Photovoltaic panel shadow occlusion test method

The method is based on accurate solar position calculations and uses the properties of convex objects 1 and their shadows for identifying the affected areas of the PV arrays and reducing the computational power demand. . In this paper, an algorithm capable of modelling shadows from nearby obstructions onto photovoltaic arrays is proposed. The. . The invention discloses a photovoltaic panel shadow occlusion diagnosis method based on IV curve scanning, which comprises the following steps of: s1, analyzing the efficiency of the group cascade system: and calculating the string-level system efficiency according to the string real-time data, and. . An actual test is carried out for the completed photovoltaic project with building shadow the output performance of the PV array with building shadow occlusion. Partial building shadow occlusion is a kind of occlusion with certain regularity. . Various factors such as nearby structures, trees, or even weather conditions can cast shadows on PV panels, leading to a significant decrease in their efficiency. It is not 77 in proprietary software packages. In photovoltaics it is important to analyse shading caused by surrounding objects and/or vegetation.
