This study aims to achieve two main objectives. The first one is the study of solar heating systems, with an emphasis on the passive types, and the second is the study and design of a new model of passive solar air heating system. Thus, this text is divided into two parts, the theoretical study of solar systems and the design of one. It is also worth mentioning that during the designing process, the model shifted from a passive solar air heating system to a water heating, and power producing system with a photovoltaic.
    The paper begins with a brief introduction to solar heating systems followed by a detailed presentation of their already existing types. Then, it moves on to discuss the advantages and disadvantages, different versions, applications, and functions of passive solar air heating systems. Finally, this part of the study ends with the decision to design a thermosiphonic panel, as decided above.
    The second part of the study begins with the research and the new design for the solar passive heating system. Then, the text carries on to justify the choice of the cellular morphology of the system and continues to present the technical aspects and installation guidelines, and to provide a description of the way the solar panel works.
    This study concludes with two variants of the system, " green cells" and "window cells", designed specifically considering the aesthetical aspect of the installation.
