The precision of yield calculation modern design and simulation software for photovoltaic systems strongly rely, beside the accuracy specified module inverter data, on quality weather data. Since data from stations is not available most locations world-wide this calculated by using interpolation methods. Beside this, typically uses historical In work mismatch results based proprietary meaning interpolated or also called synthetical coming a station in proximity to installation evaluated. simulated sets are compared measurement as obtained output hence give profound understanding how may influence results. outcome shows that simulation, if increased factor up four on-site used input simulation. largest source deviation irradiation, which varies 10% measured irradiation compared. second sources mismatches power temperature correction.
