New battery for residential, commercial applications
Dutch manufacturer MG Energy Systems is offering a new storage system in two versions, with capacities of 5.8 kWh and 7.2 kWh and nominal capacities of 230 Ah and 280 Ah.
PV with gravity storage, redox flow batteries in buildings
Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.
Bhutan issues tender for 17.3 MW solar park
Bhutan aims to facilitate the construction of its first PV project through a new tender.
World’s largest underground hydrogen storage project
Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.
Photovoltaic micro-inverter based on gallium nitride transistors
Scientists from France’s CEA-Ines developed a 400 W micro-inverter with a power density of 1.1 kW/L and an efficiency of 97%. The device utilizes GaN 600V diodes and power transistors developed by CEA’s electronic branch CEA-Leti.
Using p-type wafers in heterojunction solar cells, not a lost battle
An international research group has reconstructed the trajectory of p-type wafers in the heterojunction solar cell segment and has identified the lack of knowledge about boron-oxygen related light-induced degradation (BO-LID) as the main cause for the limited adoption of these wafers and the success of their n-type counterparts. According to the scientists, however, there is still big room for improvement for p-type technologies in heterojunction cells.
The PV industry needs 12 times more polysilicon production capacity by 2050
New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.
