CPV plants data analysis. ISFOC and NACIR projects results

Now it is the moment for CPV to become a reliable solution for large scale electricity generation, because it is one of the technologies with higher efficiency, and moreover, it has still margin for improvement. In order to continue with this development, it is important to introduce, in the design of the installations, all the lessons learned during the operation of pilot plants. This paper presents the operation results obtained at the ISFOC pilot plants, during the first three and a half years of operation, and the NACIR project. The CPV technology is not demonstrating signs of degradation which could reduce its high capability of transforming light into electricity. From the operation issues, valuable information is obtained in order to improve the design, turning CPV prototypes into an industrialized product ready to compete with other technologies, making a great effort in the reduction of the installation costs.

Comparative study of internal and external thermal insulations based on PET waste bottles

We present a comparative study of internal and external thermal insulations in two pilot rural houses in the mountainous cold region of the middle atlas in the Dayet Aoua region, province of Ifrane, Morocco. In both studies we used plastic waste bottles (PET bottles) in cavity walls and roofs. The idea is to increase insulation by reducing convection fluxes in wall cavities using cheap insulating materials. We recorded temperatures in different rooms of each house before and after insulation as well as the ambient temperature outside the houses for a long period of time. Our study shows a significant increase in room temperatures translated in an important reduction of wood burning and better household comfort especially during the cold season.
