Winfried Wahl, head of product management at Longi Solar spoke to pv magazine about how the HiMo4 has a 15% higher power output than the previous iteration in the series.
With market penetration exceeding expectations in 2018, bifacial technology is set to account for one third of global solar module production by 2022, writes Edurne Zoco, Research Director at IHS Markit. Bifacial and half-cell technologies are rapidly gaining momentum due to their improvements in power output, along with their low implementation barriers and minimal capex requirements
Chinese PV manufacturer Trina Solar today announced it has achieved a new efficiency record of 24.58% for a cell based on n-type monocrystalline TOPCon technology. The record has been confirmed by the ISFH CalTeC laboratory in Germany. Meanwhile, fellow giant Canadian Solar also hit a new milestone with its cast mono technology, reaching 22.28% conversion efficiency on a 157mm² wafer.
Module technologies such as bifacial, half-cut, multi-busbar (MBB), and shingled are maturing after two years of improvement. Comparing module technologies, we see that half cut has a high degree of maturity in production equipment, high yield rates, and output climbing since the beginning of 2018. From late 2018 to 2019, most companies have expanded or upgraded their portfolios by pairing half-cut technology with MBB technology.
The device, conceived for large scale solar, is said to solve the instability issues associated with the two-modules-in-portrait structure and to have the largest south-north slope seen in the tracker industry.
There are four PV projects and all the facilities will use bifacial panels provided by the Brazilian factory of the Chinese-Canadian manufacturer.
The German panel maker said the new factory, which will add to its 525 MW facility in China, will expand its production capacity to 1 GW. With plans in the pipeline to enter the PV project business, that figure could rise to 2 GW by the end of next year.
Things are hotting up in the tracker world as the desire to squeeze down the price per Watt of solar power intensifies. And the rise of the trackers is attracting some well-known businesses to buy their way into the field.
The Changzhou-based company, which has established the Shanxi facility with state-owned rival Shanxi Lu’An Photovoltaics Technology, has not revealed what proportion of the factory’s output will feature the high efficiency technology.
The Chinese panel maker is already producing bifacial half cut modules at its new Anhui fab after the completion of an initial 2.5 GW phase of operations. And the company president confirmed Longi is on track for 45 GW of mono wafer and ingot production capacity next year.
