How to detect PV system underperformance using only AC-side inverter data
An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.
New single-diode model tackles recombination losses in solar cells
UNSW researchers have developed an intrinsic-adjusted single-diode model that explicitly accounts for radiative and Auger recombination, improving I–V curve accuracy and reducing root mean square error by up to a factor of three. The model is claimed to better predict performance near open-circuit voltage and maximum power point.
Investment rally coincides with renewables records in Australia’s NEM
A record five large-scale renewable energy generation projects totaling 1.2 GW reached financial close across Australia’s National Electricity Market (NEM) in the last quarter, but industry figures say more needs to be done to ensure investment momentum continues.
Hallett battery project reaches financial close in Australia
EnergyAustralia’s 50 MW/245 MWh Stage 1 Hallett battery energy storage system (BESS), co-located with a gas-fired power station, has reached financial close and is moving into the delivery phase.
New algorithm reduces solar module temperature during clipping, curtailment
UNSW researchers have developed a thermal-aware tracking algorithm that reduces solar module temperatures and UV exposure during inverter clipping and curtailment, slowing degradation without lowering AC output. Tested in Chile’s Atacama Desert, the strategy was found to lower module temperatures by up to 7.7 C.
Hot, dry start to 2026 lifts Australian PV, despite fires and monsoon losses
In a new weekly update for pv magazine, Solcast, a DNV company, reports that most of Australia experienced above-average solar irradiance in January 2026 due to a hot, dry airmass and clear skies, boosting PV generation despite operational challenges from elevated temperatures, bushfire smoke, and dust. In contrast, northern Queensland and far northern regions saw significant irradiance deficits from persistent monsoonal clouds and Tropical Cyclone Koji, causing widespread rainfall and localized power outages.
Australia grid constraints push data centers to regions
Grid capacity constraints in major Australian metropolitan hubs are prompting data center developers to consider regional locations with integrated on-site gas and solar generation, according to renewable energy land brokerage Rok Solid.
New reflective coating increases BIPV power output by 11%
Australian researchers developed a low-cost reflective coating for semi-transparent solar roof tiles that lowers surface temperatures by up to 20 C and boosts power output by up to 11.7%. Simulations across five global cities showed energy savings of up to 5.85%, highlighting the coating’s strong potential for improving both building cooling efficiency and solar performance in BIPV systems.
Australian state awards 12 GWh of long-duration storage contracts
New South Wales has awarded long-term energy service agreements to six battery energy storage projects totaling 1.17 GW and nearly 12 GWh, lifting the state’s contracted storage capacity to 30 GWh.
Australia rooftop solar volumes fall 32% after four-month rebound
Rooftop solar installations in Australia declined sharply in January, with small-scale technology certificate (STC) volumes down 32% month on month after four consecutive months of growth, according to market analyst SunWiz. It says the result was broadly in line with seasonal norms and does not signal a trend for 2026.
