Jinko and Trina Vietnam manufacturing exports attract new US tariffs
The U.S. Department of Commerce dramatically increased tariffs on imports from Chinese solar producers operating in Vietnam after the agency concluded that China is subsidizing raw materials for its companies to use in their Vietnamese factories.
BYD launches its first integrated home storage system
The Chinese manufacturer said its Battery-Box HVE is now being sold with either a single-phase hybrid inverter or a three-phase device. The system is available in two versions with capacities of 4.29 kWh and 6.45 kWh.
Research shows degradation mechanisms in rear side of TOPCon solar cells
Researchers from UNSW and Longi have found that the silicon nitride layers used in TOPCon cell rear-side are particularly prone to chemical degradation from sodium contaminants. This can lead to significant open-circuit voltage losses and reduce cell efficiency.
Aiko launches 500 W C&I back-contact solar module with 25% efficiency
The Chinese manufacturer launched its new Infinite panel featuring its proprietary all-back contact cell technology. The module measures 1,762 mm x 1,134 mm x 30 mm and has a temperature coefficient of -0.26%/C.
Growatt releases all-in-one 8 kWh balcony storage system
The battery features four MPPTs and can take up to 2,600 W of PV input. It also has an AC nominal output power of 800 W.
Sungrow unveils 5 kWh home battery system
Sungrow’s new residential battery energy storage system features a compact 182 mm design and is capable of handling a maximum charge/discharge current of 50 A.
UNSW study shows heterojunction solar cell sensitivity to soldering flux
University of New South Wales researchers are part of an international team that has assessed the impact of soldering flux on heterojunction solar cells and has found that the composition of this component is key to prevent major cracks and significant peeling.
Longi unveils anti-dust back contact solar module with 24.8% efficiency
Longi has released a back-contact solar module with 24.8% efficiency, featuring a power output of up to 670 W and a temperature coefficient of -0.26% per degree Celsius.
Jolywood releases 595 W bifacial TOPCon solar panel for harsh environments
The Chinese manufacturer said that its new glass-backsheet Windproof module utilises a zinc-aluminum-magnesium surface alloy technology and a high-strength steel substrate. It features a power conversion efficiency of up to 23.03%.
PV manufacturers making move to coated backsheets
Hard-pressed Asian solar manufacturers have switched from multi-layer polymer backsheets to a single layer of polyethylene terephthalate (PET), with a protective coating on both sides of their modules. Backsheet makers confirm these products, known as “CPC,” are now mainstream. There is little evidence to demonstrate that they can withstand 30 years-plus of outdoor use, however.
