The Transposition Factor is the ratio of the incident irradiation (GlobInc) on the plane, to the horizontal irradiation (GlobHor). what you gain (or loose) when tilting the collector plane. It may be defined in hourly, daily, monthly or yearly values. It is computed by applying a transposition. Using solar geometry, a photovoltaic simulation tool can calculate the amount of irradiance received by a module when it is tilted rather than laid flat. The focus of this study is to compare the impact of (TF) for five cases of orientations with. This tool calculates how much solar radiation (irradiance) will actually fall on your tilted PV panels, based on the plane-of-array (POA) orientation compared to horizontal irradiance. Why this tool matters: In. This study examines the connections between essential variables that affect solar energy modeling, such as global horizontal radiation, transposition factor, global incident radiation, energy availability, and horizon band radiation. The PVsyst software evaluates two existing solar radiation.
