Large-scale renewable energy sources with tremendous potential include concentrated 
solar power, which is currently attracting attention due to its use and room for growth. Due 
to their higher efficiency when compared to photovoltaic, parabolic trough solar collectors 
(PTSCs) in particular are becoming more and more popular. This work aims to assess the 
performance of a planned 24-m-long PTSC model in a 10m3
/day solar MED water 
desalination plant with a 2.2m3
storage tank. Oil served as the working fluid in a glass 
heat-collection element. Based on seasonal data for average intake and outflow 
temperatures and surface temperatures for Cairo's climatic conditions, the suggested 
model's authentication is supported.
