There’s been plenty of talk about how Australian solar households are warming to the idea of battery storage, but little concrete data to back this up. Until now.

A new report from solar analysts, SunWiz, has revealed almost 21,000 behind the meter energy storage systems were installed in Australia in 2017, a three-fold increase on the year before.

On top of that, the report finds that 12 per cent of the 172,000 new solar systems installed in the booming 2017 market included a battery, up from six per cent in 2016.

But what does this trebling of battery storage uptake mean? Is it a sign that batteries now make economic sense to the average Australian household?

After an extended period of research, SunWiz has released its much-anticipated Australian Battery Market Report for 2018.

The report details the inner workings of the Australian energy storage market for 2017, including: 

  • The numbers and capacity of home energy storage batteries installed in each state in 2017
  • Key news items and projects for 2017
  • List of key projects for 2017 and those coming in 2018
  • Pricing trends and forecasts, plus subsidies available in Australia
  • Financial analysis of batteries for every Australian DNSP
  • Research on customer purchasing motivations
  • Manufacturer public announcements of volume
  • Forecasts for 2018 and beyond

Do you remember the predictions of solar industry consolidation? Predictions that eventually the market would consolidate from 4000 businesses to four or forty major solar companies serving the Australian market?

The logic seemed sound: the solar market was contracting year on year from 2012-2016, and the residential backbone was eroding even faster. Along with it, system prices kept falling, meaning revenue was plummeting even as operating costs and red tape rose.

America had seen the market share of the top player exceed 40% - wasn’t this Australia’s destiny? Wasn’t Origin or AGL or SunEdison or True Value Solar going to sweep away all the small businesses? Force the exit of smaller players either by out-competing them or by buying them out?

What was a small business to do, except grimly hold on and hope that the others went bust before them? Grimly holding on meant matching your competitors prices at a level that was absurdly and unsustainably low.

Or a small business could pray each night that a buyer would come along. Apart from a couple of fellas who got lucky - selling their business at the height of the solarcoaster and returning to solar in 2017’s boom year, most that discussed selling up discovered their business value was practically worthless. The value of their pipeline was more than offset by the potential liability of past installations, leaving business processes being the only value in a solar company - processes that weren’t particularly robust, easy enough to recreate, and processes that a buyer would find difficult to integrate into their own.

Now there have been plenty of businesses that have gone bust in the past 5 years. This would suggest a degree of industry consolidation has occurred through attrition. However it seems that an equal number of businesses have been started.

The charts below prove that industry consolidation has not occurred. Indeed, SunWiz’s market assessment demonstrates that the opposite has occurred: the solar industry is now more competitive than ever, with no single company able to dominate.

The Australian solar industry should take a collective bow. Well, catch its breath first, and then take a collective bow. 2017 was a magnificent, record setting year for solar installations, and many people were still up on roofs installing over the summer break. It may actually not be possible to pause to catch breath, as we're already hearing that January 2018 is notably busier for commerical sales than in past years.

SunWiz has a crazy busy January too, compiling all the data for the 2017 Year in Review, and for reporting to the CEC and IEA. But we can't contain our excitement at the figures we're seeing, so we're taking a moment out to publish some pretty impressive data (even if we do say so ourselves).

So, here's some highlights from the 2017 Year in Review, to whet your appetite:

  1. Installation Tally
  2. Incredible Growth
  3. Robust Growth across the nation
  4. Residential Rebound and Commercial Skyrocket
  5. Solar Panel Imports worth $1,200,000,000
  6. Highlight #6: Some fantastic news

All the glorious charts illustrating these highlights follow...

Even before it had come to a close, 2017 was a record breaking year for Australian PV. Almost 1.1 GW of rooftop PV was installed in the STC market and at least another 0.1 GW of PV above 100kW was commissioned. We haven't finalised our numbers, but this means at least 1.2GW of PV was installed in 2017; quite possibly 1.3GW.

Many businesses worked right up until Christmas, and some even worked up until 31st December in order to get installations completed before the STC deeming period reduced. Hopefully everyone has had a refreshing break, no doubt during which the question was pondered: will it be a Happy New Year for Australian PV: can we sustain or even increase volumes in 2018, or will volumes dive?

Well if our twitter poll is anything to go by, 2018 will see an increase on 2017's volumes in the rooftop market, with the overwhelming consensus being an increase in the volume of rooftop PV that will be installed. 

Businesses are confident, at least. But is their confidence well founded? Let's examine 2018.
