Photovoltaic power generation mainly consists of three major parts: solar panels (modules), controllers, and inverters, and the main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device. The photovoltaic power generation system has no mechanical moving parts, is pollution-free and noiseless, and has a long working life. Although it has a lower efficiency than the solar thermal power generation system, due to its particularly simple system structure and unique advantages - modular structure, it is suitable for power production of any scale, from large central power plants to small private residential power supply.
