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.

China Plan To Whip Australia’s Ass in Domestic Solar Investment

Whilst many Australian state governments dither over the solar feed-in-tariff (FIT) issue, China has come charging out of the changing sheds recently with a brand new, highly-polished, national feed-in-tariff system.

They are kicking the world’s ass when it comes to high value manufacturing (where was your iPad made?) and now it looks like they are serious about installing solar power domestically. [Read more…]

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.

How to build a giant Solar Powered Oven

Does your house feell like a forced fan convection oven in summer?

Here’s how to build a highly efficient, giant solar powered oven.

Eight steps to making sure your oven gets as hot as possible in summer: powered by nothing other than the sun!

1. Erect a wooden frame about the size of an average house.

2. Build bricks around the outside of the frame. Bricks have a good thermal mass, which means that as the sun shines on them in the day, the bricks will store the heat and radiate it back into the oven long after the sun has gone down.

3. Fix a very low thermal mass material (like plasterboard) to the inside of the timber frame so that if any cool air gets in the oven (heaven forbid), the coolness won’t be stored in the inner walls.

4. Put lots of glass in the walls (avoid double glazing at all costs), especially the north facing one. Make sure these windows have minimal awnings.

5. Put black colorbond (ideally) or dark tiles on the top of the timber frame to maximize the heat absorbed by the ‘roof’ of the oven.

6. Add a fan that blows air down from the top of the oven. This way, as the hot air inside the oven rises, you can blow it back down to floor level to makes sure that anything on ground level gets suitably cooked through. To keep things simple, we’ll refer to this ventilation system as the ‘Ducted Air System’

7. If you are worried about cool air getting into the Ducted Air System, then simply add an insulated ceiling to create a roof space.  Ensure all the ducted air system’s pipes are kept inside this ferociously hot roofspace.  This will  minimize the chance of any air in the pipes actually getting cold.

8. If the meat in the oven needs a little more grilling, then add dozens of high powered halogen heaters liberally recessed into the ceiling. As well as producing enormous amounts of heat these little halogen bulbs will produce a small amount of light as an added bonus.

If your house was built like this and resembles an oven in summer,  the two most cost effective things you can probably do are:

a)   Fit mains or solar powered fans into the roof to remove the hot air from the roofspace. These will remove 7-10 times as much air as a passive ‘whirlybird’.

b)   Fit external awnings on all N, E and W facing windows.

If you do those and your cooling bills don’t halve, I’ll eat my cancer-council approved wide brimmed hat.

Huge Subsidies (and waiting lists) for Solar Hot Water in QLD

The Queensland Solar Hot Water program is delivering and installing $500 systems for eligible Queenslanders and $100 for pensioners. But as you might expect, there is the mother of all waiting lists.

To date more than 850 customers have been allocated to suppliers to conduct inspections and install new systems.

By the end of this week over 110 systems will have been installed in Brisbane and a further 200 have been contacted to arrange site inspections.

More than 43,000 Queenslanders have registered their interest to participate in this program with more than 10,000 completed applications received so far.”
