If, like me, you get turned on by Solar Inverters, then here are three companies doing very cool stuff that I think you should look out for in 2012:
How Much Does Off Grid Solar Cost?
I had a phone call from a mate today asking for advice on buying an off grid solar system for his new house in suburban Melbourne. He was pissed off about paying the daily grid connection charge when his solar system was easily going to produce more power than he used. A typical grid connection charge is about $1 per day.
So what is the extra cost of getting completely off the grid with your solar system in the city compared to a standard grid connect solar system?
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…
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?
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…]
13 Solar Questions You Must Ask To Weed Out The Shonks
One of the questions that lands in my inbox almost every day is this:
“Hey Finn – I’ve been made a fantastic offer on a shiny new solar power system for my home. It is heaps cheaper than every one else on the market. Is it too good to be true or a genuine bargain???”
Here are 13 Solar Questions to quickly ask either yourself or the solar sales dude that will help you decide. [Read more…]
The Problems With Thin Film Solar Panels
If you are looking to buy a solar power system and have done any kind of research on the web, then you have probably come across lots of people arguing over the pros and cons of Thin Film Solar Panels compared to the more common monocrystalline or polycrystalline solar panels. In a nutshell, there are 3 major types of solar panel technology on the market:
- MonoCrystalline,
- PolyCrystalline
- Thin-Film
It seems a lot of people are firmly in either the “Crystalline” or “Thin-Film” camp. And when discussing which panel is best, they can easily lose their objectivity with arguments along the lines of “Thin Film is the only way to go” or “Mono Crystalline and Poly Crystalline are junk!”.
Don’t Make these 10 Mistakes When Buying a Solar Power System
1. Buying the cheapest – because it is the cheapest.
If a solar system seems too cheap to be true, then it is probably is!
Here are 4 ways they get the price so low:
a) The solar company is buying absolute junk panels and inverters on the spot market in China

How to Spot a Solar Cowboy
By Rich Bowden
OK so you’re almost ready to make that big decision to install solar panels to save on your sky rocketing power bills while doing your bit for the environment. But, mindful of recent poorly-regulated installation disasters (who remembers the Pink Batts saga?) you’re leery of the same type of dodgy operators who may operate on the fringes of the solar industry. Obviously safety and correct installation of panels are two of your main goals and you want to avoid the “solar cowboys” from getting anywhere near your roof.
Easier said than done (I hear you cry). What does a “solar cowboy” look like and how do I find quality solar installers?
Well one way is to seek the advice of an expert and I’ve managed to nail down SolarQuotes.com.au founder Finn Peacock to answer some common questions:
Can anyone install solar panels?
Finn Peacock: In theory yes – if you can climb on a roof, drill some holes, assemble the racking, screw the panels on to the racking and connect the panels to the racking, you can theoretically install the actual panels yourself.
But – and it’s a big but, working on a roof is really quite dangerous, and if you haven’t got a lot of experience drilling holes and/or lifting tiles etc, you may regret it when the rains come. Also when the solar panels are being connected up electrically (before they are even connected to the grid) you can have a voltage build up of several hundred volts and that can quite easily prove fatal.
Remember – solar panels will create a voltage even when they are disconnected from anything else – so you really do have to know what you are doing. Also there are certain ways you need to earth and protect the solar panels, which if done incorrectly will either leave you with an under performing or dangerous system, or both. And when it comes to installing the inverter, you start dealing with mains electricity and it is technically illegal in Australia for anyone other than a qualified electrician to do that. So, yes, if you live for danger and don’t mind breaking the law you could theoretically save a thousand dollars or so and go the DIY route. I obviously cannot recommend this though!
How do I know if a tradesperson is qualified to install solar panels?
FP: Ask them for their CEC accreditation number then go to solaraccreditation.com.au and look them up. Check that they are qualified to install systems. Some CEC accredited people are only qualified to design systems.
How do I find a reputable solar installer in my area?
FP: If you’ve got a friend that has got a system and they had a good experience, then find out who did it and get them to quote.
I’d also recommend getting at least 3 quotes to compare that one with, which is why I started SolarQuotes.com.au of course! Just go into the site, add your postcode, fill in the required details and up to three quotes from installers in your area will be made available.
What guarantees do I have that the work will be up to an acceptable standard?
FP: The install has to be signed off by a CEC accredited installer, so I’d hang around for the inspection and make sure that he actually has a good look over the system. Also be aware that technically the guy installing the system doesn’t have to be accredited as long as he is “supervised” by a CEC accredited installer. So make sure that the supervisor really does supervise the install (or ideally actually will do the install). There are some known cases where cowboys will leave the apprentices to do the install and just get a CEC accredited installer to sign the paperwork at the end with a very superficial inspection at the end – if at all.
Is there an overseeing industry regulatory body?
FP: There is the CleanEnergyCouncil, although some other industry bodies are trying to start even more stringent certification schemes, with AUSES and SEIA leading the charge.
Do you provide a rating system for solar installers?
FP: I think the best way to judge any company is to read uncensored reviews by past customers, so I publish thousands of these for all solar companies (not just ones in the SolarQuotes network).
I’d like more information about the types of solar panels available. Where can I find this?
FP: I’ve brain dumped all my knowledge here and I’ve got a really cool solar panel performance comparison tool coming in a few weeks which will be able to be linked to from that page.
I keep hearing that I may be eligible for state and federal government solar rebate schemes. Where can I find easy-to-understand information on this?
FP: I’ve explained the ins and outs of solar credits here and solar feed in tariffs here on the website.
Thanks to Finn for taking the time to share this information with us. But have we missed any important questions that you’d like to see answered? Please let us know and we’ll seek to answer them for you.

Solar Subsidies : Let’s get the facts straight
Despite running a popular Solar Power website, whose revenue is seriously helped by generous Federal and State solar subsidies, it may surprise you to learn that I’m not a huge fan of government subsidy in any shape or form. Mainly because I have worked for the government and seen how inefficient they really are. Trust me it is frightening.
I would be happy for the Feds to completely scrap their solar subsidy, called Solar Credits, and let the economics of small scale solar stand on its own merit through innovative finance schemes designed by innovative Solar Installers. [Read more…]
