  • "Joule Thief" Circuits, crude to modern...

    From the circuit iIt looks like the ic relies on the input voltage from the solar panel being less than the forward voltage of the led. You will therefore need a panel with a maximum voltage around 2.5V. You would be able to increase the capacity of the solar panel by connecting multiple 1.5V solar cells in parallel.
