As a result, a Moroccan mapping of solar water heating systems is presented in this work. This mapping concerns two technologies commonly used： the FPC （flat plate collectors） and the ETC （evacuated tubes ones）. It is based on three criteria： firstly, the efficiency of the STC （solar thermal collectors）; secondly, the economic aspect and at last, the reliability requirements. Based on these information, the multi-criteria outranking methodology PROMETHEE （preference ranking organization method for the enrichment evaluations） allows us to define an adequate solar heater technology linked with the climatic zoning of Morocco.展开更多

A new approach was adopted with the use of a two separated cards, the smart and power card in a scalable concept. This module allows a more saving of energy in comparison with the fixed systems for PV （photovoltaic） application and allows hire performances for CSP （concentrated solar power） systems. It provides a significant added value for higher power applications in comparison with the existing system. The developed sun tracking system is autonomous, flexible, scalable and low cost system.展开更多
