Technical and economic evaluation of photovoltaic panels: a case study based on interdispciplinary approach

Abstract. This study evaluates the performance of SoliTek SOLID B.60 bifacial photovoltaic panels in four Lithuanian cities; Vilnius,
Klaipėda, Telšiai, and Dotnuva, each representing a distinct climate zone as defined in national classifications. Using the System Advisor Model (SAM) and standardized 2022 weather data from NSRDB, the same technical system and a merchant plant financial model were applied across all cities/ to ensure comparability. Key performance indicators; energy output, capacity factor, levelized cost of energy (LCOE), and Net Present Value (NPV) were analyzed. Results show Klaipėda outperforms other cities in both technical and financial metrics, while Vilnius yielded the lowest performance. The study highlights the advantage of using locally manufactured panels and consistent simulation parameters for realistic assessment. Use of interdisciplinary evaluation approach allows to take into account main technical panels’ performace indicators together with economic attractiveness. This approach is especially promising in the context of increasing global competition in the area of photovoltaic industry.
