Comparative study of grid-tied photovoltaic (PV) system in Kathmandu and Berlin using PVsyst

The performance of solar photovoltaic cell depends on the geographical location and technology implemented to harness the available energy. Nepal is situated along the solar belt of 30° northern latitude and it is blessed with an average of 300 days of sunshine a year. Nevertheless, the total electric energy generated by different sources has been unable to meet the demand. So, including aforementioned facts, there are several reasons which advocate that Nepal has high potential to do research, develop and implement various photovoltaic technologies to generate additional solar energy to minimize the present energy crisis. This paper presents comparative analysis of grid-tied PV systems of Kathmandu and Berlin using PVsyst. The total amount of electric energy generated by PV arrays that can be fed into the grid and different losses that occur in the systems are analyzed and results are provided graphically.
