What is a PERC Solar Panel?

34 years after it was invented ‘PERC’ is now a big deal in solar panel technology. But what the hell is it?

Update 16th April 2019:  Many PERC panels have suffered from LeTID deterioration problems since this article was written.  This article here goes into the problem and this article on the MC Electrical blog covers it in detail and gives information on which PERC panels are resistant to LeTID.

Solar panel manufacturers crave efficiency.  I’m not talking about the labour efficiencies they receive from building new production lines that are robot-heavy and people-light, although they like those too. [Read more…]

Can An Installer Change The Quoted Price Of My Solar System?

stc price

The STC price has plummeted and pushed the price of solar up. What should you do if you’ve already accepted a quote and the installer wants to increase the price?

I’m going to ask you to imagine preparing to buy a rooftop solar system.  I want you to see yourself working hard, saving your money, doing your research, and getting yourself some quotes.  After careful consideration, you decide upon an installer, sign the contract, and transfer a 10% deposit to them.  At that point you would be looking forward to saving money on your electricity bills and doing your bit to help the environment.

Now imagine how you’d feel if, before the day of the installation, the installer contacts you and says the price has gone up and you now have to pay $1,000 extra.

I imagine you wouldn’t be very happy about it. [Read more…]

SolarEdge HD Wave Review:  The World’s Smallest And Most Efficient String Inverter

July 20, 2017 2024-01-25T13:20:13 by 45 Comments

Today Ronald examines the SolarEdge HD Wave inverter. It’s small. But not that small.

It’s An Itsy Bitsy, Teeny Weeny, SolarEdge, HD Wave String Inverter…

SolarEdge, an Israeli company, has produced the HD Wave — the world’s smallest string inverter.  By size, this little cracker takes more DC than any inverter out there.  Not only that, but it grabs DC, uses its funky HD wave technology on it, and spurts out the AC our homes use with greater efficiency than any thing else on the market.  And it’s now available in Australia, starting from a couple of weeks ago.

Solar Panel Clamping Zones: Are Your Panels Mounted Correctly?

That clamp is not in the zone! After reading this post you will know what that means. (Photo credit: Matt Hines – definitely not one of his installs)

There is one main way solar panels are attached to roofs in Australia and I’m hoping you won’t be surprised to learn it’s not glue.  If you’ve got panels, they are almost certainly fastened to your roof with clamps and held tight in the loving embrace of metal brackets. [Read more…]

Chinese Company ‘Tesla New Energy’ Steals Tesla’s Name And Logo

The ‘Tesla New Energy’ website yesterday.

Many people are aware Tesla is planning to produce solar tiles, but not so many know the company is also has plans to sell conventional solar panels.  According to one report, Tesla is going to follow the novel approach of producing them inside a buffalo in New York.  Production is scheduled to begin within two months and the panels will only be available from Tesla.

The panels are not featured on Tesla’s Australian site and I currently have no information on when or if they will be available here.  But if you do enough searching on the internet or, more likely, receive some spam from them as I did, you may think you can order some of these panels from the Tesla New Energy factory in China.

Solar For Renters? Landlords & Tenants Share The Benefits with ‘Matter’

July 11, 2017 2017-10-19T10:25:18 by 21 Comments
rental property without solar

Have you ever noticed that rental properties almost never have solar?

Australia has the lowest cost rooftop solar in the world, plenty of sunshine, and because we are heading towards having the most expensive pre-tax grid electricity in the world, solar is a must have for almost anyone who owns a roof.

But over the past 11 years Australian home ownership has fallen from 70% to around 66% and since it costs over a million bucks to buy a butterbox in Sydney, this figure isn’t likely to improve any time soon.  This means one-third of the Australian population is locked out of owning rooftop solar.

P-Type And N-Type Solar Cells’ Excellent Electron Adventure

p-type and n-type

Do you know the difference between a P-Type and N-Type solar cell, duuuuuude?

When it comes to material for making solar cells, silicon is the most bodacious of all the elements.  Its market share is an excellent circa 97%1.  If you want solar PV, there is next to no choice other than silicon.  However, there is more than one type of silicon cell, which is fortunate for people who enjoy faffing about when deciding what to buy.
