It is said that when Arceus made the sun, it buried tiny fragments of it in volcanoes around the earth, so that brave Gloom, Sunkern, Cottonee, and Petilil could use its energy in order to evolve. Yet just as the sun burns with enormous energy, changing in form over the years, so too did the Sun Stones; if unused for too long, they evolved into a pokemon called Solrock, capable of channeling much of the power of the Sun.
Solrock, because they contain pieces of the Sun itself, have become used in technology in more ways than most people can even imagine. In ancient times, they were used to magnify sunlight, reflecting the Sun's power in order to sink ships and water pokemon; most grass pokemon have this ability as well, but no grass pokemon is as capable of levitation or angling sunlight. Despite not being classified as fire pokemon, they are as capable as Magcargo of super-heating items (but with far better control), an ability which led to their use in alchemy to melt a variety of metals. In Fuchsia City, rumor even has it that they were used to grow a variety of poisonous plants in caverns and basements, for exposure to the outdoor sun carried a risk of revealing their secrets.
Perhaps most valuable of all (at least to Man), although the Sun itself runs on a timescale far longer than human comprehension, it is said that humans developed the concept of time by watching how shadows moved across a Solrock at rest. It was in emulation of this ability that the first sundials developed, and although modern clocks bear a greater resemblace to Hoothoot and use twenty-four hours instead of eight, one can still see the inspiration Solrock provided in their round shapes and the "hands" which resemble a Solrock's legs.
