Scientists in Japan have developed a model that predicts surplus solar generation and creates a route for optimised charging of electric delivery vehicles, defining their work as a practical blueprint for logistics operators.

A partnership between PXP Inc and Tokyo Gas Co is working on developing film-type chalcopyrite solar cells for industrial roofs with low load-bearing capacity. Elsewhere, a coalition of partners is installing inner windows featuring perovskite solar cells at Tokyo’s Telecom Center Building.

Eku Energy, jointly owned by Australian financial services group Macquarie, has seen it’s Japanese subsidiary successfully bid for a long-term power source auction two months after a similar long-term energy services agreement was awarded in Australia for its Griffith BESS.

Queensland-based electric vehicle charging infrastructure provider EVOS has stepped up expansion plans after reaching agreement with Japanese manufacturer FKK to produce its chargers for sale in Japan, Southeast Asia and other high-growth markets including India.

Sumitomo Electric’s new system comes in three versions, providing up to 10 hours of storage. It achieves improvements in output and energy density, through component enhancements, thereby reducing cost and physical footprint.

JinkoSolar has sued Longi for patent infringement in Australia, its third legal action against the company this year, following filings in China and Japan. The lawsuit, filed in the Federal Court of Australia, claims that Longi used an unspecified solar cell technology.

JinkoSolar’s latest n-type tunnel oxide passivated contact (TOPCon) modules delivered higher energy yield per watt than a competitor’s n-type back contact (BC) modules in a three-month field test in Japan, under varying irradiance levels.

Scientists have proposed a building-integrated PV system that integrates airflow to cool the panels and control room temperature. The system, which also acts as a shading device, can reportedly mitigate drops in power generation efficiency without additional energy consumption.

With electric vehicle demand continuing to grow in Australia, Japanese auto manufacturer Toyota has revealed it will team with mining giant BHP to trial the “first ever” battery-powered HiLux dual-cab ute.

The latest irradiance sensor solution from Japan-based EKO Instruments provides continuous measurements in the field. Well-suited for bifacial PV systems, it supports the measurement of global horizontal irradiance, diffuse horizontal irradiance and direct normal irradiance, even in reflective and cloudy conditions.
