Thought a grad course in Energy Systems Modelling would cost thousands? Thanks to COVID you can do a full graduate course for free online.

Worried about how a renewable-powered world keeps the lights on when “the sun doesn’t shine and the wind doesn’t blow”? Interested in energy systems modelling? [Read more…]

To integrate solar power into the grid more efficiently, the grid operators need to know what’s happening with your solar system. That means looking behind your meter.

With 9GW of solar PV installed, Australia’s enthusiastic embrace of household renewables is starting to bump into system capacity issues. As I wrote last week discussing the advent of the two-sided market, the time is coming where the energy sector will need to be able to reach behind the meter and manage the consumer-side resources such as rooftop generated solar electricity.

A set of papers published in the International Journal of Antiquity last month has revealed ancient Egyptians may have had access to a technology that, in our modern world, has only taken off over the last few decades.  [Read more…]

This was our cartoon from way back in 2016 when Tesla originally launched their solar roof tiles. Three years later it may actually be ready, rebranded as the “Tesla Solarglass Roof”.

Persistence has paid off for Tesla, which surprised finance markets with a US$143 million GAAP profit for Q3 2019, on the back of its long-promised and finally-delivered production ramp-up. [Read more…]

Ronald went to the All-Energy Exhibition & Conference in Melbourne. Here’s what he stumbled across.

I just got back from the 2019 All Energy Conference and Exhibition in Melbourne.¹  While there I also snuck across to the the Energy Efficiency Expo next door.  Over the next couple of weeks I’ll write a few articles on what I learned, but for now I’ll just go over some highlights and show some pictures… [Read more…]

SA Power Networks plan to use dynamic export limits to allow more people to get rooftop solar power – whilst maximising allowable solar energy exports. Brilliant.

When the Australian Energy Market Commission (AEMC) released its Economic Regulatory Framework Review, “Integrating Distributed Energy Resources For The Grid Of The Future” (PDF here) last week, media reactions had a pessimistic, almost apocalyptic slant. [Read more…]

A couple of weeks ago, I took a look at a customer’s need to integrate his solar PV controller with his smart home system, and concluded that this industry needs to settle on standard protocols so systems can get smarter. [Read more…]

You’ve probably heard of mono and poly panels. Now there’s a third type: ‘cast-mono’. But what the hell is it?

Silicon is the Queen of solar power.  Some people say Coal is King, but I say our Queen can kick your King’s arse. [Read more…]

Tenants who ‘invest’ in AGL’s Offsite Solar are emotionally handcuffed to their tariffs for 7 years

If you are lucky enough to own an unshaded roof over your head, solar power is a no brainer.

Millions of homeowners have realised this and, for those who have done it right, they are living a life free of energy bill worries for the foreseeable future.

But what about the 30% of Australians who rent? They are seemingly stuck having to pay electricity retailers for overpriced, dirty grid electricity. [Read more…]
