  Australians have been paying for electricity this way since the the electricity meter, invented in 1888, was developed into the ‘spinning dial’ type in 1914. So Australians have been using standard tariffs for over  a century. [Read more…]

Keith De Lacy Is Not Right About Solar And Wind Power – Not Here, Not Anywhere

June 27, 2016 2017-04-18T18:01:05 by 26 Comments
article

A response to Keith De Lacey’s article in the Australian last week.

The Australian recently published an opinion piece by the Director of an oil shale company and former Chairman of Macarthur Coal, entitled, “Solar And Wind Power Simply Don’t Work – Not Here, Not Anywhere“.

This was surprising because the solar panels above my head are producing electricity right now.  And since I know exactly how much I paid for them I know they are definitely economically worthwhile. Also, because I know exactly how much the STCs I received as part of Australia’s Renewable Energy Target were worth I know the rooftop solar system would still pay for itself even without subsidy.
