A solar array makes the earth less reflective by a fixed amount, for as long as the array exists.
Every unit of fossil fuel we burn makes the earth permanently less reflective (or at least something on the order of 100 years). You could compare a 1GW solar array (for its lifetime) to a 1GW coal plant running for x days, though I don't have the value of x.
