Not all that energy will end as heat. And the surface that it may cover won't be significant compared with the Earth one. And if it is, it may shadow enough surface to actually cool down Earth. In any case, it won't be worse than releasing a good amount of the captured solar energy in chemical form for millions of years in around a century.
