Should heterojunction solar technologies be temporarily shelved? Could copper plating replace screen-printed silver conductive surfaces in cells? Why are tandem cells a likely successor to PERC? Brett Hallam recently sat down with Natalie Filatoff in Sydney to explain the findings of a new study by UNSW that sought to answer these controversial questions.

Developed by Spanish manufacturer Alusín Solar, the new mounting system is claimed to be, currently, the only one on the market that provides six fixing points for a solar panel in ballast-secured structures.

The Indian Renewable Energy Development Agency Ltd (IREDA) shall provide its techno-financial expertise to help Brahmaputra Valley Fertilizer Corporation Limited develop renewable energy, green hydrogen, green ammonia, and energy efficiency and conservation projects.

There is still much to debate over the benefits of moving a vehicle via solar, but the market has been getting creative and is evolving quickly.

While the adoption of large-format wafers has driven a wave of capacity expansion for PERC, existing manufacturers and new entrants continue to evaluate TOPCon and HJT. An increasing number of HJT pilot lines and gigawatt-scale capacity expansion projects are appearing, as manufacturers see the advantages of fewer process steps, higher efficiency ratings, and better yield rates. The localization of equipment is also a driving factor. PV InfoLink’s Derek Zhao offers an update on the latest developments and process routes for HJT.

The R&D center under the Department of Science and Technology has indigenously developed lithium battery cells and packs for application in two-wheelers and solar street lamps.

The kit consists of one or two modules, a microinverter, and a five-meter cable. Thanks to its plug-in technology, it can be connected to any electrical outlet and immediately begin generating electricity.

U.S. solar thermal specialist Fafco is set to launch a new photovoltaic-thermal heat pump solution for water and pool heating. The system consists of photovoltaic-thermal panels, a 5 kWh thermal battery with a heat pump, and an electric hot water heater.

As power systems integrate more digital and inverter-based devices, the guidelines and technical standards for these resources are evolving, and none as quickly and urgently as cybersecurity standards. New approaches to cyber defense are now needed to protect more interconnected systems with diverse owners, manufacturers, and system architectures. However, current cybersecurity standards for energy devices are still patchy. Upcoming efforts are aimed at changing that, reports NREL’s Connor O’Neil.

The private-sector power producer will group its renewable energy business under wholly-owned arm JSW Neo Energy as it targets growth in renewable energy generation, energy storage, and green hydrogen business.
