Understanding the Time Evolution of the PVGIS Performance Model Parameters and the Temperature Coefficients

2018
The time evolution of the performance of photovoltaic (PV) modules has attracted increasing interest in recent years and many methods exist to estimate the performance loss rates. In this work, we analyze the relative efficiency depending on temperature, irradiance and time. To analyze the temperature and irradiance behavior we use the model adopted by

The PVGIS Relative Efficiency Model: Equations for k1 through k6

2014
The European PV Geographical Information System (PVGIS) uses a performance model based on the relative efficiency with respect to Standard Testing Conditions (STC). The efficiency’s dependence on irradiance and operating temperature is modelled with a bi-quadratic polynomial with respect to the relative temperature and the logarithm of relative ...
