Solar panels in Whitby, Ontario: 4 Xolar installs in Whitby
The best-served town in Durham: three programmes, and two of them are Whitby only.
Whitby produces 1,150 kWh per kW a year and pays back in 8 to 11 years, but the reason to read this page is the financing. Whitby homeowners can use the Durham Greener Homes Loan — up to $125,000 at 2% over fifteen years — and are the only people in Durham who can also claim the Weather–ready Rebate, worth up to $5,000. (The Deep Retrofit Rebate, also worth up to $5,000, is fully subscribed and no longer taking new applicants.) Ontario’s rebate of up to $10,000 for solar and battery storage applies on top of all of it.

What 4 real Whitby installs tell us
Aggregated from completed Xolar systems in Whitby — first-hand data, not industry averages.
Whitby energy & net metering
What Elexicon Energy 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). Whitby electricity is distributed by Elexicon Energy. 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.
Elexicon Energy Time-of-Use rates in Whitby
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.
Elexicon Energy 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 Whitby buys.
How your system works behind the meter
Most of a Whitby 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 Elexicon Energy for net-metering credit.

Solar Panels in Whitby, Ontario - Durham Region
Whitby in Durham Region produces 1,150 kWh per kW annually. Elexicon Energy 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 ($5K solar + battery at $300/kWh up to $5K) or net metering available – but not both.
Durham Region Programs in Whitby
The Durham Greener Homes Loan is open and is the largest municipal financing offer on this site: up to $125,000 at 2%, repaid over a fixed 15 years. It covers energy efficiency and weather resiliency work, split 80% / 20% between the two, with an initial disbursement of up to half the approved funds. Because it is a Local Improvement Charge it attaches to the property rather than to you, and transfers to the next owner on sale — worth understanding before comparing it with a personal loan.
Whitby has a rebate on top of that, and no other town in Durham does. The Weather-ready Rebate pays up to $5,000 for eligible weather-ready upgrades and is restricted to Whitby residents. Whitby’s Deep Retrofit Rebate, up to $5,000 for deep energy-efficiency retrofits, is fully subscribed and no longer taking new applicants.
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.
Note: The Canada Greener Homes Grant (closed February 2024) and Greener Homes Loan (closed October 2025) are no longer available.
No Other Town on This Site Has Three Programmes Stacked Like This
Whitby is the best-served municipality in Durham Region, and it is worth setting out exactly what that means before you read a quote.
The Durham Greener Homes Loan is open to you: up to $125,000 at 2% over a fixed fifteen years, repaid through a Local Improvement Charge that attaches to the property and transfers to the next owner on sale. Whitby residents can also claim the Weather-ready Rebate, worth up to $5,000 for eligible weather-ready upgrades, which is restricted to Whitby — no other town in Durham can use it. The Deep Retrofit Rebate, worth up to $5,000 for deep energy-efficiency retrofits, is fully subscribed and no longer taking new applicants.
On top of that sits Ontario’s Home Renovation Savings Program, worth up to $10,000 for solar panels and battery storage together, which is provincial and applies everywhere in the province.
A few caveats keep this honest. The Weather-ready Rebate is aimed at resilience work rather than at solar specifically, so what it covers depends on the upgrades in your project — a solar-only job may not draw on it at all, while a retrofit that includes insulation, a heat pump and solar may. And each programme sets its own eligibility rules, so stacking is a question to put to the programme administrators rather than to assume.
The practical advice is simply to plan the whole retrofit at once rather than doing solar in isolation. Whitby is one of the few places in Canada where doing so is clearly worth the coordination.

Whitby solar questions
What rebates are available in Whitby?
Durham Region homeowners can access Ontario HRSP ($5,000 for solar at $1,000/kW + battery at $300/kWh up to $5,000; heat pumps carry a separate $12,000 maximum).
Note: The Durham Contact your Xolar advisor for the most current programs available.
Who provides electricity in Whitby?
Elexicon Energy distributes electricity in Whitby.
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 Whitby?
Elexicon Energy 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.
What Durham Region programs can a Whitby homeowner use?
Not all three: the Deep Retrofit Rebate is now fully subscribed.
The Durham Greener Homes Loan lends up to $125,000 at 2% over 15 years, repaid through a charge on the property that transfers when you sell.
Whitby residents can also claim the Weather-ready Rebate, up to $5,000, which is restricted to Whitby, so this is still the best-served town in Durham Region.
Ontario’s HRSP applies on top: up to $5,000 for solar and $5,000 for battery storage.
What can a Whitby homeowner claim that the rest of Durham cannot?
One rebate.
The Weather-ready Rebate, worth up to $5,000, is restricted to Whitby residents — no other town in Durham Region can claim it.
Whitby’s Deep Retrofit Rebate, also worth up to $5,000, is fully subscribed and no longer taking new applicants.
On top of that, Whitby homeowners can use the Durham Greener Homes Loan like most of the region, up to $125,000 at 2% over fifteen years, repaid through a charge on the property.
Ontario’s Home Renovation Savings Program adds up to $10,000 for solar panels and battery storage together.
The Weather-ready Rebate targets weather-resiliency work rather than solar specifically, so whether your project draws on it depends on what else it includes.
Should I do solar on its own or as part of a bigger retrofit in Whitby?
In Whitby the case for doing it together is stronger than almost anywhere.
A solar-only project can use Ontario’s Home Renovation Savings Program, worth up to $10,000 for panels and battery storage, and the Durham Greener Homes Loan for financing.
But the Weather-ready Rebate, up to $5,000 and available only to Whitby residents, is aimed at resilience work — weather-readiness measures — so a project that includes those may draw on funding a solar-only job cannot. (The Deep Retrofit Rebate, which covered deep efficiency work, is fully subscribed and no longer taking new applicants.) Each programme sets its own rules, so confirm eligibility with the administrators before counting on any combination.
