The Boom of Energy Storage Systems

Energy storage systems were the buzz words in 2015, with everything from radio, TV, and newspapers featuring their impending popularity. Now with the start of the New Year rapidly disappearing behind us, and the hype only increasing, we’re outlining what the buzz is about.

What are Energy Storage Systems?

When the sun’s radiation is captured through a solar PV system, it is then converted from DC electricity into usable AC electricity to power homes and businesses. Usually, any excess energy that is created is sent back to the grid to be sold, and any extra energy needed from the consumer can be bought from the grid.

Energy storage systems offer an alternative to this process, giving consumers the ability to store their excess energy for later use, such as during periods of bad weather, or high usage. By using their own stored energy, consumers can become less dependent on buying excess energy from electricity companies, and potentially save money.

Which Brands?

Energy storage systems come in a range of sizes, weights and aesthetics from a large variety of brands. Below is a quick rundown of some of our favourite known brands, and what they have to offer.


The LG RESU is a light-weight, high density, lithium-ion battery from leading electronics manufacturer LG. With a nominal capacity of 6.4kWh and the ability to expand up to 12.8kWh the LG RESU is the ideal battery for on-grid storage applications. This battery is one of the smaller options available, and is a great way to store your energy.

Tesla Powerwall

In the last breath of 2015, Tesla Energy announced their launch of their Powerwall, a lithium- ion battery offering both residential and commercial opportunities to store energy. This storage system has been met with huge amounts of hype and anticipation and weighing in at approx. 100kg, it is one of the larger energy storage systems around.

Future of Solar Storage Systems in Australia

Australia has some of the best conditions in the world for solar according to the Climate Council (CC, 2015) with plenty of sun, good roofing, and high electricity prices. With the introduction of solar storage systems, consumers are able to solve one of solar’s biggest difficulties and now they can use their energy, even when the sun isn’t out. With a quarter of electricity bills by 2020 expected to be met by solar according to an ABC news reports (ABC, 2016), there seems to be a promising future for solar storage systems.
