ELECTRONIC METER PACKAGE WITH SOLAR POWER

Most all electronic meters include a low voltage unregulated supply that is fed from the AC line.  By adding a solar panel to the meter cover the solar panel output can be fed into the unregulated supply voltage to displace AC current draw whenever there is adequate sunlight.  This simple concept of embedding a small solar panel (approximately 1 watt) into the cover of every electric meter can make the meters revenue neutral throughout their life.

As solar panel technology continues to gain efficiency in extraction of energy from the sun, the top surface of the electronic meter will allow the generation of more power than the electronic meter can utilize.  The excess power can be fed into super-capacitors for storage and use during night time hours or the excess energy may be fed back into the power grid.

This disclosure envisions the development of a low cost converter that can take the excess energy output of the solar array and feed it into the AC line.  Because of the converter source current will only be a few milliamps into the AC service voltage, the converter technology will be low power and potentially integrated into an off line switcher as an equivalent of a “power converter/power source” pair.  When this technology is applied to 10s of millions of electronic meters the production costs for the converter/inverter will drop significantly.
