It's an apples-to-oranges comparison. The idea here is replacing solar usage with kinetic energy in certain applications so fewer devices need an external power source and therefore wiring. It would also reduce grid use (by a minuscule amount), but I'm assuming the solar comparison is solely because both produce a DC current.
