The technologies using of renewable sources energy like photovoltaic panels and solar collectors were used in Europe, mainly in southern countries (like Spain) until recently. EU policy of sustainable development and technological development impact on increase of popularity of those technologies in northern European countries like Poland. The research problem of the work is to determinate the appropriate conditions for the location of above-mentioned technology (panels) in the cityscape. The numerous examples of its destruction were noticed because panels were located using only energy efficiency conditions. The research methodology was based on “in situ” research (Bialystok-Poland, Cordoba – Spain) in order to determinate the categories of urban landscape in which panels are located. Technical, climatic, landscape and composition conditions were analysed in order to establish assessment of completed investments. The result of the science work are categories of the urban landscape views in Bialystok and Cordoba, ie architectural and landscape encloses (streets, squares, public gardens), city panoramas. The proposed methodology of assessment of cityscape impact are applicable to the planning, designing and investment process for Bialystok and Cordoba. They could be used to another cities also in necessary condition of taking into account the individual characteristic of cityscape. The proposed conclusions can be used in the planning, designing and investment process of another cities due to protection of their cityscape values.
