Due to the rising quantity of bus bar, the manual operation of interconnections’ soldering becomes slower due to the many interconnection points to solder, resulting, in some cases, in a critical drop of modules per hour in the production line. With the exponentially rising number of bus bars, the area required for manual bussing will grow as well in the production space, creating situations of a non-optimized configuration of the production line.


Photovoltaic production lines need high speed, quick and reliable interconnection soldering process, enclosed in a compact footprint ensuring a higher number of modules/hour in a smaller area.

That’s why Ecoprogetti upgraded the Automatic Bussing Machine, which now performs at high speed with great efficiency, also improving the module quality.

The achieved speed is lower than 30 seconds, depending on the design of the Solar panel the cycle time can go down to 25 seconds/module.  With this high-speed cycle times, Ecoprogetti’s Automatic Bussing can manage a production line of up to 300 MW/year, increasing time and quality efficiency in a smaller footprint. The New Automatic Bussing can work with 5-6-9-12 Bus Bar or Wires, and with panels of 60 or 72 cells, half-cut cells provision is available as optional.
