Net metering, 1:1 credits, 12-month rollover. Each kWh you export offsets a kWh you buy later. See the Ontario page for the full rules.

How much could solar save on a Hydro One bill?

In our model, a sample Barrie home with a $180 monthly bill on the Time-of-Use plan saves about $1,310 in the first year with a 6.9 kW system, paying back in 13.9 years. Your roof and usage will change the result.

Which Hydro One rate plan works best with solar?

For our sample household, the lowest bill after solar was on Ultra-Low Overnight ($69 a month on average). Plans reward different habits, so compare them with your own usage.

Do I need Hydro One's permission to install solar?

Yes. Your installer applies to connect the system to the grid, and an electrical inspection is required before it is switched on. The utility may change your meter.
