MARSROCK is a high-tech enterprise intergrating research and decelopment, Xiamen Mars Rock Science Technology Co., LTD. is a professional supplier of solar products for more than 7 years. We can not only supply our customers top quality products, but also provide our reliable and careful service to our customers. Most of our products are approved by CE, ROSH and FCC certificates. If you have special requirements about some products, you also can contact with us. We will be appreciated to help you always.


1.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.

2.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.

3.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.

4.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.

5.Color uniformity  among cells and within cells:

Color uniformity, good texture, also looks very comfortable

6.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.

7.Low reverse current

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

Reduces hot spot risk for long-term reliability

8.Low LID(light induced degradation)

9.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.
