Viridian Solar unveils roof-integrated solar panels with power of 335/340 W

The new devices feature efficiencies ranging from 20.7-21%. The panels are said to be compatible with a wide range of slates and tiles, include special fixings for different batten thicknesses, and achieve the highest fire rating and wind resistance without modifications to the roof.

IESA partners Norway’s Greenstat to support India’s hydrogen mission

India Energy Storage Alliance (IESA) and Greenstat Hydrogen India will collaborate on establishing a Norwegian Centre of Excellence on Hydrogen in India and supporting the development of green hydrogen technologies.

Quantum dot solar cells and the search for stability

In various forms, quantum dot technology has attracted plenty of attention among PV researchers recently. And as efficiencies have crept past the 15% mark, the community is beginning to look at other factors limiting the viability of quantum dot solar cells in a commercial setting. Scientists in Germany examined the degradation mechanisms affecting different quantum dot materials; and suggest a standardization of stability testing to enable comparability of results.

Modeling the potential of lead-free perovskites

Scientists in India modeled the performance of tin-based perovskite (methylammonium tin triiodide) finding that with careful optimizations the material could achieve efficiencies beyond 28%.

New model to predict PV module cleaning cycles and resulting profits

A group of scientists in Bangladesh has developed a model to determine the optimal cleaning schedule for a PV installation at any location in the globe, requiring only the average insolation and soiling rate for a given site to make the calculation. The study also draws new conclusions regarding the influence of sandstorms and rain on soiling, and aims to be among the first studies to paint a global picture of soiling trends by region.

IIT Bombay, BHEL in race to develop high-efficiency solar cells

India’s Ministry of New and Renewable Energy is funding the research to develop high-efficiency crystalline silicon solar cells, including those with passivated emitter and rear contact structure, and perovskites.

DST to fund trans-national research in digitalization for green energy transition

February 17 is the last date to submit proposals targeting implementation, adaption, and knowledge creation of digital solutions in energy systems and networks. The projects will be funded by the Department of Science and Technology, under India’s Ministry of Science and Technology.

LG Electronics offers hybrid system combining heat pump, PV and storage

The system generates electricity and heat for residential houses and small businesses. An integrated energy management system should guarantee maximum self-consumption of the solar power produced.

Panasonic to exit solar manufacturing

The Japanese brand will continue to sell third-party-made modules under its brand in its home market, as it already does overseas, but in-house PV wafer, cell and module production will halt by the end of fiscal year 2022.

The long read: Compressed air storage to be more than just hot air in Israel

Solar-linked projects will be developed by domestic firm Augwind and will feature underground storage tanks. One of the systems will be built by French energy giant EDF and will feature a 20 MWh compressed air storage system and 5 MW solar array.
