Austria-based Luvata has introduced an online solar ribbon calculator designed to help photovoltaic module manufacturers optimize solar ribbon weight, ribbon length per spool and ribbon length per solar panel.
Luvata says PV module manufacturers can use the Sunwire Calculator to optimize the amount of Sunwire ribbon per spool to accommodate the speed of tabbing machines and shift changes. In addition, it provides the opportunity to further refine module materials and Sunwire ribbon for improved module efficiency and to reduce overall material costs.
The Sunwire Calculator requires a few details to determine the solar ribbon weight, the ribbon length per spool and the ribbon length per solar panel. The results are made available immediately and can be emailed directly to an email address. Users can determine the solar ribbon weight based on the copper width, copper thickness or coating thickness or the length of Sunwire depending on the number of cells and busbars per cells.
