Heliac Solar Thermal

A cost-effective renewable energy source using high-temperature solar-generated heat

July 2020

Heliac Solar Thermal

A cost-effective renewable energy source using high-temperature solar-generated heat

  • World Alliance Member
  • Featured Solution
  • Labelled Solution
Label Date July 1, 2020
By Heliac
From Denmark
Maturity stage TRL 9 / CRI 3-4 - Commercial Scale Up / Multiple commercial Applications

The solution is based on Heliac's invention of a new, low-cost method for producing transparent lenses that work like magnifying glasses. Each solar collector is 20m2 and rated at 14kW. The solution integrates into existing systems that produce heat for industrial processes in such a way that heat is delivered when the sun shines, but when the sun doesn't shine, the users just use their existing heat generating systems. Thanks to this system, there is no need for storage and no risk of running out of energy.

The Environmental Benefits

  • The solar collectors are 99% recyclable and can be manufactured from 90% recycled materials
  • This solution has an energy payback time of 3-6 months

The Financial Benefits

  • ROIs of 3-5 years for project developers
  • Immediate payback for end-users with no need for upfront investments
