The use of computer simulations and measurements in determining the energy efficiency of photovoltaic installations

摘要

The paper presents an analysis of the energy efficiency of a photovoltaic installation connected to the AC power grid. Forecasting of energy yield was carried out in two ways: with the use of PVSol software, as well as physical measurements of daily electricity production. On that basis, a statistical correlation between the results obtained from measurements and computer calculations was determined.
