Scientists in Korea have built a green hydrogen system prototype that embeds a PV generation unit based on photoanodes made of perosvksite solar cells. The device purportedly achieved a solar-to-hydrogen efficiency of 9.8% for a device with a size of 0.25 cm2, and 8.5% for a system measuring 123.2 cm2.
Chinese solar manufacturer Longi has responded to recent media reports claiming that it might cut 30% of its global workforce.
Japan has allocated 134 MW of PV capacity in its latest procurement exercise. The lowest bid for a 19 MW solar project came in at JPY 0.00/kWh, surprisingly, while other bids ranged from JPY 4.94 ($0.03)/kWh to JPY 6.98/kWh.
The Chinese manufacturer said its new residential storage system is an ideal solution for balcony PV system. The battery features a maximum input power of 1,200 W and a maximum output power of 800 W.
Maharashtra State Electricity Distribution Co. Ltd (MSEDCL) has started accepting bids to provide 1,000 MW/8,000 MWh of grid-connected energy storage capacity from pumped hydro storage throughout India.
Sri Lanka has launched a tender for 165 MW (AC) of ground-mounted solar, accepting applicants to develop solar plants up to 5 MW ins size, connected to one of 20 selected substations across the country. The winners will sign 20-year power purchase agreements (PPAs) with the state-owned Ceylon Electricity Board.
Chinese manufacturer DAH Solar says its new double-glass panels have a power conversion efficiency of 22.65% and a power output of up to 585 W.
The new panel has a white backsheet and a temperature coefficient of -0.34/C. It weighs 4.1 kg per m2 and, according to the manufacturer, supports all types of installation methods, including roof adhesive and removal mechanical mounting.
A team of scientists from China and the United States studied ways to optimize floating photovoltaics for offshore use. It found that the robustness of the systems was influenced by the size and number of platforms, as well as the types of connections between platforms.
The Bangladeshi authorities have approved three 100 MW solar projects, with tariff rates of around $0.10/kWh.
