    Under the sun the hot glue not resist and you need two capacitor on the circuit,before and after transistor!!.with this solar panel you can not charge a must add a battery with charge regulator....the current out to lm7805 is too low for this usage.....with this solar panel. some phone need 1A or above......

    Don't worry this small pane, will deliver 200-300mA if the sun is bright.

    The 7805 is not suited for solar panels, look for the data sheet, it needs 7V to regulate to 5 v. Ther are special ICs for solar panels because they have a most effektive working point.

    If you must buy the panel for a real price better look for a special Regulator which get all the juice from the panel.

    And hot gluing the 7805 to the panel? He gets away with that because the Panel is to weak to heat the 7805 up.
