Net Metering vs net billing
When looking at solar, how your utility handles energy matters just as much as the system itself.
Two common structures are net metering and net billing. They sound similar, but they work differently and can change how a system is designed.
What These Terms Mean
Both net metering and net billing deal with what happens to extra energy your system produces.
During the day, solar systems often produce more energy than a home is using. That excess energy is sent to the grid.
What you receive in return depends on how your utility handles it.
Net Metering
With net metering, extra energy sent to the grid is credited at or near the same rate you pay for electricity.
In simple terms:
You send energy to the grid during the day
You receive a credit for that energy
You use those credits later when your system is not producing
The grid acts almost like a battery.
Because of this, systems under net metering are usually designed to offset as much of your usage as possible without needing storage.
In many cases, a battery is not necessary from a financial standpoint, though some customers still choose to add one for backup.
Net Billing
Net billing works differently.
Instead of receiving full credit for the energy you send to the grid, you are paid at a lower rate. At the same time, electricity you pull from the grid is still billed at the normal rate.
In simple terms:
You send energy to the grid at a lower value
You buy energy from the grid at a higher value
Because of that difference, sending energy back to the grid is less beneficial.
Where Batteries Come In
This is where system design starts to change.
Under net billing, it often makes more sense to store extra energy instead of sending it to the grid.
A battery allows you to:
Keep more of the energy your system produces
Use that energy later when rates are higher or solar is not producing
In many cases, this makes batteries more valuable under net billing than under net metering.
Why This Matters
The way your utility handles energy directly affects how a system should be built.
Under net metering, systems are often designed for full offset
Under net billing, systems may be designed with storage in mind
The goal is to use as much of your own energy as possible, especially when export rates are lower.
Changing Landscape
Net metering is becoming less common.
Many utilities are moving toward net billing or other structures that reduce the value of exported energy.
Because of this, batteries are becoming more relevant in more areas.
That does not mean every system needs one, but it does change how projects are evaluated.
How We Approach It
We look at how your local utility handles energy first.
From there, we design the system based on what actually makes sense for your situation.
If net metering is available, that may shape the design one way. If it is not, we look at how storage or other adjustments can improve the system.
Net metering and net billing both affect how solar systems perform over time.
The main difference comes down to how exported energy is valued.
From there, the system is built around that structure to make sure it works the way it should.
