lp68 Junction Box and Connector have a high degree of waterproof, effectivelyresist the harsh environment
The junction box carries a current of 15A, ensuring high current flow throughthe modules
Glue-spilled tank has a doubletayer waterproof, cross-section with hook-shapedaluminum frame.enhanced by 10% of the mechanical load strength
The module refines the current division, thus effectively reducing the loss of up to2% due to mismatch and increasing the power output of the system
resistanceExcellent salt spray ,anti-ammonia and anti PID, TUV, SUD certificationapproved
Passed the 2400pa wind load and 5400pa snow load test, ensuring that themodule has a stable mechanical life
Modules are packaed accordina to color classification, to achieve consistentappearance after installation
LINEAR PERFORMANCE WARRANTY12 Year Product Warranty · 25 Year Linear Power Warranty0.55% Annual Degradation Over 25 years |
START WITH A HIGH PERFORMANCE MONO PERC CELL | LASER CUT THE CELL INTO FIVE STRIPS | APPLY ELECTRICALLY CONDUCTIVE ADHESIVE TO EACH STRIP | OVERLAP THE CELLS INTO FIVE STRIPS |
SHINGLED MODULE | NORMAL MODULE |
Compared with the normal module technology, the interconnected material of shinqledmodule is different from that of normal module, whose technology is simpler and more reliableavoiding the defects such as deviation of ribbon and cold soldering |
