Solar power is a key strategy to enhance the energy structure. This study analyses the PV power in domestic railway stations, compares independent and grid-connected systems, and solar battery systems. It then suggests two grid-connected systems using monocrystalline silicon panels and amorphous silicon thin film panels. The second plan is ultimately chosen, and engineering practice confirms its correctness and sanity. This is done while taking into account economic, energy-saving, environmental protection, and aesthetic concerns.

In order to reduce the severe energy crisis and environmental damage, this is crucial. Since the energy crisis of the 1970s, every nation in the world has focused more on the development of PV power generation. Examples include the Million Solar Roofs Initiative of the United States, the Sunshine Programme of Japan, the Million Solar Roofs Programme of Germany, and the Bright Project of western China's provinces without electricity[1]. A type of optoelectronic device known as a solar battery uses the PV Effect to convert solar energy into electrical energy. The PV effect, which occurs when a device is exposed to light and produces voltage in the cell between its electrodes and electrolyte[2], was initially identified in 1839 by the French experimental scientist Edmund Becquerel. Currently, the world's new solar battery research and development is concentrated on two areas: efficient crystalline silicon solar batteries and various forms of thin film solar batteries. The conversion efficiency of efficient silicon solar batteries is close to 25%, and that of efficient polysilicon solar batteries is now near 20%. Better low-light performance and relative affordability are thin-film solar battery advantages, but its major drawbacks are low efficiency and light-induced deterioration. 2. PV APPLICATION MODES The power generation capability is unstable due to sunset, bad weather, and other natural limitations. The independent PV system and the grid-connected PV system are the two application modes for solar PV systems. (a) Independent PV Systems The solar component, controller, battery, inverter, and other components make up the independent PV system. Figure 1 depicts the independent PV system's structure. The power unit of the solar component can convert solar energy into direct current[3]. The DC electric energy from the solar component is stored in the battery, which is an energy storage unit. The controller's primary responsibility is to control battery charge and discharge. And an inverter will convert D.C. into AC in order to supply an AC load. Independent power systems' primary flaws are their extremely low storage capacity, increased volume, increased weight, and expensive battery cost. It typically has a 3–5-year operational life and substantial maintenance costs. Battery recycling after damage is another issue.
