Solar power plants – Alternative sustainable approach to greener environment: A case of Slovenia

By encouraging the use of alternative renewable energy sources, Slovenian legislation triggered desired investments in the field of solar power plants. However, whether or not such projects present a profitable investment is an issue individuals as well as companies have to deal with. This paper aims to present a calculation assessing the cost-effectiveness of an investment in a photo-voltaic system in a case where such energy is used for transport needs in an average family or company. Calculations have been made based on data obtained in the Republic of Slovenia at the beginning of 2010 and indicate an acceptable return on investment.

► The energy budget of Slovenia.
► To investigate the actual solar radiation in Slovenia.
► Energy balance of energy consumption of the average family with an electric car.
► A calculation assessing the cost-effectiveness of an investment in a photo-voltaic system.
► Reduction of CO2 emissions due to the integration of a photo-voltaic system.
