Congratulations! You’ve found the ultimate guide for going solar in Prince Edward Island!

Canadian Solar Power Rankings

Prince Edward Island is currently ranked the #2 province in the country for installing a solar power system, scoring as one of the best provinces for cash rebates and utility-related factors.

This page contains all relevant information about installing solar in PEI including utility policies, system financing, solar incentives, and natural factors – updated as of May 1st, 2021.

The guide begins by answering the two most common questions about solar systems, then it explores each solar ranking factor.

Common Solar Questions

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

  • “How big does my system need to be?”
  • “How much will it cost?”

You can answer these questions in three basic steps:

1. Sizing Your System

To determine the size of system that you need, you only need to know 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 can calculate your annual energy by adding up the amount shown for 12 consecutive months. Don’t make the mistake of multiplying a single month by 12 – usage fluctuates greatly depending on the season.

You can calculate the size of the solar power system that you’ll need with the following equation:

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

(annual average ‘equivalent full sunlight hours’ in Prince Edward Island = 1,104h)

For example, let’s pretend that 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

2. Physical Sizing

Now that you know the size of your system in units of kW, you can determine how much space the system will require by converting it to units of sqft.

The average solar panel is approximately 18sqft in size (including some buffer room for racking and spacing) and produces about 300watts of power.

The equation to calculate the space that your solar system require is again simple:

Physical space required = size of system needed (in kW) / size of panel (in kW) * physical size of panel (in sqft)

(average size of panel = 0.3kW, average physical panel size = 18sqft)

Let’s continue from the previous section and assume that you need a 9.06kW system. You would do the above calculation and determine that you need 544sqft of space to install your system!

9.06kW / 0.3kW * 18sqft = 544sqft

(note that 300watts equals 0.3kW)

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

  • A south facing roof is best, east and west facing are good, but north is not great
  • You may need to replace your shingles (or entire roof) before installing – because panels are guaranteed for 25 years!

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

  • These systems are more expensive upfront due to piling, mounting , and trenching requirements
  • They are more efficiency because they can be easily placed to the optimal direction (south), the optimal angle (~45°), and to avoid shading
  • Thus, these systems are more efficient and have better lifetime IRRs and NPVs.

Most residential homeowners in Prince Edward Island put solar panels on their roof. Rural property owners put systems on the roof of their house or shop – or on the ground in their yard.

3. System Costs

Cost of Solar Power Canada

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 just need to know the size of the system in units of kW.

The rough calculation is simple. Just take the size of your system and multiply it by the $3.03/watt – the average cost of installing a solar system in Prince Edward Island.

You can calculate your total system costs with the following equation:

System cost = size of system needed x cost per installed watt

Continuing with our previous example, we can see that a 9.06kW system would cost approximately $27,452 to install.

= 9,060watts x $3.03/watt

= $27,452

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 an average – installation prices can easily go as high as $3.50+/watt for premium equipment and high quality installers.

Solar Incentives

Solar Energy Incentives Canada

Major Program: Solar Electric Rebate

Savings: 40% or $1.00/watt

Prince Edward Island has the largest provincial solar energy incentive available in the Country.

These factors are important because they reduce the upfront system costs. We’ve scored Prince Edward Island 15/20 for this section.

Some important things to keep in mind:

  • Per Watt. Rebates in the province are awarded based on the size of the system you install, in units of watts. Jump back up to the System Sizing section if you don’t understand what this means.
  • Eligible Costs. Rebates have a maximum funding amount that is based on a percentage of total eligible expenses. In general, eligible expenses include the full cost of materials and installation, but not tax.
  • Qualified Installation. Finally, rebates in PEI must meet certain installation qualifications. This includes the stipulation that the system must be installed by a qualified efficiencyPEI Network of Excellence contractor.
  • Application. Rebate applications, including all paperwork, should be handled entirely by your installation company.

Rebates & Tax Breaks

The largest solar rebate program in Prince Edward Island is the Solar Electric Rebate Program administered by efficiencyPEI.

This program allows property owners to earn a cash rebate of $1.00/watt for residential solar power installations up to a maximum rebate amount of $10,000.

Here is what the savings would look like for a 9.06kW system:

(9,060 watts) x ($1.00/watt) = $9,060

Thus, the cost of a 9.06kW system would decrease from $27,452 to $18,392. Go back to the Common Solar Questions section if you’re not sure where these numbers are coming from!

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.

Other Clean Energy Incentives

There are at least 7 other energy incentive programs available in PEI. While not considered in our solar rankings, many homeowners choose to leverage these (i.e., home energy efficiency incentives) around the same time they switch to solar.

Natural Factors

Solar Energy Production Potential Canada

Production Potential: 1104kWh per kW per year

Prince Edward Island is scores somewhere in the middle in terms of the natural factors that influence the maximal amount of energy that a system can produce. We’ve scored Prince Edward Island 16.5/20 for this section.

Solar Irradiance

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

According to data from Natural 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 irradiance potential map for Prince Edward Island:

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
  • Summerside would produce about 1,125 kWh/yr
  • Stratford would produce about 1,100 kWh/yr
  • Cornwall would produce about 1,106 kWh/yr
  • Montague would produce 1,087 kWh/yr

Recall that this is the number we used in the System Sizing section!

(maps and solar irradiance data for all other provinces and territories can be found on our Solar Maps page.)

Utility Policies

Utility & Solar Connection Policies Canada

Connection Policy: Net Metering

Rate Design: $0.17/kWh, Reverse Tiered

Prince Edward Island scores in front of many provinces when it comes to utility-related factors.

Utility factors determine how much money your utility will pay you for the power you produce, along with how much money you will save on your power bill by reducing your usage. We’ve scored Prince Edward Island 25/30 for this section.

Interconnection Policy

Net Meter Bi-directional Meter

Net Metering is one of the most important policy mechanisms that makes solar a feasible energy generation option.

Net Metering essentially means that you earn credits for the excess energy that you produce, which can then be used at a later time. It’s common to produce excess energy during the day and summer but not enough at night and during the winter – so this policy is important!

Good net metering policy allows you to earn full credits for your excess energy which can be carried month-to-month. Bad net metering policy allows you to earn only partial credits for excess energy and credits can’t be carried forward month-to-month.

Disconnecting from the grid also means that you won’t be able to participate in your utility’s net metering program.

Prince Edward Island’s Net Metering Policy falls in the “good” category for net metering policies. It allows for systems up to 100kW in size to be connected to the grid and credits can be carried forward month-to-month.

However, it’s important to note that net-metering credits in PEI expire annually 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 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!

Electricity Prices

Electricity Costs for Solar Canada

Prince Edward Island is one of the better provinces for solar with respect to electricity prices – higher prices mean higher savings potential.

Based on a monthly usage of 1,000kWh, the average total cost of electricity in Prince Edward Island is $0.174/kWh (this number includes both fixed and variable costs).

This number is higher than the Canadian average of $0.138/kWh (excluding the territories), meaning that property owners in Prince Edward Island have a lot of potential savings!

(methodology and data on other provinces and territories can be found on our Electricity Prices page.)

Utility Bill Rate Design

Electricity Bill Rate Design

Good electricity rate design allows you to save money when you save energy. This might sound intuitive – but not all provinces are same. Superior designs have low fixed monthly fees and tiered electricity rates. Inferior designs have high fixed fees and flat electricity rates.

Prince Edward Island scores in the worst province when it comes to these factors – having tiered rates decrease in price the more energy you use, and fixed monthly fees of $25.

For example, reducing your electricity bill from 1,500 to 750 kWh per month will save you 54% on your electricity bill in British Columbia, 48% in Nova Scotia, but only 45% in Prince Edward Island!

Note that fixed monthly fees don’t disappear even if you switch to solar – you’ll pay them as long as you remain connected to the grid. But this isn’t a bad thing – $25/mo is a small price to pay for using the grid as your back-up energy source!

(methodology on our Electricity Prices page.)

Average Fixed Costs Electricity Canada
Average Fixed Costs of Electricity in Canada

The only way to completely remove your fixed costs is to go off the grid, something most homeowners in PEI don’t do because of high battery costs.

Disconnecting from the grid also means that you won’t be able to participate in your utility’s net metering program.

System Financing

Solar Energy Financing Canada

Upfront Cost: $3.03/watt

Financing: Energy Loan

Prince Edward Island is the middle when it comes to financial factors because of moderate up-front costs and some available financing options. We’ve scored Prince Edward Island 19/30 for this section.

Cost of Installation

The upfront cost of installation is obviously one of the largest factors that determine whether or not a person is going to switch to solar. The current average price range in Prince Edward Island is about $2.73-$3.33/kW.

(not sure what this number means or how to use it? Jump back up to the Common Questions section.)

However, the price can easily be higher or lower depending on the size of the system, the complexity of the job, the type of equipment used, and even on the quality of your installation company.

In general, aiming for the cheapest price shouldn’t be your goal. Most solar panels are guaranteed to last 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. If you get a quote through us, we’ll connect you with a pre-vetted installer!

PACE Programs

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 on your property tax bill as a Local Improvement Charge (LIC). The only eligibility is that you need to own a certain portion of your home.

Unfortunately, PEI does not currently have any PACE financing options available – but Stratford and Charlottetown recently made changes to its legislature to allow for PACE programs within the province. So, a program may soon be on the way!

Other Energy Financing

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 mortgage (for new builds), or through energy loans.

Other options exist for Prince Edward Island homeowners:
