Abstract
These days, There are a lot of environmental problems which we should solve, so we must use renewable energy, One of renewable energy is solar energy. The amount of solar energy is infinite. In addition, solar energy is no risk of environmental pollution when we use. Though, solar irradiation depends on climates so it is unstable energy source. So, we should simulate efficient plan and control. For this reason, we aim at constructing high precision Mathematical model. In this essay, we have constructed Mathematical model of flat plate water collector and evacuated glass tube solar collector. In addition, we have xperimented and validated Mathematical model.
