Abstract: In the past two years, the Huanghua well has suffered from insufficient solar power supply due to the influence of cloudy and hazy, affected the normal data observation. Through calculation, it can be found that Huanghua well matches about 1 200 W of solar panels and three 150 Ah batteries, which can guarantee the normal operation of Huanghua well for six consecutive days in bad weather. Then we conducted a comparison test of power generation capacity between monocrystalline silicon solar panel and polycrystalline silicon solar panel, and a comparison test of solar panel power generation capacity under different erection angles. It is concluded that in north China, polycrystalline silicon solar panels are superior to monocrystalline silicon solar panels in terms of specific power generation. Unattended stations in north China can be powered by polysilicon solar panels. Adjusting the solar panel erection angle can change its generating power, but the effect is weak. In stations, solar panels can be set up in 45 °.
