A concave mirror would focus all of the light from a wide area into a single point. What you've created there is a giant space laser. One that only works at night because you need the sun on the opposite side of the Earth to reflect it.

Also all of the previous problems about it needing to be massive, or close to the Earth and moving faster apply.
