First, let's dive into exactly what net metering is. In its simplest form, net metering is known as a form of "billing arrangement" in which energy overages that are produced by solar panels are tracked by an energy provider and then subtracted from a monthly energy bill.
Then, when your home-based solar system produces more energy than your actual home consumes, the overage or excess goes directly back into the grid. It's a win-win situation, really.
So, how does net metering work?
One way net metering works is when excess energy that your solar panels on your roof create, it gets measured by your energy company or provider. Then, a credit may be posted to your account with them and it can be applied to bills in the future.
Another way net metering works is when excess energy that your solar panels on your roof create, that gets measured by the electricity meter your humble abode comes with.
According to EcoWatch, "Modern power meters can measure electricity flow in both directions, so they tick up when you pull from the grid at night and count down when your solar panels are producing an excess amount of electricity."
So, regardless of which route you and your family take, you'll ONLY be responsible for your "net consumption" which is the difference between total consumption and generation.
