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.
