With exception of the manufacturing of the facility and equipment, Yup. BUT, it potentially does have environmental effects as to the weather, absorb enough solar energy and keep it from hitting the Earth, and there is a potential cooling effect from the prevention of the solar to thermal energy conversion from the sun to the ground to the air.

other way around, really.  since the panels would reflect less energy
back out into space (than the ground below them would have) , *more* of
the sun's daily dose would be absorbed by "the surface of the planet". 
it ends up being distributed as heat when the "stored" energy is used.
