HOW MUCH DO SOLAR PANELS COST IN ONTARIO?

Solar panel installation in Ontario typically costs between $15,000 and $30,000 for most homes. The final price depends on system size, roof layout, equipment, electrical requirements, and whether battery storage is included. Below, we’ll break down the main cost factors and what homeowners can expect before getting a quote.

Average Solar Panel Cost by System Size

SOLAR PANELS COST IN ONTARIO

Most homes in Ontario install solar systems between 5 kW and 10 kW, based on their annual electricity usage, available roof space, and energy goals.

Smaller System

5 kW System

$15,000 – $20,000

Best for smaller homes or lower electricity usage.

Estimated output: 5,500–6,000 kWh/year
Most Common

7 kW System

$20,000 – $25,000

Suitable for many average Ontario homes.

Estimated output: 7,500–8,500 kWh/year
Larger System

10 kW System

$25,000 – $30,000+

Best for larger homes or higher electricity usage.

Estimated output: 10,000–12,000 kWh/year

System size is typically based on how much electricity your home uses annually. For example, a home with a monthly hydro bill of $120–$180 will usually fall within the 5 kW to 7 kW range, while higher usage homes may require larger systems. Larger systems cost more upfront but generate more electricity, which can lead to greater long-term savings through net metering. However, system sizing should be based on actual usage rather than maximizing panel count.

Without Solar

  • Full reliance on utility power
  • Exposure to rising electricity rates
  • No long-term energy cost control

With Solar

  • Lower monthly electricity bills
  • Net metering credits
  • Greater long-term energy stability

The Cost of Solar Panels

What Affects Solar Panel Cost in Ontario

System Size

The size of your solar panel system is the most significant factor affecting the cost.

Larger systems that generate more electricity will naturally cost more. For example, a 7,500-watt system can cost between $18,750 and $26,250, depending on various factors​.

Installation Type

Roof-mounted installations are generally more cost-effective compared to ground-mounted systems due to less material and labor requirements.

Roof-mounted systems utilize existing structures, making the installation process simpler and less labor-intensive.

Panel & Inverter Type

Panel Type: Polycrystalline panels are cheaper but less efficient, while monocrystalline panels are more efficient and costly but offer better long-term savings.

Inverter Type: Microinverters are the most expensive but optimize each panel individually. String inverters are more affordable but less efficient if shaded. Power optimizers provide a cost-effective middle ground.

Warranties

Opting for extended warranties on equipment and installation can increase the upfront cost but provides long-term savings and peace of mind. Solar panels typically come with a performance warranty of 25 years, while inverters may have shorter warranties.

Extended warranties cover potential defects and performance issues, ensuring your investment remains protected.

Location & Rebates

Different municipalities in Ontario offer various incentives that can reduce the overall cost.

Programs like Toronto’s Home Energy Loan Program (HELP), Ottawa’s Better Homes Ottawa Loan Program, and Guelph’s Greener Homes Program provide financial support for solar installations​.

Expertise & Labour

The experience and reputation of the installation team can affect costs.

Experienced and reputable installers may charge more but provide higher quality installations, reducing future issues and maximizing system efficiency and lifespan.

Solar Panel Installation Rebates

Solar Incentives and
Rebates in Ontario

Solar incentives and rebates can significantly reduce the upfront cost of installing solar panels in Ontario. While programs change over time, there are several options that help improve overall return on investment. Below are some of the key programs available:

The Canada Greener Homes Loan offers interest-free loans of up to $40,000 to help Canadians make their homes more energy efficient and comfortable. Homeowners are required to complete a pre-retrofit EnerGuide evaluation to participate in the program.

The Better Homes Ottawa Loan Program (BHOLP) is a City of Ottawa initiative designed to support home energy efficiency retrofits. Its goal is to help local residents reduce energy consumption and greenhouse gas emissions.

This program allows homeowners to offset their electricity costs by exporting excess solar power back to the grid, providing credits that reduce monthly electricity bills.

Some local utilities and municipalities offer additional rebates and incentives for solar installations. These programs vary by region and can significantly impact the overall cost of your solar project. Contact us to find out more about local rebates that might be applicable for your home or business!

Solar Panel Savings & ROI

How Much Can You Save with Solar Panels in Ontario?

Solar savings in Ontario depend on your electricity usage, system size, roof conditions, and net metering credits. For many homeowners, the biggest value comes from reducing monthly electricity bills over the life of the system.A properly sized residential solar system can often offset a meaningful portion of annual electricity costs. Over 25+ years, that can add up to significant long-term savings, making solar panel installation a smart long-term investment.

Monthly electricity bill $200
Annual electricity cost $2,400
Estimated yearly solar savings $1,500 – $2,200
Estimated 25-year savings $37,500 – $55,000
Typical payback period 8–12 years

These figures are examples only. Your actual solar savings depend on your hydro usage, roof layout, system size, net metering credits, and electricity rates. A custom solar assessment can show your projected annual savings, payback period, and long-term return on investment.

NET METERING CREDITS

How Net Metering Works in Ontario

Net metering is a billing system in Ontario that allows homeowners with solar panels to earn energy credits for the electricity they send back to the grid. When your solar system produces more electricity than your home is using, the excess energy is exported to the grid. Your utility then credits your account for that energy. These credits can be used later when your home needs electricity — such as at night or during winter months. Instead of storing energy with batteries, net metering lets you store value in the form of credits, helping balance your electricity usage over the entire year.

How net metering works-1

Solar panels generate electricity​

Your home uses that electricity​

Extra energy is sent to the grid​

You receive energy credits​

01

Solar panels generate electricity

Your solar panels convert sunlight into electricity while the sun is shining. This electricity can be used to power your home.

02

Your home uses that electricity first

  The energy your system produces is used by your home before drawing power from the grid. This helps reduce how much electricity you buy from your utility.

03

Extra energy is sent to the grid

 When your system produces more electricity than your home needs, the excess is sent back to the electrical grid.

04

You receive energy credits

 Your utility tracks the excess electricity and applies credits to your account. These credits help offset future electricity use.

Should You Switch to Solar?

Benefits of Switching to Solar

Below, we explore the potential savings, return on investment, and additional benefits of going solar.

Savings & ROI

Switching to solar can save homeowners up to $30,000 over 25 years, with systems paying for themselves in 7-10 years through energy savings and incentives. Savings vary by energy use and rates, and solar systems also increase property value.

Environmental Impact

Solar energy is a clean, renewable source of power that reduces your carbon footprint and reliance on fossil fuels. By switching to solar, homeowners can significantly decrease their greenhouse gas emissions, contributing to a healthier planet.

Energy Independence

Generating your own electricity reduces dependence on the grid and protects against rising energy costs. Solar energy provides a stable and predictable energy source, insulating homeowners from fluctuating electricity prices.

Energy Security

Solar power provides a reliable source of energy during power outages and emergencies, ensuring that homes remain powered even when the grid goes down. This is particularly beneficial in areas prone to natural disasters or frequent power interruptions.
