Modules & Upstream Manufacturing

The Gujarat-based solar manufacturer plans to have 1 GW of cells and 3.7 GW of module capacity operational in 2023.

Mitrex Integrated Solar Technology has developed a new solar panel with 19.5% efficiency that measures 2,036 mm x 1,992 mm x 40 mm and weighs in at 42 kg. It can operate with a system voltage of 1,000 V and has a power temperature coefficient of -0.36% per degree Celsius.

German engineering and consulting firm Viridis.iQ GmbH will assist in conceptual design to construction and commissioning of the 4 GW vertically integrated poly-to-modules solar factory.

Developed by scientists in Turkey, a system prototype has operated at lower PV module temperatures and removed most of the dust accumulation. The researchers are now planning to improve the device by applying MPPT converter topologies.

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.

The Gujarat-based solar module manufacturer, which currently has 400 MW module fab operational, is expanding capacity to 1 GW with the addition of 600 MW mono PERC line. Having started EVA film manufacturing, it also plans to get into the production of aluminium frames and backsheets.

The three-day solar exhibition kicked off today at Helipad Exhibition Center in the Gandhinagar district of Gujarat. On the first day, Indian solar manufacturers Adani Solar, Pixon, Saatvik among others shared with pv magazine their aggressive plans to ramp up production capacities and launch new technologies. We also caught up with inverter player Invergy, which plans to open its manufacturing capacity soon in India.

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.

In an update to its annual International Technology Roadmap for Photovoltaics, German engineering association VDMA discusses the readiness level for various technologies in PV cell and module manufacturing, finding that more process development is needed for 210mm wafers – the largest format currently on the market – to match the throughputs that will soon be achievable with smaller formats including 182mm.
