Nooo, Solars are about expression of Virtue. Their charms help them reach greater heights through sheer skill (and sometimes blast things with sunlight). They exalt, however, from expressing that which is the other aspect of the Unconquered Sun. Conviction for being unwilling to fall, Valor for facing overwhelming odds, Compassion for trying to save a loved one, Temperance for... keeping your cool in stressful negotiations? Nobody exalts as a Solar by doing everyday training.
