Germanstar HP 58

Germanstar HP 58 – Quality “Made in Germany”

Germanstar HP 58 – Full glass collector with heatpipe. The start into a vacuum tube system. This double glass tube collector is proven technology for the usage of solar energy. The “round absorber” reacts fast at day break and maintains a strong performance up to the end of the day.

Key data:

  • Tube diameter 58 mm
  • Double glass tube collector with “round absorber”
  • Nearly constant yields throughout the day
  • An intelligent alternative to the flat collector
  • Very good wind behaviour when installed on stands
