  This paper presents the first study of the long-term impact of climate change
on photovoltaic potential in South America. This region has great potential for
implementing renewable energy, mainly solar energy solutions, due to its high
solar irradiance levels. Based on the Coordinated Regional Downscaling
Experiment (CORDEX) for the South American region, we estimate how climate
change could affect photovoltaic power potential by the end of the century. The
evidence suggests that photovoltaic potential could have a maximum decrease of
$15\%$, and a maximum increase of $7\%$, primarily due to changes in solar
irradiance of different zones. Furthermore, it is observed that regions with
increased temperature also show increased solar irradiance levels, which could,
to some extent, compensate for the losses caused by the rise in temperature.
Therefore, photovoltaic production in most of the territory will not be
negatively affected.
