The 3V Solar Panel. A "3V Solar Panel" is the open-circuit voltage. In practice, the battery (1.2V) and the solar panel (3V, open circuit) will have to agree on where to operate. This is call the Q-point (Q = quiescent, latin for "being still" = equilibrium). In the case of a weak panel and a comparative strong battery, the battery will win.

Running at about 300-400 mA (a thirs of its rated power) and it’s super bright. Solar panel is a 7V 200mA+ (don’t have the datasheet – this is scrap from a broken gadget). Charges the batteries really fast. One of the brightest solar garden lights I know of! Very smart circuit – I love how the LED / CREE fades when I hide the solar panel.Get a Quote
The whole solar garden light timer circuit currently latches within this position until the next morning, when the rising positive voltage from the solar panel one more time resets the upper IC pin12 and the whole circuit. The circuit remains inactive until dark. The pattern consequently will keep repeating as described above.
