How I got a $33 power bill with solar – even with a crappy 8c buy back rate

February 5, 2015 2019-09-16T11:35:08 by 173 Comments

Update: This post was written in 2015. It is still worth a read to understand how solar affects your bill – but if you want to browse all my recent bills you can do so here.

I got my quarterly electricity bill last week. It was $33. I was so happy that I tweeted AGL.

AGL’s reply is priceless:

I’m guessing AGL don’t get a lot of compliments on Twitter! I also posted a scan of my bill on SolarQuotes’ Facebook page:

If you want a 5kW solar system in QLD – consider getting it before March 1 2015!

Rules for installing solar in QLD change on March 1

****UPDATE****

On 12th Feb 2015 Ergon and Energex announced that they are extending this deadline from 1 March out to 30 September 2015.

*****************

The Queensland electricity networks (hello Ergon and Energex!) are a fussy bunch. At the time of writing (Jan 2015) if you want to install a standard grid connect solar system bigger than 5kW, you need to jump through all sorts of technical hoops. And then the networks may also insist that you install a box of electronics that stops any of your excess energy being exported. That’s right you have to waste any excess clean energy instead of letting your neighbours use it! [Read more…]

3 Phase Solar Wars : The Menace of Phantom Imports.

May the (electromotive) force be with you!

 

I’m thinking of writing a screenplay. The movie’s name is “3-Phase Solar Wars : The Phantom Imports”. Here’s the opening scene:

“Quite soon in the future, in a suburb not very far away….

 

It is a period of civil war. Solar owners, striking from over a million rooftops, have won their first victory against the evil Electricity Empire.

 

During the battle, these plucky rebel homeowners managed to get their electricity bills down so low that they are on the cusp of destroying an entire electricity retail industry.

 

But now the Empire’s sinister agents have a plan:

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

December 29, 2014 2017-04-19T14:50:50 by 10 Comments
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.

Solarmax Inverter Bankruptcy: What it means for Solarmax owners.

December 17, 2014 2017-04-20T10:33:07 by 18 Comments

Solarmax have gone bust.

Bad news for fans of Solarmax inverters as its parent company, Sputnik Engineering, has just filed for insolvency.

Solarmax are a 20 year old Swiss inverter manufacturer who made fantastic quality inverters at a great price. It seems, with hindsight, that the price was a little too great!

If you were considering buying a Solarmax, then you should probably change brands so that your warranty is with a solvent manufacturer. Go for a big brand like SMA, Fronius, Sungrow, ABB, Zeversolar, Delta, Enphase or Solarbridge (feel free to leave any big brands I’ve missed out in the comments!)

If you already have a Solarmax on your home, then don’t panic! [Read more…]

Does Sunpower + Solarbridge Microinverters = World’s Best Performing Solar System?

A lot of Aussie solar installers really dislike microinverters. In fact many refuse to install them.

The main reason is a fear of inverter failure. The reasoning goes something like this: [Read more…]

Genius Or Bonkers? US solar company glueing solar to roofs to reduce installation costs.

November 28, 2014 2024-07-03T11:45:32 by 14 Comments

Innovation in solar never ceases to amaze me. But I can’t decide if this particular innovation is genius or totally nuts.

US solar panel manufacturer Lumeta Solar have announced a new 175W solar panel design that is super thin, with no frame, a junction box on top instead of underneath, and get this: double sided sticky tape on the back.  The idea is that you simply peel the backing off the tape and stick the panel to the roof.

Coal vs Solar – Which is more space efficient?

November 19, 2014 2024-08-18T20:37:00 by 6 Comments

solar and a coal fired power station

This is a guest post by Greg Bell – which was conceived in the comments section of another post on this blog.

Take it away Greg:

——-

Some things we can say we know for sure about photovoltaics – the fuel is free, it’s quiet, and there are no moving parts. But other benefits are more controversial. Recently a claim was made to me that solar PV is actually more area efficient – that is, it generates more energy per hectare – than coal.

Specifically, the claim was

“The 1,600 megawatt brown coal Hazelwood Power Station and associated mine in Victoria covers 3,554 hectares. In a sunny location in Australia 20% efficient solar panels covering that area would produce more kilowatt-hours than Hazelwood’s average output.”

Let’s see if that’s true. [Read more…]

Are micro inverters & battery backup compatible?

3 microinverters and 2 batteries

Can you combine micro inverters with batteries? Yes you can!

Can you use a micro inverter off grid? Or even for grid connect with batteries?

With the growth in the use of micro inverters, I’m starting to get more and more emails asking: can micro inverters be used in off grid (or hybrid) solar power systems? [Read more…]
