Net Metering and How You can
Make it Work for You
Net metering is the arrangement you can make with your power company. After installing a special net metering meter, you can sell your solar power back to the main grid.
The way it works is this: when you produce more solar power than you are using, your meter runs backwards. This is when your power company buys the power back from you. The power company then typically sells this power onto another customer (usually your neighbour) and you pay less for your power bill.
There are different types of net metering arrangements. The better ones allow you to either get credited if you make more power over a year than you use. Other arrangements will give you a 'floating credit' for one or more years. That net credit is generally not carried forward after a specified period. In other words, you don't get credited for a net annual excess of power.
