Renewable energy is an opportunity not only to improve the energy efficiency of individual customers, but also to ensure energy security for local governments. In 2007, in Lublin province 5 municipalities have formed a partnership government called "Valley of Zielawa". The objectives of the partnership is the cooperation in the field of education, tasks in the field of culture, health protection, social welfare, fire protection and street lighting. One of the overarching goals of the partnership include ensure energy security and improving energy efficiency through the utilization of solar energy. Solar energy resources in the Lublin region are mainly characterized by a very high degree of sunlight compared to other regions of the country. The greatest potential for solar energy use is the eastern area of the province (including the area of partnership). In order to ensure the energy security of the community established a company Energy Valley of Zielawa, which in 2014 built a photovoltaic farm with a capacity of 1.4 MW in the Bordziłówka in Municipality Rossosz. This paper presents an analysis of photovoltaic farm work over the year and a half and the analysis of the energy efficiency of various types of photovoltaic panels which produce energy on a farm in photovoltaic Bordziłówce.
