The drastically increase in energy demand and the problems resulted from environmental
pollution have led to a serious trend towards energy utilization efficiency improvement through
scientific researches related to renewable energies, particularit
y that Syria has a high solar
irradiance and prolonged sunshine hours.
This research focuses on determining the thermal efficiency for a prototype of a parabolic
trough solar concentrator (PTC) to obtain the optimal prototype thermally and economically
according to climatic conditions in Damascus.
It has been deposited the mathematical model of the studied concentrator depending on the
calculated design parameters through calculating the solar angles equations and direct solar
irradiance throughout the year. And it has been solved this model by using numerous computer
programs (Excel, EES).
