In 2026, residential solar costs between $15,000 to $32,000, between $2.40 and $3.25 per watt, on average. depending on your region, the size of the array, the brand and type of components used, the install labour and warranty coverage, and if installed on a rooftop or ground mount.
Solar power and wind power are both forms of renewable energy. Single-home wind turbines exist, but they are less efficient and do not generate as much electricity as solar panels. A typical turbine for single-home use is about 80 feet tall and must be placed in an area that has high average wind speeds.
Wind turbines can generate power 24 hours a day, whereas panels can only generate power during sunlight hours. Solar power is more popular for homeowners, and wind power is used more at the utility scale.
Most homeowners in Canada can save between $1,500and $3,000 in 2026 by switching to solar. This depends on how much electricity your home uses, the size of your solar array and its coverage of that power needed. It is best to target 100-105% of the amount you need, plus more if you will convert to electric appliances, like a heat pump, radiant floor heat, electric vehicle or an induction range. It will not cover the fixed distribution costs that the utility company charges for being connected to the electricity grid, usually between $35-50 a month.

The roof will be the foundation for solar panels. It is a good idea to ensure that your roof is in good condition before the panels are installed. A rule of thumb is that your roof will last another 10 years before installing. Replacing your roof after the panels are installed is possible, but it will require a "removal and replacement" service, which is available but it will add to your costs. A metal roof that will outlast solar panel life is ideal but not required.
If you have recently replaced your roof with fiberglass shingles, you should contact your manufacturer, review your warranty for specific details.
New solar panels and improvements in technology have increased the lifespan of solar panels to 40 years, with warranty coverage to 25 years. However, all panels regardless of brand will be subject to a small reduction in peak output as they get older, which is important to consider.
The process starts with light (not heat!) from the sun that hits the solar panels. A solar panel is comprised of solar cells, that create an electric field to generate direct current (DC) electricity.
Most houses use alternating current (AC) electricity, so the electricity generated by the panels must be converted to AC using an inverter, a simple and small addition that makes the electricity usable.
A net meter will measure the electricity production and usage and record it for your hydro company.

We have a blog post about this: Considering Solar: Do this first
There is no better place to start than with Solr Solvr! We inform, assess, and when you're ready we can connect you to installers.
Yes! We simplify the solar process: We inform, assess then connect you by contacting verified installers and manufacturers that operate in your area to find the best solution for you.
We only charge a small fee to the installer once you have agreed to go forward. This fee is most often paid for due to the competitive bid for your solar.
Solar panels are surprisingly low maintenance, considering all the Canadian weather they must withstand! Panels should be cleaned a few times a year to maintain high energy output. This can be done by the homeowner themselves. You may also want to clean snow off the panels after an extended snowfall, but when the sun comes out, snow will quickly melt and fall off the tilted panels.
Did you know? Snow reduces solar production by less than 5% annually!

Most Canadians use ‘net-metering’, so the hydro company banks their power generated. Excess energy produced during the day can be stored and saved for nighttime use with a battery system. If you have a "Behind the Meter" design to get Ontario rebates, yo can also attach batteries that allow you to use the electricity generated when you need it.
The cost of home-back up batteries have come down dramatically, while the technology has improved in 2026. Batteries are needed in an ‘off-grid’ setup where there is no connection to an electric grid. Nearly all solar systems in residential neighborhoods are grid-tied. Some grid-tied customers use batteries to use the solar power during 'peak rates' to lower their cost further. They can also be used to power out-buildings like sheds or separate garages, and keep your electricity on when there is a power outage.
With net-metering, you will still have to pay your fixed delivery charge from your hydro company. The offset on your electricity bill depends on the size of your system, the price of electricity, daylight hours, and the size of your bill.
Solar windows are a newer technology where ordinary glass is coated with a transparent photovoltaic layer that converts the light from the sun into usable energy. Solar windows are still in development, and they are not widely available.
The primary benefits of roof mounted systems are that they don’t take up any ground space on the property. They are also cost-efficient and won’t alter the aesthetics of your property.
Ground mounted systems are sometimes used when solar panels on the roof are not suitable. They are easier to maintain and clean, but they take up a lot of ground space and the mounting structure will raise costs.
A grid-tied solar system partners with your local utility to bank your excess electricity generated in summer and provides it back over winter months. It is when you hand over all power generated by the panels to your local utility company, and you receive power through the traditional power grid. “Power banking” covers a 12-month period, and then starts over.
An inverter is necessary in combination with your solar panels to convert DC (direct current) to AC (alternate current) so your home’s power system can utilize it. There are central sine wave inverters or micro inverters that attach to each panel, and there are benefits and setbacks to each.
Net metering is essentially ‘selling’ the power created by solar panels back to hydro companies, and in return you receive a credit that is deducted off your monthly bill. If the credits pay off your entire monthly bill, the remaining credits can be stockpiled and saved for future use for up to 12 months.
Solar panel warranties vary greatly depending on the manufacturer. Most major manufacturers give their products up to a 25-year warranty, but cheaper products often come with a shorter warranty.
There are numerous apps that allow you to see the details of your panel’s status and energy production at any time. The solar app you use will depend on if you use a central sine wave inverter or several microinverters.
No. Solar electricity is generated from the light from the sun, not the heat.
No. When installed by professionals, your roof is guaranteed not to leak. There is minimal impact on your roof’s warranty but check with the roof manufacturer.
Solar does not increase your risk insurance, and it may increase your home value. In Ontario, roof-mounted panels are usually covered by homeowners' insurance. Contact your insurance provider for more details.
The Canada Greener Homes Grant is no longer available for homeowners, but there are provincial and regional/city incentives available in 2026.
Businesses can benefit from 3 incentives to save 40-60% off the cost: Clean Technology Investment Tax Credit, Accelerated depreciation up to 100% and Commercial SaveOn rebates in Ontario, up to $860,000 in 2026.
Ontario currently has no incentives for homeowners looking to install solar panels, but there are incentives offered through the federal government. Check your municipalities’ website for municipal incentives.
We at Solr Solvr recommend lithium-ion batteries, which we think are better value despite their higher price. Gel batteries degrade significantly faster than lithium batteries, and they have a shorter period of operation before having to be charged again.
With the onset of electric vehicles, lithium-ion batteries are coming down significantly in price. For homeowners in Canada looking to install solar panels, we recommend lithium-ion or LiFePo4 (lithium-ion phosphate) batteries. They are lighter, smaller and can be drained down to 10-20% power without damage, whereas lead acid and gel batteries can only be drawn down to 50% safely. LiFePo4 batteries also function better in Canada’s colder climates.
Leasing solar panels is an option for consumers who do not want to pay upfront, but there are important things to consider before agreeing. Firstly, the energy savings will be smaller when compared to buying the system outright. Some panel owners find it difficult to transfer leases.
If you are considering leasing solar panels, have a lawyer review the contract.
Homeowners and business owners should check the CMHC website to see if you qualify for the clean energy renovations loan.
For grid-tied systems, approvals are needed from the municipal planning office as well as your electric utility the hydro company.
If possible, check your monitoring system to see potential points of failure. If the problem persists, contact your installer, manufacturer or certified technician.
There are several reasons for lower output including dirty panels, an obstruction, or issues with the wiring and inverters.
Contact your installer directly to narrow down the source of the problem.
Bring the issue up with your installer before contacting the manufacturer to understand the process. If you are having an issue getting resolution, please contact Solr Solvr.
