Spanish mounting system provider Alusín Solar has developed a solution to enable the transit of installers on roofs. It has recently commissioned a production line for this product, which it dubbed Carex.

Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules.

Commodity trader Trafigura and Oslo-based ammonia leader Yara International ASA have signed a Memorandum of Understanding that will see supply of clean ammonia as well as joint R&D projects as the two companies look to promote clean ammonia as a shipping fuel and develop its value chain and infrastructure.

Widespread green hydrogen deployment will be key to achieving stringent climate targets, and German hydrogen demand is set to grow from the 80 TWh range in 2030 to between 400 TWh and 800 TWh by 2050, according to a new joint study by several Fraunhofer-related entities.

An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.

Private sector fossil fuel spending on exploration is drying up just as modest rises in clean energy investments are being observed. With stock market investors increasingly embracing renewables, the IEA has observed positive signals in its latest energy investment report, but warned we are still doing far too little to keep global heating at bay.

Module manufacturers have once again adjusted their prices upwards. This is already the third or fourth price increase in the last six months, and there is no end in sight, writes Martin Schachinger of pvXchange. But why is it so hard to achieve long-term, sustainable development in the global solar market, at least on the part of manufacturers? Few other industries are so turbulent, with constant swings between excess supply and bottlenecks, between price collapses and price rises – and always to the breaking point of the market. Yet again, planning security is out the window.

As PV manufacturing lines continue to get larger, keeping track of the measurement data that’s vital for quality and process control becomes an ever more herculean task. Flashing equipment supplier h.a.l.m. has developed a software solution that keeps all of this data in one place and provides operators with a real-time view of production line performance and quality. pv magazine caught up with Managing Director Michael Meixner to discuss the latest on big data in PV manufacturing.

The proposed technique is based on radiative cooling and consists of a glass coating made with a two-dimensional subwavelength nanostructured grating, which is imprinted in soda-lime glass and has enhanced mid-infrared emissivity, and a micro-structured grating. The temperature decrease provided by the nano-micro-grating coating was found to be approximately up to 5.8 degrees Celsius.

The system, developed by Spanish specialist Alusín Solar, is being tested by Endesa in a 9.8 MW project for self-consumption. The mounting structure is made with aluminium bars that, instead of being fixed to the roof with screws, are attached through a double-sided adhesive.
