The average residential solar setup in Canada typically ranges from 6–8 kW, amounting to a pre-incentive cost of roughly $25,000–$45,000. The total cost varies based on household power needs, regional electricity rates, and roof layout. For instance, monocrystalline solar panels are more efficient and come with a higher price tag than polycrystalline panels. You might see prices ranging from $2. 50 per watt for the entire system, depending on your province. Before you can figure out the cost of a solar project, you need to know how much power your home actually uses. Knowing these price differences will enable you to make an educated determination about your solar options.
