There is a threshold at which big becomes too big when it comes to PV module sizes, argues Hongbin Fang, the director of product marketing at Longi Solar. Fang recently said at pv magazine’s Roundtables USA event that despite size limits, there is still a lot of efficiency and cost-reduction potential to come.

HJT technology could fill an innovation gap in the residential and commercial rooftop PV market, and boost U.S. solar leadership through domestic manufacturing of cells and modules.

French startup Wind my Roof has developed a new wind power system equipped with two rooftop PV modules. It is currently testing a prototype in Paris.

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.

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 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.

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.

First, the bad news: PV modules will be caught up in the global wave of inflation. After a very brief respite, prices are picking up again for almost all module technologies. But the changes recorded for early October are paltry compared to the price increases still to come, writes Martin Schachinger of pvXchange. As of the cutoff date for this market survey, some manufacturers had already announced even more significant upward corrections for future deliveries. The price adjustments shown in the October index are thus only a tentative start to rises of no less than 15-20% over the price levels that prevailed just a few weeks ago. However, this will probably be the last price correction we can expect at the manufacturer level until the end of the year.
