Cell-To-Module Performance (CTM)

MARSROCK improves cell-to-module ratio by:

Narrowing down efficiency bin range to 0.2%.

Defining efficiency bins by minimal power and 97% of current at maximum power.

Customers can manage and control module power output distribution.

Customers get more value for their money.

Long-Term Reliability

High Shunt Resistance

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.

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.
