Context
Solar in Canada
Canada receives significant solar irradiance in many regions despite its northern latitude. Ontario, Alberta, and British Columbia have established net metering programs that allow residential owners to offset consumption with grid-exported generation. Provincial incentives and federal programs such as the Canada Greener Homes Grant have historically supported equipment and installation costs, though program availability changes over time.
The Natural Resources Canada PV potential map is a useful starting point for understanding site-specific irradiance before engaging an installer.
Maintenance Overview
Keeping Panels Productive
A residential PV system requires minimal intervention once installed. Annual tasks typically include visual inspection for damage, checking electrical connections, reviewing inverter performance logs, and cleaning panels in areas with significant particulate accumulation. In snowy climates, accumulated snow slides off most tilted arrays naturally but can temporarily reduce output during heavy events.
Most manufacturers specify panel degradation rates in their product datasheets. Reviewing inverter data against those projections annually helps identify underperforming strings early.
