What is the difference between a net meter and a bidirectional meter?
Net Metering Policies*: Instead of receiving a credit for the power and being able to use that credit later, bi-directional metering pays a lower than retail rate, called avoided cost, for any power that is sent back to the utility.
How do I know if my meter is bidirectional?
Bi-directional meters have three display screens. One is a test screen where all lights are on. The second shows power coming in from the grid, and the third shows power going out from your solar into the grid. Typically, the screen notation with 001 shows power coming in, and 002 shows power going out.
What is dual metering?
Under an alternative billing policy, sometimes called “dual metering” or “net purchase and sale metering,” utilities install a second meter at the customer site and pay a different rate for solar electricity exported to the grid, generally a wholesale avoided cost rate.
How does a bidirectional meter work?
The term bi-directional metering refers to the fact that the meter can measure the flow of electricity in two directions. If the customer generates more electrical energy than is used from the utility electrical system, then the customer receives a kWh credit, which is applied to future bills.
What is a bidirectional net meter?
A bi-directional meter works by measuring energy in two directions; how much energy you consume from the grid, and how much excess energy you export back to the grid. It is the piece of equipment that allows you to receive feed-in tariffs or payments through the Renewable Energy Buyback Scheme (REBS).
Can a digital electric meter run backwards?
When your PV system makes more power than your home uses, your electrical service meter reverses — you can watch it go backward. However, utilities have moved to digital metering. If you do have an old analog meter, the utility will replace it with a new digital one a few days to a month after your system is installed.
Do smart meters run backwards?
Many people want to know if and how the power meter will run backwards after a solar power system is installed, so the following article was written to explain the answer to this commonly asked question. The short answer is yes, your power meter can spin backwards when you go solar.
Why is the dual meter used?
Another system is dual metering. Two separate unidirectional meters are used per consumer. One meter records the total energy received from the grid, and the other records that fed in to the grid. This type of metering is useful when different rates apply to energy provided by grid and that by the consumer.
