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.

India’s solar module makers have built a strong track record, and now the country is set to see vast battery facilities developed. Uma Gupta provides a look into ambitious manufacturing projects and the wider enabled ecosystem.

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.

Scientists in the U.S. discovered a promising new battery chemistry based on chlorine and table salt. Batteries based on this chemistry can achieve at least six times the energy density of today’s lithium-ion batteries, according to the group that created it. The prototype battery could already be suitable for small devices such as hearing aids, and with further work could be scaled up to larger applications.

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.

The state-run energy company has commissioned a 25 MW plant on the reservoir at its Simhadri thermal power station, in the state of Andhra Pradesh. The installation features more than 100,000 solar modules.

Developed by the Korea Institute of Energy Research (KIER), the “non-destructive” technology is claimed to enable the recovery of 100% of a module’s glass and to allow the reuse of silicon for producing new solar cells with an efficiency of 20.05%.

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.

Next Energy and Marubeni are developing a blockchain tech for PV module inspection – with the support of the Japanese government – which they claim is able to provide data on a panel’s traceability and components as well as verifying that the data were not modified or tampered with.
