研究目的
The main objective of the present study is to develop mathematical expressions for distances from objects, like walls and fences encountered on rooftops, to PV collectors deployed on horizontal, sloped, and saw-tooth roofs affecting shading losses.
研究成果
The deployment of PV collectors on rooftops may encounter shading by adjacent collectors and by obscuring structures on the rooftops, resulting in a reduction in the generated electric energy. The present study develops mainly analytical expressions for distances between walls and fences and PV collector rows for horizontal, inclined, and saw-tooth roofs. These expressions may also be applied to PV fields on the ground.
研究不足
The study focuses on mathematical expressions for distances from obscuring objects to PV collectors on rooftops. The practical application of these expressions may be limited by the specific conditions of each rooftop, such as available space and the height of obscuring objects.
1：Experimental Design and Method Selection:
The methodology for calculating the shading is based on references [3] and [4]. Mathematical expressions were developed for the distance between PV rows on horizontal and sloping grounds, facing north-south and east-west directions.
