Analysis of the snow effect on the photovoltaic power systems' performance by modeling

While the use of renewable energy sources is becoming widespread, many research and development studies are carried out to increase the application areas of photovoltaic power systems. In particular, research on system parameters affecting productivity and productivity is increasing every passing day. In this study, effects of snowfall on production values of photovoltaic power systems were investigated. In the simulation programs, which are commonly used, the snow load accumulated on the panel surface in the days following the snowfall is prevented. Within the scope of this study, a meaningful connection was tried to be established by comparing the production values of a photovoltaic power system established in Erzurum province where heavy snowfall is observed and the estimated data of a simulation program used in the preparation of power plant feasibility reports for two years. According to the results obtained in the light of limited data, for a day reinterpreted with the profit model, when the total daily production values are considered, 90% proximity to the actual production value is obtained compared to the initial results of the simulation. However, it should be kept in mind that this result corresponds to only one day in the data set and the model shows significant deviations on different days. Since there are many climatic parameters that affect snowfall and residence time, it should not be overlooked that the result of the study is a local assessment for the designated plant.
