Batteries Beginning to Blitz It

With State subsidies on the horizon in Vic and SA — interest in batteries is heightening.

A report by the Sunwiz solar consultancy indicates that 70% of homeowners with an existing PV array would like a battery retrofitted with it.

UMR's research confirms that number. They found 69% are interested in adding batteries, 26% very interested and 43% fairly interested. And that was before the really recent relevant announcements of upcoming subsidies in SA and Vic.

The statistics show that investment, not just general interest, has increased as well.

Data from Sunwiz demonstrates that in the first six months of 2017 alone the number of solar storage solutions installed had already matched the total number for all of 2016. 2017 ended by tripling the 2016 figure. 12% of the 172,000 solar systems installed in 2017 included a battery — up from 5% in 2016.

There are presently 32,500 batteries installed across Australia all told. 28,000 of them are grid connected.

To break battery installations down by State,

Local Government Policy:

Past Home Improvement Scheme included up to $4,000 in vouchers for solar and battery installations;

Smart Energy Grants

All figures from the Clean Energy Regulator's data for 2010-2017.

The trend is set by rising electricity prices, lowered cost and heightened quality of batteries, solar homeowners who saw the return on their array and still have significant residual nighttime usage, strong branding by key players (special mention to Tesla & sonnen) and, more recently, government incentives.

For fairly obvious reasons Australia is set to be a key market for PV paired battery storage solutions. Insolation per metre square, relatively longstanding and developed solar industry, high tariffs and differential between export versus import elecricity prices. Australia's ideal really.

Projections suggest that we should see anywhere between 150,000 to 450,000 batteries installed nationally by 2020, according to the Smart Energy Council.
