Energy Storage system ABC

15-20% of Australian solar customers interested in energy storage

Installation rates of battery storage systems in Australian homes could reach around 1,000 a year by the end of 2014, according to new estimates, as solar households look for ways to make the most of the energy they generate.

Feedback from solar installers suggests that between 15 and 20 per cent of solar customers are enquiring about storage – a rate that is increasing each month.

Australia currently has around 3.4GW of solar PV on household rooftops (and some businesses), but this is expected to rise six-fold out to 2030 as households invest another $30 billion in solar systems.

Many of these installations will look at battery storage because of the structure of tariffs and decisions by network operators, retailers and pricing regulators.

And in response, numerous companies are poised to roll out home energy storage solutions in coming months. UBS recently predicted that households in major Australian cities may find it economic to go “off-grid” as early as 2018. Morgan Stanley predicted a mass move toward energy storage, and warned of an imminent “tipping point”. 
CSIRO noted that half of domestic demand could be met by solar and storage on-site.

The decision by regulators to assign a low “value” of solar exports, and to make such payments voluntary in some jurisdictions, is forcing homeowners to look at how to “self-consume” their solar output rather than export it back to the grid. Battery storage is an obvious option.

Recent decisions by network operators Ergon Energy and Energex to place restrictions on rooftop solar systems exporting back into the grid will do the same. 

Ergon Energy says it is inevitable that households will turn to storage, mainly because it is cheaper than the unsubsidised delivery of centralised power. It will also save the network operator money because it won’t have to build so many poles and wires.

Hello Giles or Solar Choice,
I presently have a rooftop solar system installed in 2007. It is small by comparison to units going in now (10 x 165 watts), however, along with lighting and appliance upgrades, solar hot water plus insulation, our summertime usage has dropped from 12 kwHours per day to 4 to 4.5 kwHours per day. Is it possible to do a comparison matrix of the energy storage options? I understand prices may drop 50-80% by the end of 2016. Still, it would be of major assistance to be able to evaluate the various storage options in the pipeline. Many thanks. Don Craig and family

Hi Don,

We have developed a battery storage comparison whose aim is to help Australians compare the battery storage market quickly and at a glance. You can learn about it here. Other than that we’ve also composed a list of battery storage products available in Australia (which you can see here).
