The number of solar panels needed depends on your energy usage, location, and panel wattage. An average Canada home using 10,632 kWh per year typically requires 15 to 22 panels (assuming 400W panels and 5 peak sunlight hours per day). To get an exact estimate, divide your annual energy consumption by your area's solar production ratio and panel wattage.

Yes, solar panels can significantly reduce electricity bills, provide energy independence, and offer long-term savings. Factors like electricity costs, available incentives, and sunlight hours determine their value. In states with high electricity rates, solar panels often pay for themselves in 5-8 years and continue generating savings for 25+ years.

As of March 2025, the average cost of solar panels in Canada ranges from CAD 2.50 to CAD 3.50 per watt (W). This means a typical 5-kilowatt (kW) residential solar system would cost between CAD 12,500 and CAD 17,500 before incentives. In Ontario, the cost per watt is between CAD 2.60 and CAD 3.40, which translates to a total pre-installation cost of around CAD 26,000 to CAD 34,000 for a 10 kW system.
It's important to note that actual costs can vary based on factors like system size, equipment quality, and installation specifics. For the most accurate estimate, consider obtaining quotes from multiple local installers.
