@eddz99: And at what point in the series was this supposedly exclaimed, since I believe it to be an attack generated by the user?
Even the DB Wiki, which you were boasting about last night, makes no mention of the attack coming from the sun (details below come from wiki as of the time I read it, in case someone edits the article):
The Solar Flare is performed by the user placing their hands close to the center of their face with the fingers spread toward their eyes. The user then calls out the name of the technique, which provokes a white light to fire out and blind everything watching except the user, since they are projecting the light. This technique is defensive rather than offensive, and is mainly used as way to gain the upper hand, or in order to make hasty retreat, or to set up for a more complicated attack without fear of interruption.
Despite the simplicity of the attack and its "old" nature, the technique is still deemed extremely effective against some of the most powerful foes ever encountered by the Z Fighters because of it nature. Due to it being simply a flash of light, it works regardless of any gap in power between the user and the target. This technique is rendered useless if the opponent is wearing sunglasses, as evident in the 22nd World Martial Arts Tournament when Tien Shinhan uses the technique against Jackie Chun, affecting him while Master Shen and the World Tournament Announcer are unaffected by the flash. In the finals of the same tournament, Goku borrows Master Roshi's sunglasses to prevent Tien's Solar Flare and he is even capable of hitting Tien during the execution of the technique. This is also proven in the 23rd tournement when Goku uses the technique during his fight with Tien, which effects everyone but Master Roshi and the announcer.
The technique is used by Tien Shinhan during the 22nd World Martial Arts Tournament (the Solar Flare is one of Tien's signature moves) and later on by Goku, Krillin, and Cell. Also during the 22nd World Martial Arts Tournament, Krillin uses a personalized version called Taiyōken Hansha in his match against Goku. During the 23rd World Martial Arts Tournament, Goku uses the Solar Flare on Tien Shinhan himself, who is using the Multi-Form technique. Goku uses it again during his fight with Vegeta in the latter's Great Ape form, so Goku could have extra time to prepare his Spirit Bomb. During the battles on Namek, Krillin used the Solar Flare to blind Dodoria who is chasing him, after he and Gohan rescued Dende. Krillin performs this a little differently when he uses it on Dodoria. However, it still produced the desired result. Krillin later uses it again against Second Form Frieza.
After the Frieza Saga, it is used several times by Cell to escape the Z Fighters and helps him in his mission to absorb Android 17 and Android 18. Krillin uses it on Cell in an attempt to slow him down in order for an airplane containing two survivors of Cell's attack at a town to escape, although Cell manages to catch up to Krillin upon liftoff and subsequently plow him through the plane, almost absorbing him had it not been for the Z Fighters arriving at the general vicinity.
Master Roshi uses the Solar Flare in Dragon Ball Z: Atsumare! Goku Warudo. In the Great Saiyaman Saga, it is used by Goku when he fights Arqua in the Other World Tournament. In the Baby Saga of Dragon Ball GT, Super Saiyan 4 Goku uses the Solar Flare to temporarily blind Golden Great Ape Baby so he could gather energy from Gohan, Trunks and Goten. The solar flare normally does not do any damage, but Nuova Shenron has a special lens that can amplify sunlight to lethal levels. When Goku shot a Solar Flare through this lens, it did a considerable amount of damage to Nuova. Later in the Shadow Dragon Saga, Goku uses the Solar Flare on Omega Shenron, but it did not even phase Omega. It is the only time where the Solar Flare failed to halt an enemy.
