Researchers from the Solar Energy Research Institute of Singapore have concluded that utility-scale PV projects relying on bifacial panels and single-axis trackers deliver the lowest levelized cost of energy in most of the world. They found that the combination of bifacial products with dual-axis trackers is still too expensive, despite the higher yield. The second-lowest LCOE is offered by monofacial single-axis tracker plants.

The new Indo-Danish cooperation will prepare the Indian energy system for the integration of 450 GW renewable energy by 2030. It will focus on knowledge exchange in areas such as energy planning and scenario modelling, integration of high share of renewable energy, power system flexibility and electricity markets.

The Kolkata-based manufacturer’s Somera monocrystalline silicon and Eldora polycrystalline silicon PV modules met and exceeded international quality and performance benchmarks in assessments by PV Evolution Labs.

October 31 is the last date to submit proposals for developing economically viable energy storage solutions that can be integrated with appropriate renewable energy sources to provide an uninterrupted power supply for rural households and enterprises.

Scientists in Japan have proposed a new model to estimate cell voltages in solar modules by irradiating the cells with a weak modulated laser light. The method could be used to detect hot spots and other panel-degradation issues, such as potential induced degradation (PID) peeling, cracking, and poor contacts.

July 6 is the last date to submit proposals for the ambitious ‘one sun, one world, one grid’ plan that aims at seamless sharing of renewable energy resources among countries for mutual benefits and global sustainability. The program has been taken up by the Ministry with assistance from the World Bank.

The prime minister again emphasized the need for India to develop a domestic solar manufacturing industry and also urged officials to get on with plans to make Ladakh carbon-neutral.

Madurai Kamaraj University scientists have used a pouch laminator to encapsulate a polycrystalline solar cell. The resulting device, the researchers claim, showed better UV photon absorption than solar cells treated with a polymer surface coating.

A study by Germany’s Fraunhofer Institute for Solar Energy Systems has evaluated the feasibility of horticulture PV at the site of Paras in Akola district of Maharashtra, where the state utility Maharashtra State Power Generation Co. Ltd (Mahagenco) is considering to install a ground-mounted solar system on more than 100 hectare (ha) of arable land.

MIT scientists have suggested used electric vehicle batteries could offer a more viable business case than purpose-built systems for the storage of grid scale solar power in California. Such ‘second life’ EV batteries, may cost only 60% of their original purchase price to deploy and can be effectively aggregated for industrial scale storage even if they have declined to 80% of their original capacity.
