In a new weekly update for pv magazine, OPIS, a Dow Jones company, reports that pessimism in the global polysilicon market has deepened, driven by a persistent oversupply that exceeds buyers’ total monthly purchasing volumes. Several global polysilicon buyers have confirmed maintaining substantial inventories, which has contributed to the current subdued trading activity.

US-based software provider Solesca presents new ways of handling PV system unavailability and solar module degradation. Engineers have a key role to play in this evolution, ensuring more accurate and reliable energy predictions for solar projects.

Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.

Scientists have placed mist nozzles inside a bifacial PV module and measured it under an extremely hot climate. The module was found to generate up to 37% more electricity on sunny days and up to 46% more on cloudy days compared to standard monofacial panels.

Engineers at Monash University have a developed a next-generation water-based battery suitable for application in residential use and compatible with rooftop solar in real time.

pv magazine is compiling a guide to home solar installations, aimed at those who are interested in installing but are new to the market and want to make an informed decision. We have spoken to associations, installers and industry specialists in major solar markets across the globe to compile best practice guidance and advice that aims to be applicable to home solar installations anywhere in the world.

Researchers in Sweden and Italy analyzed the economics of one-axis, vertical, and elevated PV systems for agrivoltaic applications, finding that overhead agrivoltaic systems may perform better the further south they are installed. The discounted payback period and levelized cost of electricity were also calculated and compared.

Biwatt has unveiled a 155 kWh sodium-ion battery energy storage system (BESS) for commercial and industrial (C&I) customers.

Nuberg EPC and EDL Anlagenbau Gesellschaft mbH (a Poerner Group company) have signed a technical collaboration agreement (TCA) for the development of green hydrogen and derivatives such as green ammonia, green methanol and sustainable aviation fuels.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
