Why Solar

How Solar Works in Ontario

Net Metering

Your system powers your home first. Extra power goes to the grid and earns bill credits that carry forward for 12 months.

Load Displacement

Your system powers your home and does not export. This path qualifies for the Home Renovation Savings rebate.

Time-of-Use & ULO

Ontario prices change by time of day. A battery shifts cheap overnight power to the expensive evening peak.

12 kW Simplified Limit

Since May 1, 2026, homes can connect larger systems through the simplified process.
