What Is Net Metering? How Solar Owners Get Credit for the Power They Generate


If you've ever looked into solar and found yourself nodding along until someone mentioned "net metering" — and then quietly nodded less — you're not alone. It sounds technical. It isn't.
Net metering is simply the billing arrangement that determines what happens to solar power you generate but don't immediately use. Understanding it takes about five minutes, and it has a direct bearing on how much money a solar system actually saves you.
Here's how it works.
The Basic Idea
When you install solar panels, they generate electricity during daylight hours. Some of that electricity gets used by your building in real time — lights, HVAC, equipment, whatever is running. But solar panels don't throttle their output to match your demand. On a sunny afternoon when your building isn't using much power, your panels may be producing significantly more electricity than you need.
Without net metering, that excess power would simply be wasted or sent to the grid for free.
Net metering changes that. According to the Solar Energy Industries Association, net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. When your panels produce more than you're using, the surplus flows out to the utility grid and your meter runs backward. When your panels aren't producing enough — at night, on cloudy days, in winter — you draw from the grid and your meter runs forward.
At the end of each billing period, you pay only for the difference between what you consumed and what you generated. Hence the name: net metering.
What "Credits" Actually Means on Your Bill
One thing that trips people up: net metering credits are not cash payments. You won't receive a check from your utility because your solar panels had a productive month.
Instead, as EnergySage describes it, you're only billed for your "net" energy usage — consumption minus production. Credits from months where you overproduce roll forward and offset your bill in months where you underproduce. For most properties, this means racking up credits during the long sunny days of summer and drawing them down during shorter, cloudier winter months.
What makes traditional net metering financially valuable is the rate at which credits are calculated. Under a true net metering arrangement, credits equal the retail electricity rate — the same rate you'd pay to buy electricity from the grid. That one-for-one exchange is what makes the math work well for solar owners. However, some states are shifting to a model where the credit rate is less than one-to-one. Rhode Island is a current example: systems installed before April 2023 receive credits at the full retail rate, while new installations receive credits at 80% of that rate.
How This Plays Out for a Commercial Property
For a business or commercial building owner, net metering works the same way in principle — but there are a few things worth understanding that don't apply to the residential context.
First, the upside: commercial properties tend to use a lot of electricity during the day, which is exactly when solar is producing. A well-sized system on a commercial rooftop can offset a substantial portion of daytime consumption directly, and send the excess to the grid as credits for later use. The alignment between when solar produces and when a business operates is genuinely favorable.
Second, the limitation: net metering credits offset the energy consumption portion of your utility bill, but they don't touch demand charges. Demand charges are a separate line item on most commercial electricity bills — a fee based on your single highest moment of peak power draw in any given month. These charges can account for 30–50% of a commercial electricity bill and are entirely unaffected by net metering. If demand charge reduction is a priority, that's where battery storage becomes relevant — but that's a separate conversation from net metering itself.
Third, system sizing matters. Most net metering programs, including Rhode Island's, require that a system be sized to meet on-site consumption rather than to generate large surpluses. In Rhode Island — where Newport Renewables is based — the state's net metering policy allows customers to generate up to 125% of their on-site consumption during a billing period, according to the Rhode Island Office of Energy Resources. Designing a system well beyond your actual usage is generally not permitted, and credits for significant overproduction are typically reconciled at lower rates anyway.
What This Means in Practice
Net metering is one of the two or three factors that most determine whether a solar system delivers strong financial returns.
A system that's well-sized for your consumption, in a state with a favorable net metering policy, can offset a very high percentage of your annual electricity costs. Credits from productive months cover consumption during slower ones. Over a 25-to-30-year system life, that adds up to a significant number.
The important thing for any property owner or business to understand going in: what your state's current policy is, whether any changes are planned, and how your system should be sized to work within that policy. A good solar installer will walk you through all of this before anything gets designed or contracted.
