In recent years, Longi has turned its attention to green hydrogen. Li Zhenguo, company founder and CEO, speaks with Vincent Shaw in Shanghai about the strategic shift and how coupling this technology with solar PV will be key to achieving carbon neutrality.

New research from Lappeenranta University of Technology shows that there is no single correct orientation for a PV installation.

Scientists in China have developed a new recycling process for PV modules that can recover intact silicon cells from end-of-life products, and process them back into wafers. As part of the recycling process, the wafers are purified and surface-treated, making them suitable for integration into new, high-efficiency cells and modules.

A couple of weeks ago, Goldman Sachs sent shockwaves through battery metals markets, issuing a prediction that cobalt and lithium in particular were due for a sharp price decline in the next two years. But London-based Benchmark Mineral Intelligence is loudly pushing back, outlining its reasons why it believes the call on lithium was wrong. Meanwhile, US analyst Wood Mackenzie says that the battery raw material chain will remain tight, but notes that recycling could help to ease the supply deficit.

Longi Solar outlines its high-temperature mitigation logic in designing the lower current, high-wattage Hi-MO5 solar panel series.

In many parts of the world, project developers and owners are increasingly looking to floating PV as the next long-term growth market in utility-scale solar. Gian Schelling, global business development manager for Hitachi Energy, says that PV-on-water can rise above the current challenges it faces by drawing on the lessons learned from offshore wind development.

As Australia battles an energy crisis, the United Nations secretary general has called for increased investment in renewables, saying it is the only “true path to energy security”, warning new funding from governments for fossil fuel exploration or production is simply “delusional”.

A research group led by UNSW’s Professor Martin Green has published Version 60 of the Solar cell efficiency tables.

There is enormous demand for renewables to enter the grid, and for power purchase agreements to make use of them. However, as more renewables feed into the grid at intermittent periods, the risk of “revenue cannibalisation” increases. Swiss consultancy Pexapark’s latest report looks at the “cannibalisation effect” and how the solar PPA market can adapt.

The International Renewable Energy Agency’s latest annual report on the progress towards the United Nation’s sustainable development goal seven estimates 670 million people will still lack electricity in 2030, and more than 2 billion will be reliant on unhealthy, polluting cooking methods.
