This study investigates the techno-economic feasibility of producing hydrogen with integrated solar-hydrogen panels and supporting balance-of-plant equipment, using a process model linked to an hourly solar model. The results show that scale is the main driver of cost reduction: the LCOH drops from about 49 €/kg at 1,000 panels to 9.1 €/kg at 100,000 panels and 7.3 €/kg at 10 million panels. Hydrogen storage lowers costs at small scale by improving utilization of expensive components, but slightly raises costs at large scale due to added capital expenses. With higher efficiency (23%) and lower panel costs (120 €/m²), hydrogen could reach roughly 3.8 €/kg, highlighting the importance of scale, efficiency gains, and cost reductions for affordable green hydrogen.
