The hype surrounding green hydrogen is real, but does the cost-reduction outlook for its production technologies live up to it? Christian Roselund looks at the technology, transportation, application and enabling policies behind the promising green energy carrier.

Sand and dust are a PV plant operator’s worst nightmare. Performance losses due to soiling, or “the dust effect,” are a cause for innovation among O&M providers, particularly in dry and dusty regions that are otherwise ideal locations for large-scale solar installations. Yazeed Al-Mousa examines the latest robotic cleaning solutions, as well as the software and sensors that help plant operators with the tricky economic decision of when to actually start cleaning.

Bluetti’s NA300 sodium-ion solar generator offers thermal stability, fast-charging capacity, low-temperature performance, and integration efficiency.

The title of Martin Schachinger’s October market commentary was “Module prices set to rocket back to 2019 levels.” This month, he writes that prices have already reached December 2018 levels and notes that there is no reversal in sight. Prices for all module technologies have once again risen by an average of 3 percentage points since last month.

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.
