How Long Does It Really Take to Go Solar in Canada?

How Long Does It Really Take to Go Solar in Canada?

Making the switch to solar or heat pumps is exciting but many Canadian homeowners are surprised by how long the process can actually take. From your first consultation to your final rebate cheque, the clean energy journey includes several steps, each with its own timeline, paperwork, and potential delays.

In this post, we break down each phase of a typical solar or heat pump project in Canada so you can plan with realistic expectations—and avoid the most common holdups.

Phase 1: The Energy Audit (1–3 Weeks)

Before applying for most rebates, your home must be evaluated through a certified energy audit. This helps identify what upgrades qualify and provides the “before” data required for reimbursement.

• Booking: Depending on your province, it can take 5 to 14 days to schedule an energy advisor.
  
• Audit: The inspection itself typically lasts 2–3 hours.
  
• Results & Report: After the audit, expect a wait of 3–10 business days for the official report, which you’ll need to submit rebate applications or start your install.
  

Tip: In provinces like Ontario, where demand is high, book your energy audit early to avoid bottlenecks.

Phase 2: Permits and Paperwork (2–4 Weeks)

Municipal permits and utility approvals are required before installation begins. These vary by province and city, but typically include:

• Zoning or building permits (especially for roof-mounted systems)
  
• Electrical safety authorization
  
• Interconnection request with your local utility (e.g., Hydro One)
  

This stage is often where projects slow down. Some municipalities can process permits in a few days, while others may take over three weeks—especially in spring and summer when applications surge.

Pro Tip: Work with installers who handle permits and approvals on your behalf. They often have faster communication channels with local officials.

Phase 3: Equipment Sourcing & Scheduling (2–6 Weeks)

Once approvals are in, your installer will schedule your installation and order the equipment—solar panels, heat pumps, inverters, racking systems, and more.

Factors that can affect this stage:

• Availability of parts: Certain inverters or premium panel brands may be on backorder.
  
• Weather: Installations can be delayed due to rain, wind, or extreme cold, especially in provinces like Alberta or Manitoba.
  
• Installer backlog: Some contractors book 4–6 weeks out during peak season.
  

Phase 4: Installation (1–3 Days)

This is the fastest part of your journey. Solar panel installations typically take 1–2 days, while heat pump installs can take 1–3 days, depending on system complexity and home size.

Most contractors aim to complete this step quickly to avoid permitting lapses or rebate delays.

Phase 5: Final Inspection & Utility Connection (1–4 Weeks)

After installation, your system must be inspected and approved before it goes live. This often includes:

• Electrical safety inspection (e.g., ESA in Ontario)
  
• Final interconnection with the utility (e.g., Hydro One, BC Hydro)
  

Some utilities can approve interconnection within a few days, but others—especially during peak season—may take up to 30 days. No power can flow back to the grid (and no net metering starts) until this step is complete.

Phase 6: Rebate Application & Payment (6–12 Weeks)

Once the system is connected and you’ve completed a post-installation energy audit, you can apply for rebates. Depending on the province:

• Canada Greener Homes Grant payments can take 8–12 weeks.
  
• Provincial programs (like BC’s CleanBC or Quebec’s RénoClimat) may process faster—around 4–8 weeks.
  
• Loan approvals (e.g., interest-free Canada Greener Homes Loan) can delay if forms are incomplete.
  

Avoidable Delay: Many homeowners miss deadlines or submit incomplete forms. Be sure to gather all documentation—receipts, audit reports, and photos before submitting.

Total Time Estimate: 3 to 6 Months

Project Stage	Estimated Time
Energy Audit	1–3 weeks
Permits & Utility Approvals	2–4 weeks
Scheduling & Equipment Procurement	2–6 weeks
Installation	1–3 days
Final Inspection & Grid Connection	1–4 weeks
Rebate Processing	6–12 weeks
Total Timeline	~3 to 6 months

How to Shorten Your Timeline

• Choose a full-service installer who handles all paperwork and permitting.
  
• Start early, especially if you want to complete your install before winter.
  
• Use digital tools (like Solenery’s lead intake and tracking system) to stay organized and avoid missed documents.
  
• Book your energy audit early. It’s a prerequisite for everything else.
  

Final Thoughts

Clean energy projects in Canada can be life-changing but they also take time. By understanding the full timeline and preparing ahead, you can avoid unnecessary delays, make informed decisions, and take full advantage of the rebates and incentives available in 2025.
