Shine Drop rate can go as high as +75% from what I read somewhere. Solar damage has no upper limit to my knowledge, indeed Dogwood after evo adds 40% damage to the blast.

Translated (Read: Google Translate) from the jap wiki for Cactace "in combat, Shine Crystal drop rate of party members is 30% rise ※ rise up to a maximum of 75% in combination with other abilities"
