China win #1 solar panel for 2013 (although US firm Sunpower was robbed!)

Note: this post was written in 2014 and is out-of-date. To get my latest recommended solar panel brands please read my constantly updated Solar 101 Guide.

Hot off the German Press: industry bible Photon Magazine has announced the winners of its 2013 solar panel test. Basically, a bunch of Germans in white coats mount a gazillion solar panels in a field in Germany and measure their power output over 12 months.

At this point, I must point out that 3 separate Sunpower models would have won all of the top 3 spots, but they had to remove them from the table due to a testing machine malfunction…so it is by no means a totally fair test. But it is useful to see which brands perform well despite this rare cock up from our German friends.

So here here are the top 20 for 2013: [Read more…]

Sky’s the limit for solar cell innovation as new breakthrough aims for 50 percent conversion rate

50 percent efficiency

Yes you read that right : 50%

One of our favourite subjects — solar cells and more specifically solar cell innovation and breakthroughs — is covered in this week’s SQHQ spray readers.

I think I’ve mentioned, in a previous rant in these pages, one of the enduring memories I have of seeing the famous environmentalist/author/activist Professor David Suzuki in 2007 was his rhetorical question that kicked off the night: why wasn’t every house in Australia covered in solar panels?

If your Chinese solar panels are not on one of these lists, be careful!

chinese solar panels

Some Chinese panels are top quality. But which ones?

A lot of people are wary of Chinese solar panels. China doesn’t exactly cover itself in glory with some of the low quality junk it manufactures. But, as I have said many times before, China also produces some fantastic quality stuff.

Need examples? I bet the device you are reading this blog on was made in the People’s Republic. The Macbook Pro I am writing it on certainly was and it is impeccably put together (the laptop – not the blog!). [Read more…]

Will this incredible solar innovation by Ford make Holden irrelevant?

Those 3 x 100W Sunpower panels could power 75% of your trips.

Last week we discussed how remarkable innovation in the renewable energy sector will change the way  energy is sourced in buildings such as office blocks and factories. We looked at how recent developments in photovoltaics allow office windows to be both transparent enough to let in sufficient light, as well as sensitive enough to act as efficient mini solar panels.

This week sees us delve into the traditional Holden vs Ford wars, though with a renewable energy twist. [Read more…]

From Russia WIth Love: Perovskite could reduce solar costs by 75%

One of the many advantages of solar energy is its charge down the cost curve as new technologies outstrip old in performance and cost. This week at SQHQ we’re dusting off the crystal ball and looking into the future of solar power. Specifically we’ll be checking out perovskite; the “new kid on the block” (with all the rave reviews). Perovskite is considered to have the potential to replace silicon in solar cells. [Read more…]

8 things to look out for when buying cheap solar panels

November 2, 2013 2019-02-12T10:55:25 by 61 Comments

There are a hell of a lot of companies offering cheap solar panels right now, and as with all free markets, that is driving down the prices and the margins of solar power installers and suppliers.

The question I get asked the most is this:

“How do I tell if this deal from XYZ solar (which is heaps cheaper than anyone who quoted through your site) is too good to be true?”

So here’s your answer: [Read more…]

Are “Munchen Solar Panels” Actually German? And Are They Any Good?

September 18, 2013 2014-01-05T18:11:39 by 8 Comments
A German and Chinese Dude

Are Munchen Panels German or Chinese or Both?

Recently I’ve been getting a lot of emails along the lines of:

Hey Finn, Have you ever heard of Munchen Solar Panels? Are they any good? I really want “German Engineered” Panels and these look better than any of that Chinese engineered rubbish!

Well, the short answer is this: “Munchen Solar? Never heard of them. (and btw there are some great Chinese panels out there..)”

But after the quadzillionth email asking the same thing, I thought I’d do some digging to try and discover why there is a sudden spike in interest for these I’ve-never-heard-of-them-before German sounding solar panels. [Read more…]

Newly crowned as net producer, PV looks to full payback of dirty energy debt

holy grail film poster

Yes folks, we’ve reached the holy grail.

Always rewarding to bring readers good solar news and this week’s offering is just that. The achievement/milestone/breakthrough (call it what you will) is that the amount of the energy produced by global PV solar power has surpassed the amount of fossil fuel energy needed to make the panels.

It seems fairly certain that a tipping point has been reached, or will be reached in the very near future, say researchers at Stanford University. [Read more…]

Trina Solar Panel Review Shows Great Performance in Hot Aussie Conditions

The latest Trina solar panel review ticks a lot of boxes

Thinking of putting Trina solar panels on your roof? Then finding a review that you can trust is critical. After all, unless you are an uber solar geek like me you probably have never heard of the Trina brand before (they are one of the biggest solar panel manufacturers on the planet by the way).

Reliable, honest solar panel reviews are very hard to come by. Why? Firstly because properly testing a solar panel takes at least a year – so that you get all the seasons. Secondly it takes a big investment in carefully calibrated measurement hardware. [Read more…]

We’ll miss you Bosch Solar

Yesterday was a really sad day for fans of top-of-the-range solar panels. German giant Bosch announced that it could no longer bear to haemorrhage any more cash from its solar division. So it is going to shut the whole shebang down ASAP. [Read more…]
