Net Metering vs Net Billing: What's Best in 2026?
Canadian solar buyers in 2026 keep running into two similar-sounding terms that can change solar payback by years: net metering and net billing. This guide gives the straight answer, then localizes it province by province.
Net metering and net billing compensate exports differently, which changes payback and system sizing.
Net metering credits exported electricity so it can offset future consumption (often close to retail rate).
Net billing pays a distinct export price for power sent to the grid (often lower than retail).
The best model depends on export value, credit expiry, and self-consumption.
Executive summary
For Canadian homeowners and small businesses in 2026, “net metering vs net billing” is less a single national choice and more a provincial reality: the “best” model depends on (a) whether exports are credited at (or near) the retail rate, (b) how long credits roll over before expiring or being cashed out, and (c) how well your site can self-consume solar (daytime loads, heat pumps, EV charging, batteries).
The economic rule of thumb remains stable: when exports are credited like a 1:1 retail offset (classic net metering), projects can achieve stronger payback without needing batteries. When exports are paid at a distinct “sell” rate (net billing), maximizing self-consumption becomes the main lever.
- •Explicit net billing with an “excess energy price” (listed as $0.04390/kWh until March 31, 2026) highlights why export-heavy systems can underperform.
- •Active rate proceedings in another province propose a fixed 10¢/kWh export price and a 20-year legacy period for existing customers, making 2026 a “watch-the-decision” year.
What changed for solar compensation this year
The most SEO-relevant “what’s new” angle for 2026 Canadian readers is that some jurisdictions are moving from traditional kWh-credit net metering toward “net billing-like” designs that separate the value of imported electricity from the value of exports. Utility workshop materials frame this shift in terms of cost recovery and price signals, noting that retail netting may not recover certain fixed customer costs.
This is consistent with international regulatory trends: net metering was widely adopted as an early-market tariff, but successor designs are emerging as solar adoption grows. For Canada-specific context, the IEA PVPS national survey provides a credible snapshot of provincial support measures and cost context.
Definitions and mechanics
Net metering
Net metering credits exported electricity so it offsets consumption at (or close to) your per‑kWh rate. The credits usually roll forward within a defined period and are applied against eligible usage charges.
Net billing
Net billing separates buying from selling: you avoid buying kWh you self-consume, but any exports are paid at a distinct export price and appear as a monetary credit.
The practical difference that drives ROI
Solar ROI is driven by two values: the value of self-consumption (each kWh you use on-site avoids your retail charge) and the value of export (each kWh you send to the grid is paid at the export compensation). Under net billing, the export price is often lower than retail because retail rates recover services like transmission and distribution.
| Attribute | Net metering (typical) | Net billing (typical) | Why it matters for 2026 |
|---|---|---|---|
| Compensation method | kWh credits offset future consumption | Monetary credit at a stated export price | Export value can diverge sharply from retail |
| Export “rate” structure | Often tied to eligible consumption rate | Stated export price that can change annually | Net billing increases reliance on self-consumption |
| Credit rollover & expiry | Often time-limited (12 months, annual reset, multi‑year) | Monetary credit rules vary by utility | Expiry shapes optimal sizing |
| Charges that can be offset | Often only usage-related charges | Depends on utility rules | Fixed charges reduce effective value |
| Best-candidate customers | Annual production close to annual load | High self-consumption or storage | Export value gap is the central driver |
How net metering works in Canada
Under net metering, your home or business uses solar power first. When you generate more than you need, the excess flows to the grid and you receive credits used to offset future consumption.
One important nuance for Canadian readers: net metering credits often do not offset every line item on a bill. Credits can apply to usage-related charges (kWh), but fixed customer fees typically remain.
Credit expiry and true-up rules
- •Some provinces limit carry-forward to 12 months.
- •Some utilities reset credits on a specific date each year (example: March 31).
- •Other programs reset on a multi‑year schedule (example: 24 months).
Solar X rule of thumb: If credits can expire, do not oversize “just because roof space is available.” Oversizing can turn valuable kWh into expiring credits.
How net billing works in Canada
Net billing changes what happens when you export. You still benefit from using your own solar energy in real time, but exported kWh are paid at an export price and posted as a monetary credit.
Example: Excess energy price
A provincial utility lists an “excess energy price” of $0.04390/kWh until March 31, 2026 and explains why it differs from retail: retail rates recover service costs like transmission and distribution, while export prices reflect market value and are updated yearly.
Why self-consumption matters more under net billing
If exported kWh are paid at a lower export price, ROI becomes sensitive to when you use electricity. Utilities often advise that properly sized systems that self-consume most energy provide better payback than exporting excess.
Daytime loads
Work-from-home, daytime HVAC
EV & heat pump
Scheduled charging during solar hours
Battery storage
Shift solar into evening usage
Which is best in 2026?
If you have access to classic net metering with generous rollover and retail-like crediting, net metering often produces the strongest payback for typical homes without requiring a battery. If your jurisdiction uses net billing or a hybrid design, net billing can still be excellent when you maximize self-consumption and avoid chronic surplus exports.
In 2026, the practical “best” answer is:
- Check your export value and expiry rule. Treat exports as lower value when the export price is distinct.
- Model your load shape. A system matching daytime use often beats a larger system with low export prices.
- Watch policy stability. Active proceedings can change export valuation in 2026.
A quick ROI example
Assume a system produces 9,000 kWh/year:
- •Net billing: With 45% self-consumption and 55% export, payback depends heavily on export price (example: $0.04390/kWh until March 31, 2026).
- •Net metering: Exports can be worth more, but savings are still limited by non-offsettable fixed charges and credit expiry rules.
Solar X best practice: We size your system against (a) annual consumption, (b) seasonal mismatch, and (c) your tariff’s rollover/true-up rule—then test whether a battery improves outcomes.
Net Metering vs Net Billing by Province (2026)
Canada’s residential solar compensation is a patchwork. Below is a snapshot of how each province approaches post-generation compensation as of early 2026.
| Province | Netting model | Export valuation signal | Credit rollover / expiry | Sizing watch-outs |
|---|---|---|---|---|
| British Columbia | Hybrid moving toward net billing-like | Market price payout; proposed fixed 10¢/kWh (if approved) | Annual payout; proposed 20-year legacy period | Monitor regulator decision timeline |
| Alberta | Retail-credit for small micro-generators | Retail rate agreed with your retailer | Credits applied monthly | Retailer contract design matters |
| Manitoba | Net billing | Excess energy price (example: $0.04390/kWh) | Monetary credits; export price updated yearly | Strong incentive to self-consume |
| Ontario | Net metering (kWh credits) | Credits offset usage-related charges | 12‑month carry-forward | Avoid oversizing; credits can expire |
| Quebec | Net metering (kWh credit bank) | kWh credits; no cash exchange | Reset every 24 months | Credit expiry is a sizing constraint |
| Saskatchewan | Net metering | Pre‑determined export rate | Credit carried forward for account life | Confirm current export rate at time of install |
| Nova Scotia | Net metering (commercial tiers) | Retail offset with program caps | Program rules by utility | Demand charges and class matter |
| New Brunswick | Net metering | Program not intended for selling power | Credits reset March 31 annually | Size to annual load |
| Prince Edward Island | Net metering (kWh credits, no cash) | Credits have no cash value | Carry forward until Dec 31 next year | Sizing and load shaping matter |
| Newfoundland & Labrador | Hybrid net metering with true-up | Annual settlement at referenced rates | Annual review period | Design for self-use as primary value |
Note: Policy changes happen between updates. Always verify with your utility or Solar X before sizing.
Quick checklist: net metering or net billing?
Net metering tends to fit when:
- •Exports are credited near retail for eligible charges.
- •Rollover windows are long enough for seasonal balancing.
- •System size tracks annual load with minimal surplus.
Net billing tends to fit when:
- •Exports are compensated at a distinct export price.
- •You can self-consume more (EV/heat pump scheduling).
- •You want a design robust to export price changes.
FAQs
Is net billing always worse than net metering?
Not always. Net billing can be excellent for customers who self-consume a high share of production. Where export prices are lower than retail, self-consumption is the driver.
Why is the export price lower than the retail rate under net billing?
Retail rates recover service costs such as transmission and distribution, while export prices reflect market value and are updated yearly.
Do net metering credits cover my whole bill?
Often, no. Credits typically offset usage-related charges, while fixed customer fees remain.
Can net metering credits expire?
Yes. Examples include 12‑month carry-forward limits, annual reset dates, and multi‑year resets. Always verify your utility’s rules before sizing.
What if my province is changing net metering rules in 2026?
Follow the regulator docket and the utility’s rate update page. Some provinces expect decisions in early 2026 with potential effective dates in April 2026.
What system size is “best” under net billing?
Generally, the best size maximizes self-use and avoids chronic exports at low export prices. Utilities often publish payback formulas that weight self-used energy at retail and exports at the export price.
Do batteries help more under net billing or net metering?
Batteries tend to help more when export value is lower than self-consumption value, since storage shifts solar into higher‑value usage periods.
How do I estimate solar production for my location in Canada?
Use national solar resource datasets and PV potential tools, then adjust for shading and roof orientation.
What about small businesses with demand charges?
Rate classes can affect ROI. Verify whether demand charges remain and how credits apply in your tariff class.
What should I bring to a Solar X consultation?
Bring 12 months of bills, your rate plan details, and any planned electrification (EV/heat pump). That’s enough to model self-consumption vs export and match the system to your program’s rollover rule.
