Has your solar panel’s ‘product warranty’ has been magically transformed from 10 to 25 years thanks to Australian Consumer Law?
When people ask me about solar panel warranties, I tell them to look at the product warranty. This is usually for 10 or 12 years.
I tell them not to worry about the performance warranty, which is normally for 25 years or sometimes 30. You see, while most manufacturers are happy to honor their product warranties, not all of them expect to replace solar panels that fail while they are only covered by their performance warranty.

Will Trump destroy the US clean energy industry?
Donald Trump has won the US Presidential election. The people of the United States of America have spoken. They haven’t spoken very well, but they have done it. And since they will have a guy in charge who never shuts up, they’re not likely to stop now.
Tesla’s solar roof tile announcement raises more questions than it answers.
On Saturday the 29th of October, Elon Musk made an announcement that thousands of Australians were waiting to hear.
He spent 37 seconds making that announcement.
Then he spent most of the rest of the time spruiking Tesla’s new solar tiles. [Read more…]
The lovely looking Sonnen Battery. Don’t ever put one in your living room. That would be silly.
Sonnen is a German company who have been making home batteries longer than Tesla. They were originally known as sonnenBatterie but shortened their name and called their battery system that. Its full name in Australia is the sonnenBatterie eco.
Their system is 100% made in Germany using 100% made in Japan batteries and their inverters appear to be 100% made in either Spain or Bulgaria. All other components are 100% made in whatever countries they were made in. [Read more…]
Elon Musk proclaims the coronation of Powerwall 2.0
Today at 12:15 Eastern Standard Time, Elon Musk announced the arrival of the Tesla Powerwall 2.
Some people were enthusiastically looking forward to this announcement, but I was not. I fully expected to be underwhelmed, and as soon as Musk finished his two or three sentences on the actual system, I felt a near fatal lack of enthusiasm sweeping over me. [Read more…]
SolarWatt’s German homepage claims their panels are “Perfekt”. That’s a big call, but their warranty certainly seems as good as it gets.
When it comes to product warranties for solar panels, the American company SunPower has long been king with one that lasts for 25 years. Not only will they replace any of their panels that fail in that time, but they will send people around to install a new one free of charge and cart away the corpse of the dead panel for autopsy to discover why it died so young.
But SunPower is no longer king. They have been dethroned. Their quarter of a century product warranty has been beaten by the 30 year product warranty Germany’s Solarwatt has placed upon their double glass panels, which is three times the 10 year industry standard.
That is a very long time. With the average age of first time home owners in Australia now around 38 years, people could buy a set of Solarwatt panels for their first home and they won’t be out of warranty until after they retire. And maybe they’ll die of old age before any of their panels start to fail.
While in practical terms for most homeowners there is not a huge difference between a 25 year and a 30 year product warranty, But I am very impressed with the confidence Solarwatt has in their solar panels and I am interested in seeing if SunPower will eventually extend its product warranty to meet or beat theirs.

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…]
Are these 3 little chips all you need to optimise your panels for maximum energy output?
Maxim Integrated is a Californian electronics company that has been going strong for 33 years and has only ever been delisted from the Nasdaq Stock Exchange once. As you may be able to tell from their name, they like to integrate things and have developed a way to optimise the power from individual solar panels using 3 tiny chips embedded in the panel.

You can buy 60kWh of storage in a Chevy Bolt for a similar price to 60kWh of uninstalled home battery packs.
Looking to buy some LG Chem batteries but don’t want to pay full price? In that case, I have a little scheme you might be interested in.
If you want to, you could buy an LG Chem RESU6.5 battery system which will set you back around $1,000 per kilowatt-hour of storage. Or you could do a little better by buying a RESU10 as that will only cost you around $900 a kilowatt-hour. But if you follow my advice you can net yourself LG Chem batteries for only $822 a kilowatt-hour.
There is a slight drawback to my plan in that you have to buy 60 kilowatt-hours of batteries to get them for that price. But trust me, it’s well worth it because if you buy these batteries you get a free stereo system! There is no denying that’s a sweet deal. [Read more…]
