# Cost of Solar Power In Canada 2019

The average installation cost of solar power in Canada is $3.07/Watt, or $23,000 for a 7.5kW system (specific price per province in chart below). However, the cost of solar power changes depending on the size of the system required, your eligibility for solar incentives, the type of equipment used, and even on the province that you live in.

This page covers everything you need to very accurately calculate the cost of solar power for your home or acreage. Read from top to bottom or jump to your preferred section below:

## General Cost Information

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

- The cost of the system (per watt)
- The size of the system needed (in watts)

The first factor is easy, all you need to do is determine how much does an installer charge “per installed watt”. The second factor requires you to do a simple calculation that takes into account your yearly electricity usage and how much sunlight your province gets on average.

## 1) 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 solar system.

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

Alberta | $2.77 – $3.02/Watt |

British Columbia | $2.52 – $2.77/Watt |

Manitoba | $2.63 – $3.13/Watt |

New Brunswick | $2.89 – $3.64/Watt |

Newfoundland & Labrador | $3.50 – $4.50/Watt |

Northwest Territories | $2.50- $3.50/Watt |

Nova Scotia | $2.63 – $3.13/Watt |

Nunavut | $3.50 – $4.50/Watt |

Ontario | $2.28 – $2.78/Watt |

Prince Edward Island | $2.56 – $3.31/Watt |

Québec | $2.37 – $3.12/Watt |

Saskatchewan | $3.05 – $3.30/Watt |

Yukon Territory | $2.50- $3.50/Watt |

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

- Be priced higher than the indicated range for premium equipment and installers, or if it’s sized below 7.5kW
- Be priced lower than the indicated range for standard equipment and discount installers, or if it’s sized greater than 7.5kW

## 2) System Size Requirements

Sizing your solar system requires two pieces of information:

- Estimated Energy Usage
- Estimated Energy Output

### 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:

Go ahead and add up your bills for 12 consecutive months to determine your yearly usage. This number typically ranges from 7,500 to 15,000kWh for a normal gas-heated 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.

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

- Alberta (1,276 hours)
- British Columbia (1,004 hours)
- Manitoba (1,272 hours)
- New Brunswick (1,142 hours)
- Newfoundland and Labrador (949 hours)
- Northwest Territories (1,064 hours)
- Nova Scotia (1,090 hours)
- Nunavut (1,092 hours)
- Ontario (1,166 hours)
- Prince Edward Island (1,104 hours)
- Quebec (1,183 hours)
- Saskatchewan (1,330 hours)
- Yukon (965 hours)
- Canada Average (1,126 hours)

## Final Cost 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 over the course of a year. Let’s also pretend that you live in Ontario which receives an annual average of 1166 full sunlight hours per year. You would do the above calculation to determine that the size of the system you need is 8.58kW!

(10,000kWh / 1,166h = 8.58kW)

This number can then be multiplied by the estimated cost per watt quoted in the pricing table above to get your final price!

**This means that a 8.58 kW system would cost between $19,562 and $23,852 in Ontario.**

(8,580 Watts * $2.28-$2.78/Watt = $19,562-$23,852)

Solar panels still seem really expensive. Doing the calculation shows I’d need 13,000kws so the cost would be roughly $30,000-$40,000. While I understand the labour costs of installation, what I don’t get is why solar panels don’t seem to be coming down in price. I’m no engineer. But somebody managed to get a 100 inch television to be only a few cm thick and I don’t understand why we can’t seem to bring the cost… Read more »

His how much is a 400 watts solar panel

I have a 10 KW system in Southern Ontario that generated on average 9,100 kwh/year for 2017 and 2018. Using the equation above, that works out to only 910 hours of equivalent sunlight, which is 256 hours or 22% less than the above-stated 1,166 average. Either those were really cloudy years, or that average is suspect.
