Solar panels in Vaughan, Ontario: 4 Xolar installs in Vaughan
Solar for Woodbridge, Thornhill and Kleinburg roofs — Alectra net metering, honestly sized.
Vaughan roofs run large, and it shows in the systems: some of the arrays Xolar has installed here cross Ontario’s 12 kW micro–embedded generation threshold, which changes the connection route. At 1,150 kWh per kW a year, a Vaughan system does not need to be oversized to cover a big bill.

What 4 real Vaughan installs tell us
Aggregated from completed Xolar systems in Vaughan — first-hand data, not industry averages.
Vaughan 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). Vaughan 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 Vaughan
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 Vaughan buys.
How your system works behind the meter
Most of a Vaughan 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 Vaughan, Ontario
Vaughan’s newer housing stock and larger rooftops make it ideal for solar. Alectra Utilities serves the area with solar production of 1,150 kWh per kW annually. Newer construction often has better roof orientation for solar installations.
Ontario’s net metering program credits excess solar at the full retail rate. HRSP ($5K solar + battery at $300/kWh up to $5K) or net metering available – but not both. Your Xolar advisor can help determine which option provides the best return.
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 (about 16.7 kWh of storage reaches the cap)
- 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 (closed February 2024) and Greener Homes Loan (closed October 2025) are no longer available.
Half of Vaughan's Systems Cross Ontario's 12 kW Line
Ontario treats 12 kW or less as micro-embedded generation and runs it through a shorter connection process — a ceiling the Ontario Energy Board raised from 10 kW on 1 May 2026. Cross that line and the project follows the standard embedded generation route instead. Alectra applies it here, as every Ontario utility does. In Vaughan that is not a theoretical concern: of the systems Xolar has installed across Woodbridge, Thornhill and North York, two are over the threshold — 12.15 kW and 12.87 kW — and two sit under it at 6 kW and 10.625 kW. Larger homes in Kleinburg and Woodbridge are exactly where a design lands near the line, and a 12.87 kW array is a different application from a 11.9 kW one. It is a question worth settling at design time rather than after you have signed.
Vaughan's Saving Is Driven by the Size of the Bill, Not the Strength of the Sun
Vaughan is modelled at 1,150 kWh per kW a year. That is respectable rather than remarkable — mid-table for Ontario, level with Guelph, Richmond Hill, Whitby, Pickering and St. Catharines, and below the southwestern group led by Chatham-Kent at 1,210.
Yet the average saving quoted here is $2,300 a year, higher than Hamilton’s $2,100 and Brantford’s $2,100, both of which get better sun at 1,160. The explanation is not meteorological. It is that Vaughan households consume more electricity, so the systems built here are larger — the page assumes 10 kW as typical, against 9 kW for Hamilton and Brantford — and a larger system displaces more.
This is the single most useful thing to understand before reading a quote. Two figures get quoted at you: how much sun your city gets, and how much you will save. The first is a property of the place and you cannot change it. The second is mostly a property of your household, and it is why a neighbour’s saving is a poor guide to your own. A large Kleinburg house with a pool pump and two electric cars and a Thornhill townhouse on the same street grid will get very different answers from the same installer.
Payback here runs 9 to 11 years, slightly shorter than Hamilton or Brantford despite the weaker sun, for exactly the same reason — a larger system offsetting a larger bill.

Vaughan solar questions
Is Vaughan good for solar?
Yes.
Newer homes with larger roofs are ideal. 1,150 kWh/kW production.
HRSP ($5K solar + battery at $300/kWh up to $5K) or net metering available through Alectra Utilities.
What solar rebates are available in Vaughan?
Ontario’s HRSP provides up to $5,000 for solar ($1,000/kW) + battery storage at $300/kWh up to $5,000.
Important: HRSP solar cannot use net metering – customers must choose one or the other.
The federal Greener Homes Grant and Loan programs are both closed.
Who provides electricity in Vaughan?
Alectra Utilities distributes electricity in Vaughan.
Ontario’s Time-of-Use rates: 9.8¢ off-peak, 15.7¢ mid-peak, 20.3¢ on-peak (OEB RPP, Nov 2025-Oct 2026).
The Ontario Electricity Rebate provides a 23.5% discount.
How does net metering work in Vaughan?
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.
Do Vaughan homes need a system over 12 kW?
Some do.
The systems Xolar has installed in Vaughan land on both sides of Ontario’s 12 kW micro-embedded generation threshold.
It depends on your roof and your consumption, not on the neighbourhood.
Crossing 12 kW is not a problem — it just means the standard embedded generation process rather than the micro route.
Why does Vaughan save more than cities with better sun?
Because the saving depends on the bill more than on the sunshine.
Vaughan is modelled at 1,150 kWh per kW, below Hamilton and Brantford at 1,160, but the average saving quoted here is $2,300 a year against $2,100 in both of those cities.
The difference is system size: this page assumes a typical 10 kW system in Vaughan against 9 kW in Hamilton and Brantford, because households here consume more.
It is also why payback is slightly shorter at 9 to 11 years.
The practical lesson is that a neighbour’s savings figure tells you little about yours — what a system is sized to is your consumption, your roof and your shading.
