Limondale solar farm registered in West Murray

The Australian Energy Market Operator (AEMO) has announced a major step forward in the West Murray Zone after it granted registration to the biggest solar farm in that troubled part of the grid.

Canadian Solar joins the 500 W-plus panel club

The Chinese-Canadian company has unveiled a range of high-power modules which are set to go into mass production by early next year. The series includes a commercial and industrial rooftop-dedicated product offering a reported 405 W.

Self-cleaning PV system with active cooling tech

An international research group has developed a self-cooling PV system featuring a 250 W 60-cell polycrystalline module and a thermal collector attached to the back side of the panel. The cleaning tech is based on a microcontroller programmable integrated circuit, which controls a rotating DC motor.

PV module prices are falling faster than all predictions

New research from Wood Mackenzie shows that overall system costs for installations using mono PERC modules are set to fall by as much as 20% by 2025.

CER reports significant decline in potentially unsafe PV systems

A very small number of PV systems installed on Australian rooftops are considered to be potentially unsafe, the Clean Energy Regulator’s new report finds. Water entering DC isolators is identified as the greatest risk and the most common cause of PV system failures.

Premature inverter failure – 4.2 GW of capacity will be affected this year, says analyst

U.S.-owned business intelligence firm Wood Mackenzie has attempted to evaluate the market opportunities offered by the repowering of solar projects around the world which feature inverters which are 10 years old – as well as those which will expire ahead of time.

Long read: Collaborative digital fixes for the energy transition

Straddling two state borders, the West Murray region in southeastern Australia has become a microcosm of technical challenges that can plague the energy transition. Faced with serious curtailment of solar farms in this electrically remote region, a remarkable inverter-based technical feat may have changed the game.

South Australia’s rooftop solar could be switched off on the way to 100% renewables

Under a new plan to stabilize its grid, the South Australian State Government is providing $10 million to upgrade its voltage management and giving the green light to the Australian Energy Market Operator to stop its rooftop solar from feeding in when needed. The plan also highlights the importance “smart” PV and stronger network interconnection, primarily the new SA-NSW line a.k.a. Project EnergyConnect.

Spherical monocrystalline solar cells with 18.93% efficiency

The spherical 3D cells can reportedly generate around 101% more power than conventional flat solar cells. Measurements have also shown that the spherical cells provide a 10% lower maximum temperature compared to flat cells, while accumulating less dust.

Hanwha Q-Cells wins patent litigation against JinkoSolar, REC Solar and Longi in Germany

The Düsseldorf Regional Court has agreed Chinese rivals of the Korean manufacturer illegally used its patented passivation technology. The judges granted Hanwha Q-Cells an injunction which requires Jinko, REC and Longi to retrieve all modules featuring the patented technology distributed in Germany since late January last year. Hanwha can also opt to have the offending products destroyed.
