How much will a solar panel system installation cost?

There are many great reasons why homeowners consider generating their own electricity with solar.

  • Lower your carbon footprint
  • Use clean power to breathe clean air
  • Charge an electric car
  • Power an electric heat pump
  • Move towards a net-zero lifestyle
  • Independence from the grid
  • Save money on utility bills and/or on gas for your car
  • Earn back the investment on solar through savings on hydro bills
  • Take advantage of the federal government rebate
  • Increase your property value

Any size system will provide these benefits. The right size for you depends on how much you want to maximize the benefits of solar to meet your own personal goals.

The amount of electricity a system can generate depends on a few factors including where you live, how much sun you get throughout the year as well as the size, orientation, and shading of your solar panels.

Net metering allows you to take full financial advantage of all your generated power as long as the generation is equal to, or less than, your annual electricity use. In general, the larger the size, the quicker the payback from savings on your hydro bills. Here are a few potential business case summaries of net metering systems located in southern Ontario with average sunlight conditions. Many factors affect installation costs and payback periods so these are only very general estimates. 

Small System – 15 to 20 Panels

  • Size: 5kW to 7kW
  • Annual electricity generated: 5,250kWh to 8,000kWh
  • Suitable for current electricity bills of $50 to $80 per month
  • Cost of solar panel system installation: $17,000 to $25,000 
  • Payback: 14 to 15 years

small 2022

Medium System – 20 to 35 panels

  • Size: 7kW to 12.5kW
  • Annual electricity generated: 8,000kWh to 15,000kWh
  • Suitable for current electricity bills of $80 to $200 per month
  • Cost of solar panel system installation: $25,000 to $50,000
  • Payback: 12 to 14 years

Large System – Over 35 Panels

  • Size: 12.5kW or more
  • Annual electricity generated: 15,000kWh or more
  • Suitable for current electricity bills over $200 per month
  • Cost of solar panel system installation: $50,000 or more
  • Payback: 10 to 12 years

Large 2022

Solar installations easily last 35+ years so all savings earned once the system has paid for itself is like money in your pocket. In the long run, solar helps the environment, contributes to the clean energy economy, and saves you money.

Guelph Solar Net Metering IconNet Metering

Lower Your Hydro Bill Using Clean Power from the Sun


We all want lower utility bills. With Net Metering you can reduce your hydro bill substantially.

Net Metering is a utility billing mechanism available in Ontario that offers a credit to residential and business customers, who are making excess electricity with their solar panel systems and sending it back to the grid. This results in lower hydro bills year-round.

How Does Net Metering Work?

When you have a rooftop solar system, the electricity it produces is used right in your own home as it is being generated. Your solar can often generate more electricity than you consume during daylight hours. This excess can be sent to the grid in exchange for a credit on your bill. In the evenings you will purchase it back from the grid. 

With net metering, the homeowner is only billed for the “net” energy used each month, that is, the difference between the energy produced by the solar power system and the energy consumed by the house over the monthly billing period. 

In the summer, you will produce more electricity than you will use. The excess will be sent to the grid, resulting in a credit balance on your hydro account. You can use this credit in the winter when you will be using more electricity from the grid because of shorter daylight hours.

Off-Grid & Zero Export Systems

Guelph Solar designs and installs custom off-grid systems with battery backup. Off-grid systems are ideal for cottages or remote properties that have no access to power or where power would be too expensive to install.

We also install zero export solar panel systems with or without batteries. Zero export systems stay connected to the grid, however, the solar energy produced is consumed in the moment, or stored in a battery. A zero export meter is installed to ensure no power is ever exported to the grid. A zero export system is ideal for properties that consume high amounts of energy during the day. Producing your own solar energy is the cheaper and environmentally friendly option.

Guelph Solar Sun IconFAQ

Here are some common questions and answers. Please get in touch if you have other questions which are not covered here.

Replacing your shingles right before a solar install is a fantastic time to do it because the shingles will last many years longer with panels protecting them. That said, if your shingles are in good condition, you will not need to replace them, as the panels will keep them protected and in good condition for many years.

Yes. We can arrange financing, however, we recommend you first attempt to arrange financing from your preferred financial institution - your mortgage provider, typically - as they will already have a credit profile for you, and you will likely get the best possible interest rate.

  Go to top...  

Yes. The panels and solar optimizers come with a 25-year warranty, while the inverter has a 12 year, extendible warranty.

  Go to top...  

Yes an older home can support solar. Before installing we perform a structural assessment and determine if any work is needed.

Many reviews are showing that the value of a property with solar is increased. In the United States, the value of the home is increased by $4 per watt of installed solar power (New York Times, Feb, 2016). More research is needed in Canada, but the trend is here too!

Maximum production occurs when the sun is highest. On a daily basis, production starts at sunrise, reaches its peak around noon, then declines until it reaches zero at sunset.  During the year the sun provides the most energy around the summer solstice (June 20) and the least around the winter solstice (December 20). Weather, snow, shading and other factors will impact production. After we conduct an assessment of your roof, we will show you our predicted month by month energy production for your system.

In the event of a power outage without a battery the inverter will shut down due to anti-islanding regulations needed to protect line workers. Furthermore, in order to output power this grid-tied inverter needs to see 240 volts - which is typically in the form of the grid. However, the good news is if you have a battery such as the Tesla Powerwall, then the inverter will be able to talk with it instead of the grid and you will be able to power your home in the event of an outage. Please contact us in regards to adding batteries or a zero export meter to your system!

There are a few factors that determine how great a roof will be for solar, whether you are interested in NetMetering, pool or a battery system. Roof surfaces which face south do best, but we often install on other surfaces as well, and the systems do very well. We use a solar Pathfinder to examine how much shade falls on your roof in different areas throughout the year. We then use this information to determine how much electricity your array will produce each year. Get in touch with us and we can do a free assessment of your roof online.

15% of your annual revenue for a solar MicroFIT system is made from January to March, it could be more than $700 per year if there was no snow on your panels at all. A portion of your snow clearing cost can be written off as a business expense under your solar contract. For net metering systems, clearing snow will help you save money by reducing your electricity bills.

$500 (base cost) for the season: This would include a clearing of your driveway every time there is a snow event with at least 6 cm. This also includes having your panels cleared after a snow fall when several days of sun is predicted (about twice a season).

$40 (base cost) per driveway clearing.

$75 (base cost) per solar panel clearing.

We encourage our customers to consider heating their pools with air-source heat pumps and to use their roofs to power their heat pumps and homes all year round. Using your roof to heat your pool for just a few months a year would be a missed opportunity when we have high-quality solar electric solutions with great business cases.  Solar electric power for your home can heat your pool, power your lights and refrigerator, and charge your car.
