Motives for the Use of Photovoltaic Installations in Poland against the Background of the Share of Solar Energy in the Structure of Energy Resources in the Developing Economies of Central and Eastern Europe

Increasing the use of renewable energy sources (RES) is one of the greatest challenges faced by modern emerging and developing economies. Its effective implementation largely depends on the acceptance and involvement of consumers in the process of sustainable energy transformation. Bearing in mind the above premises, the purpose of this article is to identify the motives for the use of photovoltaic installations in Poland against the background of the share of solar energy in the structure of energy consumption in the developing economies of Central and Eastern Europe. In order to achieve this goal, the scope of the use of renewable energy sources in 11 countries of the analyzed region was determined in the course of the research; then, on the basis of the results of the survey, the motives for using solar energy by 754 Polish prosumers were identified (a statistically representative sample). The results indicate a low and relatively slow-growing use and a very different structure of RES in the surveyed economies. From the pro-consumer perspective, the decision to use solar energy is primarily influenced by economic motives, including, above all, the possibility of reducing costs and using energy also for heating. Independence factors related to the possibility of at least partial independence from energy suppliers and diversification of energy sources are also important. Ecological motivation and promotion of RES, including government incentives, are definitely less important.
