All of Hilight Solar has passed 100% TUV flash test, TUV , CE , IEC, CEC, ISO certificate.
competitive price photovoltaic solar panle 250W with TUV
Quality Characteristics are as below:
1)High-efficient solar cells ensure high performance of solar modules and create more power under same condition.
2)Average power of PV modules is within positive tolerance.
3)3.2mm high-transparent low-iron toughened glass,EVA laminate and water-proof TPT yield long life module while enhancing cell performance.
4)Stable,heavy duty anodized aluminum frames with convenient mouting-access,for high wind pressure and snow load.
5)Bypass diodes to avoid hot-spot effect.
6)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 trough and freeze or even bend the frame in cold season.
