Saturday read: In conversation with UNSW’s Anna Bruce on distributed transformation

The time is now for the energy consumer, says Anna Bruce, as energy “prosumers” produce, consume, and provide electricity and grid services in previously unimagined ways. Bruce, a senior lecturer at the University of New South Wales’ School of Solar Photovoltaic and Renewable Energy Engineering (SPREE), leads work on the role of distributed energy resources in the energy transition, analysing firsthand the dizzying level of complexity it brings.

Solar manufacturers warn of 12-18 months disruption for standalone products

Potential price rises of 14% for the solar home systems that are driving access to electricity in the world’s under-served regions could signal further arrested progress towards the UN goal of universal access by 2030.

Saturday read: the more you know

Module-level power electronics, most often in the form of power optimisers and microinverters, offer a range of value propositions, including advanced monitoring capabilities. But how much can the little box behind the module really see, and how much do operators actually need to know to keep a power plant running optimally?
