Photovoltaic deployment is diversifying beyond conventional ground-mounted plant into building-integrated (BIPV), floating (FPV) and agrivoltaic (AV) systems. These applications operate in complex environments, perform multiple functions and involve a wider set of stakeholders, so design approaches developed for ground-mounted arrays are no longer sufficient. The report argues that application context is now as important a design driver as climate, and sets out a multidimensional performance framework: energy yield per available area, self-consumption, dual-use revenue, land equivalent ratio, environmental interaction and social acceptance, alongside conventional performance ratio and LCOE. It maps application-specific stressors, failure modes and mitigation measures, reviews the limits of current energy-rating standards including IEC 61853 for integrated systems, and translates the findings into practical guidance on site assessment, component and material selection, layout optimisation, and monitoring.
