Solar panels in Niagara Falls, Ontario
Fifth-best sun in Ontario, and a utility headquartered ten minutes from the falls.
Niagara Falls is modelled at 1,180 kWh per kW a year — the fifth–highest figure of the 35 Ontario cities on this site, behind Chatham–Kent, Windsor, Ottawa and Sarnia. Payback runs 9 to 11 years. What Niagara Falls does not have is a municipal loan or rebate of its own, so the arithmetic here rests on the provincial rebate and net metering.

Niagara Falls energy & net metering
What Niagara Peninsula 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). Niagara Falls electricity is distributed by Niagara Peninsula 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.
Niagara Peninsula Energy Time-of-Use rates in Niagara Falls
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.
Niagara Peninsula 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 Niagara Falls buys.
How your system works behind the meter
Most of a Niagara Falls 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¢/kWh. Only the surplus flows past the meter to Niagara Peninsula Energy for net-metering credit.

Solar Panels in Niagara Falls, Ontario
Niagara Falls produces 1,180 kWh per kW annually – above the Ontario average thanks to the Niagara Region’s moderate climate. Niagara Peninsula Energy 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.
Fifth-Best Sun in Ontario — Behind Chatham-Kent, Windsor, Ottawa and Sarnia
Of the 35 Ontario cities on this site, five are modelled above 1,175 kWh per kW a year. Chatham-Kent leads at 1,210, then Windsor and Ottawa at 1,200, Sarnia at 1,190, and Niagara Falls at 1,180. Everything else in the province sits below that, including the whole of the GTA.
The gap is not dramatic — a Niagara Falls panel produces about 2.5 per cent less than a Chatham-Kent one — but the direction matters when you are comparing quotes with relatives elsewhere in Ontario. Against Sudbury at 1,050 the same panel produces roughly 12 per cent more here. Against Oshawa at 1,140, about 3.5 per cent more.
What that buys is a payback of 9 to 11 years, among the shorter ranges in the province, on an average system of 10 kW saving around $2,100 a year.
The honest caveat is what Niagara Falls does not have. London homeowners can borrow up to $40,000 from their city at 2.5% to pay for solar; Durham Region residents can borrow at 2%. We could find no equivalent municipal loan or rebate covering solar in Niagara Falls or the wider Niagara Region — Niagara Renovates, the regional programme people most often hear about, is an income-tested repair programme for affordable housing rather than a retrofit loan. So the money here comes from one place: Ontario’s Home Renovation Savings Program, up to $10,000 for solar panels and battery storage together, plus the value of the electricity you stop buying.
Given the sun, that is usually enough. But it does mean a Niagara Falls quote should be compared against ordinary financing rather than a subsidised municipal rate.
Connecting to Niagara Peninsula Energy: Seven Steps, and 12 kW Is the Dividing Line
Niagara Falls is distributed by Niagara Peninsula Energy Inc., whose engineering department sits at 7447 Pin Oak Drive in Niagara Falls itself. NPEI splits generation connections at 12 kW: systems of 12 kW or less follow a micro path, and anything larger is treated as a small, mid-sized or large embedded generator, which is a slower and more involved process. Almost every residential rooftop falls on the micro side of that line.
NPEI publishes the sequence as seven steps: a preliminary consultation information request, then the micro DER application, then a site visit by an engineering technician, then the net meter connection agreement and offer to connect, then design and build, then commissioning and a witness test, and finally the connection itself.
Two details are worth drawing out. The first is the engineering technician’s site visit, which happens before you build — NPEI assesses and approves every distributed energy resource connection on its system, and it publishes a DER hosting capacity methodology to work out how much generation a given part of the grid can take. The second is that NPEI follows Hydro One’s technical interconnection requirements rather than writing its own, so the equipment standards your inverter has to meet are the provincial ones.
In practice your installer runs this process. What it means for you is timing: there is a site visit and a witness test between signing and generating, and neither is negotiable. A system is connected when the utility says it is connected.

What Niagara Falls homeowners say
Swipe for more reviews →
"I was interested and curious in solar panels. I had researched and had quotes from a few providers. Xolar took the time to explain to me the process (without talking down to me), and clearly laid out how to manage the Canada Green Homes Loan. I never had to wait more than a day to an answer to any question I had during the installation process. I found Xolar to be professional and competent, and the organization cared more about quality of product then just making a profit."
"The XOLAR Sales teach and tech support group were easy to deal with and provided all the information needed to make our decision."
"Xolar rep is very knowledgeable about solar product and the government rebates that can help make the project happen. Spencer was able to answer all my questions and made the decision to proceed with the application an easy one."
"Our solar panels were installed and are working great. Lots of great communication from Xolar throughout the process to ease our worries."
"Spoke with a representative. Very pleasant and professional.all representatives of the team were helpful, courteous and professional. I highly recommend Xolar"
"They provided a very thorough proposal and walked us through it in detail."
Niagara Falls solar questions
Is Niagara Falls good for solar?
Yes. 1,180 kWh/kW is above the Ontario average.
The Niagara Region’s moderate climate supports strong year-round solar performance.
HRSP ($10K for solar + battery) or net metering available.
What solar rebates are available in Niagara Falls?
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 Niagara Falls?
Niagara Peninsula Energy 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 Niagara Falls?
Niagara Peninsula 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, the net metering system size threshold was raised to 12 kW for residential customers.
Note: Solar under HRSP cannot use net metering.
Is there a Niagara Falls or Niagara Region rebate for solar?
We could not find one.
Neither Niagara Falls nor the wider Niagara Region appears to run a municipal loan or rebate covering solar, which is a real difference from London, where the city lends up to $40,000 at 2.5%, or Durham Region, where the loan is 2%.
The regional programme most often mentioned, Niagara Renovates, is an income-tested repair programme for affordable housing rather than a retrofit loan for solar.
That leaves Ontario’s Home Renovation Savings Program, worth up to $10,000 for solar panels and battery storage together, and the credits you earn through net metering with Niagara Peninsula Energy.
Given that Niagara Falls has the fifth-best modelled sun in the province, that is usually a workable position — but it is worth knowing before you compare a quote here against one from London.
How long does a net metering connection take in Niagara Falls?
Niagara Peninsula Energy runs a seven-step process, and the length is driven by two steps you cannot skip.
Before you build, an engineering technician visits the site, and NPEI’s engineering department assesses and approves every distributed generation connection on its system against a published hosting capacity methodology.
After you build there is a commissioning and witness test before the final connection.
Between those sit the micro DER application, the offer to connect and the net meter connection agreement.
Your installer handles the paperwork, but the practical consequence is that panels on the roof do not mean a system that is generating — the utility connects last.
