TORONTO, ON - As Ontario's solar incentive landscape continues to evolve, Terawatt Solar is helping homeowners across the Greater Toronto Area evaluate the financial benefits of two distinct solar pathways available in 2026: traditional net metering and solar systems paired with battery storage.
The Ontario Home Renovation Savings (HRS) Program currently offers up to $10,000 in stackable rebates, including up to $5,000 for solar photovoltaic (PV) systems and up to $5,000 for battery storage. At the same time, municipal Property Assessed Clean Energy (PACE) financing programs available in municipalities such as Toronto, Durham Region, and Guelph continue to provide homeowners with access to low-interest or 0% financing options for qualifying energy upgrades.
According to Ontario solar panel provider Terawatt Solar, many homeowners are surprised to learn that the most financially attractive solar solution may vary significantly depending on electricity consumption patterns, roof orientation, utility rates, and whether battery storage is included.
"Homeowners are no longer simply asking whether solar makes sense," said a spokesperson for Terawatt Solar. "They're asking which solar strategy delivers the strongest return over the next 20 to 25 years. The answer often depends on whether they prioritize net metering credits or leverage battery storage alongside available provincial rebates."
Under Ontario's net metering framework, homeowners can export excess solar energy to the grid and receive one-for-one energy credits from their local utility provider. This approach typically offers a lower upfront investment because battery storage is not required.
Alternatively, homeowners can install solar panels with battery storage and pursue available HRS rebates. Battery systems can store excess solar production and may also take advantage of Ontario's Ultra-Low Overnight (ULO) electricity rates. Through a strategy commonly referred to as energy arbitrage, homeowners can charge batteries during overnight periods when rates are approximately 3.9 cents per kilowatt-hour and utilize that stored energy during peak pricing periods when rates can exceed 39 cents per kilowatt-hour.
Terawatt Solar's internal financial modeling illustrates how the two approaches can produce different outcomes over the lifespan of a system.
These estimates assume typical Ontario electricity inflation rates, average solar production conditions, and homeowner participation in time-of-use optimization strategies. Actual results vary based on location, shading, system design, and electricity consumption patterns.
Beyond energy savings, battery-equipped homes may also benefit from backup power capabilities during outages and potential increases in property value. Industry observations suggest that homes equipped with solar and battery storage continue to attract increased buyer interest as energy costs rise throughout Ontario.
"We encourage homeowners to compare both options before making a decision," added the spokesperson. "A customized analysis can often reveal opportunities that aren't obvious when looking solely at system pricing."
To support homeowners evaluating their options, Terawatt Solar provides comprehensive consultations that include system design recommendations, utility interconnection guidance, rebate application support, and installation services utilizing high-efficiency N-Type TOPCon solar technology designed for Canadian weather conditions.
