Quality

Extreme weather is a growing risk to solar farms. Future-proofing through advanced technologies, leveraging data from novel sources, and by building both collaboration and acceptance of risk is vital, but rarely achieved today for a number of reasons. Insurers, lenders, developers, contractors and manufacturers come together here to discuss solutions to the intractable problem of weather risk.

Around 6,000 batteries involved in the years-long LG battery recall have not yet been located, the ACCC has said. To date, there have been at least nine reported incidents involving the batteries, including one personal injury and one house “completely destroyed.”

Taking a rigorous approach to inspection is crucial across the energy storage supply chain. Chi Zhang and George Touloupas, of Clean Energy Associates, explore common manufacturing defects in battery energy storage systems (BESS) and how quality-assurance regimes can detect them.

It is time to call out the problems of Net Zero, Enosi’s Grant McDowell argues. To reach a fully renewable grid, companies and institutions instead must embrace what he calls True Zero.

A new study from Clean Energy Associates (CEA) shows that 83% of sites tested as part of a global survey had line cracks, 78% had a soldering anomaly and 76% had complex cracks. The survey involved visual inspections combined with electroluminescence testing across 148 sites in 16 countries.

Renewable energy investor and developer Quinbrook has launched software to allow customers to trace both the source and carbon-intensity of their electricity in real-time. The energy-tracing platform comes at an important moment, just as Australia’s government is deciding whether to include time-stamped and granular source information in its formal certificate schemes.

Scientists in Spain tested PV modules under partial shading conditions, aiming to better understand the formation of performance-damaging hotspots. The study reveals a potential issue particularly affecting half-cell and bifacial modules, which may cause accelerated performance loss and is not covered by current testing/certification standards.

The company supplying the technology for what has been branded Australia’s “biggest battery” has cautioned that manufacturers must ramp up their focus on hardware, increase investment in advanced software and improve testing practices to minimise the risk of lithium-ion batteries catching fire.

South Korean electronics manufacturer LG has updated the recall of its solar batteries with Australia’s consumer watchdog warning owners of LG-branded batteries to “immediately” switch off their solar storage systems amid concerns the battery may overheat and ignite.

pv magazine has learned that five solar-related fires in Germany and Austria occurred in late September. Photographs show that two of the blazes were likely caused by residential batteries manufactured by LG.
