Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export limits, distribution static synchronous compensators, the replacement of old conductors in power grids, load reconfiguration, and dynamic voltage restoration.

Bids are invited from Indian manufacturers to supply 72-cell, 325Wp polycrystalline solar modules made using domestically manufactured cells. August 20 is the last date to lodge the interest.

The software giant has begun testing hydrogen fuel cells as a back-up power source at one of its U.S. data centers. A 250 kW pilot system successfully powered part of the facility for 48 hours and the company is now eyeing 3 MW systems to replace back-up diesel generators.

State-owned Power Finance Corporation will provide Rs 2.38-crore financial assistance to the Indian Institute of Technology-Kanpur to develop infrastructure for R & D in smart grid technology.

Scientists in the U.S. claim to have demonstrated an inexpensive, long-life, safe and eco-friendly redox flow battery. The device is said to offer coulombic efficiency of 97.9%, thanks to functional electrolyte additives, pH and elevated temperature.

India’s Ministry of New and Renewable Energy had invited consulting proposals for its ambitious globally interconnected power grid plan called ‘one sun, one world, one grid’ (OSOWOG). The program—taken up with assistance from the World Bank— aims at seamless sharing of renewable energy resources among countries for mutual benefits and global sustainability.

To support renewable energy integration, the government aims to make the thermal capacity flexible, almost 55% in the first stage and gradually extend it to the entire capacity.

The system can metallize the front and back sides of silicon solar cells with unprecedented precision and speed, Fraunhofer ISE said. The technology is also suitable for components such as printed circuit boards or chip cards.

Floating PV specialist Ocean Sun and South Korean energy company EN Technologies have signed an agreement to develop the pilot projects of the 2.1 GW floating solar site planned near the Saemangeum tidal flat, on the coast of the Yellow Sea.

The containerised solution integrates grid connection and multiple charging systems, allowing public transport and commercial fleet operators to charge more electric vehicles with less infrastructure in depots.
