Scientists classify weather types based on extreme photovoltaic output events
Scientists used a year’s worth of data from East China to analyze what weather conditions affect abnormal, high, and low PV output days. They also constructed a simple extreme output prediction model and examined the atmospheric circulation anomalies corresponding to extreme output events.
SolaX releases new 215 kWh storage system
SolaX has released a new 215 kWh storage system featuring 280 Ah lithium iron phosphate (LFP) battery cells, with 100 kW of rated AC power and a maximum efficiency of 98%.
Bslbatt launches storage system for C&I applications
Bslbatt says it has developed a new storage system for commercial and industrial applications, offering up to 241 kWh of capacity and supporting 100 kW or 125 kW of solar.
Dyness launches new C&I battery
Dyness has developed a new small-scale storage system in 71 kWh, 86 kWh, and 100 kWh variants for commercial and industrial (C&I) applications. The Chinese manufacturer says the product is based on lithium iron phosphate (LFP) cells.
Radiative cooling tech based on polydimethylsiloxane film increases PV module generation by up to 3.72%
Scientists in China have proposed to use polydimethylsiloxane films doped with soda glass to reduce solar module temperature. The coating achieved solar transmittance of 94.8% and sky window emissivity of 95.3%.
Dual-axis solar tracker based on UV, MEMS sensors
Researchers have designed a new tracking system that utilizes an arithmetic optimization-based PID controller. The proposed tracker uses two different sensor types – a UV sensor and a micro-electromechanical solar (MEMS) sensor. The first one calculates the intensity of UV radiation received from the sun, and the second one forecasts the sun’s path across the sky.
JA Solar sues rival module manufacturer over TOPCon patent infringement
The Shanghai-based solar development company has filed two complaints with the Munich and Hamburg local divisions of the Unified Patent Court.
Hydronic closed-loop cooling system for photovoltaic modules
An international research team has developed a closed-loop PV cooling system that can reportedly offer 24-hour continuous operation. The system is claimed to be particularly suitable for hot and arid regions and to improve the lifespan of solar panels by up to 8.2%.
Weiheng Ecactus releases three-phase all-in-one battery storage system
The Chinese manufacturer’s new battery energy storage system consists of an inverter ranging in size from 5 kW to 13 kW and a storage system of 10 kWh to 30 kWh. Up to five units can be connected in parallel.
Chinese PV Industry Brief: Akcome provides update on restructuring process
The Chinese cell maker said its unit Zhejiang Akcome Photovoltaic Technology has received the green light for restructuring. However, if the reorganization is unsuccessful, the company will proceed to bankruptcy liquidation.
