The City of Toronto offers complimentary consultations and guidance to residents and businesses to support the installation of solar PV systems on Toronto’s homes and buildings. See below for more details on the services offered.

Experienced City staff have managed the installation of more than 100 solar photovoltaic (PV) systems installed on a variety of City-owned buildings, including community centres, work yards, libraries, and EMS stations. The systems range in size from 3kW to 500 kW.

TransformTO, Toronto’s climate action strategy identifies several key goals, including that 75 per cent of energy must come from renewable or low-carbon sources by 2050.

Solar panels convert energy from the sun into electricity. This electricity then goes through an inverter, where it is converted into a usable form of energy for your building.

The system will be tied to Toronto Hydro’s electricity grid through its Net Metering Program, where the electricity generated by the solar panels is consumed by the building. Any excess electricity will be exported to the grid for future credit.

  • Reduce your utility bill & mitigate the impact of rising electricity costs
  • Reduce your building’s GHG emissions and carbon footprint
  • Increase the value of your building
  • Toronto receives more than 2,000 hours of sunshine each year, the fuel is renewable and free
