Battery companies hoping to get a foothold in Australia’s rapidly growing storage market were the main exhibitors at the Smart Energy Conference held in Sydney last week, outnumbering solar companies almost two-to-one. Pv magazine Australia looked at what is on offer and who the new hopefuls in the battery space are.

While Australia’s home battery market seems to have attracted most of the interest from newcomers, there has been some significant new developments in the commercial and utility-scale space. Pv magazine Australia examined the new products and companies in the commercial and utility battery storage space on display at the Smart Energy Conference.

An international research group led by Longi Central R&D Institute has published a paper describing Longi’s heterojunction solar cell based on a full-size silicon wafer that made a sensation in November, as it beat the long-lasting efficiency record held by Japanese manufacturer Kaneka for years. The researchers attributed the cell efficiency improvement to the implementation of a p-type amorphous silicon hydrogenated layer together with a modified transparent conductive oxides contact, which they said greatly reduced the cell contact resistivity.

JinkoSolar, Long, JA Solar, and Trina Solar have all reported impressive growth figures for the first quarter of this year.

Zhengrong Shi and his company, Suntech, are true pioneers of the Chinese solar industry. While Suntech burned bright, and eventually flamed out, under Shi’s leadership, the company’s solar ecosystem and innovation persist as China’s PV market surges past 100 GW(AC) today.

China reached 327.4 GW cumulative installed PV capacity at the end of February, according to new figures from the National Energy Administration (NEA).

Chinese battery industry heavyweight CATL has unveiled a novel condensed matter battery technology with an energy density of up to 500 Wh/kg. The company said it can achieve mass production within this year.

China’s Bslbatt has added a rack-mounted battery to its ultra-sim range. It has a storage capacity of 5.12 kWh and a nominal voltage of 51.2 V. It measures 670 mm x 475 mm and is 89 mm thick.

Trina Solar’s tracker subsidiary has launched a new version of its Vanguard single-axis two-in-portrait (2P) tracker. It uses multiple motors on one tracker row, reportedly allowing it to withstand higher wind loads and reduce tilt angle misalignment. The new solution is compatible with large modules up to 685 W.

TrendForce has ranked the top six module manufacturers by shipment volume in 2022, with Longi topping the list, followed by Trina Solar and JinkoSolar. JA Solar, Canadian Solar, and Risen Energy rounded out the top six, in a year dominated by large-format modules.
