Abstract
These days, there are desire to use renewable energy. One of the renewable energy is solar energy. Solar energy is almost no impact on environment. However, since solar irradiation depends on climates, it is unstable. For this reason, we should grasp detailed characteristics and finally develop efficient driving control plan for the solar thermal energy systems. We focus on two types of the solar collectors, flat plate type solar collector and evacuated type solar collector. High precision mathematical models are developed to grasp the characteristics of these two solar collectors. With these model s, we first simulate them. And then we carry out experiment to investigate the validity of the models. As a result, we grasped the characteristics of two type solar collectors, and confirmed the validity of the mathematical models we have constructed.
