The United States has announced import tariffs of 30% will apply to all imported solar panels but a yearly quota of 2.5 gigawatts of imported solar cells, or enough to make around 9 million panels, is allowed. Just how much the United State’s Figurehead in Chief, Donald Trump, had to do with this decision I don’t know, but when you vote in someone who is only good for being blamed you may as well get as much mileage out of that as possible. So they will be forevermore known as the Trump solar tariffs and that’s definitely what they’re being called in the news. [Read more…]
Black Solar Panels: Is Lower Efficiency Worth The Sexy?

Black Solar Panels Are Hot! This Reduces Efficiency.
I want you to think about someone you know who has rooftop solar. It doesn’t matter who. It could be a friend, a relative, or that handsome bearded man you’ve been stalking for months — it doesn’t matter. I want you to think about where they live. Picture their home in your mind’s eye and then answer these two questions: [Read more…]
Want Hundreds Of Dollars Worth Of Cool Cash? Buy An Energy Efficient Fridge

Ronald’s fridge yesterday.
Disaster has struck the Brakels household! And I’m not talking about a minor disaster like a son or daughter breaking a leg.
Australian Standards Must Be Free For The Benefit Of Education, Business And The World.

Australian Standards must break free. Charging hundreds of dollars per standard is nuttier than wearing high heels while vacuuming.
People say I have no standards, but that’s only true in a legal sense.  You see, I do have access to Australian Standards that have been purchased by my employer, SolarQuotes. While these particular standards have a heavy focus on how not to kill people when mucking around with electricity, there lots of other ones covering almost everything you can think of – and quite a few things you’d be very unlikely to think of.  [Read more…]
Rooftop Solar And Exclusion Zones: Where Solar Panels Dare Not Go

How close to the edge of the roof should your solar panels go?
In the past I’ve written about solar panel clamping zones which determine where, on a solar panel’s edge, you can place the clamps that attach the modules to their mounting rails. What I didn’t do was go into just where on a roof solar panels can and can’t be installed. [Read more…]
Bifacial Solar Panels May — Straight Up — Dominate Australian Solar Farms

Are vertical solar panels the best orientation for new Australian solar farms?
Last week I wrote about double glass bifacial panels that are able to use light coming from the front and behind, while on Christmas Eve I mentioned large scale solar farms are taking off in Australia. Because it’s the season for togetherness, I thought maybe we could put these two things together and make a bifacial solar farm.
Merry Christmas And A Happy Old Year
Well, another year is almost gone and so to everyone I say, Merry Christmas and a Happy Old Year! [Read more…]
Double Glass, Glass On Glass, and Bifacial Panels — What The Hell Are They?
Glass is a vital part of almost every solar panel installed on Australian roofs. The sheets of glass used to protect solar cells are long lasting, non-reactive, very tough, and — above all else — it’s transparent. As a result glass functions far better than wood, cheese, iron, or mucus. [Read more…]
The Solar Panel Warranty Paradox

Presenting “Ronald’s Solar Panel Warranty Paradoxâ„¢ “. Or what happens when you spend too much time thinking about solar panels and not enough time playing Dungeons & Dragons.
Why Solar Panel Warranties Are Less Important Than You May Think
I’ve written one or two blog articles over the years and if you’ve happen to have seen them, you may have noticed I have a thing about solar panel warranties. Specifically, I like ’em long. The longer the better. It’s a little peccadillo of mine. Because of my predilection for impressive warranties you could, quite understandably, reach the erroneous conclusion that I think a good solar panel warranty is a valuable thing for a household to have. But this is not the case. I think for all practical purposes most solar panel warranties will be almost worthless. [Read more…]
Should you scrap your 1.5kW solar and replace it with a bigger system?

Should you bite the bullet and scrap your 1.5kW solar system so you can fit a bigger system on your roof?
Five to eight years ago, just as the Australian solar industry was getting underway, many people locked in high feed in tariffs for their new, cutting-edge solar power systems. For example, many people in Victoria with systems installed before 2012 are now getting 71.3 cents per kilowatt-hour of solar electricity exported into the grid. And they will continue to receive this for almost 7 more years.
