Estimation of the Optimum Energy Received by Solar Energy Flat-Plate Convertors in Greece Using Typical Meteorological Years. Part I: South-Oriented Tilt Angles

The optimal solar radiation received on an inclined surface is always critical for energy purposes at a location or in area. Therefore, many attempts have been made worldwide to calculate the optimum tilt angle this purpose. present study gives answer about south-oriented inclination inclinations of panels Greece maximum efficiency. analysis shows that 25° (and 30° some cases) facing south most appropriate. To this, sums surfaces with angles 0–60° step 5°, including φ° (φ being geographical latitude) 33 locations were analyzed monthly, seasonally, and annually. data used work comes from corresponding typical meteorological years (TMYs) generated above locations. TMYs are first time by tilted south. Four new zones defined cover whole Greece.
