When it comes to renewable energy systems like solar panels, understanding how excess energy is handled can make a big difference in savings and planning. Two common mechanisms—net metering and net billing—are used to manage this energy. Here, we’ll break down the differences, advantages, and considerations of each to help you make an informed decision.
What is Net Metering?
Net metering allows homeowners or businesses with renewable energy systems to send excess electricity they generate back to the grid. For every kilowatt-hour (kWh) of energy exported, the meter runs backward, effectively crediting the customer at the retail rate of electricity.
Key features of net metering include:
- Retail Rate Credit: The electricity exported is valued at the same rate as electricity purchased from the utility.
- Monthly or Annual Reconciliation: Any surplus credits can typically roll over to future bills within a billing cycle.
- Customer Simplicity: Easy-to-understand bills and direct savings.

What is Net Billing?
Net billing also allows customers to send excess energy to the grid. However, the energy exported is credited at a pre-determined rate, often lower than the retail rate. Customers are then billed separately for the energy they consume.
Key features of net billing include:
- Wholesale Rate Credit: Credits for exported energy are typically based on the utility’s avoided cost or wholesale market rates.
- Separate Billing: Customers pay for the electricity they use, minus the credits earned for their exported energy.
- Flexibility in Energy Markets: Net billing often aligns with the true cost of energy production and distribution.

Comparing Net Metering and Net Billing
| Aspect | Net Metering | Net Billing |
|---|---|---|
| Credit Rate | Retail electricity rate | Wholesale or pre-determined rate |
| Reconciliation | Monthly/annual rollover | Separate energy purchase and crediting. Can be monthly. |
| Customer Savings | Higher | Moderate to lower |
| Utility Perspective | Less cost recovery from participants | Aligns better with utility cost recovery |
Which One Is Better for You?
The choice between net metering and net billing depends on various factors, including your location, utility policies, and energy goals. In states or countries where retail electricity prices are high, net metering may offer greater savings. However, net billing’s alignment with wholesale market rates often makes it more sustainable for utilities.
