When you think of a solar energy system, you probably think of solar panels that are placed on your roof to convert the sun’s energy into electricity for your home or business. But there’s more to solar energy systems, including meters that tell you how much electricity your system is generating, how much energy you’re using, and how much energy you’re purchasing from the utility company.
These meters are often overlooked components of solar energy systems, but understanding what type of electric meters are used with solar panels can help you decide on a solar energy system. Let’s take a look at the types of electric meters that are available, and that you might need for your solar energy system.
Utility Meters
All owners of a grid-tied solar system will need a bi-directional utility meter to keep track of the electricity their system is taking from and transferring to the grid. So when you install solar panels, you will most likely get a meter installed during the process, which will show how much power is coming in from the grid, as well as how much power is going out from your solar into the grid.
Net Meters
Unlike bi-directional utility meters, net meters do not measure how much energy you are producing, or how much you are consuming from the grid. This type of meter actually measures the difference between the two, or the “net usage” of your solar energy system. And if your system is producing more energy than it’s using, you can actually see your meter run backwards!
PV Meters
Photovoltaic meters, or PV meters, are used to measure how much electricity your solar system generates. These are considered one-directional meters because they only measure power that is transferred to your solar energy system and not vice versa. They are accurate in measuring usable electricity, so can be used for solar renewable energy credits (SRECs) if you live in a state that has an SREC market. SRECs are credits you get from your utility company for every thousand kilowatt-hours your system produces. These meters are not necessary to install unless you plan on selling your SRECs.
PV meters need to be connected to the internet so it is possible to monitor your solar system’s production. You can then connect your meter to your computer or smartphone and read the meter instead of having to walk outside and look at the meter mounted on the wall.
Consumption Meters
These meters are not necessary but they are useful in informing you exactly how much electricity you have used, including the electricity that is used directly from your solar energy system. They also measure the electricity that is pulled from the utility company. A consumption meter can be useful for determining your exact electricity usage, so you can make sure that your solar system is meeting your electricity needs and isn’t falling short.
