solar panel roofing sheets 

We are mainly engaged in the designing, producing, sales of solar module and system.

a) High-efficient solar cells ensure high performance and more power under same condition.

b) High reliability with guaranteed +3% output power tolerance;

c) 3.2mm high-transparent low-iron toughened glass, EVA laminate and water-proof TPT yield long life modules while enhancing cell performance.

d) Stable, heavy duty anodized aluminum frames with convenient mounting-access, for high wind pressure and snow load.

e) Bypass diodes to avoid hot-spot effect.

f) The backside of frames is equipped with drainage holes in order to eliminate the risk that rain or snow water may accumulate in the frame through and freeze or even bend the frame in cold season.

g) Comply with IEC61215 and IEC 61730 standard.

h) Produced under systemic quality control covering all processes and factors.

Performance Assurance

1) 3 years warranty for PV module, materials and corresponding fittings;

2) 90% output of rated power after 10 years;

3) 80% output of rated power after 25 years under Standard Test Conditions;
