I also like "Soliel."
"Sol", Spanish for "Sun" or "Soleado" for "sunny"
"Saul"
"Sonny" for a boy
"Amarillo", "Amaryllis" playing with "yellow" in Spanish
"Sunflower"
"Dante"
"Surya" a Hindu Sun god
"Liza" a West African Sun god
" Lugh" a Celtic sun god ("luke" I think would be the pronunciation)
"Mithras" a Persian sun god
The south american sun gods are difficult to spell and pronounce, but would be appropriate:
"Huitzilopochtli" (Wheat-za-pocked-li) or "Tonatiuh" (Tawn-at-ee-uh) (My best guess at the pronunciation, I couldn't find a definitive reference quickly).
