Cost efficiency while maximizing power output is the name of the game in solar project development and asset management. And the automation of the provision of utility scale solar operations and maintenance (O&M) is fast becoming one of the most compelling opportunities. Help shape the future of automation in solar O&M by completing this first-of-its kind survey.

A new US Department of Energy report describes the challenges of commercializing perovskite technology for the solar energy sector.

Researchers in Singapore have developed a new technique in which polycrystalline silicon is pulverized into powder and pelletized into ingots. The process relies on spark plasma sintering to dope the silicon with germanium and phosphorus.

Scientists in the United States have fabricated a triple-junction solar cell that reached 39.5% efficiency – a world record for any type of cell under one-sun illumination. Though relying on materials and processes that are still too costly for most commercial uses, the concept could soon see actual applications in powering satellites and other space-bound technology.

The solar supply chain problems that began last year with high prices and polysilicon shortages are persisting into 2022. But we are already seeing a stark difference from earlier predictions that prices would decline gradually each quarter this year. PV Infolink’s Alan Tu probes the solar market situation and offers insights.

Kore, an energy startup in California, has developed a new way to produce hydrogen from biogas, and is now poised to build a commercial-scale demonstration facility in Los Angeles. It said half of the carbon in the feedstock can be converted into gas, while the other half can be converted into solid elemental carbon char.

Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modeling assumed a typical commercial building in Los Angeles.

South Korean battery manufacturer LG Energy Solution presented its latest innovations at the Smarter E event in Munich last week. It also announced its transition from nickel-manganese-cobalt (NMC) battery chemistry to lithium iron phosphate (LFP) in its future products.

Rooftop and ground-mounted solar deployment is reportedly slowing down in Bangladesh due to rising prices of panels, inverters, and other PV system components.

US scientists have developed a way to remove snow and ice from solar panels at a much faster rate than conventional approaches. It is based on a glass coating on a film with high optical transparency and superhydrophobicity.
