The article deals with the concept of a one-dimensional array of solar panels integrated with outdoor LED lighting systems. In this paper, the technique of determining and calculation the main parameters of series photovoltaic structure and outdoor LED lighting according to illumination requirements have been proposed. The possible structure of reversible converter for integration with low voltage power grid has been suggested. The basic features of reversible converter for interconnection series photovoltaic structure with low-voltage power grid were simulated and analyzed as well.
