Discussion on Problems and operation and maintenance of distributed photovoltaic power stations in Tibet

Due to the vast area of Tibet, where farmers and herdsmen live scattered, and the construction sites of solar distributed photovoltaic power stations are relatively scattered, which makes the operation and maintenance of the system more difficult. At the same time, due to the lack of practical experience of technical personnel, even if there are problems in photovoltaic power stations, they can not get timely feedback and solution. Over time, many distributed photovoltaic power stations are forced to be abandoned because of no maintenance and repair. These phenomena also restrict the application of photovoltaic power in Tibet to a certain extent. Based on the field investigation of distributed photovoltaic power stations in Tibet, this paper finds out the common faults and existing problems of photovoltaic power stations, analyzes the causes of the failures, and puts forward suggestions for operation and maintenance. The purpose of this paper is to build a solar distributed photovoltaic power station with high reliability and easy maintenance in Tibet, so as to provide a certain scientific basis for the existing photovoltaic power station and the later construction of photovoltaic power station.
