Cost effective

The HELIOtube is a highly innovative type of solar concentrator with plastic films as its key component. The results are significant advantages in capital expenditure and operating expenses. Therefore, the HELIOtube allows 55 % cost savings and significant reductions in CO2 emissions over the entire lifecycle compared to the most advanced glass mirror based parabolic trough technologies.

Materials & Structure

Conventional parabolic trough: Conventional parabolic troughs are characterised by heavy and fragile glass-mirrors.
Inflatable HELIOtube: An inflatable lightweight technology made out of plastic films with significant cost reduction.

  • Lightweight technology
  • Cost efficient
  • Reduced complexity

Production process

Conventional parabolic trough: Assembly lines require much space and skilled labor to cope with the high complexity

HELIOtube technology: “Roll-to-Roll” mass production realize economies of scale and reduce space needed

Transport & Logistics

Conventional parabolic trough: Special transportation is needed as well as complicated upload and download processes.

HELIOtube technology: Pratical shipping and transport in standard 40-foot sea freight containers.
