Questions
Hydro-Québec and solar: FAQ
- Can Hydro-Québec customers get credit for solar power they send to the grid?
- Hydro-Québec net metering: kWh banked for 24 months. Each kWh you export offsets a kWh you buy later. See the Quebec page for the full rules.
- How much could solar save on a Hydro-Québec bill?
- In our model, a sample Montréal home with a $180 monthly bill on the Rate D plan saves about $1,773 in the first year with a 19.4 kW system, paying back in 18.1 years. Your roof and usage will change the result.
- Do I need Hydro-Québec'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.
