Abstract: Solar photovoltaics (PV) stand at the centre of one of the most significant technological and economictransformations of the twenty-first century. By 2025, global solar deployment has accelerated tounprecedented levels, driven by steep declines in the Levelised Cost of Energy (LCOE), new industrialpolicies, innovation in cell architectures, and rapid maturation of power-electronics-based grid support.Yet the solar transition is also confronting structural asymmetries, including manufacturing overcapacity,material supply chain bottlenecks, and uneven environmental regulations. Solar PV has shifted from acost-driven expansion model to a more complex ecosystem where efficiency, resilience, grid stability,and sustainability increasingly determine long-term competitiveness. Advances in n-type TOPCon cells,heterojunction devices, and perovskite-silicon tandems-along with emerging grid-forming (GFM) invertersystems-are redefining how solar plants interact with modern electricity networks. At the same time, therise of inverter-dominated grids challenges long-standing assumptions about inertia and system strength,pushing operators to adopt new forms of synthetic inertia and voltage support. Environmental pressures,especially those relating to lifecycle emissions, module recycling, and perovskite toxicity, highlight theneed to integrate circular economy frameworks. This paper provides a holistic, interdisciplinary synthesisof economic, technological, operational, and environmental evidence shaping the global solar ecosystemfrom 2025 to 2030. It argues that the coming decade will be defined not only by the pursuit of efficiencybut by the integration of intelligence, resilience, and circularity into the core of solar system design.
