solar panel manufacturing process and machines

1. MANUFACTURING
PROCESS OF
SOLAR PANEL

2. MANUFACTURING PROCESS OF
SOLAR PANEL

3. CELL TESTER MACHINE

4. FUNCTION
 TO CHECK THE SOLAR CELL PARAMETERS SUCH AS –
• MAXIMUM CELL POWER, Pm (WATT)
• OPEN CIRCUIT VOLTAGE, Voc (VOLTS)
• SHORT CIRCUIT CURRENT Isc (AMPERE)
• MAXIMUM POWER CURRENT, Ipm (AMPERE)
• MAXIMUM POWER VOLTAGE, Vpm
• SERIESE RESISTANCE OF SOLAR CELLS, Rs (OHM)
• PARALLEL RESISTANCE OF SOLAR CELLS, Rsh (OHM)
• SOLAR CELL EFFICIENCY ( %)
• FILL FACTOR (%)
• LIGHT INTENSITY
• TEMPRATURE.

5. FIBER LASER SCRIBING
Laser Scribing Machine.
• Forced Air Cooling.
•NO water required.
•Very High Speed.
•No Spares like Diode,
Lamp required.
•Higher transfer efficiency,
•lower running cost (2KVA)
•Module and compact
structure, smallest size.
•Narrow cutting kerfs
(30μm) and more smooth
edge.

6. FUNCTION
• Scribing or cutting the Solar Cells and Silicon
Wafers in solar PV, including the (mono
crystalline silicon) and poly- si (poly crystalline
silicon)solar cells and silicon wafer.
• According to our need we can cut the solar
cells.

7. RIBBON CUTTING MACHINE
This machine is used for cutting of ribbons as
required for solar cells.

8. AUTOMATIC SOLAR CELL
STRINGER MACHINE

10. FUNCTION
• Automatic Tabbed Stringer for CUT CELL & FULL
CELL (any size from 30mm to 156mm).
• Suitable for 5”,6” square cell and rectangle cut
cells.
• Possibility to change from 2, 3, 4 Bus Bar cell
• Adjustable cell holder (no need of kits).
• Fully Automatic string unloading on tray.
• Breakage rate::≤0.3, for cut cells rate::≤.5%
• Special design IR Lamp.

11. FILM CUTTING TABLE
This table is used for cutting EVA and back sheet for
solar panel.
The EVA and PV back sheet is designed to protect
the inner components of the module, specifically
the photovoltaic cells and electrical components
from external stresses as well as act as an electric
insulator.

12. GLASS WASHER MACHINE
•This machine is used for washing glass of solar
panel.
•It cleans the glass and after cleaning make it dry.

13. LAYUP STATION
This machine is used for assembling of cell string , EVA,
back sheet /PET on glass and after that giving connection
of panel.
Also used for checking short circuit current and open
circuit voltage.

14. PROCESS OF ASSEMBLING

15. EL TESTER MACHINE

16. FUNCTION
• This machine is used for defect detection of
panel.
• It detect the faults like braking or cracking of
solar cells.

17. SOLAR PANEL MODULE
LAMINATOR

18. FUNCTION
In the manufacturing of photovoltaic
modules, the laminator machine is of
fundamental importance in curing the EVA, to
join the layers that form the module and
remove all air from between them. When the
materials in the photovoltaic module have
been placed on the glass, they undergo a heat
treatment that converts the EVA into a type of
gel that encapsulates all the layers to form a
very strong and compact sandwich.

19. AFTER LAMINATION SOLAR
PANEL

20. AUTO CORNER CUTTING
SAW

21. FUNCTION
This machine is used for aluminum corner connector
profile cutting into right angle pieces.

22. ALUMINIUM MULTI PROFILE
CUTTING OFF SAW MACHINE

23. FUNCTION
This machine is designed for cutting 45 degree V-shaped
grooved of aluminum profile.

24. FOUR HEAD PNEUMATIC
PUNCHING MACHINE

25. FUNCTION
This machine is used for aluminum profile punching
holes.

26. DOUBLE HEAD CUTTING
SAW

27. FUNCTION
This machine is designed for cutting Aluminum profile
at the angle of ± and

28. GLUE GUN AND SEALANT

29. FUNCTION
• Sealant act as a moisture barrier and
provide insulating coating.
• Provide mechanical strength to solar
panel.
• Also used for sticking the junction box on
panel.

30. FRAMING MACHINE

31. FUNCTION
Aautomatic Solar Module Framing Machine is
used to assemble solar module automatically.

32. SUN SIMULATOR MACHINE

33. FUNCTION
This machine is used for testing the technical parameters
and shows the relation between voltage, current and
power of solar panel after assembling.

34. Panel checking glass

35. NEW ADDITION TO THE
ARMOUR
Used for string making for 3 watt to 20 watt panel
