London energy & net metering
What London Hydro 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). London electricity is distributed by London Hydro. 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.
London Hydro Time-of-Use rates in London
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.
London Hydro 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 London buys.
How your system works behind the meter
Most of a London 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 London Hydro for net-metering credit.

Solar Panels in London, Ontario
London, served by London Hydro, has strong solar production at 1,170 kWh per kW annually. Southwestern Ontario receives more sunshine than the GTA, making London one of Ontario’s better cities for solar ROI.
Ontario’s net metering program credits excess solar at the full retail rate. With Time-of-Use billing, solar earns maximum value during on-peak hours (20.3¢/kWh). HRSP ($5K solar + battery at $300/kWh up to $5K) or net metering available – but not both.
Solar Incentives and Financing in London
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 installed under HRSP must be sized for load displacement only, so you choose either HRSP or 1:1 net metering, not both.
London Hydro handles your net metering: residential micro-generation up to 12 kW with a dedicated online net-metering application and credits that carry forward for 12 months.
BetterHomes London is a City of London financing program (launched 2026) that funds eligible home energy upgrades through a charge on your property tax of up to $40,000, repaid over 10 to 20 years and transferable if you sell. Confirm the current list of eligible measures with the City. You can also check your own roof’s solar potential with the City’s free MyHEAT Solar tool.

What London homeowners say
"We are happy with our roof top solar panels from Xolar. Lauren was a great help as our project manager. Vivek and John also helped us with our many questions. The project was finished on time. I wouldn’t hesitate to recommend Xolar."
"Had a very complex installation, quite large with lots of features, with the solar array powering two homes. Took a while to complete and there were a few technical glitches along the way but they were taken care of. Quality of product and Technicians was excellent. It would be 5 stars if there was better communications. Several times I had to repeat emails trying to get answers."
"I had my solar system installed by Xolar and I’m extremely satisfied with both the hardware and the overall setup. The system delivers immediate savings on my Hydro bill and is performing better than I expected, even under winter conditions. The hardware layout is clean, thoughtfully designed, and integrates seamlessly with my existing electrical system.The project timeline was solid: I placed my order in August, the installation took place over the winter, and everything was fully completed by April, including all permits and approvals from the city. The only hiccup in the entire process was a hardware shortage during the ordering phase, which required me to follow up a few times. That delay was frustrating, but ultimately handled well.A special mention goes to Lauren, who has been a great point of contact from start to finish. She is responsive, clear in her communication, and consistently advocated on my behalf to resolve issues and push past any delays. Having someone like Lauren to talk to made a big difference and kept my confidence in the project high.Overall, I would definitely recommend Xolar to anyone considering a solar installation. Once the hardware arrived, everything moved smoothly, the system was set up correctly the first time, and the performance and savings so far have exceeded my expectations."
"Loved the information that was shared during the process. Xolar was better right from the start. They provided more information about the entire process then the other two businesses that I received quotes from. Installation was quicker than expected there was a couple small issues but they were looked after quickly. Solar has now been running for 4 months and starting to see reduced energy bills. Very impressed!"
"Our solar panels were installed and are working great. Lots of great communication from Xolar throughout the process to ease our worries."
"We were, overall, delighted with the solar panel solution from Xolar. The process, from first consultation, to operation and receiving the Greener Homes Loan took almost exactly 6 months, which we were very happy with given we started to process in December.We were quite concerned about the look of the panels as our South facing roof faces the street and we live in a neighbourhood with a lot of nice homes. But we were really delighted with how they look - they just blend in nicely with the roof and many of friends have said they hardly noticed them. They also present a modern appearance.As you can see, the panels are only over the garage but that is estimated to be sufficient to cover around 90% of our hydro use, and we use only electricity, with geothermal heating and cooling, and have an electric car. So far, the hydro generation matches the estimates provided by Xolar.The initial presentation of the solution, by Chris Isidori, was very thorough, and he was available to answer all of my questions. The Xolar website is also excellent and there are many customer solutions listed there to read about, and speak to their experience. The installation team were a joy to work with - they arrived on time, were extremely pleasant, completed the entire install in less than 2 days, and cleaned up very well at the end.Overall, the solution exceeded our expectations and we are very much enjoying making a contribution to the energy grid while saving money in the long term. I wouldn't hesitate to recommend Xolar if you are considering installing a solar array on your home."
