I would say neither. You see the reason the Lunar Eclipse made sense was because Werewolves are bound by the moon. In the first season and every other season after that it has been reinforced that the full moon gives power to the werewolves. It allows them to transform and gain and added strength.

But the sun has never been depicted as a power source for Werewolves,  I know that only Vampires are associated with the Sun and unless they invite another supernatural creature that gains more power from a Solar Eclipse I'd say this question is rather simple.

The moon is improtant to the Werewolves as it is to Natural Wolves.

The sun has never been depicted as such an important object.
