Analysis of energy efficiency and output power distribution of the inverter for photovoltaic microinstallation in central Poland
AbstractPhotovoltaic 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. The PV micro-installation presented is a system On-Grid, connected to a low voltage power network, and the PV generator is built from the six most commonly used types of PV modules from polycrystalline 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 analyzed output power distribution of the inverter for photovoltaic micro-installation in central Poland. The purpose of this analysis was to estimate the real acceptable size of the NPR (Nominal Power Ratio) coefficient, defined as a ratio of maximum DC power of the inverter to the peak power of the PV generator, for PV micro-installations in central Poland.
