The Salt River Project has announced a 250 MW, 1,000 MWh battery project in Little Rainbow Valley, Arizona. The installation will be the largest in the state and among the largest in the United States.

With the Q Cells solar business warning it is preparing an instant appeal if a U.S. ITC judge rules against it Stateside, the chemical company parent announced its solar panel business saw a year-on-year, third quarter rise in revenue from KRW818 billion to KRW1,638 billion.

The state’s 2019 Integrated Resource Plan foresees just over 11 GW of solar power generation capacity and at least 11 GW – with a possibility of up to 19 GW – of energy storage necessary to meet resource adequacy as part of the state’s legally required 60% renewable portfolio standard by 2030. Prices have halved since 2017.

Korean PV manufacturer Hanwha has accused competitors in the U.S., Germany and Australia of having infringed its patents. In America, Jinko Solar – as well REC and Longi Solar – applied for an interim review of a patent at the International Trade Commission. Now, Jinko says it expects the judges to rule in its favor.

The Chinese-Canadian manufacturer reported a 1% decrease in sales in the third quarter, with net profit falling 19%, to US$55.2 million. Quarterly shipments were up significantly year on year, from 1.59 GW in July-to-September last year to 2,387 MW this time around. The company expects to ship up to 8.5 GW of panels and achieve turnover of up to US$3.16 billion this year.

Researchers at Sweden’s Lund University have discovered a mechanism by which iron-based solar cells lose up to 30% of their charge. Understanding how the loss occurs, say the researchers, will be the first step to closing the loophole and developing more efficient solar cells based on the abundant material.

A U.S. research group has developed a metal-carbon-nanotube composite – MetZilla – which can be embedded in commercial, screen-printable silver pastes and is said to reduce the formation of hotspots in solar modules and to prolong panel lifespan. The composite metal contacts are also ‘self-healing’ as they are able to regain electrical continuity after cycles of complete electrical failure caused by extreme strain.

The U.S. company’s transformation from solar manufacturer to the second-largest residential PV company in the nation is complete after it spun off its high-efficiency cell and module production unit into a new entity, in partnership with Chinese wafer maker TZS.

The California-based Hanergy subsidiary has broken its efficiency record for a large area, flexible CIGS module, achieving 18.64% on a device with a 1.08m² aperture. The record has been confirmed by Germany’s Fraunhofer Institute for Solar Energy Systems.

Scientists at Rice University in the United States have found by strategically adding indium to an all-inorganic, lead-based perovskite, they can reduce the number of defects in the material and improve its efficiency, as well as providing a significant boost to stability.
