Metal roofing has become a driver for roof type selection in many cases because not only is a metal/solar roof system less expensive upfront than other roof system combinations, but it also leads to improvements in the lifetime return on investment of the system.

UK researchers have revealed that gaseous hydrogen could cause problems in natural gas pipelines, while electrolyzer manufacturer Nel has announced plans to build a second production line in Norway.

Deepak Thakur, the former chief of Sterling and Wilson’s hybrid and energy storage business, has joined Mahindra Group’s cleantech arm Mahindra Susten.

A new report form analysts at IHS Markit notes that the market for module-level power electronics (MLPE) grew by 33% between 2019 and 2021, with around one-third of new residential solar installations now taking advantage of MLPE’s promise of improved safety, energy yield and fault detection. And with smaller, distributed generation systems expected to represent 43% of global PV installations between now and 2025, the opportunity for MLPE will only get larger.

In a study that began in 2016, US scientists purchased 834 PV modules, representing seven manufacturers and 13 module types, and installed them in various climate conditions to observe their performance over time. The results show that, while plenty of opportunities still exist to extend module lifetimes and reduce performance loss in the field, reductions in the manufacturing cost of PV have not come with an increase in their degradation rate.

Laser contact opening (LCO), a standard process in PERC cell production, has seen little market development in the past few years. Stiff competition from equipment suppliers in Asia, combined with the fact that most new n-type manufacturing doesn’t make use of LCO, has kept the level of interest here quite low. However, as the PV research community increases its focus on reducing silver consumption, new approaches to cell contacting and metallization provide impetus for a second look at laser processing.

New research from Stanford University researcher Mark Jacobson outlines how 145 countries could meet 100% of their business-as-usual energy needs with wind, water, solar and energy storage. The study finds that in all the countries considered, lower-cost energy and other benefits mean the required investment for transition is paid off within six years. The study also estimates that worldwide, such a transition would create 28 million more jobs than it lost.

Rob Barnett, a senior clean energy analyst for Bloomberg, forecasts a 30% increase in global PV deployment this year, and double-digit growth through 2025.

A new study shows that hydrogen could be produced for as little as AUD 2.85 ($1.98) per kilogram, supporting Frontier Energy’s plans to make green hydrogen from a 500 MW solar project it is developing in Western Australia.

Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.
