Inverter sizing guides grid connection, rules US court

The US Court of Appeals has ruled that an 80 MW (AC)/160 MW (DC) solar farm, with 50 MW of battery storage, meets “Qualifying Facility” status of 80 MW (AC) or less under the Public Utility Regulatory Policies Act (PURPA) of 1978.

Only5min! – Spanish solar manufacturing

On the first day of Spain’s Genera tradeshow, pv magazine spoke with Joan Groizard Payeras, Managing Director of Spain’s IDEA (Instituto para la Diversificación y el Ahorro de la Energía) about the current state of solar manufacturing in Spain, and what the government is doing to the make its domestic industry more competitive.

German machinery unlocks onsite transmission line recycling in Australia

Australian grid operator Transgrid has partnered with German machinery manufacturer Zeck for the use of its innovative steel separation tech. Zeck’s machine can process electricity transmission lines into a recycle-ready state onsite. Previously, Transgrid sent old transmission lines offshore for this process at a much higher cost.

Seawater heat pump pilot project in Croatian shipyard

Croatia’s Viktor Lenac Shipyard aims to replace electric boilers and a water-to-water heat pump with a seawater heat pump, in order to provide heat and cooling for buildings. The pilot project is backed by EU funding and has launched a tender to support the construction of the seawater heat pump.

Photovoltaic electolyzer with shingled solar panels, anion exchange membrane

Scientists in Belgium have designed a solar-powered electrolyzer that uses standard-sized, large area shingled silicon PV for water splitting. The system is reportedly able to achieve solar-to-hydrogen efficiency of 10% at electrolyzer current densities of approximately 60 mA cm−2.
