Fully automatic tabber and stringer machine with patented innovative hybrid soldering system which allows soldering of the photovoltaic cells without thermal stress. The machine can be interfaced with a XY Layup System or a XYZ Robotic system for an automatic Pickup & Positioning of the Solar cells on the Glass.
Breakage less than 0.2%
Patented hybrid soldering technique
Works with PERC, HJT, Bifacial, Mono/Poly cells, half-cut cells and cut cells
High soldering quality; more than 2N in peel test (1.5mm ribbon) over the complete cell’s surface;
Reliable throughput with constant quality;
Integrates a camera to detect the broken cells before soldering;
Only one operator for three ETS700 equipped with layup station;
Automatic change of solar cells’ basket;
Pre and post heating of the cell in soldering phase in order to avoid thermal stress;
Stretching and fluxing of the ribbon before soldering;
Special design for thin solar cells, 160 µ;
Adjustable tab & soldering length;
Touch screen with embedded computer;
Online troubleshooting thanks to ethernet connection of the machine;
The number of solar cells for the string is settable from the touch-screen;
Settable distance between the cells from 2 mm to 35 mm;
Pre-treatment of the ribbon NOT necessary;
This machine has very little need for maintenance and it can all be performed by the operator without the need for continuous interventions of Ecoprogetti’s technicians;
Quick remote assistance and supervision via the internet;
Predisposed to be interfaced with other equipment;
High precision alignment between serigraphy and ribbon performed both optically and mechanically
String flipping device on the unloading belt
Kit for Cut cells
Solar stringer machine dedicated to pre-cut solar cells
The ETS700 Stringer can be equipped with a kit developed to manage and solder cells from 30×156,75 mm up to 166 x 166 mm (Adaptable to work with M6 cells). Thanks to this kit it’s possible to have an excellent PV panel production with small-sized cells. The kit for cut cells enables to extend the capacity of the ETS 700. The machine maintains the ability to manage cells of standard size and with the possibility to manage small-sized cells. This guarantees high flexibility of the whole production line. It’s possible to switch to a different configuration in a very short time.
Tray layup system suitable for ETS700
Ecoprogetti’s TRAY ECOLAYUP is an automatic safe storage system for strings made both with full size and cut cells.
The strings are loaded from the flipper of the stringer machine and then are gently positioned into the storage trays. Due to the use of a soft vacuum system, there is no risk of cell breakage.
Our technicians and staff of Ecoprogetti srl is at your disposal for any clarification or specific questions about our PV production equipment and for the realization of your specific solution.
