Features

MARSROCK has been in the PV industry for many years, our reliability and quality are represented in every solar cell we sell. MARSROCK solar cells offer the following 10 quality advantages:

 

High Cell-To-Module(CTM)  ratio

MARSROCK improve CMT ratio by: 

Narrow down efficiency bin rage to 0.2%.

Defining efficiency bin by minimal power and 97% of  current max  power.

 

Optimized  energy output even in low light or high temperature:

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.

 

Long-term stability and relaibility:

Strong bus bar interconnection ability with minimum peel strength >1.2N/mm.

High quality paste and optimal firing conditions to reduce possible delamination.

Constant pressure cook tests, damp heat tests and peel strength tests.

 

Low overall breakage rate:

Standard package that meets the long-distance transport of fragile objects packaging requirements.

No beading, thus, lower risk of microcracks from stacking.

 

Color uniformity  among cells and within cells:

Color uniformity, good texture, also looks very comfortable

 

Visual quanlity:

We can provide you solar cells  125*125mm for home or commercial or industrial etc. We set hight visual quality standards,sreening more than 25 visual criteria. Work time more than 25 years.

 

Low reverse current:

MARSROCK cells feature low reverse current at both -10V or -12V.

Reduces hot spot risk for long-term reliability

Low LID(light induced degradation)

 

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.

 

Envaironmental  protection:

REACH-SVHC compliance ensures safe entry into the European market.

ROHS compliance: safe limits of Pb and no Cd found.

If order amount is less than 1000pcs, above solar cells with different printing will be randomly shipped, it is according to our stock to arrange without advanced information.

 

While bulk purchase, if you have special requirment on it, please kindly contact with us directly, we can customize for you. 

Usages

Solar cell is very thick and fragile. And it is easy to be oxidation if expose in the air for a long time. So it can't apply directly in the practice. However, After professional lamination, it can be manufactured by solar panel. 

 

Solar cell is the key material for making solar panels. solar cell quality and efficiency are the most important factors to influence the quality and efficiency of solar panel. If you want to make good quality and high efficiency solar panel, then you should choose good quality and high efficiency solar cells.

 

 Besides solar cell, other raw materials for making solar panel includes tempered glass, solar EVA film, tab wire, bus bar wire, flux pen, TPT backsheet, junction box, etc.  If you have requirements of these raw materials, hope you can consider us first. All materials can be supplied high quality and reasonable price for you.
