It could only ever increase by the surface area of the satellite lens things. It'll be a rounding error compared to the surface area of Earth (or compared to the effect of greenhouse gasses over the time period you're setting up these things).

You jest but if one sattelite can be used to focus light onto the earth, it can also be used to focus it away from it, evening it out.
