3, Product Feature:
High Shunt Resistance
MARSROCK cells feature high shunt resistance.
Maximum power output even in low light conditions.
More effectively reduces hot spot risk than only screening reverse current or dark current alone.
Good performance in weak light, therefore better energy yield over the long run.
Low LID (Light-Induced Degradation)
Frequent internal monitoring of LID.
Visual Quality
MARSROCK sorts cells into four blue color classes and clearly labels them on packaging and shipping documents.
Color uniformity within cells are closely monitored and controlled.
Gives modules a high quality look and feel.
MARSROCK sets high visual quality standards, screening more than 25 visual criteria.
Low Breakage
Low breakage means lower costs or possible module re-processing.
Low breakage after shipping.
No beading, thus, lower risk of microcracks from stacking.
Low warpage and bowing, thus, reduced breakage during stringing and laminating. Engineered packaging and careful handling.
Performance in High Temperature
MARSROCK cells produce optimal power output even in high temperature conditions.
Temperature coefficients average 0.1% per °C lower than the competition. This means 3% less power degradation when cell surface temperature increases from 25°C to 55°C.
Performance in Low Light
MARSROCK cells perform exceptionally well even in low light.
MARSROCK A-grade and B-grade cells are screened for shunt resistance.
Higher shunt resistance can result in up to 10% higher annual energy yield for PV systems.
Low Reverse Current
MARSROCK cells feature low reverse current at both -10V or -12V.
Reduces hot spot risk for long-term reliability.
Environmental Compliance
MARSROCK cells are developed with environmental protection in mind.
All cells are RoHS compliant.
REACH-SVHC compliance ensures safe entry into the European market.
RoHS compliance: safe limits of Pb and no Cd found.

Test Result
Especially mentioned that you can\'t use multimeter to test the solar cells, it is not the right way!
To test solar cell should use the professional equipment, please check above photos to see how we test.
Please noted that, there have many PM points on the solar cells, use multimeter only can touch 1 or 2 PM point, it is hard to make the current come out. You can see our test equipment; there have many metal needles, almost touch the whole solar cell busbar. Normally, to use the multimeter, no matter what kind solar cells, sometime there only very less current come out, like 0.1-0.5A!
Packing Methods
Solar Cells is very fragile, to want to delivery to you safely and quickly, we will make a very stronger and careful packaging.
A: Less than 100 pieces solar cells
B: Less than 1000 pieces solar cells
C: More than 10000 pieces solar cells
