Solar panels in Guelph, Ontario: 3 Xolar installs in Guelph
Smaller systems, smaller savings — the lowest of any Alectra city we serve.
Guelph is modelled at 1,150 kWh per kW a year with a payback of 9 to 12 years, but the figure worth knowing is the saving: about $2,050 a year, the lowest of the nine Alectra–served cities on this site. That is not a statement about Guelph’s sunshine, which is ordinary for southern Ontario. It reflects smaller typical systems — 9 kW here against 10 kW in most of the Alectra group — sized to smaller household consumption.

Aggregated from completed Xolar systems in Guelph — first-hand data, not industry averages.
Guelph energy & net metering
What Alectra Utilities 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). Guelph electricity is distributed by Alectra Utilities. 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.
Alectra Utilities Time-of-Use rates in Guelph
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.
Alectra Utilities 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 Guelph buys.
How your system works behind the meter
Most of a Guelph 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 Alectra Utilities for net-metering credit.

Solar Panels in Guelph, Ontario
Guelph produces 1,150 kWh per kW of installed solar capacity annually. Alectra Utilities distributes electricity. Ontario’s Time-of-Use pricing means solar earns maximum credits during on-peak hours (20.3¢/kWh).
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.
Guelph Has the Smallest Systems and the Smallest Savings of Any Alectra City
Of the nine cities on this site served by Alectra Utilities, Guelph quotes the lowest average annual saving: about $2,050, against $2,350 in Markham, $2,300 in Mississauga, Vaughan and Richmond Hill, and $2,200 in Brampton.
It is not a sunshine problem. Guelph is modelled at 1,150 kWh per kW a year, the same figure as Richmond Hill, Vaughan, Whitby, Pickering, Ajax and St. Catharines, and only about 1.7 per cent behind Mississauga’s GTA-leading 1,170. On production per kilowatt installed, Guelph is unremarkable rather than poor.
The difference is system size. This page assumes 9 kW as typical, where most of the Alectra group assumes 10 kW — a figure shared only with Hamilton and Barrie. A smaller system generates less, saves less and costs less. Guelph’s housing stock includes a large share of smaller and older homes, and a university city has a correspondingly different consumption profile from a commuter suburb of large detached houses.
What that should change about your reading of this page is the direction of the adjustment. If you live in a larger Guelph home with electric heating or a car on a charger, the $2,050 figure understates your case, probably substantially — your system would be sized nearer the 10 kW that neighbouring cities assume. If you are in a compact older house on a modest bill, it may be about right.
The payback band of 9 to 12 years is the same as most of the Alectra group, because a smaller system also costs less to buy. Scale changes both sides of that ratio.
Guelph's City Loan Has a Waitlist, So Financing Matters
Guelph has a long-standing reputation for municipal environmental ambition, and it does run its own home energy programme, Guelph Greener Homes: a zero-interest loan, plus grants for eligible low-income households. The catch is timing. Loan funding is almost all spoken for and a waitlist is open, so check with the City whether your project qualifies before counting on it.
Better Homes Ontario, which catalogues these programmes, lists Kingston, Ottawa, Toronto and Durham Region — though Kingston’s has since stopped accepting applications, which is a reminder that these come and go. Toronto’s Home Energy Loan Program lends up to $125,000. Durham Region lends up to $125,000 at 2% over fifteen years. London, outside that catalogue, runs BetterHomes London at up to $40,000 and 2.5% fixed, and is one of the few that names solar panels and battery storage explicitly as eligible. Hamilton runs a local improvement charge scheme aimed at building envelope work and heat pumps rather than solar. Guelph’s own programme is not on these lists.
So the money a Guelph homeowner can count on today comes from two places. Ontario’s Home Renovation Savings Program pays up to $10,000 for solar panels and battery storage together. And net metering through Alectra credits your exports at the full retail rate, with credits carrying forward for twelve months.
That leaves financing as the variable you actually control, and it is worth more attention than it usually gets. The gap between a municipal charge at 2% and dealer financing at eight or nine per cent, over a fifteen-year term, is larger than the difference between competing panel brands. With Guelph’s zero-interest loan waitlisted, most Guelph homeowners do not have a subsidised option right now, which makes shopping the second one properly the single most valuable hour in the process.
If you want the Guelph Greener Homes loan, join the waitlist early — as Kingston showed, these programmes come and go.

Guelph solar questions
What solar incentives are available in Guelph?
HRSP ($10K for solar + battery) or net metering (1:1 retail credits).
You choose one – they can’t be combined.
The federal Greener Homes programs are now closed.
How much does solar cost in Guelph?
A typical 9 kW system costs $26,000-$28,000 before incentives.
With HRSP ($5,000 solar rebate), net cost starts at $21,000.
Guelph produces 1,150 kWh/kW annually.
Payback: 9-12 years.
Who provides electricity in Guelph?
Alectra Utilities distributes electricity in Guelph.
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 Guelph?
Alectra Utilities 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 is Guelph's average saving lower than nearby cities?
Because the systems are smaller, not because the sun is worse.
Guelph is modelled at 1,150 kWh per kW a year — the same as Richmond Hill, Vaughan, Whitby, Pickering and Ajax, and within about two per cent of Mississauga’s GTA-leading 1,170.
What differs is the typical system size this page assumes: 9 kW, against 10 kW across most of the Alectra group.
A smaller array saves less and costs less, which is why the payback band of 9 to 12 years matches its neighbours even though the saving does not.
If your own home is larger or you heat with electricity, the $2,050 figure understates your case.
Is there a Guelph solar rebate or city loan?
There is no Guelph solar rebate that we can find, but there is a city loan: Guelph Greener Homes offers a zero-interest home energy loan, plus grants for eligible low-income households.
Loan funding is almost all spoken for and a waitlist is open, so check with the City whether your project qualifies.
For comparison, Better Homes Ontario’s programme listing names Kingston, Ottawa, Toronto and Durham Region — and Kingston’s has since closed to new applications; London runs its own scheme covering solar, and Hamilton’s covers envelope and heat pumps rather than panels.
What a Guelph homeowner can use is Ontario’s Home Renovation Savings Program, worth up to $10,000 for solar panels and battery storage together, plus net metering credits through Alectra at the full retail rate, carried forward for twelve months.
Because the city loan is waitlisted, the financing you arrange yourself is the number most worth negotiating.
