Photovoltaic installers may be tired. Most photovoltaic power plants are built far away from human habitation. Photovoltaic installation workers may have to work outdoors for a long time, endure the scorching sun, endure the wind and rain, and even face the high temperature weather in some areas. In addition, photovoltaic installation needs to be carried out according to certain processes and standards, and the workload and difficulty of installation workers will also increase.
