This paper deals with the energy performance of a new integrated solar storage collector (ISSC) with compound parabolic concentrator (CPC) conceived in the Thermal Process Laboratory in CRTEn Borj Cedria (North of Tunisia). The novelty in this system is the use of transparent vacuum insulation in the annulus between double half-Cylindrical Plexiglass, and the use of automated nocturnal insulation system, which suppresses heat loss during night. Also, the system is equipped with a mobile support permitting to have many collector orientations toward south, east-south, and west-south in order to maximize the incident solar flux. The experimental study of the ISSC system showed that the thermal loss coefficient of ISSC system is equal to 6.16 W/K

This paper deals with both energetic and economic studies of a new integrated collector storage with honeycomb transparent insulation (ICSHTI) which was conceived, developed, and tested in the Research and Technology Centre of Energy (CRTEn), Tunisia. Experimental and numerical studies were performed in order to evaluate the thermal and the economic performances of the new solar collector configuration. Investigations are
