Analiza efektywności energetycznej oraz rozkładu mocy wyjściowej falownika dla mikroinstalacji fotowoltaicznej w aspekcie procesu projektowania

Photovoltaic as a process of converting solar radiation directly into electricity using solar cells is one of the most important renewable energy sources. The paper analyzes the electricity generation from photovoltaic micro-installation, located in central Poland, with a maximum peak power of 1.56 kWp, within twelve full months in 2018-2019. The PV micro-installation presented is a system On-Grid, connected to a low voltage pow- er network, and the PV generator is built from the six most commonly used types of PV modules from polycrys- talline silicon. The results of the measurements were divided into percentage amounts of generated energy in two time intervals: "summer" months from April to September and others recognized as "winter". They were also analysed output power distribution of the inverter for photovoltaic micro-installation. The purpose of this analysis was to estimate the real acceptable size of the NPR (Nominal Power Ratio) coefficient, defined as the ratio of the peak power of the PV generator to the nominal power of the inverter taking into account its efficiency. Simula- tion tests were also carried out, which allowed to estimate the optimal number of PV modules connected in series in the PV micro-installation. Mariusz
