The Good Solar Guide: 7 Steps To Tiny Bills For Australian Homeowners

Order the Good Solar Guide by Finn Peacock

Almost 10 years ago, I sat down for 2 weeks in Brighton Public Library and put everything I knew about residential solar power systems into my battered old laptop. I used the free Wi-Fi to upload that information to a home-brewed website called SolarQuotes. The knowledge was picked up from working for the Energy Transformed Flagship at CSIRO combined with my broader background in electrical engineering.

Since then, millions of people have visited the site; which has been continuously improved over the years. [Read more…]

Don’t Add Batteries To A 3-Phase Home Before Reading This

3-phase homes and solar battery systems

If you buy the wrong battery system for your three-phase home your electricity bill will not go down nearly as much as you expect. And with the economic return of battery systems being pretty marginal in even the best case scenario, it is super important that your battery gives you the best returns possible. [Read more…]

The Six Biggest Myths About Battery Storage

finn's battery system - energy storage myths

If you are buying a solar battery – go in with your eyes wide open.

I’ve been publishing thoughts on the solar industry since 2009. And since Tesla announced their Powerwall battery to great media hype in May 2015, a lot of those thoughts have concerned batteries.

Unfortunately, a lot of the facts I’ve published about batteries, their economics and their environmental impacts have not gone down well with some parts of the solar industry, generally the parts that have bet their future on selling lots of batteries in the short to medium term. [Read more…]

Tesla Says Powerwall 2’s Return Will Be 8-15%. Really?

Is it reasonable to expect a “8-15% return on investment” on a Powerwall 2?

Last month, Lyndon Rive, Tesla’s Vice President for Energy Products, stood up in front of a large group of people, including me, and promised the Powerwall 2 will deliver a return between 8% and 15%. [Read more…]

Will it be illegal to install a single phase Powerwall 2 from Thursday?

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…]

Billionaire’s Gambit – Why we should accept Musk’s offer.

deal

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…]

Powerwall 2 Full Spec Released: Low cost but ‘unlimited cycles’ warranty has limits.

powerwall 2 spec

The full spec and warranty of the Powerwall 2 reveal a cost per warranted kWh almost half that of its nearest rival.

[Update March 13: Tesla has cancelled sales of the DC Powerwall 2 in Australia and the first installations of the AC version of the Powerwall 2 will now apparently be done in April.]

Yesterday, Tesla kindly sent me the Powerwall 2’s full data sheet and warranty. We already knew the headline specs:

Storage: 13.5kWh

Power: 5kW steady, 7kW Peak

Price: AUD$8,000 + GST and Installation

But there were lots of questions over the exact configuration and warranty details that could make or break Tesla’s shiny new battery. Most of these questions have now been answered.

Here’s what the new specs reveal: [Read more…]

Why over hyping batteries hurts the solar industry.

I feel so strongly about this that I though I’d shout at a video camera about it for 7 minutes. Hit me up in the comments if you think I’m being too harsh.
