Sol.CT: A technology based on two major principles

Design of a bearing structure made of ultra-high performance concrete.

Direct Advantages

  • 2.5 times cheaper than steel

  • Very low wind-related deformation 

  • Over 30 years durability

  • Global ease of construction 

  • Ultra-simple civil engineering and foundations reduced to a minimum

Approximation of a perfect parabola by means of several adjacent portions of flat plate mirrors bent mechanically at ambient temperature

Direct Advantages

  • 4 times cheaper than thermally curved mirrors

  • 10 times lower optical error

  • 3 times higher wind resistance
