Abstract

Abstract: Heliostat field layout design is a critical task in solar tower power plant construction due to its impact in the final plant efficiency and cost. The complexity of these systems and the high number of parameters to define during the field design stage demand the use of suitable simulation tools to compare different design options and evaluate the final performance of the heliostat field. This work concerns a comparison of some of the most common tools used for the heliostat field layout design and analysis, aiming to help Concentrating Solar Power researchers and industry by providing more information regarding the tools comparative results and features. A brief review of available tools is presented, including an extended description of some of them – Tonatiuh, SolTrace, TracePro and CRS4-2. A qualitative comparison of these four tools is performed focusing on functionality and usability. A quantitative comparison is done providing simulation results for a test-case, the SPSS-CRS facility located at Plataforma Solar de Almeria in Spain. In general, the results for total power and maximum irradiance are in good agreement across most tools. The total power values are very close for Tonatiuh, SolTrace and CRS4-2. Apart from the designer preferences, the choice of the most suitable tool depends on the specific application and requirements.
