Problems solved by technology

[0003] Since photovoltaic power stations are generally built in remote areas, the geographical environment and natural conditions are relatively harsh, and decentralized maintenance and manual monitoring cannot be carried out in the traditional way in the past. It is very difficult and cumbersome, requires a lot of manpower, material resources and financial resources, and the work efficiency is low and the work quality is poor
