Yingli’s 156-cell Panda 3.0 PRO module has a temperature coefficient of -0.30% per degree Celsius and is available in wattages ranging from 590 W to 615 W, with a bifaciality of more than 90%.

A team of Australian researchers have developed a way to use rooftop solar PV to run air conditioners to pre-cool residential and commercial buildings. They have identified several factors that could help reduce a building’s energy costs.

Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.

Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.

Israeli researchers have developed a device that combines a reversible Si anode with halide cathodes and uses hybrid electrolytes to enable cell recharging. In the proposed system configuration, silicon is dissolved during the battery discharge process, and upon charging, elemental silicon is deposited.

The system is reportedly able to refill about eight hydrogen fuel cell vehicles, each in three minutes. It is also able to supply electric power by using hydrogen produced with renewable energy within the station.

Chinese manufacturer Bslbatt has unveiled an upgraded version of its residential battery. The device has a storage capacity ranging from 5.12 to 12.8 kWh and is reportedly able to provide steady operation for up to 6,000 charge cycles.

The novel technique consists of attaching cotton wicks immersed in the water (CWIWs) to the backside photovoltaic module. The water is supplied to cotton wicks from top to bottom by gravity which the scientists said helps the effective absorption of cotton and reduces water consumption.

New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.

The panel has an absorption area of 1.96 m2 and a weight of 27 kg per square metre. According to the manufacturer – Swiss start-up TVP Solar – it may be a real booster for thermal output, by combining it with photovoltaics and heat pumps to provide enhanced output per square meter, in particular for low-temperature applications such as district heating.
