To put that in perspective though, to create a sphere surface just 2 solar radii away from the center of the sun, you would need to launch ~1.3*10^16 kgs worth of Sputniks into orbit (assuming sputnik would have been enough to convert and transmit sunlight into electricity. This is just the weight of the satellites themselves - add launch vehicles and the placement vehicles, and you're looking at numbers that start to rival the weight of mountains.
