Choosing an installer can be overwhelming if you don’t know where to start. Read the below steps to learn how to go solar.

  1. Check the solar potential of your rooftop using the SolarTO Map.
  2. Assess the age and condition of your roof. If your roof is older than ten years, have the condition assessed by a roofer.
  3. Review your electricity bills and add up your usage (in kWh) over 12 months to determine your annual electricity usage. To see how much electricity can be offset by solar, compare your usage with the annual solar electricity generation estimated by the SolarTO Map.
  4. Taking steps to reduce your energy consumption before installing solar can save you money on energy costs and reduce the number of solar panels you need. See the Incentives and Rebates to Green Your Home to explore options.
  5. Obtain at least three proposals from different solar installers. Refer to the Solar Directory to find installers serving the GTA.
  6. Your selected solar installer will submit a Distributed Energy Resource (DER) Pre-Assessment application to Toronto Hydro to confirm grid capacity. If the DER is approved, continue to the next step.
  7. Your selected installer will conduct a site inspection to determine the best system size and location for your panels. You will review the design and sign the proposal.
  8. Ask your installer if your roof requires structural reinforcement or replacement. Your installer will arrange the structural review of your roof as part of the Building Permit requirements.
  9. Toronto Hydro will complete a technical site assessment before you submit your Offer to Connect and Connection Cost Agreement and final payments.
  10. Explore available financing and incentives by referring to the Financing & Incentives tab.
  11. Your solar installer will file applications for the required permits, finalize the design, procure the equipment and install the system.
  12. Once your installer is ready to connect the system to the grid, they will submit a request to isolate.
  13. The Electrical Safety Authority (ESA) will complete their inspection of your system and provide a certificate. The certificate is mailed to Toronto Hydro.
  14. Toronto Hydro will complete a final inspection and install a bi-directional meter.
  15. You’re ready to start harnessing the power of the sun!
