Bi-directional electric meter on panel box, 2016
Since Edison's day, electrical meters have measured the flow of current in one direction only -- from power plant to user. Customers can then be billed for the amount of electricity they use. Measuring current that flows in both directions requires a bi-directional or net meter like this one. It runs forward when the user draws power from the electric lines and backwards when solar panels make more power than the building is using. This feature can lower the customer's monthly electric bill and reduces the need for new power plants to meet growing demand. |
