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…]
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.

Down, down, solar panel prices are going down!
When someone of the stature of Martin Green says the cost of solar PV technology will halve again by the next decade, you sit up and take notice. Even more so when he says solar will be the world’s most popular energy source by 2050.
For the University of New South Wales’ Prof. Martin Green is considered one of the world’s leading PV researchers. His department’s technological breakthroughs in silicon cell efficiency have not only given us the solar panels we know today but also put Australian PV research at the centre of world PV technology.
“The costs of solar will halve again by 2025 is my prediction,” he told a conference in Sydney on Wednesday. “We are at 60 cents per watt manufacturing now but we will get down to 30 cents per watt some time before 2025.”
Sologic, a company based in Israel, has developed a series of solar panels in a tree branch formation with the aim of providing public areas with a place to recharge devices and surf the web using free solar energy. The aim of the eTree is to provide green energy and shade whilst providing a environmental awareness and a sense of community. Check out pictures and a full article on the eTree here: Sologic Unveils the First Ever Life-Sized eTree Charging Station
LG Electronics USA displayed their new LG X ACe Module monocrystalline AC solar panel series last week at the Solar Power International Expo. LG’s newest solar power products are lighter weight, maximize AC-power output, and allow more flexibility for installation.

Can LDK drag itself out of Bankruptcy?
Another large solar panel manufacturer appears to be in serious financial trouble. Bloomberg is reporting that LDK Solar, the world’s largest producer of wafers by capacity, has put it’s US operations into bankruptcy with over a billion dollars of debt. [Read more…]
What do we do with gazillions of old, toxic car batteries? Simple. Turn them into cheap solar panels of course!
Cheap solar panels made from old car batteries?
Yup! That is the latest clean energy recycling breakthrough from researchers at the Massachusetts Institute of Technology (MIT). And the verdict at SQHQ is “GENIUS!”.
Some solar companies are claiming that their Tier 3 panels are really Tier 1. How can you identify real Tier 1 Solar panels?
For many years now I’ve been banging on about “Tier 1 Solar Panels”. My recommendation has always been that you should spend a few hundred dollars more for Tier 1 panels, so that you can massively reduce the risk of having crappy solar panels installed on your roof. [Read more…]
If you’ve been offered really cheap solar panels, please check that they are not grey imports.
Recently, a number of people have asked me about parallel or ‘grey’ imports of solar panels.
Parallel imports are defined as products (in our case, solar panels) that are imported unofficially by someone other than the manufacturer or their official Australian distributors.
Interestingly, in this day and age with so much online and internet based trade, the lines on this issue have become a little blurred. Some manufacturers will supply you directly with their product, but the majority do not. Most panel manufacturers have carefully developed formal partnerships in place with Australian companies who distribute their panels and provide technical and warranty support for those panels.
Why is parallel importing a problem? [Read more…]

Both ends of solar panel innovation are covered in this and next week’s solar rants readers. These courtesy of heads ups provided by our very own Finn Peacock and SolarQuotes reader and follower Sad Clownfish.
By both ends I mean solar power from the impossibly small to the…well stratospheric.
Let me explain. [Read more…]
