This is lot for: 1. 72 SOLAR CELLS
WHOLE cells - NOT BROKEN / NOT SPLIT! 3" x 6" cells Factory Cell Specifications: Average Power (Watts): 1.80 Wp Average Current (Amps): 3.5 Imax Average Voltage (Volts): 0.5 Vmax Thickness 0.2 mm
The term "B Grade" refers to SOME cells having some stains (or other small cosmetic issues) from tabbing process (most of them do have solder on the back - because cells was tested and prepared ( by the factory) to be connected for the PANEL). ATTN! beware of CLEAR back TABBED cells - were are LOW power - because got rejected even BEFORE got connected for Panel !!!
ALL Cells are FULLY tabbed
2. Bus Wire (to connect cell stringd together on the panel) 20' ...........$10 value (according to factory you will NOT need any Solder - it's already plenty of it on the wire itself ) Bus WireGAUGE: 0,2000MM WIDTH: 5,0000MMMATERIAL: 62SN/36PB/2AG TINNED COPPER SOLDER COATING THICKNESS: 400-600 MICROINCHES/SIDE
you do not need tabbing wire - ALL cells ARE fully tabbed by the factory 3. Rosin activated Flux Pen .............$8 value
Rosin Pen Flux Dispensing Pen #186, .33 Oz Kester 186 flux pen allows controlled application of flux eliminating the mess from flux bottles. Chisel point, spring loaded tip dispenses just the right amount of flux. The Kester Flux-Pen stops waste while limiting operator exposure to soldering chemicals. Rosin flux contains a mildly activated rosin (RMA) type flux approved under MIL-F-14256 for military grade soldering. Residue may be left in place or removed using a solvent.4. 4x 6-AMP 6A 1000V BLOCKING DIODES FOR SOLAR CELL PANEL............. $7 value Axial Lead Silicon Rectifier Diodes Maximum Repetitive Peak Reverse Voltage: 1000V Maximum RMS Voltage: 700V Maximum DC Blocking Voltage: 1000V Maximum Average Forward Rectified Current (60Hz, resistive or inductive load. Derate current by 20% for capacitive load): 6A Peak Forward Surge Current (8.3ms single half sine-wave superimposed on rated load-JEDEC Method): 400A Operating Junction and Storage Temperature Range: -55° to +125°C
Maximum Forward Voltage (IF=6A): 0.95V Maximum DC Reverse Current at Rated DC Blocking Voltage (TA=25°): 5uA Maximum DC Reverse Current at Rated DC Blocking Voltage (TA=100°C): 400uA Typical Junction Capacitance (VR=4V, f=1MHz): 100pF Maximum Thermal Resistance Junction to Ambient: 10°C/W
