This paper deals with extremely distributed energy harvesting from individual PV cells and their small arrays that can easy be placed in convenient locations of an existing object and integrated into its natural infrastructure. With this approach energy is produced in places wherever it is possible and spend as close as possible to energy generation location. As an example, an office building is discussed where PV cell can be placed on the blades of vertical jalousies and naturally positioned against sun. A physical model of such system with small (120W) amount of PV cells, interface converters, solar tracker and low (12V) voltage lighting grid is presented. Different versions of PV connections and interfacing are analyzed. It is concluded that various configurations are applicable, but the groups producing voltage closer to 12V are more efficient.
