Abstract: Two profiles of concentrated evacuated tube heat pipe solar collectors made of single-sided and double-sided absorber have been analyzed and compared under control conditions and results presented in this paper. These innovative concentrated evacuated tube heat pipe solar collectors were experimentally tested at a tilt angle of 60° to the horizontal. Using in-door solar simulated experimental conditions temperature response, collection efficiency, heat loss coefficients and energy collection rates as well as the incident angle modifier (IAM) were recorded and compared at five different transverse angles (0–40°) at 10° increments.
