Solar panels in Sault Ste. Marie, Ontario
The lowest sun in Ontario, and the fourth-highest saving in the province.
Sault Ste. Marie is modelled at 1,030 kWh per kW a year — the lowest figure of any Ontario city on this site. And yet the average saving quoted here, about $2,380 a year, is the fourth–highest of any Ontario city, behind only Thunder Bay, Huntsville and Toronto. Payback runs 10 to 14 years on a 10 kW system. Both facts are true at once, and understanding why is the most useful thing on this page.

Sault Ste. Marie energy & net metering
What PUC Distribution Inc. 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). Sault Ste. Marie electricity is distributed by PUC Distribution Inc. 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.
PUC Distribution Inc. Time-of-Use rates in Sault Ste. Marie
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.
PUC Distribution Inc. 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 Sault Ste. Marie buys.
How your system works behind the meter
Most of a Sault Ste. Marie 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 9.8–20.3¢/kWh. Only the surplus flows past the meter to PUC Distribution Inc. for net-metering credit.

Solar Panels in Sault Ste. Marie, Ontario - Northern Ontario
Sault Ste. Marie produces 1,030 kWh per kW annually – the lowest of Ontario cities tracked, but solar remains viable. PUC Distribution Inc. distributes electricity. Higher electricity costs in northern areas can offset lower production. HRSP ($10K) helps the economics.
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.
Ontario's Weakest Sun, and One of Its Largest Savings
Sault Ste. Marie is modelled at 1,030 kWh per kW a year. That is the lowest figure of the 35 Ontario cities on this site — below Thunder Bay, Sudbury and Huntsville at 1,050, and about 15 per cent behind Chatham-Kent at 1,210.
So it is worth explaining why the average saving quoted here, $2,380 a year, is higher than in Mississauga, Oakville, Hamilton or Guelph, all of which get better sun.
The answer is that a saving is production multiplied by consumption displaced, and northern households consume more. This page assumes a 10 kW system as typical, the same as the GTA despite weaker sun, because the bill being offset is larger — longer heating seasons, more lighting through dark winters, and more electric load generally. A 10 kW system at 1,030 produces about 10,300 kWh a year, which is a great deal of electricity to take off a bill.
What weaker sun does affect is the payback, which runs 10 to 14 years here against 7 to 10 in the southwest. The system is not cheaper to buy just because the sun is weaker, so a longer wait is the price of the larger annual saving.
The practical reading: if you are staying in the house, Sault Ste. Marie is a better place to own solar than its position at the bottom of the Ontario sunshine table suggests. If you are likely to move within a few years, the southwest of the province recovers its cost considerably faster.
Your Distributor Is PUC Distribution, and the City Owns It
Electricity in Sault Ste. Marie is distributed by PUC Distribution Inc., the licensed local distribution company. It is worth naming precisely, because the group has more than one entity and they do different things.
PUC Inc. is a holding company registered under the Ontario Business Corporations Act and wholly owned by the Corporation of the City of Sault Ste. Marie. PUC Distribution Inc. is the LDC — it distributes electricity to homes and businesses within the City of Sault Ste. Marie, the Batchewana First Nation at Rankin Reserve, Prince Township and parts of Dennis Township. PUC Services Inc. is a utility services company, also city-owned, which supplies drinking water and electricity and operates wastewater treatment.
For a solar customer that distinction matters mainly when you are filling in forms or chasing a connection: the net metering agreement is with the distributor.
What municipal ownership does not change is the rules. Time-of-Use pricing is set provincially by the Ontario Energy Board. The 12 kW threshold that decides whether your project takes the simplified micro-embedded generation route was raised from 10 kW by the OEB on 1 May 2026 and applies here as everywhere else. Ontario’s Home Renovation Savings Program, worth up to $10,000 for solar panels and battery storage together, is provincial. So is the 23.5% Ontario Electricity Rebate.
What a small municipally-owned utility does affect is the practical side — who answers the phone about your connection, and how quickly the offer to connect and the meter arrive.

Sault Ste. Marie solar questions
Is solar worth it in Sault Ste. Marie?
Production is lower (1,030 kWh/kW) but still viable.
HRSP ($10K for solar + battery) helps the economics.
Payback: 10-14 years.
Higher electricity costs in northern Ontario offset lower production.
What solar rebates are available in Sault Ste. Marie?
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).

The federal Greener Homes programs are now closed.
Who provides electricity in Sault Ste. Marie?
PUC Distribution Inc. 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 Sault Ste. Marie?
PUC Distribution Inc. 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, systems up to 12 kW qualify for Ontario’s simplified micro-embedded connection process (up from 10 kW); larger systems can still net-meter through the standard connection process.
Note: Solar under HRSP cannot use net metering.
If Sault Ste. Marie has Ontario's weakest sun, why is the saving so high?
Because the saving depends on the bill as much as the sunshine.
At 1,030 kWh per kW a year this is the lowest modelled figure of any Ontario city on this site — but the average saving quoted here, about $2,380, is the fourth-highest of any Ontario city, behind only Thunder Bay, Huntsville and Toronto.
Northern households consume more electricity through longer, darker, colder winters, so the systems built here are sized to displace more: this page assumes 10 kW, the same as the GTA, despite the weaker resource.
The trade-off shows up in the payback rather than the saving — 10 to 14 years here against 7 to 10 in southwestern Ontario.
Who actually connects a solar system in Sault Ste. Marie?
PUC Distribution Inc., the licensed local distribution company.
The group is city-owned: PUC Inc. is a holding company wholly owned by the Corporation of the City of Sault Ste.
Marie, PUC Distribution is the electricity distributor, and PUC Services Inc. is a separate utility services company supplying water and electricity and running wastewater treatment.
Your net metering agreement is with the distributor.
PUC Distribution serves the City of Sault Ste.
Marie, the Batchewana First Nation at Rankin Reserve, Prince Township and parts of Dennis Township — so addresses outside the city proper may still be on the same system.
