Cost-effectiveness analysis of roof-top PV systems in Montenegro and Serbia

The feed-in tariff for PV Systems in many countries have been reduced over the last few years. The purpose of this paper is to determine the level of returns, from the investors perspective, from PV projects in Montenegro and in Serbia. Two case studies are included in this paper with different sizes of solar photovoltaic systems (1.04 kW and 5.20 kW). Each case study includes three different consumption scenarios ranging from 100% self-consumption to 0%. Overall, the results show that the most profit can be made in Serbia. It is possible to triple the investment during the 25-year period with a 5.20 kW PV system. Furthermore, this study provides enormous benefit to various entities namely investors, researchers, and policy makers who are working under the solar energy domain in Montenegro and Serbia.
