Trina have set a record 19.86% aperture efficiency for polycrystalline.

Trina Solar announced a new world record for solar panel efficiency on Tuesday. The announcement was made via a press release that was mostly comprised of words.

But that wasn’t all it contained.  Oh no, this press release was far too important to get by just using them. It also contained numbers, punctuation, and percentage signs.

Exactly what the particular arrangement of all these ingredients they poured into their press release actually means is a little tricky to work out. But, for your elucidation, I shall now attempt reading comprehension and I am not even going to use a net. [Read more…]

How To Clean Solar Panels

I have already written about why it doesn’t make sense to pay people to clean your solar panels. I also wrote it doesn’t make a lot of sense to clean them yourself. Once you add in the value of your time, the chance of falling off the roof and killing yourself, and how cleaning panels usually only adds a couple of percent to their average output, it is not really worth it.

Is Solar Panel Cleaning A Waste Of Time And Money?

Solar Panel Cleaning – It’s A Dirty Job, But Nobody Has To Do It

The day your solar panels are installed is the day you will get the best performance out of them.  After that it is all down hill. Admittedly, it is a very shallow hill and it might take over 40 years to get to the bottom, but day one is going to be as good as it gets.

One of the reasons for this is dirt. As soon as your panels are out in the open in the clean air, or not so clean air, dust will start to settle on them, blocking sunlight, reducing their efficiency, and costing you money.

The obvious solution is to pay someone to clean those panels, or get out there and clean them yourself. And sometimes this obvious solution will be a sensible course of action. If a dust storm has covered your panels in dirt or pelicans have had a poop party on your roof, then it’s a pretty good idea.

But most of the time solar panel cleaning is not worth it. [Read more…]

Solar Panels By The Sea And Corrosion Resistance

August 11, 2016 2024-01-03T18:59:18 by 19 Comments

If you are putting solar on a house by the sea then I’m jealous! And I also need to tell you about the IEC-61701 standard.

Oh, I do like to be beside the seaside,
I do like to be beside the sea…

Ever wonder why you never hear a robot singing that song? I’ll tell you why.

Two words: corrosion!

Sorry, that was one word. Two words – bad corrosion! [Read more…]

Why Oversizing Solar Panel Arrays Is A Smart Move

August 9, 2016 2024-04-08T10:18:05 by 87 Comments
house with lots of solar panels

Did you know you can add panels up to 133% of your inverter capacity? Read on to discover why oversizing solar is a smart move (as long as your roof is big enough – unlike this guy’s).

Installing rooftop solar systems with a total panel capacity greater than the inverter capacity is usually a very good idea.  It will certainly save you money, but it can also help get around the restrictions many Australians face on the size of inverter they can connect to the grid. [Read more…]

Seraphim Solar Panel Review: Heaven or Hell?

August 5, 2016 2025-01-02T10:06:15 by 23 Comments
seraphim solar panels being reviewed by Ronald

Ronald looks into Seraphim Solar Panels. Yes, Ronald really looks like that.

One solar panel manufacturer who seems to be popping up a lot recently is Seraphim Solar. On the plus side they appear to make top quality panels which have done a good job of impressing people, receiving an average rating of almost 4.9 out of 5 from our customer reviews.

But they get a black mark, for not having an Australian office despite having been sold here for some time. That fact could be a showstopper for some solar buyers as there are plenty of good solar panels for sale in Australia with fully supported Australian offices

Update 10 July May 2019: SAE group is an importer of Seraphim panels and responsible for manufacturer warranties for panels they imported, but are not the only importer of panels and not responsible for the manufacturer warranties of panels brought into the country by other companies.

Dead Set Solar Legends Donate 30kW Solar System To Kid’s Charity

kid and solar panels

The Australian solar industry. It’s full of kind, generous people.

Do you love children?

I do.

And this is not a lead in to a stupid joke where I say, “…with tomato sauce”.

In fact, all things  considered, I find children to be about exactly as annoying as I find adults.  So if you’re human, no matter what your age, you’re okay as far as I am concerned. [Read more…]

SunPower X-Series Panels Set New Efficiency Record Of 24.1%

June 30, 2016 2017-04-18T17:44:37 by 5 Comments
sunpower panel efficiency

Sunpower X series panels have breached 24% efficiency.

I have previously mentioned SunPower makes excellent solar panels. This definitely includes their uncanny X-Series, which are a high efficiency, high reliability, line of monocrystalline panels. In January they broke the record for most efficient solar panel with a figure of 22.8%. And now, less than six months later, they have increased that by an impressive 1.3 percentage points to 24.1%.

I can only marvel at the improvements in PV efficiency that have occurred so far in 2016. Just six months ago I would have said the chance of any panel exceeding 24% efficiency this year would have been a long shot, but lately improving efficiency has been smashing records like an unstoppable juggernaut.

Hanwha Q Cells Q.ANTUM Solar Panels Smash Record For Polysilicon Efficiency

June 23, 2016 2017-04-18T18:04:56 by 6 Comments
q-cells solar panel efficiency

Q-Cells clever Q.ANTUM design of solar cell promises better efficiency for cheaper, multi crystalline panels.

Hanwha Q Cells has smashed the record for polysilicon solar panel efficiency like a robot driving a steel fist through a fragile silicon wafer. They have achieved an efficiency of 19.5% with a standard sized panel, 1.67m by 1m in size. The module is 301 watts and Hanwha claims it was produced using standard processes on industrial scale production equipment, which means it should be ready to go into production. [Read more…]

SunPower Solar Panels: One of the best panels lots of money can buy

June 6, 2016 2017-11-10T14:01:38 by 83 Comments
sunpower solar panels

SunPower make very good, very expensive panels.

SunPower make some of the best solar panels in existence. Or at least some of the best on this planet. Perhaps Spectrolab regularly shoots better ones into space to mars or somewhere, I don’t know. But if you want to buy something that is meant to go on a roof and not a space probe, then SunPower solar panels are hard to beat.

Now note that I did say some of the best and not some of the cheapest. If you haven’t worked out that the words cheap and best don’t normally go together, then I have a really low quality laptop held together with superglue and wooden rulers that I’d like to sell to you at a really high price.
