Features:

• Thin film solar module has following features:
  • High-power output for framed thin film silicone solar modules
  • More than 30% lighter than double glass thin film solar modules
  • Made from non-toxic materials, no need to concern about the harmful gas emission or material decomposition in the whole lifespan of solar modules
  • ASF technology delivers high-energy yield per rated Wp, owing to a low-temperature
