What is Net Metering?
Net Metering is a system that gives solar energy owners credits for the power that they add to the grid. When solar panels produce excess power, that power is sent to the grid. And this power can be ‘taken back’ when the solar plants are not functioning – example, during the night. When a unit of solar energy that has been ‘net metered’, the bi-directional electricity meter will run backwards. Customers are billed only for the ‘net’ energy use.
How does Net Metering Work?
The solar power systems are connected to the utility grid via the customers’ main service panel and meter and, when generating more power than is needed at the site, return excess electricity to the grid through the power meter, reversing the meter from its usual direction. Thus, a bi-directional meter is needed to avail net metering. Since the meter works in both directions (i.e. bi-directional meter)– one way to measure power purchased (when on-site demand is greater than on-site power production), and the other way to measure power returned to the grid – the customer pays the “net” of both transactions.
