President Xi Jinping’s pledge this week at the United Nations General Assembly that China will not build new coal-fired plants abroad is welcome news; however, Asia’s transition to low carbon energies remains in dire need of policy reforms.

With pressure mounting on the world’s governments to turn their back on the fossil fuel, China and peers in South East Asia, Europe and South Asia could help deliver a coal-free future at the COP26 climate summit planned in Glasgow in November.

Polysilicon capacity is unable to catch up with rapid capacity expansion in the mid and downstream segments, writes Corrine Lin, chief analyst for PV InfoLink. New polysilicon capacity requires big capex investment and a lead time of more than two years to complete construction and reach full operation. With unbalanced capacity between the upstream and downstream segments, polysilicon prices have been rising since the second half of 2020, with prices for mono-grade polysilicon surpassing CNY 200/kg (US$27.40) in June 2021, up more than 250% year on year.

Researchers in China have analysed how the marine environment influences the performance of PV modules deployed on ships, and have found that salt particles can be detrimental to their performance as these act as both heating agents and a factor reducing solar irradiance. The temporary cooling effect provided by seawater is not sufficient to offset the impacts of salt spray and ensure increased power yields.

The storage project is linked to a 1 GW wind and solar project portfolio, 500 MW of solar distributed generation, and the construction of a gigafactory for vanadium redox flow batteries in China.

The 3 kW inverter has an efficiency of 95% and features a surge power of 9000 VA. According to the manufacturer, the device is compatible with mainstream lead-acid and lithium-ion batteries.

Solar product detentions at U.S. ports of entry all stem from a June 24 “Withhold Release Order” issued by Customs and Border Protection.

China’s efforts to shift electricity generation from a coal-dominated system to a greener mix of renewables is not only centred on wind, solar and other technologies – the country is also rapidly pursuing energy storage. Vincent Shaw reports from Shanghai.

The new factory should begin production within six months and serve the company’s cell and module assembly factories in Malaysia, as well as the module assembly facility in the United States.

Researchers in China have developed a smart solar window tech based on a photovoltachromic device that is able to achieve a high pristine transmittance and to be self-adaptable to control indoor brightness and temperature. The device was assembled via a full solution process in an architecture incorporating glass, a fluorine-doped tin oxide (FTO) layer, a perovskite-based PV cell, an electrochromic gel, another FTO layer, and glass.
