The ETS2100 is an advanced tabber and stringer machine that can process 2100 solar cells per hour for soldering in photovoltaic applications. It uses an infrared soldering system or Ecoprogetti's patented hybrid soldering head to solder thin solar cells without breakage. Key features include high throughput, low breakage rate below 0.2%, compatibility with various cell sizes and types, and quick changeovers. It also offers high soldering quality, reliable throughput, flexibility, and low operator requirements.
