Acciona Energia is setting up its first V2G network in Spain, ADS-TEC has unveiled a battery-based, all-in-one system with up to 300 kW of charging power, and Volkswagen is looking for a location for its first battery cell factory in North America.

Japanese researchers claim that tin sulfide solar cells could achieve higher open-circuit voltages by preventing “Fermi level pinning” from occurring, due to the addition of a tin sulfide interface with large band bending.

While solar modules and inverters can greatly influence the output of a planned solar project, it is important not to overlook how to select and design cabling systems for your solar plant – for safety as well as generation considerations. Ye Qilin, a senior system engineer at Huawei’s FusionSolar smart PV and energy storage business, runs us through some dos and don’ts.

Th International Energy Agency (IEA) says unsubsidized heat pumps are already competitive with gas boilers in mature markets like the United States, Canada, Japan, Italy, and China. It says global sales will soar to record levels by 2030.

Japan’s Itochu has announced a new tie-up with France’s Rosi Solar, which develops tech to recover and recycle high-purity silver, copper and silicon from solar modules.

Ibis Power has developed a rooftop system that combines solar with wind turbines designed for medium-sized structures and high-rise buildings. It claims its PowerNEST system can produce six to 10 times more energy than standalone rooftop solar. The company has already installed five projects in the Netherlands.

Mitsubishi has released a cascaded air source heat pump that can produce between 7.8 kW and 640 kW of heat. It is reportedly able to generate hot water at a temperature of up to 70 C without boost heaters.

Kaco has launched a new line of blueplanet NX3 three-phase string inverters for applications ranging from small residential rooftop arrays to projects on commercial buildings. They have outputs between 3 kW and 33 kW, a maximum efficiency of 98.0%, and a maximum European efficiency of 97.6%.

Chinese scientists have made mono cast silicon ingots with high purity and low manufacturing costs. The new method will help industrial casting manufacturers to improve the cost performance of casting ingots.

South Korea’s SK is developing battery chargers with integrated battery diagnosis, Australian battery specialist Xelectric Power and Germany’s Mobilespace have launched a truck-mounted battery, and BMW Group has revealed plans to build assembly lines for high-voltage batteries next to its new vehicle plant in Hungary.
