Hamilton Solar: Alectra Net Metering and Honest Sizing
Hamilton is served by Alectra Utilities, with solar production around 1,160 kWh per kW a year. It is one of Ontario’s lower–sun major cities thanks to lake–effect cloud and the escarpment, so honest system sizing matters. Ontario’s HRSP adds up to $10,000 in solar and battery rebates, or you can choose Alectra 1:1 net metering instead. The City’s Better Homes Hamilton program finances heat pumps and envelope upgrades (not solar), which pairs well with an HRSP solar claim for a whole–home upgrade. Payback runs about 9 to 12 years.

Hamilton 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). Hamilton 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 Hamilton
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 Hamilton buys.
How your system works behind the meter
Most of a Hamilton 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 Alectra Utilities for net-metering credit.

Solar Panels in Hamilton, Ontario
Hamilton combines industrial heritage with a growing residential solar market. Alectra Utilities distributes electricity with solar production of 1,160 kWh per kW annually. Ontario’s Time-of-Use pricing maximizes solar value 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. Hamilton’s mix of older and newer homes means a site assessment is key to optimal panel placement.
Solar Incentives and Financing in Hamilton
Ontario’s Home Renovation Savings Program (HRSP) offers up to $5,000 for solar ($1,000/kW) plus battery storage at $300/kWh up to $5,000. Solar and battery together can reach $10,000 in HRSP rebates. Solar under HRSP must be sized for load displacement only, so you choose either HRSP or 1:1 net metering, not both.
Alectra Utilities handles Hamilton net metering: residential micro-generation up to 12 kW, with credits carried forward for 12 months.
The City runs Better Homes Hamilton, a property-tax financing program of up to $20,000 for home energy retrofits. Important: it funds heat pumps, insulation and air sealing, not solar or battery storage. A practical Hamilton play is to claim HRSP for your solar and use Better Homes Hamilton to finance a heat pump for a whole-home upgrade. Better Homes Hamilton has run as a pilot, so confirm current intake with the City.
Note: the federal Greener Homes Grant (closed March 2024) and Loan (closed October 2025) are no longer available. As of June 2026.
What Eight Hamilton Systems Say About Sizing Here
The systems Xolar has running in Hamilton are the largest set on any of these pages, and the spread is instructive. They run from 6.885 kW to 14.98 kW with the middle around 12.15 kW, which puts half of them over Ontario’s 12 kW micro-embedded generation threshold. That threshold decides which connection process your project follows: at or under 12 kW it is micro-embedded generation and the shorter route, above it the standard embedded generation process. The Ontario Energy Board raised the ceiling from 10 kW on 1 May 2026, and it applies through Alectra here exactly as it does everywhere else in the province. Hamilton’s housing runs from narrow lower-city lots to large properties in Ancaster and Flamborough, and the sizing follows the roof rather than the postcode. At 1,160 kWh per kW a year, Hamilton is one of the stronger solar cities we serve.

"They provided a very thorough proposal and walked us through it in detail."
"Hired Xolar to install Trina solar panels with Tigo inverters and SMA inverter back in 2022 given that they offered the best return on investment based on all the quotes I had received.After a full month of solar production, very happy to see the system is working as expected. My first Toronto Hydro bill with this net meter arrangement was a credit of 41.31 (all fees included!). Like any project, there were some hiccups along the way, but the team at Xolar resolved all of them to our satisfaction. Looking forward to seeing how the system performs over the next 25-30 years!"
