    A linear regulator is very wasteful of precious solar energy. A buck converter would help. Why do you think you need the capacitors, and what do you mean by "fet"?

    Welcome to the forums!

    BTW, we're kinda like Jeopardy: we need that in the form of a question.

    Whichever way you look at it; the solar cell is the only source of energy in this parts list and connecting stuff to it will not magically introduce more energy.
    So what's new, Sreve?

    linear regs are cheap and i am familiar with them. buck and other regs are fine, i am asking for suggestions to improve it, fet=field effect transistor to isolate caps from over charging.

    not looking for magic energy. caps are for storage when no sun
    i am disabled, can only email with many typo's.

    Why not charge a battery, it would be more useful for most applications?

    What are you trying to achieve here?

    Ditto on the questions above. A battery is a "voltage regulator" all by itself and is far superior to a capacitor for storing energy. Lower cost, lower volume.

    agreed.
    A battery of suffciently large capacity will absorb every electron produced by the solar panel, minus the unavoidable waste heat and chemical conversion costs. adding anything else just increases the losses. end of story.
    Now, what are you wanting to accomplish with the additional circuitry?
