Frequently Asked Questions

What is the typical cost of solar panel installation in Ontario?

 

The average cost of installing solar panels in Ontario ranges from $2.50 to $3.50 per watt, depending on system size, roof type, and equipment brand. For a typical 7 kW residential system, total installation costs are usually between $17,000 and $25,000 before tax. Costs can be reduced through rebates and tax incentives.
How much will solar panels save me on my electricity bill in Toronto?
Homeowners in Toronto can expect to save 40%-80% on their annual hydro bills, depending on system size and energy usage. A well-sized solar array can produce over 8,000 kWh per year, cutting thousands of dollars from utility costs over its lifetime.
Are there government incentives or rebates for solar in Ontario?
While Ontario no longer offers feed-in-tariff programs, homeowners can benefit from federal tax incentives, zero-interest loans, and net-metering credits. The Canada Greener Homes Loan and Greener Homes Grant both support solar installations that improve energy efficiency.
Is my roof suitable for solar panel installation in the GTA?
A suitable roof for solar typically faces south, southeast, or southwest, has minimal shading, and is in good condition. Solar Plus Solution offers free roof assessments to check tilt, material, and structural integrity before installation.
Which direction and angle should solar panels face in Southern Ontario?
For optimal production, panels should face true south with a 30-40 degree tilt. East- or west-facing panels still generate around 85-90% of maximum output, making them good alternatives for complex roofs.
How long does the solar panel installation process take in Ontario?
Most residential solar installations take one to two days on-site. The entire process—including design, permits, inspections, and utility approval—typically spans 4-8 weeks.
What size solar system do I need for my home in Toronto?
An average Toronto home consuming 9,000 kWh per year may need a 7-8 kW solar system. Solar Plus Solution performs customized load analyses to determine ideal sizing for your consumption and roof space.
Will installing solar panels damage my roof or void my warranty?
Properly installed solar panels do not damage roofs. We use engineered racking systems and professional flashing to maintain waterproofing. Most roof warranties remain valid after solar installation when performed by certified installers.
What is net-metering and how does it work in Ontario?
Net-metering allows homeowners to send excess solar electricity to the grid and receive energy credits. These credits offset your electricity use during the night or cloudy days, effectively lowering your hydro bill.
Do solar panels work during cloudy days or in winter in Ontario?
Yes. Solar panels still produce power on cloudy days—typically 30%-50% of peak output. Even in winter, Ontario receives enough sunlight for effective generation thanks to cold temperatures improving panel efficiency.
