5. CSP Technology Comparison –
Parabolic Trough the Dominant Technology
Parabolic Trough Tower Dish
C urved trough reflects Circular array of mirrors Dish focuses sunlight to
solar radiation onto tube concentrate s sunlight single point , where thermal

7. Reliability of Solel’s Parabolic Trough Technology
• Solel’s parabolic trough plants have provided consistent
and reliable power generation for over twenty years
• Dependable revenue stream
• California SEGS/Solel technology has never fallen below
98% of rated capacity
• Solel has consistently evolved the technology to introduce
improved efficiencies and output
• 2002 US DOE report to Congress: “SEGS demonstrate
CSP systems achieve reliability equal to fossil-fueled
plants”

11. Solel Solar Thermal – Investor POV
Parabolic trough is mature commercial
technology = bankability
Infrastructure projects: > 40 year life
Dependable revenue stream, lends itself to non-
recourse project finance approach
Structured finance
Solel vertical control
