Most photovoltaic modules are planar and as a result, research on panel layout for photovoltaic systems typically uses planar panels. However, the increased availability of thin-film photovoltaic modules opens up possibilities for the application of flexible solar panels on irregularly curved surfaces, including the integration of photovoltaic panels on building roofs with double curvature. In order to efficiently arrange photovoltaic panels on such surfaces, geometric CAD tools as well as radiation analysis tools are needed. This paper introduces a method to generate geometry for flexible photovoltaic modules on curved surfaces, as well as a method to arrange multiple of such modules on a surface. By automating the generation of possible photovoltaic panel arrangements and linking the geometric tools to solar analysis software, large numbers of design options can be analysed in a relatively short time. This combination of geometry generation and solar analysis provides data that is important for electrical design of photovoltaic systems. The merits of the methods we introduce are illustrated with a case study, for which hundreds of design configurations have been explored in an automated manner. Based on analysis of the numeric data generated for each of the configurations, the effects of panel dimensions and orientation on solar insolation potential and panel curvature have been established. The quantitative and qualitative conclusions resulting from this analysis have informed the design of the photovoltaic system in the case study project.

“…In the past decade, prototype anticlastic, flexibly formed shells have been constructed by West [99], Pronk et al [39], Tysmans [40], Pedreschi and Lee [28], Seracino et al [41] and Veenendaal and Block [45]. Veenendaal and Block [45,100] have used a hybrid of fabric formwork with an adjustable cable-net to provide increased flexibility of form, as shown in Fig. 12.…”

To assess the reliability of the results of numerical modeling were used algorithms based on the verification of the conservativeness of difference schemes used [7,8,9]. Energy consumption at the heating surface Ths = 543 K for 1 day will be: Σ con1 = T·V·C=8·27.84·5=1113.48 rubles (12) By increasing the speed of pulling, the cost of the finished product is greatly reduced.…”
