Retrofit of a parabolic trough solar field with a solar tower
The project Resol (Retrofitting Solarthermal Power Plants) is a cooperation of MAN Diesel and Turbo SE in Oberhausen, the Solar Institute of Jülich and DLR. The objective of the project is to analyze the possibilities to reduce levelized electricity costs by adding solar towers to existing parabolic trough plants within a package of retrofitting measures. MAN Diesel and Turbo SE is in charge of the overall project coordination.
The graphs below show performance characteristics for the seasonal variations, for parabolic trough respectively solar ttower power plants located in Spain. The challenge is to create a combination of the two technologies that maximizes the use of the plant throughout the whole year, and not only for the design point.
