Believe the Hype: Australia's Battery Market is set for eye-watering growth

For quite some time I'd dismissed the hype about the attractiveness of installing grid-connected batteries in Australia. Yes, everyone loves the idea of energy independence, and would love to give the middle finger to the electricity retailers who buy excess solar power at a fifth of the price they themselves charge. But I thought there would be few people willing to spend tens of thousands of dollars to do so. On top of that, though Tesla had created a surge of interest, most PV retailers were struggling to convert that into sales, or had limited product supply options.

SunWiz today released the results of its extensive surveys, interviews, and research into the Australian market for energy storage.

SunWiz's research concludes that there were at 6750 battery installations in 2016, totalling 52MWh. To put this into context, there were 130,000 installations of solar power systems in 2016, meaning that effectively 5% of solar installations included batteries in the past year.

Says Warwick Johnston, Managing Director of SunWiz "6750 installations in 2016 represents exceptional growth in the Australian battery market, coming off the back of 500 battery installations in 2015. What makes it all the more impressive is that most installations occurred in the latter part of the year, setting up 2017 to be another year of remarkable growth". Johnston says "SunWiz expects the market to treble in 2017, suggesting 15% of new solar installations will include energy storage this year."

New South Wales was the #1 location for battery installations, followed closely by Queensland. South Australia has the most favourable market for battery installations, owing to large amounts of sunlight, high electricity prices, and subsidy programs from government, AGL, and SAPN - all of which contribute towards some solar-storage systems having 7-year paybacks before subsidy.

2016 was also the largest year for storage projects. Highlights inlcude the 2MWh installation at the Sandfire Copper Mine, the 1.1MWh community installation at Alkimos Beach, and the ACT auction.

Survey respondents from solar retailers indicated that 70% of sales enquiries for solar also enquire about batteries. Customers are interested in the ability of batteries to become grid-independent, reduce electricity bills, and make more efficient use of their solar panels.

The report, which was based on hundreds of hours of interviews, surveys, and research, provides transparency into what is otherwise a very opaque market. Johnston says "our interviews highlighted the storage market is in its infancy and market education is required. Customer expectations of batteries differ markedly from the capabilities and value proposition of most offerings on the market, and salespeople are also caught up in the excitement. Batteries aren't yet a commodity - one size doesn't fit all and tools such as PVsell can help identify which is the best option for individual customers.

At one point, 2016 looked like an abysmal year for Australian solar. But 2016 turned out to be record breaking year for solar, in many regards. You'll get all the information you need here, but here are some of the highlights.

  1. Though the headline utility-scale figures indicate a come-down of mammoth proportions, it was always going to be impossible to fill the gap left by Nyngan, Broken Hill, and Moree - heavily-subsided projects over five years in the making. However, if we exclude systems exceeding 20MW (Baracaldine being the only project last year above this threshold), there was actually significant growth. There was a record volume of systems in the 5-20MW range: Mugga Lane, Williamsdale, and Dugrussa (Sandfire), as well as growth in every other size category above 100kW.

SunWiz is researching installations that exceed 100kW, as part of our reporting to the International Energy Agency's PV working group, APVI's "PV In Australia", and CEC's "Clean Energy Australia" report. We are the key market analyst responsible for tallying the PV installation volume that was commissioned each year, and we rely on multiple data sources. The STC registry provides the best snapshot of the volume of sub-100kW systems, but for systems over 100kW the LGC Registry isn't as up-to-date or complete. So we track key market announcements, interview leading installers, and survey the market (which is what we're doing now). As you can see from the image below we currently have identified 33 projects totalling nearly 80MW that we understand have been commissioned in 2016.

We'd greatly appreciate if you can let us know if you've installed a PV system over 100kW that was commissioned in 2015 that isn't listed below. Projects are listed in descending order of capacity. Please email project details to

The upgrade bonanza: NSW PV Retailers start targeting Solar Bonus Scheme customers for system upgrades

All solar bonus scheme households within the best Sydney postcode to target for system upgrades have been individually identified and mapped, with more top postccodes to follow and most available upon request. 150,000 opportunities totalling up to 420MW of PV and 1000MWh of storage,

It won't come as much news that NSW PV retailers are eagerly awaiting a mini-boom come 1/1/2017. That's the date when 150,000 customers under the Solar Bonus Scheme lose their 60c/kWh gross feed-in tariff, and instead receive 10 times less value for their excess solar power. The first, most sensible option for these customers is to switch their metering across from gross metering to net metering, so that the solar power they self-consume during the day at least offsets their daytime tariff of 20-52c/kWh. But these households, most of whom have been receiving a cheque from their electricity providers are in for the worst bill shock they've ever experienced. And while they couldn't upgrade their PV system without forfeiting their generous 60c/kWh feed-in tariff, when the SBS program ends on 1/1/2017 they will also be unshackled from upgrading.
