2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC).
Photovoltaic (PV) modules predominantly are mass manufacturing products with narrow variability. For Building Integration of PV (BIPV) customers and architects demand for a wider product range, particularly in size and color. Additional requirements
