* Energy losses due to heat transfer from oil to steam and pumping of oil not taken into account
A power plant with SPG Fresnel collector will produce 4-14 % more
electricity from the same amount of solar energy than competitor plants !

Resumee
SPG Fresnel collector has thermodynamic cycle advantage
SPG Fresnel collectors are available on turnkey base through the
backing of German industry group MAN Ferrostaal AG
Bankability will be reached with realization of small and mid
scale power projects and process steam applications
We are ready to support your developed project by studies and
conceptual designs!
