If you asked me what type of inverter your rooftop solar system should use:
- A string inverter — like most solar systems in Australia, or…
- Microinverters — a little baby inverter that goes under each panel.
I would say…
Microinverters Perform No Better Than String Inverters: French Study
Russian Invasion Makes IEA Nuclear Predictions Impossible
Last year the International Energy Agency (IEA) published a long report where — among other things — they predicted the rate of new nuclear construction would roughly double. When I first read this, I considered it nearly impossible. But now Russia has invaded Ukraine, I consider it flat out impossible. [Read more…]
Feed-in Tariffs & Electricity Prices Likely To Rise In 2022. Here’s Why.
Wholesale electricity prices increased across most of Australia this financial year. Retail electricity prices should soon follow. [Read more…]
Reduce Gas Use For Ukraine!
Do you want to weaken Putin’s hand while making European nations more willing and able to cope with disruptions in their energy supply?
Of course you do! One simple way to help Ukraine is to stop using gas.
You can start immediately. [Read more…]
Do We Have Enough Critical Minerals For A Solar & Battery Powered Future?
Last year the International Energy Agency (IAE) published a report titled…
The Role of Critical Minerals In Clean Energy Transitions
I recently dived deep into its 260 pages to see if a shortage of critical minerals threatens the world’s transition to a renewable future. [Read more…]
Is Solar Still Worth It – If You Are Single?
I’m So Lonely! Will Solar Panels Fill The Aching Void In My Heart? And Do I Have To Pay Them Folding Money?
If you ask me,
“Hey Ronald, should I get solar power?”
My answer will be, [Read more…]
Which Solar Panels Can Be Installed Flat Without Voiding Their Warranty?
Solar panel warranties have lots of interesting conditions in them. Some require panel cleaning while others forbid any shading of any panels. [Read more…]
Solar Panels On A South Facing Roof Can Pay Anywhere In Australia
TLDR: Can you put solar panels facing south in Australia? Hell yeah!
In 2010, when Australian rooftop solar power really started to take off, nearly every Australian solar system faced north to maximise energy yield. But today, on an unshaded roof, panels facing any direction can pay for themselves. This includes the ‘worst’ direction: south. [Read more…]
Tonga Eruption Won’t Cool Planet Or Reduce Solar Output
After I heard about the Tongan volcanic eruption, the first thing I did was determine if the Tongans I knew were all right. While conditions there are serious, they aren’t as bad as they could have been, so they’re probably okay. Australia and New Zealand are sending relief, which is a relief. [Read more…]
EV Ranges In The Real World — How Far Will You Really Go?
Electric car manufacturers know exactly how much range drivers get on average from a full charge. Despite this, they continue to give inflated figures based on unrealistic tests rather than a realistic real-world range. [Read more…]
