In arid and hot areas, sandstorm, high temperature, high radiation, dust and so on will greatly affect the power generation capacity of photovoltaic power generation system, and push up the operation and maintenance cost of the power station. In Qatar, Morocco, the United States and many other regions have carried out research on the durability and reliability of photovoltaic systems in the "dry hot desert" climate, so as to help the photovoltaic industry better predict the life of photovoltaic modules in the "dry hot desert" climate, improve the selection of materials used for photovoltaic modules, and help photovoltaic manufacturers understand their product life guarantee.

As early as 2011, the Qatari government proposed to establish a photovoltaic test site to assess the impact of local climate conditions on the photovoltaic system and help financial investors determine the life and performance of photovoltaic power plants. More than 60 photovoltaic modules have been studied for six years by qeeri and Fraunhofer Solar Energy Research Institute in the outdoor test field of Doha Qatar science and technology park.
