A Solar Panel
This example demonstrates how BERT models engineered energy systems following Bertalanffy's principle that "the whole is greater than the sum of its parts." The solar panel exemplifies Mobus's 7-tuple framework: components (cells, coatings, diodes), network (electrical interconnections), governance (MPPT control), boundary (panel encapsulation), transformation (photon-to-electron conversion), history (degradation over time), and temporal dynamics (diurnal and seasonal variations).
