Preliminary decision announced on U.S. solar cell imports
The preliminary decision on countervailing duties on cells from companies in Vietnam, Cambodia, Malaysia and Thailand are lower than some expected for several major Chinese producers.
Turkey exempts four large manufacturers from anti-dumping duties applied to 5 countries
The Turkish authorities applied an anti-dumping tariff of $25/m2 solar modules imported from Vietnam, Malaysia, Thailand, Croatia, and Jordan.
PV system sizing for 100% self-consumption
A group of researchers has proposed a new method for the sizing of PV systems that do not rely on an anti-dump system and operate without the possibility of injecting power into the grid. The novel approach requires an estimate of the annual hourly profile and the minimum power demanded, as well as the use of an irradiance meter and an electrical network analyzer.
Wattstone launches new concrete bases for rooftop PV
The German company said its new products are suitable for PV systems with tilt angles ranging from 0 to 15.6 degrees.
Storing solar power through aluminum-rock composite
UK-based Caldera has developed a new heat storage technology that can reportedly convert on-site generated solar power into on-demand heat, thus replacing conventional gas boilers. The system uses a composite of recycled aluminum and volcanic rocks to store heat at up to 500 C and produce steam.
Lightweight self-attaching PV system for zinc roofing
Créawatt unveiled this week a new version of its ultra-light Luxsiol photovoltaic system for zinc roofs. It weighs only 3.25 kg/m2 enabling all types of flat roofs made of bitumen, PVC, ethylene propylene diene monomer rubber, or T333/T250 steel sheet.
Silver price on the rise
The price of silver has increased over 30% since the beginning of the year, with a particularly strong increase being registered in the last few months.
SEG Solar begins work on 5 GW solar cell factory in Indonesia
SEG Solar (SEG), a Texas-based module manufacturer, has started deploying n-type cell production lines in Indonesia’s Kawasan Industri Terpadu Batang industrial park, 390 km east of Jakarta.
Indian researchers present 28%-efficient silicon-perovskite tandem solar cell
A research group at the Indian Institute of Technology Roorkee has fabricated 4-terminal silicon-perovskite tandem solar cells with power conversion efficiency of 28%. The team is now scaling up this technology to match 18.2 cm x 18.2 cm, commercial M10 solar cells dimension.
German startup unveils ‘self-aligned’ back-contact TOPCon solar cell
EnPV GmbH has developed a TOPCon solar cell concept featuring a novel type of back contact technology. The cell can reportedly be produced at signifcantly lower costs compared to conventional TOPCon cells and its manufacturinng process is claimed to be easy to introduce in existing TOPCon production equipment.
