Solar panels in Sudbury, Ontario
The least sun of anywhere we work in Ontario bar one — and still a ten-year payback.
Sudbury is modelled at 1,050 kWh per kW a year. On our Ontario list only Sault Ste. Marie is lower, and yet the average Sudbury customer saves more per year than one in London, Oshawa, Niagara Falls or St. Catharines. That is not a contradiction, and the reason is worth understanding before you read a quote.

Sudbury energy & net metering
What Greater Sudbury Hydro charges here, and how surplus solar is credited in Ontario.
Ontario’s Time–of–Use electricity rates range from 9.8¢/kWh (off–peak) to 20.3¢/kWh (on–peak), with mid–peak at 15.7¢/kWh (OEB RPP, Nov 2025–Oct 2026). Sudbury electricity is distributed by Greater Sudbury Hydro. Solar panels generate most during daytime on–peak hours, earning you credits at the highest rate. The Ontario Electricity Rebate provides a 23.5% discount on your bill.
Greater Sudbury Hydro Time-of-Use rates in Sudbury
What a kilowatt-hour costs at each tier, and the hours each one applies — OEB Regulated Price Plan, Nov 2025 – Oct 2026. Rates are set province-wide by the Ontario Energy Board, so they are the same whichever utility bills you; only delivery charges differ.
Greater Sudbury Hydro peak hours, by season
The tiers hold all year; the hours switch twice a year. Weekends and statutory holidays bill at the off-peak rate all day, in both seasons.
On-peak power costs 2.1× what the same kilowatt-hour costs off-peak. At the Ontario Energy Board's benchmark of 700 kWh a month, that is the difference between $68.60 and $142.10 on the electricity line alone — delivery and regulatory charges are billed separately, and the Ontario Electricity Rebate then takes 23.5% off the total.
This is why solar pays better here than a flat rate would suggest. A rooftop array produces most between 11 a.m. and 5 p.m. — precisely the summer on-peak window — so the power it offsets is the most expensive power Sudbury buys.
How your system works behind the meter
Most of a Sudbury system's value comes from power used behind the meter — electricity your panels make and your home uses on the spot, offsetting energy you'd otherwise buy at 9.8¢/kWh. Only the surplus flows past the meter to Greater Sudbury Hydro for net-metering credit.

Solar Panels in Sudbury, Ontario - Northern Ontario
Sudbury has lower but still viable solar production at 1,050 kWh per kW annually. Greater Sudbury Hydro distributes electricity. Northern Ontario’s clear skies and long summer days support solar performance. Higher electricity costs in northern areas can partially offset lower production.
Ontario’s net metering program credits excess solar at the full retail rate. HRSP ($10K for solar + battery) or net metering available – but not both.
Ontario HRSP - Up to $10,000 for Solar + Battery
Ontario’s Home Renovation Savings Program (HRSP), launched January 2025, offers:
- Up to $5,000 for solar panels ($1,000/kW)
- Battery storage at $300/kWh up to $5,000
- HRSP maximums are per category rather than one shared pot: up to $10,000 for solar and storage, up to $12,000 for heat pumps, up to $7,700 for insulation
Important – HRSP vs. Net Metering: Solar installed under HRSP must be sized for on-site load displacement only – net metering is not permitted under HRSP. If you prefer net metering (earning 1:1 credits for excess solar), you would not apply through HRSP. Your Xolar advisor can help determine which option provides the best return.
Note: The Canada Greener Homes Grant and Loan programs are now closed.
Sudbury Gets Less Sun Than Almost Anywhere We Serve. It Still Saves the Most.
Sudbury is modelled at 1,050 kWh per kW a year. That places it 33rd of the 35 Ontario cities on this site — only Sault Ste. Marie, at 1,030, is lower, and Thunder Bay and Huntsville match it exactly. Set against Chatham-Kent at 1,210, a panel in Sudbury gives up around 13 per cent of its annual output.
So it is worth explaining why the average Sudbury customer saves $2,350 a year — more than London at $2,100, more than Oshawa at $2,150, more than Niagara Falls at $2,100 and more than St. Catharines at $2,080. Every one of those cities gets better sun than Sudbury does.
The answer is that a solar system is sized to a house, not to a latitude. The typical system size quoted for Sudbury is 10 kW, against 9 kW for London and 9 kW for Oshawa. A northern house is heated harder and runs bigger electrical loads through a longer winter, so the bill being offset is larger and the system built to offset it is larger too. Ten kilowatts at 1,050 kWh/kW produces about 10,500 kWh a year; nine kilowatts at Oshawa’s 1,140 produces about 10,260.
What this does not do is shorten the payback. Sudbury runs 10 to 13 years against London’s 8 to 11, because a bigger system costs more to buy in the first place. Weaker sun on a larger roof buys a larger annual saving for a larger up-front cost — a better absolute return, not a faster one.
If you are holding a Sudbury quote up against a figure a friend in southern Ontario mentioned, that is the distinction worth keeping straight. The right question is not whether Sudbury gets enough sun. It plainly does. The question is how many years you intend to stay in the house.
Greater Sudbury's Own Retrofit Programme Pays No Rebates — and Is Currently Waitlisted
The City of Greater Sudbury runs CHIRP, the Community Home Improvement and Resilience Program. It is worth knowing what it is, because the name suggests a rebate and it is not one. The City puts the position plainly: CHIRP is a guidance and support service, and the City of Greater Sudbury does not perform construction work or provide direct rebates.
What it does provide is free one-on-one support from a Home Improvement Navigator, who helps you understand your energy use, weigh up retrofit options, and identify which grants and rebates you can actually claim. For a homeowner trying to work out how solar sits alongside insulation and a heat pump, that is genuinely useful. It is advice, not money.
As of this writing the programme is not taking new participants. The City says that because of high interest its team is working one-on-one with existing participants and will not be able to begin with new ones until those requests are complete; applications are being taken onto a waitlist in the meantime.
None of that affects what you can claim. Ontario’s Home Renovation Savings Program covers solar panels and battery storage together, up to $10,000, and is administered provincially rather than by the City — so a CHIRP waitlist does not hold it up. Greater Sudbury Hydro handles your net metering connection separately again. CHIRP is a useful front door when it is open. It is not a gate you have to get through first.

"Xolar installed panels to our home. They were very professional and excellent at getting back to us. I would definitely recommend them to others ."
"Part one- the quote: Dylan was friendly, communicates clearly, promptly, and through convenient methods. His quote and explanations are precise and transparent. A good experiencePart two- installation in update post"
"I had my solar system installed by Xolar and I’m extremely satisfied with both the hardware and the overall setup. The system delivers immediate savings on my Hydro bill and is performing better than I expected, even under winter conditions. The hardware layout is clean, thoughtfully designed, and integrates seamlessly with my existing electrical system.The project timeline was solid: I placed my order in August, the installation took place over the winter, and everything was fully completed by April, including all permits and approvals from the city. The only hiccup in the entire process was a hardware shortage during the ordering phase, which required me to follow up a few times. That delay was frustrating, but ultimately handled well.A special mention goes to Lauren, who has been a great point of contact from start to finish. She is responsive, clear in her communication, and consistently advocated on my behalf to resolve issues and push past any delays. Having someone like Lauren to talk to made a big difference and kept my confidence in the project high.Overall, I would definitely recommend Xolar to anyone considering a solar installation. Once the hardware arrived, everything moved smoothly, the system was set up correctly the first time, and the performance and savings so far have exceeded my expectations."
"Spoke with a representative. Very pleasant and professional.all representatives of the team were helpful, courteous and professional. I highly recommend Xolar"
"Xolar rep is very knowledgeable about solar product and the government rebates that can help make the project happen. Spencer was able to answer all my questions and made the decision to proceed with the application an easy one."
"They provided a very thorough proposal and walked us through it in detail."
Sudbury solar questions
Does solar work in Sudbury?
Yes. 1,050 kWh/kW is lower than southern Ontario but still viable.
Long summer days and clear northern skies help.
HRSP ($10K) or net metering available.
Payback: 10-13 years.
What solar rebates are available in Sudbury?
Ontario’s HRSP provides up to $5,000 for solar + battery storage at $300/kWh up to $5,000 (heat pumps carry a separate $12,000 maximum).
Important: HRSP solar cannot use net metering – customers must choose one or the other.
The federal Greener Homes programs are now closed.
Who provides electricity in Sudbury?
Greater Sudbury Hydro distributes electricity.
Ontario’s Time-of-Use rates: 9.8¢ off-peak, 15.7¢ mid-peak, 20.3¢ on-peak.
The Ontario Electricity Rebate provides a 23.5% discount.
How does net metering work in Sudbury?
Greater Sudbury Hydro offers 1:1 net metering – excess solar earns credits at the full retail rate.
Credits roll over for 12 months.
As of May 1, 2026, the net metering system size threshold was raised to 12 kW for residential customers.
Note: Solar under HRSP cannot use net metering.
If Sudbury has poor sun, why is the average saving higher than in London?
Because the system is bigger.
The typical system size quoted for Sudbury is 10 kW against 9 kW for London, and a northern house running a longer, colder heating season has a larger bill to offset in the first place.
Sudbury’s average saving works out at $2,350 a year against London’s $2,100, even though a London panel produces about 11 per cent more per kW installed.
The trade-off appears in the payback rather than the saving: Sudbury runs 10 to 13 years and London 8 to 11, because the larger system costs more to buy.
Who connects a solar system in Sudbury, and does the City pay anything towards it?
Greater Sudbury Hydro Inc. is the licensed distributor and handles the net metering connection.
It is part of Greater Sudbury Utilities Inc. and distributes to over 48,300 customers across the City of Greater Sudbury and the Municipality of West Nipissing — so if your address is in West Nipissing rather than Sudbury proper, it is still the same utility.
The City itself pays nothing towards solar: CHIRP is explicitly a guidance service that does not provide direct rebates, and it is currently waitlisted.
The money comes from Ontario’s Home Renovation Savings Program, up to $10,000 for solar panels and battery storage together.
