With rooftop solar surging, smart power electronics will be required to secure system strength and ensure that new limitations on rooftop PV don’t put a break on growth. Italy-based power electronics supplier FIMER believes its new range of string inverters are well equipped to do just that, as explains Fimer Australia and New Zealand’s Jason Venning and Warren Merritt.

The South Korean manufacturer has brought, to Europe and Australia, its recently launched shingled PERC panel, with an output ranging from 460 to 480 W and an efficiency of up to 20.5%. The products come with a 25-year linear power output guarantee and a 25-year product guarantee.

Smart metering services provider Intellihub has outlined a series of targeted reforms – including strengthening testing requirements – in its submission to the Australian Energy Market Commission’s (AEMC) review into the sector’s regulatory framework, cautioning that unless changes are made Australia risks being left behind.

South Australia is leading the nation in terms of renewable energy penetration, with rooftop solar a major contributor. But the state’s hard-won ability to deactivate thousands of rooftop solar systems in response to grid voltage disturbances has caused significant disruptions to solar installers. With a deeper look inside the changes, it appears to be a good thing for solar in the state, as well as other markets in which distributed PV is growing rapidly.

Long-standing solar PV manufacturer Suntech is set to expand its offerings in the Australian market with the imminent release of sister company Sunways’ range of single-phase inverters.

The tide of clean energy facilities planned under the city’s next five-year strategy was revealed by Hong Kong-listed polysilicon maker Xinte Energy, which has signed a framework agreement to construct 200,000 tons of manufacturing capacity near Inner Mongolia’s largest city.

Energy consultancy DNV GL has published new results comparing the performance of modules based on 166mm, 182mm and 210mm silicon cells. The assessment compares Trina Solar’s Vertex modules, which use the largest cell dimension, with unnamed competitors utilising the other two sizes. Results from system simulations show a clear advantage for the two larger sizes, with 210mm edging ahead in terms of levelised cost of electricity.

The incremental improvements achieved each year in solar are usually relatively small, and improvements to one component can easily be accommodated by the rest of the system. But every so often, a bigger change comes along, with implications that will ripple up and down the supply chain.

Chinese solar inverter giant Sungrow has taken the first step towards increasing its Australian market share in 2021 with the launch of its second generation three-phase residential inverters.

The Australian arm of South Korean solar technology giant Hanwha Q-Cells has extended its reach, launching into the New Zealand energy market.
