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 of maintenance and it can all be performed by the operator without the need of continuous interventions of Ecoprogetti’s technicians;
Quick remote assistance and supervision via 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

OPTIONALS

12 BUS BAR

Optional Kit

The 12BB soldering system developed by Ecoprogetti makes the soldering process easier and gives the opportunity to boost the power output of the pv module.

Kit for Cut cells

Solar stringer machine dedicated to cut solar cells

The ETS700 Stringer can be equipped with a kit developed to manage and solder cells from 52×156,75 mm up to 156,75 x 156,75 mm (Adaptable to work with M4 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 ETS700. The machine maintains the ability to manage cells of standard size and with the possibility to manage small sized cells. This guarantees a high flexibility of the whole production line. It’s possible to switch to a different configuration in a very short time.

Tray Ecolayup

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 in to the storage trays. Due to the use of a soft vacuum system there is no risk of cell breakage.
