Solar panels in Waterloo, Ontario
Identical numbers to Kitchener and Cambridge — and a utility only one of them shares.
Waterloo is modelled at 1,155 kWh per kW a year with a payback of 9 to 12 years on a 9 kW system saving about $2,050 — figures it shares exactly with Kitchener and Cambridge. What differs across the tri–cities is not the sunshine but the utility: Waterloo and Kitchener are served by Enova Power, Cambridge by GrandBridge Energy.

Waterloo energy & net metering
What Enova Power 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). Waterloo electricity is distributed by Enova Power. 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.
Enova Power Time-of-Use rates in Waterloo
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.
Enova Power 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 Waterloo buys.
How your system works behind the meter
Most of a Waterloo 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 Enova Power for net-metering credit.

Solar Panels in Waterloo, Ontario
Waterloo produces 1,155 kWh per kW annually – part of the Tri-Cities with Kitchener and Cambridge. Enova Power distributes electricity under Ontario’s Time-of-Use pricing.
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.
The Tri-Cities Share a Number. They Do Not Share a Utility.
Waterloo, Kitchener and Cambridge carry identical figures on this site: 1,155 kWh per kW a year, a 9 kW typical system, about $2,050 in annual saving and a payback of 9 to 12 years. That is not laziness in the data — three adjacent cities on the same stretch of southwestern Ontario genuinely do have the same solar resource, and the modelling reflects it.
Across Ontario that figure sits mid-table: fourteenth or so of the 35 cities on this site, level with Milton and Markham, behind the southwestern group led by Chatham-Kent at 1,210 and ahead of Barrie at 1,130 and the northern cities at 1,050 or below.
Where the tri-cities do differ is in who distributes their electricity. Waterloo and Kitchener are served by Enova Power. Cambridge is served by GrandBridge Energy. Two neighbouring cities, two different local distribution companies, and a municipal boundary that decides which set of forms your installer files.
It is worth being clear that this changes very little about what a system is worth. Time-of-Use pricing is set provincially — 9.8 cents off-peak, 15.7 mid-peak, 20.3 on-peak. The 12 kW threshold for the simplified micro-embedded generation route is an Ontario Energy Board rule. The Home Renovation Savings Program, worth up to $10,000 for solar panels and battery storage together, is provincial, as is the 23.5% Ontario Electricity Rebate.
What the utility affects is administrative: who reviews your connection, who installs the meter, and how quickly. Real for your timeline, irrelevant to your return.
A 9 kW System Keeps You Inside Ontario's Simpler Connection Route
This page assumes a 9 kW system as typical for Waterloo, which matters for a reason that has nothing to do with production.
Ontario draws a line at 12 kW. At or under it, a residential project is micro-embedded generation and follows the shorter connection process. Above it, the standard embedded generation process applies, with more engineering review and a longer timeline. The Ontario Energy Board raised that ceiling from 10 kW on 1 May 2026, and it applies through Enova Power here exactly as it does through every distributor in the province — a provincial rule, not a local policy.
A 9 kW design sits comfortably inside that, with room to grow before the threshold becomes a question. For most Waterloo households that is the right place to be: lighter paperwork, shorter wait.
The change on 1 May 2026 is worth understanding if you are reading older advice. Under the previous 10 kW ceiling, an 11 kW design either went through the longer process or was deliberately derated — limited in output — so it would fit underneath. The OEB said explicitly that raising the ceiling removes the need to derate. Designs that were awkward in Waterloo last year are ordinary this year.
Where it becomes a live decision is a larger home with electric heat, a heat pump or two cars on chargers, where the consumption genuinely justifies 13 or 14 kW. That is allowed and often correct. The thing to avoid is drifting across the line unintentionally and discovering the timeline has moved. Ask your installer early whether the design lands over or under.

Waterloo solar questions
Can I get solar in Waterloo?
Yes. 1,155 kWh/kW production – same as Kitchener and Cambridge.
HRSP ($10K for solar + battery) or net metering available.
Payback: 9-12 years.
What solar rebates are available in Waterloo?
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 Waterloo?
Enova Power distributes electricity in Waterloo.
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 Waterloo?
Enova Power 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.
Why do Waterloo, Kitchener and Cambridge show the same numbers?
Because they genuinely have the same solar resource.
All three are modelled at 1,155 kWh per kW a year with a 9 kW typical system, about $2,050 in annual saving and a 9 to 12 year payback.
Three adjacent cities on the same stretch of southwestern Ontario should look alike, and they do.
What differs is the utility: Waterloo and Kitchener are served by Enova Power, Cambridge by GrandBridge Energy.
That affects whose forms your installer files and how quickly the meter arrives, not what the system is worth — Time-of-Use rates, the 12 kW connection threshold and the $10,000 provincial rebate are identical across all three.
How does Waterloo compare with the rest of Ontario for solar?
Mid-table, and comfortably viable.
At 1,155 kWh per kW a year Waterloo sits around fourteenth of the 35 Ontario cities on this site — level with Kitchener, Cambridge, Milton and Markham, behind the southwestern group where Chatham-Kent leads at 1,210, and ahead of Barrie at 1,130 and the northern cities at 1,050 or below.
The whole province spans about 17 per cent from top to bottom, so mid-table here is a long way from marginal.
Your roof orientation and shading will move your production more than the gap between Waterloo and the provincial leaders.
