CELL INSPECTION

Camera for detection of broken cells before soldering

OPTIONALS

Camera Inspection

Camera inspection for alignment and broken cells detection

The camera inspection system developed by Ecoprogetti make the soldering process easier and gives the opportunity to improve the production output.
This system permits to detect the broken cells before the soldering process. Ecoprogetti’s camera inspection is even able to detect the micro-crack cells, making the process more efficient and without wasting time for the cell replacement after the soldering. The damaged cells are automatically put in a specific basket.

Kit for Cut cells

Solar stringer machine dedicated to cut solar cells

The cut cells are the best choice for small modules suitable for stand alone solutions.
The tabber stringer machine ETS700 can be equipped with a special kit for solder and manage the cut cells.
This equipment use the Ecoprogetti’s innovative patented hybrid welder to solder without mechanical and thermal stress. It’s the best solution for very thin photovoltaic solar cells and for ribbon cells (EFG).

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.
