Introduction<\/h2>\n\n\n\n

A solar fa\u00e7ade system, also known as a Building-Integrated Photovoltaic (BIPV) fa\u00e7ade, integrates photovoltaic modules into the building envelope. It generates electricity while serving as a protective and architectural component.<\/p>\n\n\n\n

    The ontology development followed Noy & McGuinness (2001) steps: define scope, list terms, structure classes, define properties, create instances, and test with a reasoner.<\/p>\n\n\n\n

    Engineering Examples<\/h2>\n\n\n\n

    Three Engineering Examples for the Solar Facade System Ontology<\/strong><\/p>\n\n\n\n

    1) Electrical Behavior Analysis<\/strong>
    Engineers designing photovoltaic (PV) fa\u00e7ade systems can use the ontology to represent and analyze the electrical structure of modules, including solar cells, bypass diodes, and string connections, to assess how shading or temperature affects performance.<\/p>\n\n\n\n
