The Serbian government has allocated a quota of 50 MW for its first solar auction. Solar plants with capacity of more than 500 kW will be allowed to participate in the competitive tendering process, with the ceiling price set at €90 ($96.10)/MWh.

SolarEdge’s new software-based solution manages and optimizes the electric-vehicle (EV) charging process for sites that have solar resources and large numbers of EVs requiring dynamic load management.

Researchers in Morocco have carried out an experimental investigation which has confirmed that even in hot desert climates, the wind has a positive effect on reducing the PV module temperature, improving the electrical production as well as the conversion efficiency.

US-based Salgenx says it has successfully integrated ultracapacitors with its saltwater redox flow batteries, resulting in significantly better power response and system performance.

NGK Insulators has switched on 1 MW/5.8 MWh of NAS batteries under a demonstration project to assess the performance of stationary storage at a site operated by Korea Electric Power Corp. (KEPCO).

Hong Kong Polytechnic University researchers have developed a binary organic solar cell (OSC) with a record power conversion efficiency of 19.31%. They invented a non-monotonic intermediate state manipulation strategy to lower the non-radiative recombination loss and boost efficiency.

Hungary, one of Europe’s gigawatt-scale solar markets, is a hub of bustling activity. However, government policy shifts and grid constraints are casting a long shadow over growing demand for solar energy. pv magazine recently spoke with Ádám Szolnoki, the president of the Hungarian Photovoltaic Industry Association (MANAP), about the latest market developments.

Power purchase agreements (PPAs) are growing in popularity in Poland due to high energy prices and the declining appeal of renewable energy auctions. Nevertheless, regulatory changes have created uncertainty and reduced attractiveness.

Researchers at Tohoku University in Japan have developed a prototype calcium battery with a long cycle life of more than 500 charge-discharge cycles. The battery was developed using a hydride-based electrolyte and copper sulfide nanoparticle/carbon composite cathode.

Brisbane-based Li-S Energy has developed a 20-layer battery cell utilizing semi-solid state lithium sulfur battery technology. The company claims the new cell displays nearly double the gravimetric energy density and a comparable volumetric energy density to lithium-ion cells.
