The aim of the research work is to study methods, which can allow sustainable and reliable manufacturing of concrete elements with the use of solar energy. The first method is determination of reasonability and time of effective employment of solar energy subject to climatic characteristics of the manufacturing area. The second method is prediction of the probability of reduction of the solar insolation in the estimated manufacturing period. The third method is reservation of additional material resources to increase parameters of reliability and stability of the manufacturing. It is necessary to use these methods as comprehensive approach. The research results allow reducing costs for manufacturing of concrete elements as compared with traditional technology and getting the finished products with keeping the specified work schedule. It is especially important for mobile polygons (mobile building sides), which are used to quick arrangement of manufacturing of concrete elements, including timely reconstruction works in the location of the occurred catastrophe in conditions of destroyed industry, unavailability of providing energy and material recourses.
