Comparison of predicted and real parameters of PV systems in the Czech Republic and Spain

ArticleThis paper compares predicted performance by a simulation software for a given new constructed PV system of crystalline silicon technology located in Prague with 10 kWp peak power and a similar system in Spain. Simulation software used for the sake of this paper was publicly available PVGIS from the website of its creators, parameters were set to be the same like in the real PV system. The difference between the predicted and the real data was calculated and then discussed in the result section of this pape r. Suggestion how to increase the accuracy of the prediction by the simulation software is in the discussion part of this paper
