Net metering is a law in New Jersey and in most states throughout the nation that allows an electric generator to export power to the grid provided the electricity is compatible with the grid power. Grid tied solar electric are permitted to export electricity to the grid whenever the system is generating more electricity than is being consumed by the facility. Solar electric systems that qualify for the New Jersey Clean Energy Program's SREC program are "grid connected" and subject to net metering regulations.
When a solar electric system is generating more power than is used by the facility, the surplus electricity is sent to the utility, spinning your meter backwards and accumulating a credit. The credit will be reduced as electricity is taken from the grid. If at the end of a billing year, the solar system has produced more electricity than was used, then the utility will pay for the surplus amount.
Solar systems that are connected to the grid must automatically shut down should there be a loss of power on the grid. Electricity cannot be exported to the grid should repairs be in progress.
Note: Solar electric production occurs during midday, reducing the more expensive "on-peak" electric rate that may be as high as $.27 per kWh.
This graph illustrates the typical electric usage of a home located in New Jersey. The homeowner's consumption, high during winter months due to lighting expense and higher in summer months with air conditioning.
The solar production graph illustrates the amount of electricity generated from a solar electric system throughout a year. The major amount of electricity being generated during the summer months.
The graph shows the resultant electrical consumption for a house with a solar system that closely matches the annual consumption of the house. The consumption is reduced during summer and winter, however in spring and fall, the solar system may produce more than is consumed by the facility resulting is credits being accumulated for use during following months.
