Parabolic Trough Reflector
The reflector is also a key part of the parabolic trough collector, Vicot makes it with quality glass at high shape precision with silver coating for excellent reflectivity, and 6 different layers in total, as shown in next diagram, insures high reflectivity, durable life time and strength.
Features- Made of high quality glasses with silver coating
- Durable, with the life expectancy available in over 20 years.
- Free from hailstone damage.
- Mirror reflectivity ≥ 93.8%.
- Strength test: 1cm-diameter steel ball falling from high up.
