Residential Solar Sizing & Siting
Ontario homeowners can take advantage of net metering programs offered by all major local distribution companies (LDCs) including Hydro One, Toronto Hydro, Alectra Utilities, and Elexicon. Net metering allows you to send surplus solar energy to the grid in exchange for credits that offset your future electricity usage.
Most residential solar systems in Ontario range between 6 kW and 12 kW in size, depending on roof space and household energy use. With average residential electricity prices rising, a system sized correctly can eliminate your energy bill entirely (except for base customer connection charges).
Financing is a primary driver of residential adoption. Cities like Toronto and Ottawa offer PACE-style financing programs (such as HELP) linked directly to your property taxes, helping make solar installations cash-flow positive from day one.

Frequently Asked Questions
How does Ontario Net Metering work?
Under Ontario's net metering regulation, you receive credits on your electricity bill for the surplus power you send back to the grid. These credits can be used to offset the cost of electricity you pull from the grid when your panels aren't producing. Credits can be carried forward for up to 12 months.
Do solar panels work in Ontario winters?
Yes. While production is lower during winter due to shorter days and snow cover, cold temperatures actually improve solar panel efficiency. Light snow will melt off quickly as the panels are dark and tilted to catch the sun.
Is an ESA permit required in Ontario?
Absolutely. All solar installations in Ontario must be inspected and approved by the Electrical Safety Authority (ESA) to ensure compliance with the Ontario Electrical Safety Code.
