If you are wondering how does net metering work in Ontario, the short answer is this: your rooftop solar system feeds electricity into the grid when it produces more than your home uses, and your utility credits that surplus against the power you draw later. Net metering suits homeowners with a grid connection who want to offset daytime and seasonal usage without battery storage. Homeowners who expect to produce far more than they consume, or who want to be paid for exports at a set rate, should look at a different arrangement, such as the Feed-in Tariff style structure that has been used historically, though availability has changed over time.
Quick Comparison: Net Metering vs. Other Ontario Solar Compensation Options
The table below compares the main ways an Ontario homeowner with solar can be credited for electricity sent to the grid. Program details can change, so confirm current rules with your local distributor before committing to a system size.
| Criterion | Net Metering (Ontario) | Full Export Compensation (Feed-in style) |
|---|---|---|
| How exports are credited | Surplus kWh offsets future kWh drawn from the grid | All exported kWh are paid at a contracted rate |
| Best fit | Homes that want to match annual usage | Systems built mainly to sell power |
| Self-consumption value | High, since each home-used kWh avoids a purchase | Lower incentive to use power on site |
| Billing complexity | Low to moderate; credits appear on the regular bill | Moderate; separate payments and contract terms |
| Battery compatibility | Works with or without storage | Storage can be added, but economics differ |
| Typical homeowner profile | Owner-occupiers sizing for their own load | Owners sizing for maximum output |
How the Credit System Works Step by Step
Understanding how does net metering work in Ontario starts with the meter. A bidirectional meter records electricity flowing in both directions. When your panels produce more than your home uses at that moment, the excess flows out to the grid and the meter spins backward. When your home needs more than the panels supply, such as during evenings or cloudy weeks, power flows in from the grid as usual.
- Your inverter converts DC output from the panels to AC power for your home.
- Any surplus leaves the house and enters the local distribution system.
- The utility records exported kWh and imported kWh over the billing period.
- Exports are netted against imports. If you exported more than you imported, that surplus carries forward as a credit.
- Credits are applied to later bills, usually over a set period, with the remaining balance handled under the program rules.
The practical effect is that a sunny June can offset a dark December, provided the year balances out. This is why the design target for most homes is an annual energy match rather than a match for every hour.
What counts as a credit
In most net metering setups, one kilowatt-hour exported earns one kilowatt-hour of credit. That one-to-one relationship is simpler than paid export schemes, but it also means the value of each credit equals the value of each kWh you would otherwise buy. Owners often report that this makes self-consumption the most valuable use of solar output, because every kWh used on site avoids a purchase entirely.
Winner by Criterion
Winner for Simplicity: Net Metering
For most homeowners, net metering is simpler to understand. You do not need to manage separate export payments, track a contracted rate, or reconcile two streams of income. The credit appears on the same bill you already receive. If you want low administrative friction, net metering wins this category.
Winner for Self-Consumption Value: Net Metering
Because each exported kWh offsets a future kWh you would have bought, net metering rewards homes that use their own power. Run the dishwasher, heat water, or charge an EV during daylight, and the solar output is worth its full retail-equivalent value. Pure export schemes can pay more per exported kWh, but they give little reason to consume power on site.
Winner for Large-Scale Producers: Full Export Compensation
If you plan to build a system much larger than your household load, exporting most of what you generate matters more than offsetting your own bill. In that case a per-kWh export contract can be more useful than net metering, since surplus credits accumulate and may not be fully used. Check the rules for any credit expiration or true-up before choosing this route.
Winner for Storage Owners: Tie
A home battery can work with either arrangement. Net metering lets a battery shift daytime surplus into evening use without losing the credit. Export-based schemes reward the battery differently, because the stored energy may be sold rather than consumed. Neither is universally better, so run the numbers with your planned battery size and your household’s usage pattern.
Winner for Billing Clarity: Net Metering
Credits appear as adjustments on your regular statement, which makes it easier to see how production is offsetting consumption month by month. Owners often report that this transparency helps them spot a faulty inverter or shading problem sooner than they would under a more complicated arrangement.
Which Should You Choose?
- Choose net metering if your goal is to cover most of your own annual electricity use with rooftop solar.
- Choose net metering if you want a straightforward bill with no separate contract to manage.
- Choose net metering if you plan to add a battery to shift daytime power into evening hours.
- Consider full export compensation if you are building a system much larger than your home needs and want to earn from surplus output.
- Consider full export compensation if you have a commercial or agricultural property with little daytime use.
- Get a site assessment first regardless of the option, because roof orientation, shading and your service capacity determine how much you can actually produce.
Equipment to Consider for a Net Metering Setup
A net metering system needs a grid-tied inverter, a bidirectional meter provided by the utility, and a monitoring tool so you can see production in real time. The products below are common examples of each type. Confirm compatibility with your installer and your local distributor before buying.
Enphase IQ8 Microinverters are a microinverter type often used on residential roofs, where each panel runs independently. View on Amazon
SolarEdge HD-Wave Single Phase Inverter is a string inverter with optimizers, a common choice for unshaded roofs with a single orientation. View on Amazon
For monitoring, a Sense Home Energy Monitor is a whole-home device that tracks production and consumption. View on Amazon
Because these components interact with your utility connection, have a licensed electrician or qualified solar installer handle the interconnection work. Mistakes in grid connection can create safety hazards and delay approval.

FAQ
Do I need a battery to use net metering in Ontario?
No. Net metering works with a standard grid-tied system. A battery is optional and mainly useful if you want to use stored solar power during outages or shift consumption to evening hours.
What happens to credits at the end of the year?
Rules for year-end balances depend on the utility and the program in place. Some arrangements reconcile remaining credits, while others pay out or carry them forward. Ask your distributor for the current policy in writing.
Will my electricity bill drop to zero?
Not usually. Most homes still pay fixed monthly charges, and some usage periods may not be fully offset. Net metering reduces the energy portion of your bill, but it does not eliminate every charge.
Can I use net metering if my roof gets partial shade?
Yes, though output will be lower. Microinverters or optimizers can limit the effect of shade on individual panels. A site assessment will show how much production to expect.
Who should I contact to apply?
Start with your local distribution company and a licensed installer. Your installer typically handles the connection application, and the distributor approves the interconnection and installs or confirms the bidirectional meter. Consult a licensed professional before doing any grid work yourself.
Conclusion
For most Ontario homeowners, net metering is the practical choice. It is simple to understand, rewards using your own solar power, and works with or without a battery. If you plan to build a system far larger than your home needs, or you are running a property with little daytime demand, an export-focused arrangement may suit you better. Get a site assessment, confirm current program rules with your distributor, and have a licensed professional review the design before you commit.
