In the framework of projects carried out in partnership with the ATAMOSTEC institute in Chile, the CEA at INES is identifying a procedure for accelerated ageing of photovoltaic panels in a desert environment.
Desert regions represent between 20 and 36% of the Earth's land area, depending on the definition criteria. Irradiance is high and constant, and land use conflicts are very limited. The Atacama Desert in Chile is a prime location for the installation of solar photovoltaic systems. This high potential is due in particular to its favorable exposure and low temperatures.
However, the extreme climatic conditions of deserts raise the question of the durability and bankability of photovoltaic systems mainly developed for temperate climates.
