Canadian Solar presents all-in-one residential battery inverter solution
The new product is available in four versions with a storage capacity ranging from 9.9 to 19.9 kWh. The battery inverter comes with a 10-year warranty and can reportedly provide steady operation for up to 6,000 charge cycles.
Chinese PV Industry Brief: Trina buys 70,000 MT of polysilicon from South Glass Group
In other news, a Chinese consortium is planning to build a 10 GW heterojunction (HTJ) module factory in Sichuan and Risen Energy is seeking to raise around $1 billion through a private placement of shares to finance its 5 GW HTJ panel production.
Longi achieves 26.12% efficiency for gallium-doped p-type heterojunction solar cell
The result, confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH), was achieved on a heterojunction solar cell based on an M6 wafer.
Jinergy unveils all-black solar module series for rooftop PV
The all-black series includes a monofacial PERC module with an efficiency of up to 20.86% and an n-type heterojunction product with an efficiency of 21.68%. Both products feature all-black integrated design, with black backsheet, black busbar, black frame and black encapsulant material.
New grid-scale LFP battery from Canadian Solar
The company said it plans to quadruple its battery manufacturing capacity by the end of 2023. The 2.8 MWh lithium-ferro phosphate battery will be unveiled at the RE+ conference in California.
Energy Vault to deploy 2 GWh of gravity storage in China
Energy Vault’s EVx storage system is comparable to pumped hydro, using grid-scale renewable energy when supply is abundant to drive motors and raise 30-ton blocks on a six-arm crane tower, rather than water, up to a height. When power needs to be discharged back to the grid, the blocks are lowered, harvesting the kinetic energy.
Perovskite solar module achieves 21.07% efficiency via nanosecond laser tech
Chinese researchers have used inverted perovskite cells with a p-i-n structure to build a perovskite solar module with a reduced heat-affected zone. The panel achieved a power conversion efficiency of 21.07% and a geometric fill factor of 95.5%.
Perovskite quantum dot solar cell with 16.25% efficiency
Chinese researchers have built a perovskite quantum dot solar cell that is reportedly able to reduce trap-assisted charge carrier recombination. The device has an open-circuit voltage of 1.23 V, a short-circuit current density of 17.73 mA cm−2, and a fill factor of 0.745.
Chinese PV Industry Brief: Tongwei secures order for 382,800 MT of polysilicon
Tongwei has secured a long-term polysilicon supply deal with JinkoSolar, while Chint, JA Solar, and JinkoSolar have agreed to supply their products for a 1 GW solar park now under development in the Sichuan province.
Construction begins on world’s second-largest PV project
