Modules & Upstream Manufacturing

Few doubt that aluminium frames will be a part of the solar module for some time to come. And with PV manufacturing continuing to scale, the carbon footprint of this versatile metal may prove a sustainability challenge.

It remains unclear why Chairman Jin Baofang was detained, but the company said its operations will not be affected. The Paper, a Chinese state-owned media outlet, reported that Jin’s detention might be connected to the fall of Liu Baohua, the formal deputy director of the National Energy Administration, which has also been under investigation by the anti-corruption authorities since mid-October.

PV modules are being sold with ever longer warranties, but when modules underperform or fail, making claims on those warranties is rarely straightforward. So are the warranties worth the paper they’re written on? Where does this leave installers? And how can this liability be mitigated?

An International Energy Agency report led up by Rolf Frischknecht from Treeze in Switzerland and under the joint project management of the University of New South Wales’ José Bilbao has measured the lifecycle emissions of both residential solar PV with battery storage and gas-generated grid electricity. The results are not particularly surprising, only the Morrison Government’s ongoing obduracy is.

In a new paper published in the journal of Renewable and Sustainable Energy, renowned PV scientist Pierre Verlinden examines the solar industry’s trajectory towards the 70 TW of installed capacity that will be needed by 2050, as the best choice for meeting climate targets set out in the 2015 Paris agreement. Silver consumption and recycling, according to Verlinden, will be the biggest challenges in the years to come, as well as ensuring balanced growth and avoiding a major installation rush in the years close to 2050.

South Korean-based manufacturer Q Cells has launched its first “made for Australia” solar module and in a show of confidence, the Q-Maxx-G2 comes complete with an extended 15-year product warranty.

Stable pricing, stable product performance, and rapid after-sales service: These are the pillars on which Chinese PV manufacturing giant Longi’s rapid growth in the Australian market are built – says Stephen Zhang, the MD of Longi Australia. And as the company moves towards another year of doubling its shipments to Australia, its local presence and team remains a vital part of its strategy.

Scientists led by the U.S. National Renewable Energy Laboratory (NREL) have developed a new stress testing protocol for PV modules, one designed to simultaneously expose modules to multiple stresses, as they likely would be in the field. Putting modules through this test, the researchers have already been able to reveal new information regarding backsheet degradation, and they promise new insights into other degradation mechanisms both known and unknown as well.

In an update to its International Technology Roadmap for Photovoltaics, the German engineering association the VDMA said that solar module sizes of up to 4.0m² may be brought to mass production in the future.

The Korean manufacturer has announced that it wants to enforce the recall of products made by rivals Jinko Solar, Longi Solar and REC Group that were deemed by the regional court of Düsseldorf in June to have infringed a passivation technology patent. The recall applies to products sold since January last year in Germany.
