The positive electrode of a solar panel. In solar power generation system, PV2+ refers to the positive electrode of the solar panel. The solar panel is part of the solar energy production system. It mainly consists of solar cells, aluminum frames, surface glass, junction boxes, etc. them, the positive and negative electrodes of the solar panels. The terminal is the PV terminal. There are three terminals in the junction box, namely two PV terminals and one N terminal. The N terminal is the negative pole and the two PV terminals. are respectively the positive pole and the negative pole.
PV Cell: Photovoltaic solar cell (called photovoltaic cell) is used to convert light energy from the sun directly into electrical energy. At present, ground-mounted photovoltaic systems use a large number of silicon-based solar cells, which can be divided into s-cells.olars in monocrystalline silicon, polycrystalline silicon and amorphous silicon. In terms of overall performance such as power conversion efficiency and lifespan, monocrystalline silicon cells and polycrystalline silicon cells are superior to amorphous silicon cells.
