  While the installed photovoltaic capacity grows to a terawatt scale, effects
of global climate change unfold. The question arises, how a changing climate,
and especially raising temperatures, will affect the performance of PV
installations in the future. In this paper we present an estimate of the
reduction in energy yield for silicon PV installations due to global warming in
the year 2100. Using IPCC global warming scenarios and published temperature
coefficients for todays silicon PV panels, we project median reductions in
annual energy output of today's silicon solar panel of 15kWh per kWP, with
reductions up to 50kWh per kWP in some areas. Higher efficiency cells and
advanced cell and module architectures can significantly reduce these losses.
Cell concepts with higher voltage are particularly effective in reducing
temperature induced losses.
