S.O.L.I.D. is an Austrian solar thermal engineering company specialising in all aspects of large-scale solar thermal energy plants. Since 1992, S.O.L.I.D. has been planning, building, delivering, assembling and operating large-scale solar plants (50 m² – 5.000m²) around the world, providing hot water, room heating, industrial process heat, district heating and cooling. SOLID currently builds some of the largest commercial solar cooling projects in the world. With its unmatched experience in design and operation of large-scale solar plants, S.O.L.I.D. is both a pioneer and one of the world’s leading companies in the solar thermal industry. S.O.L.I.D. also offers finance solutions, ESCo services, for large solar thermal plants mainly for solar district heating and solar cooling.

Main activities: 

  • Turnkey solutions for large scale solar cooling, solar thermal  district heating, solar thermal process heat and cold, DHW and heating
  • Planning, engineering, designing, constructing and monitoring of large scale ST plants
  • Energy contracting 
  • R&D

With the tele-monitoring solar control system IP-Solar which we co-designed, the control of the design data and an alteration of nominal values are easily managed. In this way the plant can be optimized, trends can be interpreted and malfunctions can be analysed and eliminated via computer diagnosis.
