Streszczenie:
The theoretical foundations for assessing and calculating the energy efficiency of solar cells and panels in natural conditions of their operation have been developed. Methods for quantifying the natural solar energy flows to photovoltaic panels during the day and their modeling within the framework of the clear sky approach of the European Solar Radiation Atlas (ESRA) have been adapted. A methodology for modeling the energy characteristics of PV modules in natural operating conditions based on their efficiency indicators given in their technical documentation according to two testing standards has been developed.
