APPLICATION OF CLOSE-RANGE DIGITAL PHOTOGRAMMETRY IN SOLAR PARK DESIGN
Abstract
In recent years, the growing demand for renewable energy sources has placed high demands on the accuracy and reliability of the input data in the design of solar parks. The aim of the study is to present an integrated methodology combining the use of close-range digital photogrammetry to create a digital model and analysis of solar radiation according to the energy potential of the terrain. The main emphasis is on the application of a double-overflight method with an unmanned aerial system at different flight altitudes, to achieve homogeneous planar and elevation accuracy. The ways to achieve this accuracy are indicated, through the method of implementing the double-overflight and estimating the base/height ratio, Ground simple distance (GSD) and Real time kinematic (RTK). The research is complemented by the integration of climate data (EPW) in a parametric environment (Rhino/Grasshopper with Ladybug Tools) to perform an analysis of the solar radiation. The method has been applied in the design of the photovoltaic park "Elidis Solar". It is shown that south-facing surfaces reach 1600–1700 kWh/sq.m/year, while north and shaded areas have lower potential. Data processing achieved about 0.85 cm planar and about 2.35 cm elevation accuracy, improving over single-shot photogrammetry. The conducted experiments and the obtained practical results confirm the conclusion that the technological process includes the methods of close-range digital photogrammetry and climate-based assessment of solar radiation allows for the simultaneous achievement of homogeneous planar and elevation accuracy of the terrain model and possibilities for its energy assessment.
