GoodWe has developed a 60 kWh battery for commercial and industrial PV systems, featuring a compartment for its ET15-30kW inverter series.

Trina Storage has developed a 4.07 MWh energy storage system featuring its in-house 306 Ah lithium iron phosphate battery cells, configured with 10 racks of four battery packs.

Researchers from China and the UK have improved the Adam optimization algorithm to achieve better results in dust detection on PV panels. The optimized algorithm reportedly performed better than most common algorithms used for dust detection.

Scientists from China have developed a novel optimization method for medium-depth ground source heat pumps, using an improved chaos particle swarm optimization. They coupled it with either a heat storage tank or a shallow borehole heat exchanger and found that both system typologies increase the heat pump’s coefficient of performance.

Chinese inverter manufacturer Deye has developed a new all-in-one energy storage system (ESS) with 50 kW of output and 61.4 kWh of storage capacity. It features LiFePO4 batteries with a maximum temperature of less than 40 C.

Chinese manufacturer TSUN says its Titan series of microinverters can handle 15 A of continuous input DC current. They also feature a 97.2% efficiency and four maximum power point tracking (MPPT) channels.

China’s SolaX Power has developed two lines of integrated energy storage systems that reportedly support up to 200% PV oversizing. Their rated output power ranges from 3 kW to 15 kW.

Scientists in China have used computer simulations to gain a better understanding of the factors that influence the adoption of residential PV.

Researchers in China have developed a novel way to predict the cloud coverage of PV plants. The method uses geostationary satellite and recurrent-neural networks.

Hoshine says it will build a solar glass factory in Urumqi, the capital of China’s Xinjiang region, where it is also planning a 20 GW vertically integrated module manufacturing facility.
