West Australians are increasingly seeking the benefits of new-generation batteries as the State’s generous solar feed-in tariffs start to disappear, reports Redflow’s new WA partner Leith Elsegood.
WA homes that installed solar systems a decade ago are already losing the 40-cents per kilowatt-hour (KWh) feed-in tariff, introduced by the State Government to encourage the installation of solar panels. The 10-year feed-in tariff will end in 2021.
Since 1989, Mr Elsegood’s company, TIEC Services, has installed solar photovoltaic (PV) systems and energy storage systems throughout WA, at remote communities and, more recently, in high-end homes in the Perth metropolitan suburbs.
TIEC Services recently signed up as installer of new-generation Redflow energy storage batteries for Perth and WA. Already, the company has won large, residential solar and energy storage contracts with Redflow’s ZBM2 batteries. “The Redflow battery is ideal for WA conditions, handling the dry heat and the great distances in remote regions,” Mr Elsegood said.
“We have installed a lot of batteries over the years, especially in remote areas, but the problem with lead-acid batteries is the heat and their size. For 40 kWh of battery storage in lead, you need a cargo-size container. The newer lithium batteries create complexity, especially for a large system, and they lose their storage capacity over time, which makes them difficult to plan with.
“With Redflow’s zinc-bromine flow batteries, you get a lot of kilowatts for the battery. They keep their storage over time. They handle the heat. They can work hard, charging and discharging consistently at three kilowatts (kW) and up to five kW, so it is straightforward to design a large storage system.
“I’ve had an eye on this zinc-bromine battery technology since the early days. Now I think the time is right for them. Everyone is starting to recognise that we were over-sold on the benefits of stand-alone solar as the great feed-in tariffs disappear over the next couple of years.
“At that point, people will see that their home solar is producing a lot of power but they’re not getting paid much for it. Using Redflow batteries, we can design a system that has a lot more benefit for the homeowner during the evenings. We are getting a lot of interest in this at the moment.”
Redflow National Sales Manager Tesh Solanki said TIEC Services provided proven experience for customers in Western Australia. “Leith gives us good coverage in Perth and WA in general,” he said.
“TIEC is a successful business with a strong focus on sustainability, so Leith brings both passion and the proven expertise and capability to match it.”
