An ecol. life cycle analysis (LCA) of the 1 MW solar farm located in northern Poland was performed. The eco-indicator 99 method was chosen as the basic calculation procedure. The levels of environmental impact harmfulness were detd. in the area of individual stages of the LCA object (prodn., operation, post-use management). Human health, environmental quality and depletion of raw materials were used as main factors in the study. Guidelines for pro-environmental, post-use management of plastics, materials and components of solar power plants were given.
