Power supply for autonomous systems is commonly provided by photovoltaics (PV), especially for civil engineering applications, where seamless integration of PV with landscape is a valuable asset. The design rules for autonomous systems are always highly climate and application dependent. In the engineering practice, the systems are commonly over-sized or under-sized, and largely fail to meet the expectations in terms of economy or supply-autonomy. This paper investigates the application of PV for powering the safe pedestrian crossing, with all-night illumination, using detailed solar irradiance data for Polish climate. The results show the realistic forecast of energy deficits and give the design rules for optimal system size.
