Sunlight Medal description:

"This faintly warm medal, engraved with the symbol of the Sun, is the ultimate honour, awarded to those who summon the Warrior of Sunlight and complete a goal. The symbol represents Lord Gwyn's firstborn, who lost his deity status and was expunged from the annals. But the old God of War still watches closely over his warriors."

So the Symbol of the Sun represents the Gwyn's firstborn, and Solaire carries it on his armor. I think that's basically as far as the theory goes.
