Well as you can see from the numbers, a 5 degree increase in temperature would mean a 2,5% decrease in output.
As far as I know, the modules are usually not cooled. There are however modules with integrated water cooling, which can also be used to generate heat output which you can turn into energy.
But this is only for photovoltaic modules. There is other types of solar energy, for example molten salt.
/edit: to clearly answer your question: it doesn’t matter that much to solar power in general.
