Australian manufacturer reveals 1 MWh sodium chloride battery design
Altech Batteries, a battery tech company in Western Australia, has included “game-changing” sodium chloride technology in its new battery 1 MWh GridPack. It said it expects the new systems to be up to 40% cheaper to produce than dominant lithium-ion alternatives.
Case study demonstrates 5% energy yield boost for n-type TOPCon modules
Data collected from a 30 MW PV project in China’s Tianjin Province demonstrates that n-type tunnel oxide passivated contact (TOPCon) modules achieve a little more than 5% more energy yield than p-type PERC. Analysis by JinkoSolar, which supplied its TOPCon modules to the project, credits the n-type modules’ increased performance to a better temperature coefficient in the project’s hot climate, higher bifaciality and lower degradation.
Sterling and Wilson Renewable Energy selects Nextracker for NTPC’s 1.568 GWp solar plant
Nextracker will supply its optimized bifacial solar trackers for NTPC Renewable Energy’s 1.568 GWp PV project in the Indian state of Gujarat. The project, India’s largest contiguous solar power plant, is being implemented by Sterling and Wilson Renewable Energy.
Silicon anode lithium-ion battery cell with 500 Wh/kg density
Amprius has obtained third-party performance verification for a battery cell that offers high power density in a lightweight package.
German manufacturer achieves 80% overall efficiency with new PVT solar module
Sunmaxx says Fraunhofer ISE has confirmed the 80% efficiency of its new photovoltaic-thermal (PVT) module. It consists of 108 PERC half-cells in M10 format, with 400 W of electrical output and 1,200 W of thermal output.
Indian researchers develop low-cost method to produce metal-oxide layers for solar cells
Researchers at IIT Mandi developed high-quality, uniform thin films of nickel oxide on the silicon substrate using an aerosol-assisted chemical vapor deposition technique with nickel nitrate as the precursor material.
Shingle all the way
While shingled cells have been around for a while, Tongwei’s adoption of the technology is notable as it is a manufacturer with considerable scale. If shingling can overcome some hurdles, it could prove a welcome solution as unshaded sites for PV become elusive in mature solar markets.
L&T signs electrolyzer manufacturing agreement with McPhy Energy
Larsen & Toubro (L&T) has signed the agreement to manufacture pressurized alkaline electrolyzers in India under a technology license from France-based McPhy Energy.
Ircon Renewable Power seeks bifacial modules for 600 MW DC solar project in Karnataka
Ircon Renewable Power has tendered the manufacturing and supply of 530 Wp+ mono PERC bifacial modules under the domestic content requirement of a 600 MWp solar PV project at Pavagada.
