Does Rooftop Solar Hurt The Have Nots?
Do solar rebates result in the poor subsidising the rich?
If you spend a significant amount of time on the internet, which I can’t recommend as it is a silly place, then you may have come across people who claim rooftop solar is an enormous scam that depends on government subsidies unfairly taken from those who can’t install it, or choose not to. [Read more…]
When Electricity Price Hikes Don’t Improve The Economics Of Batteries
Do rising electricity prices always improve the economics of batteries? No. Read on to discover why. (And don’t stand on your roof without wearing an approved safety harness – especially if you are balancing giant golden scales on your head.)
I’ve already written on how electricity prices are set to rise substantially.
Because Australians will soon have to shell out like an evicted hermit crab when it comes to grid power, both the good and bad mainstream media are declaring that rising power costs make buying batteries more attractive.
Unfortunately for fans of shock boxes this is unlikely to be the case. Counter-intuitive I know. But bear with me. [Read more…]
Tesla Solar Roofs Are Very Expensive And Their Warranty Is Far From Infinite
Infinity Warranty? As Chuck D once said. Don’t believe the (Tesla) hype.
In October last year, Tesla announced they were making tiles with built-in solar cells that would allow a roof to generate electricity without the need for solar panels. Installations of these solar roofs will start in the United States in June and you can go to Tesla’s Australian site and slap down a $1,310 deposit to reserve one. Tesla says they will be available here in 2018 and, given their record of meeting their own self-imposed deadlines, they should definitely arrive before the heat death of the universe. Just so long as they don’t get cancelled like the DC Powerwall 2. [Read more…]

SMA’s Sunny Boy: Under The Hood. Chinese vs German Manufacturing
2 x 5kW SMA Sunny Boy Inverters. One made in China (SMA SB 5.0-1AV-40), one made in Germany (SB5000TL-21). How do they compare?
SMA have released a new single phase inverter. They kept the same joyful name of “Sunny Boy” however the model has changed from what was known as the “dash 21” to the “dash 40”.
But let me tell you a well-known secret about the SMA “dash 40”. The respected German manufacturer is manufacturing these new SMA inverters in China.
Bombshell.
Has this turned the single phase model of SMA inverters into a cheap Chinese inverter? To find out, I bought myself a 5kW Chinese-built SMA “dash 40” and pulled it apart to compare it to the 5kW German made “dash 21”.
In this post, I’ll first look at the external features: the “smart screen”, the Sunny Home Manager, and the inbuilt DC isolator.
Then I’ll look at the internal build quality, and where the different components are manufactured. Finally, we’ll discuss the after sales service and warranty of SMA. [Read more…]
