In this study, a new type of solar and wind hybrid power generation system that enables to simultaneously generate power by solar and wind power is proposed. This new hybrid power generation system mainly consists of a tower with attached solar modules attached and a windmill. While solar modules are being operated, the air inside the tower is hotter than the ambient outside air and therefore less dense than the ambient air. Such a difference in temperature causes the bottom of the tower of inside air to have a lower pressure than the pressure at the bottom of the tower of outside air. The higher pressure outside the tower is the driving force that moves the outside air into the tower and also moves the air up and out of the tower. This movement is called the stack effect. Besides, a wind power generator that can be driven by the airflow generated inside the tower is installed at the top of the tower and generates power. It can be said that this new hybrid system actively utilizes heat which is a disadvantage of the current solar power system. As a basic study for the development of solar and wind hybrid power generation system, pressure differences between outside and inside the tower caused by various conditions and the draft flow rates induced by the stack effect were analyzed and presented. It was found that available pressure differences and draft flow rates increase with the air temperature inside the tower and the tower height. However, the increase of air temperature outside the tower shows the opposite results, lowering pressure differences and draft flow rates.
