Unless your local electricity network provides a local variation to a new Australian Standard that becomes mandatory on Thursday, it may be illegal to install a Powerwall 2 plus solar on a single phase. [Read more…]

A Reader’s Frustrations With The Enphase Enlighten Monitoring System
Enphase panel monitoring is a great feature. But some Enphase installers flat out refuse to enable it.
There are many people in this world who enjoy monitoring the output of their rooftop solar systems.
But other people – not so much. For example, I don’t think my parents have checked the output of their system since they got it. My father just looks at the electricity bill every three months and grunts, “Power bill low. Is good.” And then goes back to making stone tools.
But for those who enjoy the heady pleasures of solar system monitoring, modern technology can provide the fix you’re looking for. [Read more…]
OneSolar Review. One Word: Avoid
OneSolar make a lot a lot of claims on their website that just don’t stack up.
When it comes to choosing solar panels and inverters, we recommend sticking to well known brands.
Over the years we’ve seen lots of obscure panel brands hit Australian shores, often with slick websites, and almost always with dubious claims of being ‘engineered’ in anywhere-but-China.
Our experience is that the quality of these mysterious brands is often poor, and if they fail a few years down the line it can be very hard to find the company that originally imported or manufactured them. [Read more…]
Billionaire’s Gambit – Why we should accept Musk’s offer.
Last Thursday in a trendy re-purposed Substation near Melbourne, Elon Musk’s cousin Lyndon Rive claimed he could solve SA’s energy woes in 100 days.
How?
By installing 100-300MWh of batteries.
Big Call.
A day later, via Twitter, Aussie tech billionaire Mike Cannon-Brookes asks Musk if he’s serious about “100MW1” of batteries in 100 days. Musk wagers he’ll deliver and install them in 100 days or it’s free. [Read more…]
Cost Of Powerwall 2 Drops 9% Overnight
The Tesla Powerwall 2 is now $800 cheaper in Australia.
Tesla appears to be unsure about how much to charge Australians for the Powerwall 2.
Or maybe they are sure, but confused about how the Australian dollarydoo works.
Perhaps they’ve been confusing it with the New Zealand doubloon or the Fijian guilder?
I know I often do.
“Crikey! 900 dollarydoos to the New Zealand doubloon and 6 centaroos to the Fijian guilder!”

Election renewables news roundup Week #2
Whilst pollies spent the week campaigning, Aussie researchers made the biggest breakthrough in solar efficiency in years.
Used to being marginalised during election campaigns, the renewables sector hasn’t exactly sprung to the centre of attention during the latest most important election since the last one. However there are signs that the two major parties are taking notice of the Australian electorate’s overwhelming support for a strong renewable energy policy as we dip into the election renewables news roundup for the second week.

Solar thermal electricity could generate 12 percent of world’s energy by 2050 says report
These mirrors at CSIRO in Newcastle can focus the sun to create superheated steam. That is the same pressure and temperature of steam that a coal fired power plant creates. Amazing.
A major report released last week has predicted solar thermal electricity (STE) has the potential to power six percent of the world’s energy by 2030 and 12 percent by 2050. The scenario is based on the most positive outcome where global capacity of STE (aka concentrating solar power) reaches 1,600 GW by the middle of the century. [Read more…]
Powerwall Vs. Lead Acid Batteries. Which is best for off grid?
Does the Powerwall make sense for off grid applications?
I recently wrote about how my parents could save money by going off-grid in sub-tropical Queensland under close to best case conditions, and how it made no sense at all for them to do this as the return from having grid connected rooftop solar is so much better.
The recently announced Tesla Powerwall doesn’t change this. However, it will still be a very useful option for people who have no choice other than to live off grid, and for those who want to go off grid for non-economic reasons. It has a number of advantages over currently used lead-acid batteries, and in my opinion, for many applications the Powerwall knocks lead-acid batteries into a cocked hat, which will soon be squashed very flat, as lead-acid batteries are really heavy.

Solar breakthroughs by the dozen but what of the future?
The breakthroughs just keep on comin’
This week two news items have proved that innovation in the solar energy sector is not only alive and humming but well on the way to shaping our energy future. The first is based on nothing new. Indeed it was originally proposed in a 1941 story by science fiction author Isaac Asimov.
With climate change now threatening our very survival as a species — according to the more downbeat of scientific studies — and with a general lack of political will to do anything about it, it may take something completely from left field to save the planet. Enter solar energy and the Asimov proposal.
