  • OK, but not for solar panel

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:

    Excuse me, for my english.
    Good construction. No other parts needed. Fully adjustable output voltage within the specified value.

    Cons:

    This solar panel can not be used because of low internal resistance to completely overload the solar cell, the solar cell voltage drops to 1-2 volts on which this module is no longer working, so there is no output voltage.
    The solar cells in current generator mode, the internal resistance is so high.

    OtherThoughts:

    If you would solve the use of solar panels, it would be a very nice gadget.

    Bottomline:

    Good, goog, but the Solar Power Supply?
