Net Energy Metering In Action
The meter photo shows Net Energy Metering in action. Notice the arrow pointing left and the negative number showing that 4.960 kilowatts of energy was being sent to the grid at that moment. By sundown that day (December 29, 2015), a total of 31.82 kWh was generated by this particular rooftop solar system.
During daylight hours that day, this rooftop solar system produced more energy than was consumed by the household over the full 24 hour period.
After sundown the residence was able to draw energy back from the grid without cost, still leaving surplus energy on the grid. Net energy use on this day was less than the energy produced.
