Average Cost of Solar Panels In Canada 2018

The average cost of solar power system in Canada is between $15,000 and $30,000 (Click here to see cost breakdown per province). This ranges applies for a 7,500kW system (what a normal house needs) but changes depending on the size of system required, your eligibility for rebates and tax credits, and even on the province that you live in. This page will cover everything you need to know to allow you to calculate the cost of solar power for your home or acreage.

General Cost Information

Determining the cost of installing solar power on your home ultimately comes down to two main factors:

  1. The cost of the system (per watt)
  2. The size of the system needed (in watts)

The first factor is easy, all you need to do is ask “How much does an installer charge per installed watt?”. Simply reference the pricing chart on this page.

For the second factor, you’ll need to do an easy calculation using your yearly electricity usage and how much sunlight you get in your province (again, there is a sunlight chart on this page). See the System Size Requirements section of this page to complete the calculation.

Cost Per Installed Watt

As stated, the cost per installed watt is one of just two pieces of information that you need to determine the total cost of your system (the other is the system size).

Here is the average cost per installed Watt broken down by province*:

British Columbia$2.25-$3.75/Watt
New Brunswick$2.50-$4.00/Watt
Newfoundland & LabradorN/A
Northwest Territories$2.00-$3.50/Watt
Nova Scotia$2.00-$3.50/Watt
Prince Edwards Island$2.50-$4.00/Watt
Yukon Territory$2.00-$3.50/Watt

As a general rule, a system in your province will:

  • Be priced at the highest end of the range if sized less than 15 kW
  • Be priced in the middle of the range if sized between 15 and 30 kW
  • Be priced at the lowest end of the range if sized greater than 30 kW

Now you just need to know your system’s size! Jump to the Sizing Section now!

Rebates & Tax Credits

Solar Power Rebates and Tax Credits Canada

Depending on which province you live in, you may be eligible to reduce the cost of your system by taking advantage of a utility or provincial rebate or tax credit program. For a general overview of rebates you can visit the Solar Power Incentives Page or you can read about your potential rebates in-depth on your province’s Complete Solar Power Guide.

Performance Payments

Net Metering Canada

Another important piece of information that you’ll likely want to know is how much your utility provider is willing to pay you for the energy that you produce (if you want to stay on the grid). Some utilities (like BC Hydro) will pay you for excess power that you produce, while other (like SaskPower) will only allow you to reach net zero. Complete information about performance payment programs (often called net metering or net billing) can be found on our Solar Power Incentives Page or in your province’s Complete Solar Power Guide.

System Size Requirements

As mentioned, there are just two pieces of information that you need to determine how much installing solar power will cost for your home or acreage:

  1. The cost of the system (per watt)
  2. The size of the system needed (in watts)

The section is all about determining the size of the system you need.

Energy Usage

Solar systems are sized based on the energy output that’s required. Thus, you’ll need to determine how much energy you use over the course of a year (in units of kWh) by adding up the amount shown on your power or hydro bill.

All electricity bills are slightly different, but let’s take this one from Manitoba Hydro as en example. You can easily see that this customer used 86 kWh in the month of October:

Manitoba Hydro Bill

Go ahead and add up your bills for 12 consecutive months to determine your yearly usage. This number is typically in the range of 7,500 to 10,000 kWh for a normally sized residential home.

Energy Output

The next thing you need to know is how much energy your panels can produce based on the area that you live in. Output is based purely on the amount of equivalent full sunlight hours that you get during the year. The numbers that we have listed below account for normal weather variations (clouds, rain, etc.)

Here is the annual average equivalent of full sunlight hours broken down by province:

  • Alberta (1,301 hours)
  • British Columbia (1,064 hours)
  • Manitoba (1,293 hours)
  • New Brunswick (1,140 hours)
  • Newfoundland and Labrador (943 hours)
  • Northwest Territories (1,637 hours)
  • Nova Scotia (1,068 hours)
  • Nunavut (1,116 hours)
  • Ontario (1,195 hours)
  • Prince Edward Island (1,109 hours)
  • Quebec (1,153 hours)
  • Saskatchewan (1,336 hours)
  • Yukon (971 hours)
  • Canada Average (1,132 hours)

Final Calculation

Now that you know both your annual energy usage and the average annual full sunlight hours that your house gets, you can calculate the size of the system you need with the following equation:

Size of system needed (in kW) = yearly energy use (in kWh) / annual average equivalent of full sunlight hours (in hours)

So let’s pretend you added up your power bills and determined that you use 10,000 kWh in the course of a year, and you lived in the province of Ontario which receives an annual average of 1195 full sunlight hours per year. You would do the above calculation to determine that the size of the system you need is 8.37 kWh!

(10,000 kWh / 1,195h = 8.37 kW)

This number can then be multiplied by the estimated cost per watt quoted in the pricing table above to get your final price! Note that because this system is less than 15 kW, we will use the upper end of the estimated price range

This means that a 8.37 kW system would cost between $27,202 and $33,480 in Ontario (before rebates or tax credits).

(8,370 Watts * $3.25-$4.00/Watt = $27,202-$33,480)

I think what you meant to say is that the average home requires a system size of 7500 Watts, not 7500 kW. Also, I think its best to keep units consistent (especially when comparing costs province to province). An important factor to include in energy production calculations is soiling losses (like snow cover in winter months). This plays a major role in total annual energy production and payback. Anyone seriously looking into solar, beware of… Read more »


It would be nice if this website either provided a list of residential solar panel installers for each province and territory or provided a link for the same. So far I have yet to find this information in one location.

Does the capacity needed include the extra capacity to meet requirements during overcast days or short days in winter? You’ve priced a system based on grid usage correct? But if panels are only producing 20-30% of their maximum capacity through out their lifetime, you’d need to install 4 times the required capacity to actually get the capacity you need on demand and then double or triple that to allow batteries to charge for night use.… Read more »
