1. A system for operating with a rechargeable battery, the system comprising a solar photovoltaic panel, a thermometer and extension conductors coupled between the thermometer and the photovoltaic panel, wherein:

  • the thermometer includes a thermometer mechanism responsive to temperature and a control circuit;

    the control circuit includes a recharge circuit, an illumination circuit and at least one LED disposed to illuminate the thermometer;

    the recharge circuit is coupled to the solar photovoltaic panel through the extension conductors and operable to recharge a rechargeable battery when the photovoltaic panel produces a voltage greater than a predetermined threshold;

    the illumination circuit is coupled to the rechargeable battery and to the at least one LED, and is operable to energize the at least one LED at a predetermined time; and

    the extension conductors are sufficiently long that the thermometer mechanism is capable of being disposed in a shade area for at least part of the daylight hours while the solar photovoltaic panel is disposed in a sunny area during daylight hours.
