Imagine slashing your hydro bills by hundreds of dollars each year while contributing to a cleaner planet, all while making a smart investment in your Ontario home. With electricity rates rising and new incentives in place for 2026, solar power has never been more appealing for Canadian homeowners. But there’s a crucial choice: the Home Renovation Savings (HRS) rebate or traditional net metering.
At Net Zero Homes, we’ve helped hundreds of Ontario families navigate this decision through detailed energy modeling based on their actual usage. This isn’t just about upfront costs, it’s about maximizing savings over the next 25+ years. Whether you’re in Toronto, Ottawa, Hamilton, or a rural area served by Hydro One, understanding these paths helps you choose what fits your lifestyle best.
Understanding the Two Paths for Solar in Ontario
Ontario homeowners generally can’t combine both options fully due to program rules. You typically choose one financial strategy for your solar setup.
Net Metering (Path A): Your solar panels connect to the grid. When they produce more electricity than your home uses (like sunny afternoons), excess power flows back, earning you credits at your full retail rate. These credits offset future bills. It’s ideal for exporting excess power.
HRS Rebate with Load Displacement (Path B): You qualify for upfront rebates—up to $5,000 for solar ($1,000 per kW, max 5 kW) and another $5,000 for battery storage ($300 per kWh)—but your system must be sized primarily for on-site use with minimal or no exports. Net metering is not allowed with the solar rebate under HRS
Both approaches deliver strong returns, but the best one depends on your roof, daily routines, and rate plan.
Under Ontario Regulation 541/05, net metering gives you 1:1 credits for exported electricity at the energy portion of your retail rate (delivery, regulatory charges, and taxes are separate). Credits roll over month-to-month but expire after 12 consecutive months of carryover.
Current approximate retail rates (energy charge only, varying by utility and plan):
- Time-of-Use (TOU): 9.8¢ off-peak, up to ~20¢ on-peak.
- Tiered: Around 10–12.5¢/kWh.
- Ultra-Low Overnight (ULO): As low as 3.9¢ overnight to 39.1¢ on-peak weekdays.
Real homeowner story: Sarah, a teacher in Mississauga with a south-facing roof, installed an 8 kW system without a battery. During summer, her daytime exports generated enough credits to nearly eliminate winter bills. Her payback came in under 8 years thanks to consistent credits.
Net metering shines for homes with good daytime production and lower evening use, or those staying on standard TOU/Tiered plans without heavy battery needs.
The HRS Rebate Path: Upfront Savings and Load Displacement
The Home Renovation Savings program (delivered by Save on Energy / IESO and Enbridge Gas) offers compelling incentives for energy upgrades. For solar + battery, you can get up to $10,000 combined, but the system must prioritize self-consumption.
Key rules:
- Pre-approval required before purchase or installation.
- Must use a registered contractor (Net Zero Homes is qualified).
- Battery must pair with new solar (not standalone for the full incentive).
- Eligible for detached, semi-detached, townhomes, etc. (owner-occupied).
Pairing with the Ultra-Low Overnight (ULO) rate plan unlocks extra value. Charge your battery with cheap overnight power (3.9¢/kWh) or daytime solar, then use it during high-cost 4–9 PM peaks (39.1¢/kWh). This arbitrage can add significant annual savings for families cooking, charging EVs, or running laundry in the evening.
Scenario: The Patel family in Ottawa has high evening usage with two teens and an EV. Their HRS-funded 6 kW solar + battery setup, on ULO, shifted loads perfectly. They saved on bills immediately and gained outage protection.
Side-by-Side Comparison
| Factor | Net Metering | HRS Rebate + Load Displacement |
|---|---|---|
| Upfront Incentive | None for solar (battery may qualify separately) | Up to $10,000 ($5K solar + $5K battery) |
| Savings Mechanism | 1:1 export credits (~10–20¢/kWh) | Self-consumption + ULO arbitrage |
| System Sizing | Can be larger for exports | Right-sized to home use + storage |
| Battery Value | Optional (backup/reliability) | Central (peak shaving + backup) |
| Best For | Daytime exporters, no/limited battery | Evening-heavy homes on ULO |
| Payback Typical | 7–10 years | 6–9 years with full stack |
| Outage Protection | With added battery | Strong with battery design |

Benefits and Drawbacks
Net Metering Benefits: Simple, flexible sizing, great for maximizing summer production credits. Drawbacks: No big upfront rebate, credits can expire if not used.
HRS Benefits: Immediate cash back reduces net cost, pairs beautifully with batteries and ULO for arbitrage, supports broader home upgrades like heat pumps or insulation. Drawbacks: Stricter sizing (less export), pre-approval process, can’t net meter the solar portion.
Environmental Wins: Both reduce reliance on fossil fuels. A typical Ontario solar system offsets 5–10 tonnes of CO2 annually—equivalent to planting dozens of trees.
Actionable Takeaways for Ontario Homeowners
- Review your bills: Download 12 months of hourly data from your utility portal.
- Assess your roof and usage: South-facing? Empty daytime? Evening peaks?
- Consider a full upgrade: Combine solar with air sealing, high-performance windows, insulation, or heat pumps for maximum efficiency and rebates.
- Get modeled quotes: Avoid one-size-fits-all—demand data-driven projections.
- Plan for the future: Factor in EV chargers, home batteries, and rising rates.
Cost Considerations and ROI in 2026
A typical 6–8 kW solar system might cost $20,000–$35,000 before incentives (varies by location and equipment). HRS can cut that by up to $10,000. Add federal or local programs where available, plus potential low-interest financing.
ROI examples (modeled averages):
- High-export net metering: 7–9 years payback, strong lifetime savings.
- HRS + battery + ULO: Often 6–8 years, with added resilience.
Maintenance is low—panels last 25–30+ years with occasional cleaning. Batteries need monitoring but modern systems are reliable. Always verify current pricing with Net Zero Homes.
Common Mistakes to Avoid
- Skipping pre-approval for HRS (rebates denied).
- Oversizing for net metering without checking credit expiration.
- Ignoring rate plan switch to ULO when it fits your lifestyle.
- Choosing an unregistered contractor.
- Not considering whole-home efficiency (insulation, windows, heat pumps) alongside solar.
Frequently Asked Questions
Can I do both HRS rebate and net metering? Generally no for the solar portion under HRS rules. You must choose the path that best matches your needs.
Is the HRS program still available in 2026? Yes, with funding first-come, first-served. Act soon and get pre-approved.
What if I have high daytime usage? HRS load displacement often wins with self-consumption and battery.
How does ULO affect savings? The large spread (3.9¢ to 39.1¢) makes battery arbitrage powerful for evening users.
Do I need a home energy audit? Helpful for full optimization, though single-measure HRS paths may not require one. Net Zero Homes offers comprehensive audits.
What about other provinces? Ontario’s setup is unique; Net Zero Homes can advise on national options like Canada Greener Homes resources.
How long do net metering credits last? Up to 12 months, then they reset.
Final Thoughts
The “right” choice between HRS rebate and net metering in Ontario 2026 comes down to your unique home—usage patterns, roof orientation, and goals for energy independence. Neither is universally superior, but getting it right can mean thousands more in your pocket over time.
