Overall Solar Rating

Overall Provincial Solar Rankings

We’ve ranked Prince Edward Island as being Canada’s third worst province for solar power in 2019. PEI doesn’t score near last for any one indicator, but it’s one of the few provinces that doesn’t score very high for any either. Overall it performs in the mid range of almost every factor we ranked.

Curious to see how and why we rank the provinces the way we do? Check out the Solar Rankings Page to find out more.


Basic System Information

When thinking about solar power, the first questions that often come to a person’s mind are:

  • “How big does my solar system need to be?”
  • “Can I completely offset my electricity usage?”
  • “How much will it cost?”

This section is intended to answer these basic questions before going into the details about installing solar in Prince Edward Island.

Sizing Your System

Determining the size of system you need is as simple as knowing how much energy you use during the course of a year. Your monthly Maritime Electric Hydro Bill will show your usage (in kWh) similar to the photo below:

Maratime Electric Electricity Bill

You’ll need to figure out how much energy you use in a year by adding up the amount shown for 12 consecutive months. Note that taking one month and multiplying by 12 won’t work because energy use fluctuates depending on the season.

After you know how much energy you use, you can easily calculate the size of the solar power system that you’ll need by using the following equation:

Size of system needed (in kW) = yearly energy use (in kWh) / 1,104h

(where 1,104h equals the annual average equivalent of full sunlight hours in Prince Edward Island)

So let’s pretend you added up your power bills and determined that you use 10,000kWh over the course of a year, you would then do the above calculation and determine that you need a 9.06kW solar panel system!

10,000kWh / 1,104h = 9.06kW

System Location

Now that you know the size of your system, you’ll want to determine the best place to put it. Most residential homeowners in Prince Edward Island put the solar panels on their roof, while most rural homeowners put them on the roof of their house, shop, or on the ground in their yard.




If you’re putting solar panels on your roof, you should know:

  • A south facing roof is best, east and west facing are good, north facing is just OK
  • Output on panels are guaranteed for 25 years, so you may need to replace your shingles (or entire roof) before installing
  • If you’re concerned about snow, know that roof mounted panels are harder to clean off
  • Your roof’s pitch (slope) is not the most optimal angle for solar production

If you’re putting solar panels on the ground, you should know:

  • These systems are more expensive upfront due to piling requirements, mounting materials, and power line trenching…
  • … But are cheaper in the long term because they are more efficient (see next point)
  • They can be easily placed to avoid shading, to the optimal direction (south), and to the optimal angle (~45°)
  • Systems can be much larger than roof mounted ones

Cost of Installation

Cost of Solar Power Canada 2019

The last piece of basic information that you’ll want to know is an approximation of how much your system will cost. To calculate this you’ll need to know the size of the system you plan to install (see previous section).

The rough calculation is simple. Just take the size of your system and multiply it by the $2.93/Watt (the average cost of installing a solar system in PEI). Using the example from the sizing section, we can see that a 9.06kW system would cost approximately $26,546 to install.

System cost = size needed x cost per installed watt

= 9,060Watts x $2.93/Watt

= $26,546

Please note that the exact price of the system depends on several factors including the system size, the quality of equipment used, and the complexity of the job. Even the range in the chart above is just for the average – installation prices can easily go as high as $3.50/Watt for premium equipment installed by the highest quality installers.

Solar Incentives

Solar Energy and Energy Efficiency Incentives Canada

Major Program: EfficiencyPEI

Savings On: Generation & Efficiency Equipment

Prince Edward Island doesn’t have any specific solar rebates, however it does have a few energy incentives available to homeowners. This section briefly covers the energy incentives available to homeowners. A more in-depth explanation of each can be found on the Prince Edward Island Incentives Page.

Solar Rebates & Tax Credits

As mentioned, there are no solar rebates or tax credits currently available for PEI homeowners.

Other Energy Incentives

However, Prince Edward Island has a number of other energy incentives available:

Businesses can now use the Federal Tax Provision for Clean Energy Equipment to fully expense their solar system. This means a CCA rate of 100% and the abolishment of the first year rule.

Remember, energyhub.org also has a special solar incentive. It’s not huge, but it’s easy to claim – just send us a picture of your installation or purchase agreement with one of our certified energy installers. Full details on the energyhub.org Cash Incentive Page.

Regional Geography

Solar Irradiation and Energy Use Canada

Production Efficiency: 1104kWh/kW/yr

Average Energy Use: 106GJ/yr

In terms of available natural resources and homeowner energy demand, Prince Edward Island is one of the best provinces in the country to install solar. This section briefly covers the amount of sunlight that PEI receives (solar irradiation) as well as energy demand from homeowners.

Solar Irradiation

Prince Edward Island has the second highest potential to produce solar energy in all of Canada, receiving more solar irradiation than most other provinces!

According to data from National Resources Canada, the average solar system in Prince Edward Island can produce 1104kWh of electricity per kW of solar panels per year.

Here is how much an average solar system can produce each month, as well as the solar irradiation potential map for PEI:

Monthly Solar Irradiation Data Prince Edward Island

Solar Energy Map Prince Edward Island

This yearly average decreases as you move east in the province and increases as you move west. For example:

  • A 1kW solar system in Charlottetown would produce about 1,103 kWh/yr
  • A 1kW solar system in Summerside would produce about 1,125 kWh/yr
  • A 1kW solar system in Stratford would produce about 1,100 kWh/yr
  • A 1kW solar system in Cornwall would produce about 1,106 kWh/yr
  • A 1kW solar system in Montague would produce 1,087 kWh/yr

Total Energy Demand

The average household in Prince Edward Island uses 106GJ of energy per year – that’s the equivalent of 29,400 kWh of electricity! And although most homes only use about a third of that (because of gas heating), the number still demonstrates a strong need for energy generation and energy efficiency technologies.

In sum, at least for the average homeowner, it is completely possible to offset one’s yearly power bill with a solar system.


Electrical Utilities

Electricity and Solar Setup Fees Canada

Variable Costs: $0.14/kWh

Fixed Costs: $25/mo

Setup Fees: None

Prince Edward Island is a decently attractive province to switch to solar power in terms of utility related factors. This section covers how the costs of electricity as well as solar setup fees affect of the feasibility of solar in PEI.

Variable Electricity Costs

On Grid Energy Storage

Variable electricity rates determine the maximal amount of money that can be saved by switching to solar – ie. they represent the portion of your power bill that goes to zero when you don’t use any energy. Thus the moderate rates in Prince Edward Island ($0.14/Watt) mean that the average homeowner has some savings potential with solar.

Fixed Electricity Costs

On the other hand, fixed electricity costs are not so good because they don’t disappear even if you switch to solar power – you’ll pay them as long as you remain connected to the grid. However, this isn’t necessarily a bad thing – $25/mo is a small price to pay for using the grid as your energy back-up and virtual energy storage device!

The only way to completely remove your fixed costs are to go off the grid, something most homeowners don’t do due to the large price and maintenance costs of battery storage. Plus, disconnecting from the grid means you won’t be able to participate in a net metering program.

Net Metering Policy

Electricity Smart MeterNet Metering is one of the most important policy mechanisms that makes solar a feasible energy generation option. Net Metering essentially means that you can send the excess energy that you produce (during the day the summer) back to the electricity grid and earn credits for that energy at the same retail rate that you buy it for.

These credits can then be used to offset your energy usage during times when your solar system doesn’t produce as much energy as is needed (during the night and winter). Without this mechanism, you would need to purchase an extremely costly set of batteries.

Prince Edward Island’s Net Metering Policy allows for systems up to 100kW in size to be connected to the grid for net metering, however it’s very important to note that credits in PEI expire on your system’s anniversary date, thus you’ll want to work closely with your installer to make sure your system perfectly matches your energy usage.

Solar Setup Fees

Prince Edward Island’s Net Metering Policy also dictates that you don’t need to pay for an interconnection study or a bi-directional meter when you switch to solar power. This is opposed to many provinces like Saskatchewan and Manitoba, where interconnection and bi-directional meter fees can reach over $1000!




Access To Solar

Solar Cost Financing and Installer Access

Upfront Cost: $2.93/Watt

Financing: Energy Loan

Installer Access: Medium

A completely new section to this year’s Prince Edward Island solar guide, Access to Solar explores the major accessibility factors in the province.

Cost of Installation

The upfront cost of installation is obviously one of the largest factors that determines whether or not a person is going to switch to solar. The current prices in Prince Edward Island range from $2.50-$3.50 with the average price being somewhere around $2.93.




The price changes depending on a variety of factors:

  • The size of system required (larger systems are cheaper on a per Watt basis)
  • The complexity and/or specific requirements of the job
  • The type and quality of equipment used
  • The quality of the installation company

Remember, you can easily calculate the total estimated cost of your system in the Basics Section at the top of this page.

In general, aiming for the cheapest price shouldn’t be your goal. Remember that the energy output on solar equipment is guaranteed for 25 years, so you want to make sure that your installation job is good enough to support that. You’ll also want to be sure that the company you choose will be around in 5 to 10 years from now in case you need service or warranty work done.

PACE Financing

Solar and Energy Financing Options Canada

Property Assessed Clean Energy (PACE) is an innovative financing option that allows you to cover the entire upfront cost of your solar system (or energy efficiency upgrades) with a $0 down, long amortization period, low interest ‘loan’.

However, unlike a typical loan, this loan is attached to your property (not you) and is paid back alongside your property tax bill as a Local Improvement Charge (LIC). The only eligibility is that you need to own a certain percentage of your property.

Unfortunately, PEI does not have any PACE financing options available.

Other Financing Options

Obviously though, PACE is not the only way to finance a solar system. Systems can be financed by cash, bank loans, installer financing, home equity loans, a home equity line of credit, a mortgages (for new builds), or through energy loans.

Several options exists for Prince Edward Island homeowners:

Access to Installers

The final category that we ranked for this year’s Prince Edward Island solar guide is the access to reputable and high quality solar installers. And fortunately, PEI has decent access to installers with some coming over from New Brunswick as well!
