Abstract

These days, with the great development of electrical engineering sciences, the world is moving towards clean energy sources. Especially solar energy, there are many studies and research on PV panels, developing their productivity, increasing efficiency, and reducing losses. Remains a partial shadow problem for researchers, developers, and producing companies. In this research, a PWM solar inverter was designed to be powered through four PV panels. These four panels are connected in two ways: first, all panels are connected in series. The second way was these four panels splatted into two strings, each string contains two PV panels in series, and the two strings are connected in parallel to each other. After confirming the design of the inverter, the partial shadow effect has been tested with many scenarios. The voltage and current of each panel and the overall voltage, current, and power of the inverter have been measured in each one of the scenarios, and characteristic curves were drawn for each case. It will be explained in detail in these search paragraphs.

Keywords
