Photovoltaic power generation is a technology that directly converts light energy into electric energy by using the photovoltaic effect at the semiconductor interface. The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. Photovoltaic power generation is mainly composed of solar panel (module), controller and inverter, and the main components are composed of electronic components. After the solar cells are connected in series, they can be encapsulated and protected to form a large area of solar cell modules, and then combined with power controllers and other components to form a photovoltaic power generation device.
